The Combined Effect of Neuromuscular Electrical Stimulation and Insulin Therapy on Glycated Hemoglobin Concentrations, Lipid Profiles and Hemodynamic Parameters in Patients with Type-2-Diabetes and Hemiplegia Related to Ischemic Stroke: A Pilot Study.

Type-2-diabetes mellitus (T2DM) is a global problem of medical, social and economic consequences. Physical activity is a vital therapy in patients with T2DM, but some of them cannot exercise for various reasons. The purpose of our pilot study was to determine whether a combination of neuromuscular electrostimulation (NMES) and insulin therapy could improve the management of T2DM patients with hemiplegia caused by an ischemic stroke. Fifteen immobile patients with T2DM on insulin therapy were enrolled in the study. NMES was applied to their lower limbs for 60 min, 5 days a week, over a period of 12 weeks. The intervention caused statistically significant reductions in the blood concentrations of glycated hemoglobin, total cholesterol and low-density cholesterol in the participants. Furthermore, systolic and diastolic blood pressure levels were significantly lower. More randomized clinical trials are needed to accurately measure the effect of NMES on T2DM treatment and to determine whether it can be an alternative for physical activity for immobile patients with T2DM.

Pressure Injuries Treated With Anodal and Cathodal High-voltage Electrical Stimulation: the Effect on Blood Serum Concentration of Cytokines and Growth Factors in Patients With Neurological Injuries. A Randomized Clinical Study.

It remains unclear whether electrical currents can affect biological factors that determine chronic wound healing in humans. PURPOSE: The aim of this study was to determine whether anodal and cathodal high-voltage monophasic pulsed currents (HVMPC) provided to the area of a pressure injury (PI) change the blood level of cytokines (interleukin [IL]-1ß, IL-10, and tumor necrosis factor [TNF]-α) and growth factors (insulin-like growth factor [IGF]-1 and transforming growth factor [TGF]-ß1) in patients with neurological injuries and whether the level of circulatory cytokines and growth factors correlates with PI healing progression. METHODS: This study was part of a randomized clinical trial on the effects of HVMPC on PI healing. All patients with neurological injuries (spinal cord injury, ischemic stroke, and blunt trauma to the head) and a stage 2, stage 3, or stage 4 PI of at least 4 weeks' duration hospitalized in one rehabilitation center were eligible to participate if older than 18 years of age and willing to consent to donating blood samples. Exclusion criteria included local contraindications to electrical stimulation (cancer, electronic implants, osteomyelitis, tunneling, necrotic wounds), PIs requiring surgical intervention, patients with poorly controlled diabetes mellitus (HbA1C > 7%), critical wound infection, and/or allergies to standard wound treatment. Participants were randomly assigned to 1 of 3 groups: anodal (AG) or cathodal (CG) HVMPC treatment (154 µs; 100 Hz; 360 µC/sec; 1.08 C/day) or a placebo (PG, sham) applied for 50 minutes a day, 5 days per week, for 8 weeks. TNF-α, IL-1ß, IL-10, TGF-ß1, and IGF-1 levels in blood serum were assessed using the immunoenzyme method (ELISA) and by chemiluminescence, respectively, at baseline and week 4. Wound surface area measurements were obtained at baseline and week 4 and analyzed using a digitizer connected to a personal computer. Statistical analyses were performed using the maximum-likelihood chi-squared test, the analysis of variance Kruskal-Wallis test, the Kruskal-Wallis post-hoc test, and Spearman's rank order correlation; the level of significance was set at P ≤.05. RESULTS: Among the 43 participants, 15 were randomized to AG (mean age 53.87 ± 13.30 years), 13 to CG (mean age 51.08 ± 20.43 years), and 15 to PG treatment (mean age 51.20 ± 14.47 years). Most PIs were located in the sacral region (12, 74.42%) and were stage 3 (11, 67.44%). Wound surface area baseline size ranged from 1.00 cm2 to 58.04 cm2. At baseline, none of the variables were significantly different. After 4 weeks, the concentration of IL-10 decreased in all groups (AG: 9.8%, CG: 38.54%, PG: 27.42%), but the decrease was smaller in the AG than CG group (P = .0046). The ratio of pro-inflammatory IL-10 to anti-inflammatory TNF-α increased 27.29% in the AG and decreased 26.79% in the CG and 18.56% in the PG groups. Differences between AG and CG and AG and PG were significant (AG compared to CG, P = .0009; AG compared to PG, P = .0054). Other percentage changes in cytokine and growth factor concentration were not statistically significant between groups. In the AG, the decrease of TNF-α and IL-1ß concentrations correlated positively with the decrease of PI size (P <.05). CONCLUSION: Anodal HVMPC elevates IL-10/TNF-α in blood serum. The decrease of TNF-α and IL-1ß concentrations in blood serum correlates with a decrease of PI wound area. More research is needed to determine whether the changes induced by anodal HVMPC improve PI healing and to determine whether and how different electrical currents affect the activity of biological agents responsible for specific wound healing phases, both within wounds and in patients' blood. In clinical practice, anodal HVMPC should be used to increase the ratio of anti-inflammatory IL-10 to pro-inflammatory TNF-α , which may promote healing.

Extracorporeal Shock Wave Therapy for Achilles Tendinopathy.

Extracorporeal shock wave therapy (ESWT) is among the conservative treatments for Achilles tendinopathy. Unfortunately, no optimal application parameters have been determined that would ensure ESWT effectiveness in this condition. The aim of the paper is to use research reports on ESWT in patients with Achilles tendinopathy to help practising physiotherapists establish the most effective intervention parameters. A search was conducted using the following databases: PubMed, Scopus, EBSCOhost, and Web of Science. The papers were checked for relevant content and were included based on the following criteria: full-text article published in English and including comprehensive description of shock wave application. Twenty-two articles met the inclusion criteria. Most studies on the effectiveness of ESWT for Achilles tendinopathy included in this narrative review were randomized controlled trials. Two case-control studies, a case series study, prospective audit, clinical trial protocol, and a pilot study were also considered. The majority were prospective studies. Only a few authors presented the findings from retrospective observations. The two modalities of shock wave therapy used for Achilles tendinopathy are focused shock waves and radial shock waves. The literature contains reports presenting mainly beneficial effects of ESWT in patients with Achilles tendinopathy.

A Randomized, Controlled Clinical Study to Assess the Effect of Anodal and Cathodal Electrical Stimulation on Periwound Skin Blood Flow and Pressure Ulcer Size Reduction in Persons with Neurological Injuries.

The use of electrical stimulation (ES) should be considered for treating nonhealing pressure ulcers (PUs), but optimal ES wound treatment protocols have yet to be established. A randomized, controlled, double-blind clinical study was conducted to evaluate the effects of cathodal and anodal high-voltage monophasic pulsed current (HVMPC) on periwound skin blood flow (PSBF) and size reduction of Stage 2 to Stage 4 PUs of at least 4 weeks' duration. Persons >18 years of age, hospitalized with neurological injuries, at high risk for PU development (Norton scale <14 points; Waterlow scale >15 points), and with at least 1 Stage 2 to Stage 4 PU were eligible to participate in the study. Persons with necrotic wounds, osteomyelitis, electronic or metal implants in the PU area, PUs in need of surgical intervention, acute wound inflammation, diabetes (HBA1c >7%), diabetic neuropathy, cancer, and/or allergies to standard wound treatments were excluded. Patients were randomly assigned to 1 of 3 groups: anodal (AG), cathodal (CG), or placebo (PG) ES. All groups received individualized PU prevention and standard wound care. In the PG, sham ES was applied; the AG and CG were treated with anodal and cathodal HVMPC, respectively (154 µs 100 Hz; 360 µC/second; 1.08 C/day), 50 minutes per day, 5 days per week, for a maximum of 8 weeks. PSBF was measured using laser Doppler flowmetry at baseline, week 2, and week 4, and wound surface area measurements were obtained and analyzed using a digitizer connected to a personal computer. Data analysis utilized the maximum-likelihood chi-squared test, the analysis of variance Kruskal-Wallis test, the Kruskal-Wallis post-hoc test, and Spearman's rank order correlation. Nonlinear approximation based on exponential function was used to calculate treatment time needed to reduce the wound area by 50%. In all tests, the level of significance was set at P ≤.05. Of the 61 participating patients, 20 were in the AG (mean age 53.2 ± 13.82 years), 21 in the CG (mean age 55.67 ± 17.83 years), and 20 in the PG (mean age 52.5 ± 13.18 years). PUs (baseline size range 1.01 cm2 to 59.57 cm2; duration 4 to 48 weeks) were most frequently located in the sacral region (73.77%) and classified as Stage 3 (62.29%). PSBF at week 2 was significantly higher in the AG and CG than in the PG (P <.05). Week 4 differences were not statistically significant. Wound percentage area reduction calculated at week 8 for the AG (64.10% ± 29.22%) and CG (74.06% ± 23.23%) were significantly different from PG ulcers (41.42% ± 27.88%; P = .0391 and P = .0024, respectively). In both ES groups, PSBF at week 4 and percent wound surface area reductions between weeks 4 and 8 were positively correlated, but only the AG correlation was statistically significant (P = .049). In this study, both ES modalities improved blood flow and wound area reduction rate. Studies examining optimal ES treatment times for healing to occur, the effect of comorbidities and baseline wound variables on ES outcomes, and the nature of the relationship between blood flow and healing are necessary.

Exercise-Based Cardiac Rehabilitation with and Without Neuromuscular Electrical Stimulation and its Effect on Exercise Tolerance and Life Quality of Persons with Chronic Heart Failure.

The study compares the effect of an exercise-based cardiac rehabilitation program with a program combining physical exercise and lower extremity neuromuscular electrical stimulation (NMES) on the recovery of patients with chronic heart failure (CHF) with NYHA II-III symptoms. Seventy two patients with stable CHF were randomly distributed to four groups that received exercise-based cardiac rehabilitation and pharmacological treatment. Groups I and II were additionally administered NMES (35 Hz and 10 Hz, respectively) and in Group III sham NMES was applied. Group IV (controls) received solely pharmacological and exercise treatment. Exercise tolerance and quality of life were assessed in patients pre-treatment and at week 3. Three weeks of rehabilitation induced significant increases (p < 0.05) in the distance covered in the 6-minute walk test, the metabolic equivalent (MET), the duration of the treadmill exercise stress test, the left ventricle ejection fraction (LVEF) and improved quality of life in all groups, but between-group differences were not significant (p > 0.05). In none of the groups were the left ventricle end-systolic and end-diastolic diameters (mm) measured at week 3 significantly different from their baseline values (p > 0.05). Exercise-based cardiac rehabilitation contributed to higher exercise tolerance, LVEF and quality of life of CHF patients (NYHA II-III), contrary to cardiac rehabilitation combined with lower extremity NMES (35 Hz and 10 Hz) that failed to induce such improvements. More research is necessary to assess the therapeutic efficacy of NMES applied to CHF patients with NYHA IV symptoms.

The Efficacy of Pressure Ulcer Treatment With Cathodal and Cathodal-Anodal High-Voltage Monophasic Pulsed Current: A Prospective, Randomized, Controlled Clinical Trial.

BACKGROUND: Studies show that anode and cathode electrical stimulation (ES) promotes the healing of wounds, but specific protocols for both electrodes are not available. OBJECTIVE: To compare the effectiveness of cathodal versus cathodal+anodal ES in the treatment of Category II-IV pressure ulcers (PrUs). DESIGN: Prospective, randomized, controlled, clinical study. SETTING: Three nursing and care centers. PATIENTS: Sixty-three participants with PrUs were randomly formed into a cathodal ES group (CG: N = 23; mean age of 79.35; SD 8.48), a cathodal+anodal ES group (CAG: N = 20; mean age of 79.65; SD 11.44) and a placebo ES group (PG: N = 20; mean age of 76.75; SD 12.24). INTERVENTION: All patients were treated with standard wound care and high-voltage monophasic pulsed current (HVMPC; twin-peak impulses; 154 µs; 100 pps; 0.25 A; 250 µC/s) for 50 minutes per day, 5 times a week, for 6 weeks. The CG, CAG, and PG received, respectively, cathodal, cathodal+anodal, and sham ES through electrodes placed on a moist gauze pad. The treatment electrode was placed on the wound, and the return electrode was positioned on healthy skin at least 20 cm from the PrU. MEASUREMENTS: Measurements were made at baseline, and after each of the 6 weeks of treatment. Primary outcome was percentage wound surface area reduction at week 6. RESULTS: Wound surface area decreased in the CG by 82.34% (95% confidence interval [CI] 70.06-94.63) and in the CAG by 70.77% (95% CI 53.51-88.04). These reductions were significantly greater than in the PG (40.53%; 95% CI 23.60-57.46). The CG and CAG were not statistically significantly different regarding treatment results. LIMITATIONS: The time of treatment proved insufficient for PrUs to close. CONCLUSIONS: Cathodal and cathodal+anodal HVMPC similarly reduced the area of Category II-IV PrUs.

Evaluation of the Effects of Neuromuscular Electrical Stimulation of The Lower Limbs Combined with Pulmonary Rehabilitation on Exercise Tolerance in Patients with Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease (COPD) is a systemic disease with multiple extrapulmonary manifestations including impeded skeletal muscle function, leading to decreased muscular strength and endurance in patients with COPD. Pulmonary rehabilitation eases the symptoms of the condition and produces increased muscular endurance. Neuromuscular electrical stimulation (NMES) may serve as a treatment alternative to traditional pulmonary rehabilitation. The aim of the study was to assess the effects of NMES combined with pulmonary rehabilitation on exercise tolerance in patients in comparison with pulmonary rehabilitation alone. The subjects included 30 patients with COPD randomly assigned to one of the two groups. The first group consisted of 15 patients who were treated with neuromuscular electrical stimulation at frequency of 35Hz and pulmonary rehabilitation (NMES+RP). The second group comprised 15 patients treated with pulmonary rehabilitation only (RP). Pre- and poststudy assessments were performed. The retrospective evaluation including an exercise tolerance test (i.e. six minute walk test (6MWT)), spirometry and blood gasometry was carried out after 3 weeks. Twenty-eight patients in total completed the study. In the NMES+RP group, an increase in exercise tolerance manifested by a longer distance walked in the 6MWT was observed in comparison to the pulmonary rehabilitation group. No effects of NMES combined with pulmonary rehabilitation on selected spirometric and gasometric parameters in patients with COPD were observed in comparison with traditional pulmonary rehabilitation. The acquired results suggest that NMES of the lower limbs may be applied as an additional form of pulmonary rehabilitation in patients with COPD.

Evaluation of the Healing Progress of Pressure Ulcers Treated with Cathodal High-Voltage Monophasic Pulsed Current: Results of a Prospective, Double-blind, Randomized Clinical Trial.

OBJECTIVE: To investigate the effectiveness of high-voltage monophasic pulsed current (HVMPC) as an adjunct to a standard wound care for the treatment of Stage II and III pressure ulcers (PrUs). DESIGN: Prospective, randomized, double-blind, controlled clinical study. SETTING: Two nursing and care centers. PATIENTS: Patients with PrUs that did not respond to previous treatment for at least 4 weeks were randomly assigned to the electrical stimulation (ES) group (25 patients; mean age of 79.92 ± 8.50 years; mean wound surface area [WSA] of 10.58 ± 10.57 cm) or to the control group (24 patients; mean age of 76.33 ± 12.74 years; mean WSA of 9.71 ± 6.70 cm). INTERVENTIONS: Both the ES and control groups received standard wound care and respectively, cathodal HVMPC (154 microseconds; 100 pulses per second; 0.24 A; 250 µ/s) applied continuously for 50 minutes once a day, 5 times a week, or sham HVMPC. MAIN OUTCOME: Percentage area reduction over 6 weeks of intervention. MAIN RESULTS: In the ES group, there was a statistically significant decrease in WSA after 1 week of treatment (35% ± 30.5%) compared with 17.07% ± 34.13% in the control group (P = .032). After treatment, at week 6, percentage area reduction in the ES group was 80.31% ± 29.02% versus 54.65% ± 42.65% in the control group (P = .046). CONCLUSIONS: Cathodal HVMPC reduces the WSA of Stage II and III PrUs. The results are consistent with the results of other researchers who used HVMPC to treat PrUs.

[Quality of life and physical activity of patients with inflammatory bowel diseases]. / Aktywnosc fizyczna i jakosc zycia pacjentów z nieswoistymi zapaleniami jelit.

AIM OF THE STUDY: Estimation of the quality of life of patients with inflammatory bowel diseases and comparison these results with control group. MATERIAL AND METHODS: A group of 16 patients with inflammatory bowel diseases and 13 healthy persons as a control group. In orderto estimate the quality of life, polish version of Inflammatory Bowel Disease Questionnaire (IBDQ) was used. The Second questionnaire that was used is WHOQOL-BREF (The World Health Organization Quality of Life). To assess the level of physical activity was applied the Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ). All the results have been correlated to answer the question if there is any relationship between the quality of life and physical activity and if level of these parameters is different in control group. RESULTS: In the group of patients the lowest level of functioning were stated on bowel ailments field and emotional field. The most important roles in patients life are social relationship and sanity. The higher level of the caloric consumption was stated in the group of patients with inflammatory bowel diseases in comparison to control group. There was no significant difference in caloric consumption related with the recreation and house works. Because of the fact that all of the patients were in the remission period, it was impossible to verify if there is any relationship between quality of life and the stage of disease. CONCLUSIONS: The results of researches have not proved relationship between the level of physical activity and the quality of life among the patients as well as in the control group.

The effects of mirror therapy on arm and hand function in subacute stroke in patients.

The aim of this study was to evaluate the effect of mirror therapy on arm and hand function in subacute stroke in patients. The study included 60 hemiparetic right-handed patients after ischemic stroke 8-10 weeks after onset. They underwent stationary comprehensive rehabilitation in the rehabilitation centre. They were divided into two randomly assigned groups: mirror (n=30) and control (n=30). For both groups, two subgroups were created: one that included patients with right arm paresis (n=15) and the other that included patients with left arm paresis (n=15). The mirror group received an additional intervention: training with a mirror for 5 days/week, 2 sessions/day, for 21 days. Each single session lasted for 15 min. The control group (n=30) underwent a conventional rehabilitation program without mirror therapy. To evaluate self-care in performing activities of daily living, the Functional Index 'Repty' was used. To evaluate hand and arm function, the Frenchay Arm Test and the Motor Status Score were used. Measurements were performed twice: before and after 21 days of applied rehabilitation. No significant improvement in hand and arm function in both subgroups in Frenchay Arm Test and Motor Status Score scales was observed. However, there was a significant improvement in self-care of activities of daily living in the right arm paresis subgroup in the mirror group measured using the Functional Index 'Repty'. Mirror therapy improves self-care of activities of daily living for patients with right arm paresis after stroke.

Using high-voltage electrical stimulation in the treatment of recalcitrant pressure ulcers: results of a randomized, controlled clinical study .

 The use of electrical stimulation has been studied in a variety of wounds emphasizing different variables with regard to provision of therapy. The purpose of this prospective, randomized, controlled clinical study was to evaluate the effect of high-voltage electrical stimulation (HVES) on nonhealing, lower-extremity, Stage II and Stage III pressure ulcers. Patients admitted for care and eligible to participate in the study received standard supportive care and topical treatments covered with wet-to-moist dressings. Patients assigned to the treatment arm of the study also received HVES (100 V; 100 µs; 100 Hz) continuously for 50 minutes once daily, five times per week. Patients were followed until healing for a maximum of 6 weeks. Wound tracings and measurements were obtained weekly. Over a 4-year period, 26 patients were enrolled in the treatment and 24 in the control group. Ulcers had existed for an average of 3.17 and 2.83 months in the treatment and control groups, respectively. Most were classified as Stage II (17 in the treatment and 16 in the control group) with an average baseline size of 4.54 cm2 and 3.97 cm2, respectively. Wound areas and linear measurements decreased significantly in both groups (P <0.05), but increases in granulation tissue were significant in the treatment group only (P = 0.006). Wound area, linear measurement, wound volume, and granulation tissue changes were statistically significantly greater in the treatment than in the control group starting in the second week of treatment. Week 6 surface area change was 88.9% (SD 14) in the treatment and 44.4% (SD 63.1) in the control group (P = 0.00003). Correlation coefficients between changes in wound surface area, longest length, and longest width were R = 0.96 and R = 0.98 in the treatment and R = 0.94 and R = 0.89 in the control group. HVES improved the healing rate of recalcitrant Stage II and Stage III pressure ulcers. Research to compare the effectiveness of using cathodic and anodal stimulation combined or alone and to determine the optimal duration of these two types of electrical stimulation is warranted.

Paffenbarger Physical Activity Questionnaire as an additional tool in clinical assessment of patients with coronary artery disease treated with angioplasty.

BACKGROUND: The association between frequency, intensity and duration of physical activity and the risk of cardiovascular disease has been investigated in several studies. Out of many methods used for assessment of physical activity, a questionnaire seems to be a simple and affordable method of assessing the risk of coronary artery disease (CAD). However, the number of clinical studies investigating the usefulness of physical activity questionnaires is limited. AIM: To analyse the usefulness of Paffenbarger Physical Activity Questionnaire (PPAQ) in assessment of the correlation between the magnitude of physical activity-related energy expenditure and physical capacity assessed with treadmill exercise test (ET), risk of early onset of major adverse cardiovascular events (MACE) and selected haemodynamic parameters in patients with CAD. METHODS: The study group consisted of 211 patients aged 34-79 years (mean 59) with CAD, with or without previous myocardial infarction (MI). All patients were surveyed using PPAQ at the time of PCI and then 6 months later together with ET and echocardiography. RESULTS: There was a significant correlation between the value of activity-related weekly energy expenditure assessed with the PPAQ and selected parameters of ET (duration: r = 0.2966, p < 0.0001; METs: r = 0.2221, p < 0.001; VO(2)max: r = 0.3075, p < 0.0001; resting HR: r = 0.1615, p < 0.01 and maximal HR: r = -0.1475, p < 0.01) and echocardiography (LVESD r = 0.2346, p < 0.0001). After the PCI procedure, there was a considerable increase in physical capacity (ET duration: 5.82 vs. 7.48 min, p < 0.0001; MET: 7.57 vs. 9.18, p < 0.0001; VO(2)max: 29.23 vs. 34.79 ml, p < 0.0001; HRmax: 123 vs. 132 beats/min, p < 0.0001) and LV function (EF% 51.64 vs. 52.45%, p < 0.01). There was an insignificant change in total physical activity-related energy expenditure of low intensity (< 4 MET), not exceeding 2000 kcal/week (from 3120.13 to 3139.18 kcal/week, p > 0.05). Thirty-seven patients with MACE had a trend towards a lower value of average weekly energy expenditure than the remaining 174 patients (2690.71 vs. 3206.06 kcal/week, NS). CONCLUSIONS: High values of correlation coefficients between the questionnaire results and some variables of ET and echocardiography examination make the PPAQ a useful tool in clinical studies.
