Optimal Duration of Cold and Heat Compression for Forearm Muscle Biomechanics in Mixed Martial Arts Athletes: A Comparative Study.

BACKGROUND Cold and heat therapies for recovery in sports are commonly used, including in the mixed martial arts (MMA). The Game Ready (GR) device can be used for local monotherapy with either heat or cold and for contrast therapy. This study aimed to compare the effects of duration of cold and heat compression on biomechanical changes in the forearm muscles of 20 healthy mixed martial arts athletes. MATERIAL AND METHODS Twenty MMA volunteers (26.5±4.5 years old) underwent 3 different phases of the GR: (1) stimulation time 10 min (eGR-10, GR experimental group), (2) 10 min (cGR-10, sham control group) and (3) 20 min (eGR-20, GR experimental group). The following outcomes were assessed: muscle tone (T), stiffness (S), flexibility (E), pressure pain threshold (PPT), microvascular response (PU), and maximum isometric strength (Fmax). All measurements were performed before GR (rest) and after GR stimulation (post). RESULTS Both eGR-10 and eGR-20 significantly improved outcomes T (p<0.001), S (p<0.001), E (p=0.001, and p<0.001, respectively), PPT (p<0.001), PU (p<0.001), and Fmax (p<0.001). Notably, eGR-20 exhibited superior improvements in PU, Fmax, and PPT, with larger effect sizes (p<0.001). While eGR-10 demonstrated more pronounced reductions in T and S (p<0.001), these results underscore the potential for tailored GR therapy durations to optimize specific recovery goals for MMA athletes. CONCLUSIONS GR stimulation affects muscle biomechanical changes, pain threshold, muscle strength, and tissue perfusion. The study results suggest that 10 min of GR stimulation is sufficient to achieve changes that can be used to optimize recovery for MMA athletes.

Is Shock Wave Application Effective on Various Chronic Wounds in the Geriatric Population? Preliminary Clinical Study.

Purpose: Extracorporeal shock wave therapy (ESWT) is a beneficial adjunct modality for chronic wounds. Limited research has been conducted on pressure ulcers (PUs), while the majority of studies have focused on diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). This study aimed to evaluate the short-term effects of radial ESWT in older adults with chronic wounds. Patients and Methods: This study involved a total of 31 wounds: PUs (n=22), VLUs (n=7), and DFUs (n=2). A single radial ESWT was performed with 300 + 100 shocks per cm2, pressure of 2.5 bar, energy of 0.15 mJ/mm2, and frequency of 5 Hz. Assessments using digital planimetry and clinical methods, utilizing the Wound Bed Score (WBS) and the Bates-Jansen Wound Assessment Tool (BWAT) were performed before the radial ESWT application (M0) and one week after (M1). Results: A significant wound decrease in planimetry was noted (pre-ESWT vs post-ESWT), with wound area from 9.4 cm2 to 6.2 cm2, length from 6.4 cm to 3.9 cm, and width from 2.8 cm to 2.1 cm (p<0.001). Additionally, a substantial clinical improvement was noted in both the WBS with a 31.25% increase and the BWAT with a 20.00% increase (p<0.001). It was also found a significant correlation between the planimetric and clinical outcomes for both tools: WBS (r=-0.446, p=0.012) and BWAT (r=0.327, p=0.073). Conclusion: The ESWT application yields substantial immediate clinical effects that support the healing of chronic wounds in older adults. Even a single ESWT session can prove to be clinically effective and beneficial in the management of chronic wounds.

Dry Needling with the Use of FRSc Technique in Addition to Standard Rehabilitation Program for Chronic Low Back Pain: A Randomized Controlled Trial Using Both PROMs and Measurement Tools.

Purpose: Dry needling (DN) has gained popularity for musculoskeletal conditions, but its commercial use often surpasses scientific evidence. The novel Five Regulatory Systems Concept (FRSc) of DN shows potential therapeutic mechanisms, including chronic low back pain (LBP). However, rigorous clinical assessment with patient-reported outcome measures (PROMs) and objective measures are necessary. This study aimed to evaluate the effect of DN according to pain levels, postural control and selected gait parameters in patients with chronic LBP. Patients and Methods: This prospective, double-blinded, randomized controlled study involved 30 patients with LBP allocated in the experimental (n=15, rehabilitation+ FRSc DN) or control group (n=15, rehabilitation + sham DN). The Roland-Morris questionnaire (RMQ) and Visual Analog Scale (VAS) were used as PROMs. Moreover, the posturography method for posture and balance control and the treadmill for gait analysis were used as objective tools. Measurements were taken before and immediately after the intervention and during 1- and 3-month follow up. Results: There was a statistically significantly greater improvement in the RMQ in the experimental group compared to the controls (p=0.923 before and p<0.001 after treatment, as well as p<0.001 after 1 and 3 months). Despite the favorable analgesic effect, a significant advantage of the experimental group over the controls in this respect is worth noting (p=0.001 in favor of DN in all intergroup comparisons concerning results from the subjective assessment of pain (VAS). A statistically insignificant post-treatment improvement in balance and postural stability was noted in both groups, although the effects appeared to be short-term. Surprisingly, again, DN had no advantage over sham interventions. In both groups, all changes in the swing phase were statistically insignificant (p=0.201 for the dominant and p=0.283 for the non-dominant side) for the initial swing phase. In both groups, all changes in the stance phase were statistically insignificant (p=0.480 for the dominant and p=0.410 for the non-dominant side of the body). Conclusion: DN based on the FRSc appears promising as an effective adjunct to standard rehabilitation for LBP, showing improvements in functional performance and pain reduction.

Can Shockwave Treatment Elicit a Molecular Response to Enhance Clinical Outcomes in Pressure Ulcers? The SHOck Waves in wouNds Project.

Wound healing requires the coordinated interaction of dermis cells, the proper deposition of extracellular matrix, re-epithelialization, and angiogenesis. Extracorporeal shock wave (ESW) is a promising therapeutic modality for chronic wounds. This study determined the biological mechanisms activated under ESW, facilitating the healing of pressure ulcers (PUs). A group of 10 patients with PUs received two sessions of radial ESW (300 + 100 pulses, 2.5 bars, 0.15 mJ/mm2, 5 Hz). Histomorphological and immunocytochemical assessments were performed on tissue sections obtained from the wound edges before the ESW (M0) and after the first (M1) and second (M2) ESW. The proliferation index of keratinocytes and fibroblasts (Ki-67), the micro-vessels' density (CD31), and the number of myofibroblasts (α-SMA) were evaluated. The involvement of the yes-associated protein (YAP1) in sensing mechanical strain, and whether the nuclear localization of YAP1, was shown. The increased proliferative activity of epidermal cells and skin fibroblasts and the increased number of myofibroblasts, often visible as integrated cell bands, were also demonstrated as an effect of wound exposure to an ESW. The results indicate that the major skin cells, keratinocytes, and fibroblasts are mechanosensitive. They intensify proliferation and extracellular matrix remodeling in response to mechanical stress. A significant improvement in clinical wound parameters was also observed.

Ebbing Strength, Fading Power: Unveiling the Impact of Persistent Fatigue on Muscle Performance in COVID-19 Survivors.

The total number of confirmed cases of COVID-19 caused by SARS-CoV-2 virus infection is over 621 million. Post-COVID-19 syndrome, also known as long COVID or long-haul COVID, refers to a persistent condition where individuals experience symptoms and health issues after the acute phase of COVID-19. The aim of this study was to assess the strength and fatigue of skeletal muscles in people recovered from COVID-19. A total of 94 individuals took part in this cross-sectional study, with 45 participants (referred to as the Post-COVID Cohort, PCC) and 49 healthy age-matched volunteers (Healthy Control Cohort, HCC). This research article uses the direct dynamometry method to provide a detailed analysis of post-COVID survivors' strength and power characteristics. The Biodex System 4 Pro was utilized to evaluate muscle strength characteristics during the fatigue test. The fatigue work in extensors and flexors was significantly higher in the PCC. The PCC also showed significantly less power in both extensors and flexors compared to the HCC. In conclusion, this study provides compelling evidence of the impact of post-COVID-19 fatigue on muscle performance, highlighting the importance of considering these effects in the rehabilitation and care of individuals recovering from the virus. PCC achieved lower muscle strength values than HCC.

The Immediate Clinical Effects Following a Single Radial Shock Wave Therapy in Pressure Ulcers: A Preliminary Randomized Controlled Trial of The SHOWN Project.

Objective: Recent preliminary reports indicate that extracorporeal shock wave therapy (ESWT) might be useful for chronic wounds, especially venous leg ulcers and diabetic foot ulcers. However, there is limited evidence for the utility and safety of ESWT in pressure ulcers (PUs). Therefore, this randomized controlled trial (RCT) aimed to assess immediate planimetric and clinical effects following a single radial ESWT session in PUs. Approach: A group of 40 patients with PUs was randomly assigned into 2 groups: active ESWT (n = 20), which underwent a single treatment with radial ESWT (300 + 100 impulses/1 cm2, 2.5 bars, 0.15 mJ/mm2, and 5 Hz) and placebo ESWT (n = 20), which was exposed to sham-radial ESWT. All patients continued standard wound care procedures. The planimetric assessment and clinical outcomes using Wound Bed Score (WBS) and Bates-Jansen Wound Assessment Tool (BWAT) were assessed before (M0) and after ESWT sessions (M1). Results: There was a significant planimetric enhancement observed after active ESWT reported as a reduction in all metric parameters: wound area from 11.51 to 8.09 cm2 (p < 0.001), wound length from 4.97 to 4.41 cm (p < 0.001), and wound width from 3.15 to 2.49 cm (p < 0.0001). Also, there was a significant beneficial clinical improvement observed with a WBS as an increased score from 3.85 to 9.65 points (p < 0.001) and with the BWAT as a decreased score from 45.45 to 30.70 points (p < 0.001). In turn, a regression in the placebo ESWT group was observed in all studied outcomes. Innovation: This study is the first RCT to provide the positive and immediate clinical effects of radial ESWT in promoting the healing of PUs. Conclusion: This preliminary RCT showed that even a single session of ESWT is a promising and clinically effective modality in managing PUs. However, there is still limited data regarding the usefulness of ESWT in PUs, and further studies are in demand.

The effectiveness of dry needling in patients with chronic low back pain: a prospective, randomized, single-blinded study.

Dry needling (DN) is a standard procedure for treating musculoskeletal disorders. However, there are no clear recommendations for using DN in low back pain (LBP). Therefore, this study aimed to assess the effectiveness of the novel DN program for reducing pain intensity and improving functional efficiency in patients with chronic LBP. A group of 40 patients with chronic LBP due to the L5-S1 discopathy were eligible and randomized into experimental (n = 20) and control (n = 20) groups. The DN program was performed for the experimental group according to the Five Regulatory Systems (FRS) concept. The control group received sham therapy using placebo needles. DN sessions were performed twice a week for 4 weeks. A single needling application lasted 60 min. Both groups received standard treatment and physical exercise of LBP for 1 month. Subjective pain was measured by a visual analog scale (VAS), functional efficiency was assessed with the Oswestry Disability Index (ODI), and the lower spine range of motion was measured with the Schober test. There were significant differences in pain reduction (VAS) in both groups (p < 0.001). The strongest analgesic effect in the DN group yielded 6.45 points immediately after the therapy, 6.2 points after 1 month, and 6 points after 3 months. The DN group scored higher VAS reduction than the control group (p < 0.001). There were significant differences in the functional state (ODI) in the experimental group (p < 0.001). There was a significant ODI decrease by 18.1 points, after 1 month by 18.9 points, and after 3 months by 17.6 points. No significant differences were found in the control group (p > 0.05). Intergroup differences were observed in the functional efficiency in ODI in all measurement time-points (p < 0.001). There were significant differences in the range of motion (Schober test) in the DN group (main effect: p < 0.001). For all measurements, differences (p < 0.001) were observed in favor of DN compared to the control. In conclusion, DN program according to the FRS concept stands for the novel treatment method supplemented by an exercise program, effectively reducing pain and improving functional efficiency in LBP patients.

Efficacy of Focused Extracorporeal Shock Wave Therapy in Chronic Low Back Pain: A Prospective Randomized 3-Month Follow-Up Study.

BACKGROUND Extracorporeal shock wave therapy (ESWT) is a modern physiotherapeutic method that is useful for treating musculoskeletal conditions. There are still limited data from well-designed studies evaluating the clinical efficiency of ESWT in low back pain (LBP). Therefore, this study aimed to assess the effectiveness of the focused ESWT (fESWT) in reducing pain and improving the functional status of patients with chronic LBP. MATERIAL AND METHODS The study involved 40 patients with L5-S1 discopathy with chronic LBP pain who were randomized into 2 groups: group A (n=20, mean age of 42.3±13.1 years) and group B (n=20, mean age of 45.4±14 years). Group A was an experimental group treated with an fESWT at the lumbar and sacral spine (0.15 mJ/mm², 1000 pulses, 4 Hz). Group B was a control group, treated with a sham fESWT. The treatment protocol in both groups included identical stabilization training (45 minutes, once a day, 5 days a week). Study outcomes included subjective pain with a visual analog scale (VAS) and Laitinen Pain Scale (LPS), and functional status using the Oswestry Disability Index (ODI). Measurements were made before and after treatments, as well as follow-up observations at 1 and 3 months following ESWT. The study was prospectively registered at the ISRCTN registry platform (no. ISRCTN13785224). RESULTS There was a significant analgesic effect (VAS and LPS) in both groups; however, it was significantly greater in the experimental group compared to the sham group (P<0.05). A more significant decrease in the perceived pain (VAS and LPS) was observed immediately after the active fESWT therapy. In follow-up observations (after 1 and 3 months), there were no significant between-group differences (P>0.05). Also, there was a significant effect in terms of functional state (ODI) for both groups (P<0.05); however, between-group comparisons revealed no statistically significant differences (P>0.05). CONCLUSIONS Focused ESWT with an exercise program can be effective in patients with chronic LBP. ESWT allows reducing pain, although it does not seem to significantly improve a patient's functional state.

A Randomised-Controlled Clinical Study Examining the Effect of High-Intensity Laser Therapy (HILT) on the Management of Painful Calcaneal Spur with Plantar Fasciitis.

Calcaneal spur and plantar fasciitis are the most common causes of plantar heel pain. There are many effective physical modalities for treating this musculoskeletal disorder. So far, the are no clear recommendations confirming the clinical utility of high-intensity laser therapy (HILT) in the management of painful calcaneal spur with plantar fasciitis. This study aimed to evaluate the effectiveness of HILT in pain management in patients with calcaneal spur and plantar fasciitis. A group of 65 patients was assessed for eligibility based on the CONSORT guidelines. This study was prospectively registered in the Australian New Zealand Clinical Trial Registry platform (registration number ACTRN12618000744257, 3 May 2018). The main eligibility criteria were: cancer, pregnancy, electronic and metal implants, acute infections, impaired blood coagulation, cardiac arrhythmias, taking analgesic or anti-inflammatory medications, non-experience of heel pain, or presence of other painful foot conditions. Finally, 60 patients were randomly assigned into two groups: study group (n = 30, mean age 59.9 ± 10.1), treated with HILT (7 W, 149.9 J/cm2, 1064 nm, 4496 J, 12 min), and placebo-controlled group (n = 30, mean age 60.4 ± 11.9), treated with sham HILT therapy. Both groups received ultrasound treatments (0.8 W/cm2, 1 MHz frequency, 100% load factor, 5 min). Treatment procedures were performed once a day, five times per week for three weeks (total of 15 treatment sessions). Study outcomes focused on pain intensity and were assessed before (M1) and after (M2) the treatment as well as after 4 (M3) and 12 (M4) weeks using the Visual Analogue Scale (VAS) and the Laitinen Pain Scale (LPS). According to VAS, a statistically significant decrease in the study group was observed between M1 and M2 by 3.5 pts, M1 and M3 by 3.7 pts, and M1 and M4 by 3.2 pts (p < 0.001). On the other hand, the control group showed a statistically significant decrease (p < 0.001) between M1 and M2 by 3.0 pts, M1 and M3 by 3.4 pts, and M1 and M4 by 3.2 pts. According to LPS, a statistically significant decrease in the study group was observed between M1 and M2 by 3.9 pts, M1 and M3 by 4.2 pts, and M1 and M4 by 4.0 pts (p < 0.001). On the other hand, the control group showed a statistically significant decrease between M1 and M2 by 3.2 pts (p = 0.002), M1 and M3 by 4.0 pts (p < 0.001), and M1 and M4 by 3.9 pts (p < 0.001). However, there were no statistically significant differences between the groups in VAS and LPS (p > 0.05). In conclusion, the HILT does not appear to be more effective in pain management of patients with calcaneal spurs and plantar fasciitis than the conservative standard physiotherapeutic procedures.

The Current State of Knowledge on the Clinical and Methodological Aspects of Extracorporeal Shock Waves Therapy in the Management of Post-Stroke Spasticity-Overview of 20 Years of Experiences.

In many patients after stroke, spasticity develops over time, resulting in a decrease in the patient's independence, pain, worsening mood, and, consequently, lower quality of life. In the last ten years, a rich arsenal of physical agents to reduce muscle tone such as extracorporeal shock therapy (ESWT) wave has come through. The aim of this narrative review article is to present the current state of knowledge on the use of ESWT as a supplement to the comprehensive rehabilitation of people after stroke suffering from spasticity. The PubMed and PEDro databases were searched for papers published in English from January 2000 to December 2020, 22 of which met inclusion criteria for clinical studies related to post-stroke spasticity management with ESWT. A total of 22 studies including 468 post-stroke patients-11 reports with the upper limb (267 patients) and 10 reports within the lower limb (201 patients), as well as one report including both upper and lower limb. We focused our attention on clinical and methodological aspects. Therefore, we performed the assessment of enrolled studies in terms of methodological quality using the PEDro and level of evidence using the National Institute for Health and Clinical Excellence (NICE) guidelines. Furthermore, we indicated implications for clinical practice in using ESWT for post-stroke spasticity management. Moreover, we discussed a suggestion for future research directions. In conclusion, an ESWT effectively reduces muscle tone in people with spastic limb after stroke. Further, ESWT is safe and free of undesirable side effects. The mechanism of action of ESWT on muscles affected by spasticity is still unknown. To date, no standard parameters of ESWT in post-stroke spasticity regarding intensity, frequency, location, and the number of sessions has been established. Further research, meeting the highest standards, is needed to establish uniform muscle stimulation parameters using ESWT.

Muscle torque production and kinematic properties in post-stroke patients: a pilot cross-sectional study.

PURPOSE: Stroke-related hemiplegia is an important factor influencing parameters of gait. So far, limited papers have assessed temporo- spatial capabilities and their correlations with gait parameters in the early post-stroke stage. This pilot study evaluated the temporospatial parameters of gait and assessed the maximal isometric and isokinetic torque production of the plantar flexor and dorsiflexor muscles. METHODS: 15 patients with lower limb spasticity and 15 healthy controls were included. Stroke severity was assessed using the Modified Ashworth Scale and the Barthel Index. Gait cadence, gait speed, and gait cycle were assessed using inertial sensors during a Timed Up and Go test. Maximal isometric and isokinetic torque production of the ankle plantar flexor and dorsiflexor muscles were assessed using an isokinetic dynamometer device. RESULTS: Post-stroke patients had statistically significantly lower gait cadence than healthy participants (17%, p < 0.05). Statistically significantly lower values of vertical acceleration were also noted during a sit-to-stand movement task (42%, p < 0.05). Plantar flexion torque of the affected limb was significantly different during isometric (63%, p ≤ 0.01) and isokinetic work for 30o/s (49%, p = 0.04), 60o/s (58%, p = 0.01) and 20 °/s (53%, p = 0.01). Dorsiflexor muscles' torque production was significantly different in isometric activity (38%, p = 0.04). A statistically significant positive correlation occurred between the absolute peak torque of the dorsiflexor muscles in both static and speed phases of gait (Rs = 0.65, p = 0.04). CONCLUSIONS: Despite the low intensity of spasticity and early phase after stroke, differences in the muscle torque production and temporo-spatial parameters, as well as the correlations between them, were noticeable.

Evaluation of Postural Stability and Transverse Abdominal Muscle Activity in Overweight Post-Stroke Patients: A Prospective, Observational Study.

PURPOSE: Post-stroke hemiparesis has a significant impact on postural stability. The transversus abdominis (TrA) muscle contributes to the stability of the spine. The aim was to assess both the postural stability and the activity of the TrA muscle in overweight post-stroke patients. METHODS: A group of 56 participants (61.12 ± 11.5 years) was divided into the study group (n=28 post-stroke patients, 63.7 ± 10.9 years) and control group (n= 23 healthy participants (58.5 ± 12.2 years). The Berg Balance Scale (BBS) and the Timed Up and Go Test (TUG) were used to evaluate postural stability and risk of falls. The Pressure Bio-Feedback Stabilizer (PBFS) device was used to assess functional stability. RESULTS: Stroke had a significantly negative effect on the BBS (p < 0.001) and TUG (p = 0.001). The older age negatively affected the BBS (p = 0.001), TUG (p = 0.017), and the TrA muscle activity (p = 0.017). Higher values of body mass index (BMI) negatively affected the BBS (p = 0.028), however there were no changes of TUG results (p = 0.141), and the TrA muscle activity (p = 0.808). Also, BBS and TUG results were not associated with TrA muscle activity (p = 0.541 and p = 0.411, respectively). The results of the BBS, TUG, and PBFS did not differ according to gender (p < 0.05). Time from stroke negatively affected the TUG (p = 0.001), but had no effect on the TrA muscle activity (p < 0.05). The side of hemiparesis did not affect the postural stability (p < 0.05). CONCLUSION: The consequences of a stroke have an essential negative effect on postural stability. Factors such as age, gender, time from stroke, and the side of the hemiparesis have not negatively affected postural stability in overweight post-stroke patients.

Effect of Radial Extracorporeal Shock Wave Therapy on Pain Intensity, Functional Efficiency, and Postural Control Parameters in Patients with Chronic Low Back Pain: A Randomized Clinical Trial.

Low back pain (LBP) is the leading cause of disability worldwide, placing a significant economic burden on healthcare systems. Radial extracorporeal shock wave therapy (rESWT) is useful in the rehabilitation of orthopedic diseases; however, there is still limited evidence for patients with LBP. The aim of this study was to assess the effect of rESWT on pain level, functional efficiency, and parameters of postural control in patients with LBP. Participants were randomized into group A (n = 20) treated with rESWT and group B (n = 20) treated with sham rESWT (placebo). Both groups received conventional physiotherapy, including core stability exercises. The following tests were performed: the Laitinen Pain Scale (LPS), the Roland-Morris Questionnaire (RMQ), the original Schober Test (OST), and a stabilometric platform for the assessment of postural sway, including total sway path (TSP). We found that the analgesic effect was higher after rESWT, especially in the follow-up's (p < 0.05). Similar results were found for functional efficiency and range of motion (p < 0.05). The improved posture stability in placebo group B was not statistically significant (p > 0.05). The stabilometric parameters in group A were still gradually improved and statistically significant, even in follow-ups (p < 0.05). In conclusion, the rESWT had a significant effect on the reduction of pain and the improvement of functional condition compared to a conventional physiotherapy program. Also, rESWT with core stability exercises led to significant improvements in postural sway compared with conventional physiotherapy in patients with LBP.

Shock Waves as a Treatment Modality for Spasticity Reduction and Recovery Improvement in Post-Stroke Adults - Current Evidence and Qualitative Systematic Review.

PURPOSE: This systematic review examines intervention studies using extracorporeal shock wave therapy (ESWT) application in post-stroke muscle spasticity with particular emphasis on the comparison of two different types of radial (rESWT) and focused shock waves (fESWT). METHODS: PubMed, PEDro, Scopus, and EBSCOhost databases were systematically searched. Studies published between the years 2000 and 2019 in the impact factor journals and available in the English full-text version were eligible for inclusion. All qualified articles were classified in terms of their scientific reliability and methodological quality using the PEDro criteria. The PRISMA guidelines were followed and the registration on the PROSPERO database was done. RESULTS: A total of 17 articles were reviewed of a total sample of 303 patients (age: 57.87±10.45 years and duration of stroke: 40.49±25.63 months) who were treated with ESWT. Recent data confirm both a subjective (spasticity, pain, and functioning) and objective (range of motion, postural control, muscular endurance, muscle tone, and muscle elasticity) improvements for post-stroke spasticity. The mean difference showing clinical improvement was: ∆=34.45% of grade for fESWT and ∆=34.97% for rESWT that gives a slightly better effect of rESWT (∆=0.52%) for spasticity (p<0.05), and ∆=38.83% of angular degrees for fESWT and ∆=32.26% for rESWT that determines the more beneficial effect of fESWT (∆=6.57%) for range of motion (p<0.05), and ∆=18.32% for fESWT and ∆=22.27% for rESWT that gives a slightly better effect of rESWT (∆=3.95%) for alpha motor neuron excitability (p<0.05). The mean PEDro score was 4.70±2.5 points for fESWT and 5.71±2.21 points for rESWT, thus an overall quality of evidence grade of moderate ("fair" for fESWT and "good" for rESWT). Three studies in fESWT and four in rESWT obtained Sackett's grading system's highest Level 1 of evidence. CONCLUSION: The studies affirm the effectiveness of ESWT in reducing muscle spasticity and improving motor recovery after stroke.

Thermographic evaluation of experimental pleurisy induced by carrageenan and modified by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

PURPOSE: The use of a thermal imaging camera may improve the detection of changes during inflammation process propagation in animals and humans that could be caused by numerous factors like 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). METHODS: Rats were randomised and divided into two groups, C group, in which experimental pleural inflammatory reaction was evoked and TCDD group, in which a single dose was applied 21 days before administration of 1% carrageenan solution. Infrared thermograms were taken with a microbolometer thermal imaging camera MobIR M8. The surface temperature distribution was measured in three randomly selected animals. RESULTS: In the analysis of correlation we found negative results between both groups. In the C group, the pleurisy was developed and allowed to develop freely. It can be observed that both the average maximum temperature and the average minimum temperature were the highest after 48 hours after injection of the 1% carrageenan in solution. In TCDD group, lowered temperature in all days of experiments was noted. However, the increase of temperature after carrageenan injection was similar. The main changes observed in the lungs were oedema, hyperemia with clot formation and changes in lung structure. Several proliferative changes in the lungs were noted. Moreover, increased number of goblet cells as well and increased release of the surfactant was observed. The activation of fibroblasts and synthesis of collagen fibers was noted. CONCLUSIONS: The TCDD administration results in the reduction of superficial temperature, which is easily detectable by thermal imaging camera that can be effectively used in monitoring the course of inflammation.

The Effectiveness Of Radial Extracorporeal Shock Wave Therapy In Patients With Chronic Low Back Pain: A Prospective, Randomized, Single-Blinded Pilot Study.

PURPOSE: This prospective, randomized and single-blinded study assesses the influence of radial extracorporeal shock wave therapy (rESWT) in patients with low back pain (LBP). METHODS: A total of 52 patients with LBP were enrolled in the study, out of which a homogeneous group of 40 patients with mean age of 53.45±4.9 years was included. Patients were randomized into group A (n=20) treated with rESWT (2000 pulses; 2.5 bars; 5 Hz, 7 mins) performed twice a week for five weeks (10 sessions) and stabilization training, as well as group B (n=20) treated with sham rESWT and stabilization training. To analyze the therapeutic progress, the following tests were performed (before and after therapy; 1 and 3 months follow-up) to assess pain and functional efficiency: (1) Visual Analog Scale (VAS), (2) Laitinen Pain Scale (LPS), and (3) Oswestry Disability Index (ODI). RESULTS: The control group had a statistically significant advantage over the rESWT group (4.4 vs. 3.1 points on the VAS; p=0.039). However, in long-term observations, group A gradually experienced more pain relief than group B (2.7 vs. 3.5 points, p>0.05, at one month and 2.0 vs. 4.4 points at three months after treatment; p<0.0001). Similar findings can be seen in the analysis of changes in pain sensations measured with the LPS. The functional state (ODI) was better in rESWT group, especially in follow-up observation (9.3 vs. 14.6 points, p=0.033, at one month and 9.3 vs. 17.8 points, p=0.004, at three months after treatment). CONCLUSION: The rESWT combined with stabilization training is particularly effective in the long-term and achieves a stable beneficial effect for patients with LBP. The use of rESWT has a significant long-term influence on the reduction of pain and the improvement of the general functional state in relation to the conventional motor improvement program.

Immediate effects of the respiratory stimulation on ventilation parameters in ischemic stroke survivors: A randomized interventional study (CONSORT).

BACKGROUND: Post-stroke brain damage, which affects the central control of respiration, leads to various respiratory disorders. They can be caused by the weakening of the respiratory muscles and chest movements, which can indirectly contribute to an impairment of the ventilation function. The aim of the study is an objective assessment of the effect of a single-session intervention of respiratory stimulation through Proprioceptive Neuromuscular Facilitation (PNF) on chosen respiratory parameters and the following comparison of these changes with a group in which positioning was used (intra- and intergroup comparison). METHODS: This was a randomized interventional study evaluating the respiratory parameters depending on the applied respiratory stimulation in patients after ischemic stroke. The patients qualified to participate in the study were randomly assigned to 1 of 2 groups: PNF-treated group - in which respiratory stimulation through PNF was used, PNF untreated group - in which positioning was used. The research procedure consisted of several stages. First, an interview was conducted with each participant and basic data was collected. Then, spirometry was conducted, after which each patient underwent a single-session intervention according to their assigned group. Finally, the patients were given another spirometry examination. The main outcomes will be to compare the results of a spirometry test (FVC, FEV1, FEV1/ FVC%, PEF) before and after single-session intervention and between groups. RESULTS: Based on the inclusion and exclusion criteria for the study, 60 patients took part in the measurement. The values of FEV1/FVC% were higher in PNF-treated group than in PNF-untreated group, if the post-intervention measures (P = .04) are considered. The difference between the pre- and post-intervention results of the FEV1/FVC% values in PNF-untreated group was substantially lower than in PNF-treated group (P = .001). CONCLUSION: A single application of respiratory stimulation through PNF positively affect air flow in the respiratory tract. Application of PNF stimulation contributed to an increase in the FEV1/FVC% parameter. However, no positive changes were noted in the other parameters, which would provide proof of the beneficial effect of facilitation on the respiratory system function.

Proprioceptive Neuromuscular Facilitation for Accessory Respiratory Muscles Training in Patients After Ischemic Stroke.

This study focused on how pulmonary function is affected by proprioceptive neuromuscular facilitation (PNF) of accessory respiratory muscles in the chronic post-stroke phase. The study involved patients who had had ischemic stroke 6 months or more before the PNF treatment investigated. The objective was to define the effect of PNF on bioelectrical resting and maximum activity of the accessory muscles. Patients were randomly assigned to PNF treatment and just positioning treatment as a reference for comparison; 30 patients each. Electromyography of accessory muscles was investigated before and after physiotherapeutic treatments. We found that there was a greater reduction in EMG activity in all muscles investigated after PNF compared to positioning treatment alone. A reduction of muscle activity due to PNF concerned both affected and unaffected body side, but it was greater on the affected side. We conclude that a reduction of the accessory respiratory muscle activity due to PNF treatment could be of benefit in chronic stoke patients in that it would help normalize breathing pattern and thereby prevent the development of hypoxia.

Photobiomodulation using high- or low-level laser irradiations in patients with lumbar disc degenerative changes: disappointing outcomes and remarks.

BACKGROUND: Laser therapy seems to be a beneficial physical agent for chronic low back pain (LBP), and it is commonly used in the clinical rehabilitation practice. However, there are still no indisputable and clearly defined protocols and practical guidelines, and further, the methodology of the previous reports leaves many unsatisfied and raises some reservations. OBJECTIVE: The aim of this study was to evaluate the effectiveness of low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) in patients with lumbar disc degenerative changes based on the analysis of the short- and long-term results and in comparison with the placebo effect. DESIGN: This study was a prospective and placebo-controlled clinical trial. MATERIALS AND METHODS: A group of 68 participants were qualified for the therapy and were assigned to four comparative groups in the order they volunteered: HILT of 1,064 nm, 60 J/cm2, 10 minutes (HILT); sham (HILT placebo); LLLT of 785 nm, 8 J/cm2, 8 minutes; and sham (LLLT placebo). The following tests were used to assess the effectiveness of treatment: 1) the visual analogue scale; 2) the Laitinen Questionnaire Indicators of Pain; 3) the Oswestry Disability Index; 4) the Roland-Morris Disability Questionnaire; 5) Lasegue test; and 6) Schober's test. All measurements were carried out before and after irradiations (3 weeks) and in follow-ups (1 and 3 months). RESULTS: After applying verum or placebo laser irradiation, therapeutic progress was observed in all comparative groups; however, no statistically significant differences were observed among the procedures. CONCLUSION: The high- and low-energy laser therapy methods used in the present article are ineffective in relation to patients with lumbar disc degenerative changes in both the short- and long-term perspectives and do not show a significant advantage over the placebo effect.

Effect of laser therapy on expression of angio- and fibrogenic factors, and cytokine concentrations during the healing process of human pressure ulcers.

Objective: To evaluate the effect of laser irradiation at different wavelengths on the expression of selected growth factors and inflammatory mediators at particular stages of the wound healing process. Methods: Sixty-seven patients were recruited, treated, and analyzed (group A - 940 nm: 17 patients; group B - 808 nm: 18 patients; group C - 658 nm: 16 patients; group D - sham therapy: 17 patients). Patients received a basic treatment, including repositioning and mobilization, air pressure mattress and bed support surfaces, wound cleansing and drug therapy. Additionally, patients received laser therapy once a day, 5 times a week for 1 month in use of a semiconductor lasers (GaAlAs) which emitted a continuous radiation emission at separate wavelengths of 940 nm (group A), 808 nm (group B) and 658 nm (group C). In group D (sham therapy), laser therapy was applied in the same manner, but the device was off during each session (only the applicator was switched on to scan pressure ulcers using none coherent red visible light). Results: The positive changes in the measured serum (IL-2, IL-6 and TNF-α) and wound tissue (TNF-α, VEGF and TGFß1) parameters appeared to be connected only with the wavelength of 658 nm. The significant change in pro-inflammatory mediator levels [interleukin 2 (IL-2) with p=0.008 and interleukin 6 (IL-6) with p=0.016] was noticed after two weeks of laser therapy. In the other groups, the inflammation was also reduced, but the process was not as marked as in group C. Similarly, in the case of tumor necrosis factor (TNF-α) concentration, where after two weeks of treatment with irradiation at a wavelength of 658 nm, a rapid suppression was observed (p=0.001), whereas in the other groups, these results were much slower and not as obvious. Interestingly, again in the case of group C, the change in TNF-α concentration in wound tissue was most intensive (≈75% reduction), whereas the changes in other groups were not as obvious (≈50% reduction). After irradiation (658 nm), the VEGF expression increased significantly within the first two weeks, and then it decreased and maintained a stable level. In contrast, the TGFß1 activity remained level, but always higher in comparison to other groups Conclusions: The effective healing of pressure ulcers is connected with laser irradiation at a wavelength of 658 nm. We believe that this effect is related to the inhibition of inflammatory processes in the wound and stimulation of angiogenesis and fibroblast proliferation at this specific radiation (based both on concentration of interleukins and TNF-α serum level and VEGF, TGFß1, TNF-α activities in wound biopsies). Laser therapy at wavelengths of 940 and 808 nm does not significantly affect the above-mentioned repair processes, which explains its low effectiveness in the treatment of pressure ulcers.
