The Effect of Ankle Muscles Dry Needling on Brain Activity Map Based on fMRI: a Study Protocol for Randomized Controlled Trial.

Importance: Neuromodulation may be one of the underlying mechanisms of dry needling (DN); however, the mechanism has not yet been fully clarified. Objective: This randomized controlled trial is designed to evaluate DN stimulation of the tibialis anterior and peroneus longus muscles in chronic ankle instability (CAI) and healthy subjects, employing functional magnetic resonance imaging (fMRI). Design: Clinical study protocol, SPIRIT compliant. Setting: Brain Mapping Laboratory. Population: A total of thirty participants aged between 18 and 40 years old will be included in this study. Twenty healthy participants will be randomized into 2 groups (real DN and sham DN). Ten patients with CAI will also be recruited to the third group and receive only real DN for comparison. Exposures: Real and sham DN. Main Outcomes and Measures: The voxel count, coordinates of peak activation, and peak intensity will be obtained as primary outcomes to report brain map activation. Measurements will be taken before, during, and after DN treatment. The strength of the ankle dorsiflexors, active dorsiflexion range of motion, and McGill pain questionnaire short-form will be used as secondary outcome measures. Results: The results from this study will be published in peer-reviewed journals and disseminated as presentations at national and international congresses. Conclusion: This trial will explore brain responses to real and sham DN in healthy participants and to real DN in CAI patients. Overall, our results will provide preliminary evidence of the neural mechanism of DN.

Effects of dry needling on spasticity and motor function in paralympic athletes: a study protocol for a randomised controlled trial.

No study has evaluated the effects of dry needling on Paralympic athletes. Therefore, in this study, we will evaluate the effect of dry needling on lower limb spasticity and motor performance, as well as the range of motion of Paralympic athletes. The study will be a triple-blinded, randomised controlled trial. Twenty-four athletes aged 18-45 in T35-T38 groups of the International Paralympic Committee classification will be included in the study. Twelve participants will receive dry needling of the quadriceps and gastrocnemius muscles, and 12 will receive placebo treatment with sham needles at similar points. We will assess the spasticity of the quadriceps and gastrocnemius muscles using the Modified Ashworth Scale, evaluate motor function using the Selective Control Assessment of the Lower Extremity Scale and measure ankle range of motion (ROM) with a goniometer. Considering our hypothesis, the athletes who will undergo the dry needling are supposed to achieve better improvements in spasticity, ROM and motor performance. This study can provide useful information to help better decide on managing complications in Paralympics and its long-term outcomes, to cover the current lack in the literature.

The effects of local calf vibration on balance, blood flow, and nerve conductivity in patients with diabetic peripheral neuropathy: a pilot study.

OBJECTIVES: This study aimed to evaluate the effects of local calf vibration on balance, blood flow, and nerve conductivity in patients with diabetic peripheral neuropathy (DPN). METHODS: An open-label controlled trial was designed. Patients with confirmed diagnoses of type 2 diabetes and DPN were enrolled in the study and underwent ten sessions of local calf vibration therapy for the dominant leg. The other leg was considered the control. Balance evaluation, nerve conduction studies, and color Doppler ultrasound were performed before and after the treatment course. The Wilcoxon signed rank test and the Mann-Whitney test were used to evaluate the differences between the test results before and after the intervention and between the intervention and control legs. RESULTS: Seventeen patients with a mean age of 60.3 ± 5.6 years (11 males) participated in the study. Mean Brief BESTest total scores were significantly improved (14.06 vs. 17.35; P = .01, Cohen's d = 0.743). There were no significant differences between the treated and control legs regarding the nerve conduction and color Doppler ultrasound parameters before and after the intervention (P ≥ .054). Changes in the parameters were also not significantly different between legs (P ≥ .078), except for common peroneal nerve conduction velocity, for which there was a higher increase in its value in the treated legs compared to the control legs (4.17 vs. 0.9, P = .002). CONCLUSION: Local calf vibration may positively affect balance and lower extremities nerve conduction in patients with DPN, and the findings of this study can be a basis for studies evaluating the efficacy of local calf vibration for treating DPN.

Virtual reality games for rehabilitation of upper extremities in stroke patients.

INTRODUCTION: Stroke is one of the main causes of physical disability in which doing frequent and early exercise is imperative for rehabilitation. Virtual reality gaming has a high potential in rehabilitation leading to increased performance of patients. This study aimed to develop, validate and examine virtual reality games in chronic stroke patients. METHODS: This was a single before-after study. To determine the movements and content of games, 9 physiotherapists and 11 game designers were asked to participate in a questionnaire-based survey. Then, to evaluate the impact of games on rehabilitation, patients (N = 10; mean age = 52 ± 4.38) with chronic stroke were asked to play the games three times a week for four weeks. Outcomes included measurement of the ability to perform shoulder, elbow and wrist movements was performed using goniometric instrument, Modified Motor Assessment Scale (MMAS) was used to assess the functional ability of patients and muscle spasticity, and brunnstrom's stages of recovery test was also used to assess spastic and involuntary muscle movement. RESULTS: Games have positive effects on the horizontal abduction of shoulder (16.26 ± 23.94, P = 0.02), horizontal adduction of shoulder (59.24 ± 74.76, P = 0.00), supination of wrist (10.68 ± 53.52, P = 0.02), elbow flexion (0.1 ± 1.5, P = 0.00), and wrist flexion (0.06 ± 1.34, P = 0.03). However, they had no effects on the flexion of shoulder, flexion of elbow, extension of elbow, and extension of wrist (p-value> 0.05). CONCLUSIONS: The results showed that games improve the range of motion of the participants in terms of horizontal abduction and abduction of the shoulder, elbow flexion, and supination and flexion of the wrist. Due to the small sample size in this study, we recommend more studies with larger samples and a control group.

Effect of cycling and functional electrical stimulation with linear and interval patterns of timing on gait parameters in patients after stroke: a randomized clinical trial.

OBJECTIVE: Patients in the chronic phase after a stroke are an underrepresented group in the literature. Therefore, the aim of this study was to compare the effects of cycling and functional electrical stimulation with linear versus interval patterns of timing on gait parameters in patients after stroke. DESIGN: A double blinded, parallel, randomized clinical trial. SETTING: Neuroscience Institute. PARTICIPANTS: Patients with lower limb disability due to stroke (N = 30) with a stroke onset >6 months and <18 months. INTERVENTIONS: Twenty-eight minutes of leg cycling with functional electrical stimulation with linear or interval patterns of timing applied to the peroneal and biceps femoris muscles, 3 times/week for 4 weeks. MAIN MEASURES: Timed 10-Meter Walk Test and Functional Ambulation Classification were the primary outcome measures. The Modified Modified Ashworth scale, active range of motion, Timed Up and Go Test, and Single Leg Stance Test were the secondary outcome measures. Evaluation was performed at baseline, after 4, and after 8 weeks. RESULTS: Thirty participants completed the 4-week intervention (interval group, n = 16; linear group, n = 14). The Functional Ambulation Classification, Timed 10-Meter Walk Test, and the Timed Up and Go Test improved significantly in both groups. The Modified Modified Ashworth scale scores for quadriceps and plantar flexion statistically decreased after 4-weeks in the interval group. Significant group-by-time interaction was shown for Timed Up and Go Test (p = 0.003, np2=0.228), knee flexion active range of motion (p < 0.001, np2=0.256) and dorsiflexion active range of motion (p < 0.001, np2=0.359). Modified Modified Ashworth scale and active range of motion in both the ankle and knee improved significantly in the interval group. CONCLUSIONS: The functional electrical stimulation with cycling protocols improved the Functional Ambulation Classification, Timed 10-Meter Walk Test, active range of motion, Timed Up and Go Test, and Modified Modified Ashworth scale. An interval protocol of timing was more effective than the linear protocol in terms of spasticity and active range of motion.Implications for rehabilitationCycling + functional electrical stimulation training with an interval pattern of timing seems superior to cycling + functional electrical stimulation training with a linear pattern.Interval protocol has positive effects on spasticity and range of motion after 12 sessions in patients post stroke.Cycling + functional electrical stimulation improves functional mobility and speed in stroke survivors and the effects of this intervention lasted in follow-up assessment after one month.

Concurrent impact of bilateral multiple joint functional electrical stimulation and treadmill walking on gait and spasticity in post-stroke survivors: a pilot study.

Background: Stroke causes multi-joint gait deficits, so a major objective of post-stroke rehabilitation is to regain normal gait function. Design and Setting: A case series completed at a neuroscience institute. Aim: The aim of the study was to determine the concurrent impact of functional electrical stimulation (FES) during treadmill walking on gait speed, knee extensors spasticity and ankle plantar flexors spasticity in post-stroke survivors. Participants: Six post-stroke survivors with altered gait patterns and ankle plantar flexors spasticity (4 = male; age 56.8 ± 4.8 years; Body Mass Index (BMI) 26.2 ± 4.3; since onset of stroke: 30.8 ± 10.4 months; side of hemiplegia [L/R]: 3:3) were recruited. Intervention: Nine treatment sessions using FES bilaterally while walking on a treadmill. Main Outcome Measures: Primary outcome measures included the Modified Modified Ashworth Scale (MMAS), Timed Up and Go test (TUG), 10-m walking test, gait speed, and Functional ambulation category (FAC). Secondary outcome measures included the Step Length Test (SLT), and active range of motion (ROM) of the affected ankle and the knee. Measurements were taken at baseline (T0), at the end of last treatment (T1), and 1 month after the final treatment session (T2). Results: The TUG, 10-m walking test, gait speed, FAC, active ROM, and SLT all significantly improved following treatment (P< .05), while ankle plantar flexors spasticity (P = .135), and knee extensors spasticity (P = .368) did not show any significant decrease. Conclusions: A short duration of bilateral FES in conjugation with treadmill walking contributed to significant improvement in gait speed, functional mobility, functional ambulation, range of motion and step length in post-stroke survivors. In contrast, no significant decreases were identified in the spasticity of the ankle plantar flexors and knee extensors muscles.

The Effect of Dry Needling on Lower Limb Dysfunction in Poststroke Survivors.

BACKGROUND: Spasticity is one of the main complications in poststroke survivors leading to difficulties in walking and standing resulting in high levels of disability. OBJECTIVE: The aim of the study was to investigate the effects of deep dry needling on lower limb dysfunction in poststroke spastic patients. METHODS: A randomized clinical trial conducted in poststroke survivors who were assigned to one of 2 groups: Deep dry needling (intervention group) and sham dry needling (control group). The primary outcome measures were Modified Modified Ashworth Scale (MMAS) and functional tests (timed up and go test, 10-meter walk test). Secondary outcome measures were active ankle dorsiflexion range of motion (AROM), passive ankle dorsiflexion range of motion (PROM), single leg stance test, and Barthel index. All measurements were assessed at baseline (T0), immediately after the third session 1 week later (T1), and 1 month after the end of the intervention (T2). RESULTS: We recruited 24 patients (71% male; mean age 57 ± 10 years; 26.4 ± 1.8 kg•m-2; time since event: 25.2 ± 12.5 months). There were significant improvements in MMAS, timed up and go test, 10-meter walk test, Barthel scale, and PROM (P < .05) in the intervention group compared to controls across the time-points. There were no significant improvements in AROM assessments (P > .05). CONCLUSIONS: Deep dry needling decreases muscle spasticity and improves lower limb function and gait speed in poststroke survivors.

Effects of kinesiotape on pain, range of motion, and functional status in patients with osteoarthritis: a randomized controlled trial.

This study aimed to determine the effects of kinesiotape (KT) on pain, range of motion, and functional status in patients with osteoarthritis of the knee. In this randomized controlled trial, patients with knee osteoarthritis, based on American College of Rheumatology criteria, and Kellgren-Lawrence grade 2 or 3 criteria were selected. Visual analogue scale and active range of motion were the primary outcome measures. Timed Up and Go test and 6-min walk test, were the secondary outcome measures. Evaluation was performed at baseline (T0), after 1 hr (T1), and after 72 hr (T2). We recruited 27 patients with osteoarthritis (age, 57.33±8.72 years; 63% female; body mass index, 29.7±4.3 kg/m2) who were randomly assigned into KT or sham-KT groups. There was a significant group by time interaction for the visual analogue scale (P< 0.001, η 2=0.593), active range of motion (flexion) (P<0.001, η 2=0.492), active range of motion (extension) (P<0.001, η 2=0.351), 6-min walk test (P<0.001, η 2=0.568), and Timed Up and Go test (P=0.026, η 2=0.136). Between-group comparisons revealed significant differences between KT and sham-KT in visual analogue scale and Timed Up and Go test in T1 and T2 assessments, with changes in knee flexion (P<0.002) and extension active range of motion (P<0.010) and 6-min walk test (P<0.044) at 72-hr posttreatment. This study showed that, 1 hr of KT is an effective treatment for decreasing pain and improving active range of motion and physical function at a 72-hr follow-up in patients with osteoarthritis.

The effects of cycling with and without functional electrical stimulation on lower limb dysfunction in patients post-stroke: A systematic review with meta-analysis.

BACKGROUND: One of the leading causes of disability in the world with enormous economic burden is stroke. OBJECTIVE: To quantify the effectiveness of different protocols of cycling with/without functional electrical stimulation on functional mobility after stroke. METHODS: Multiple databases were searched till 2018. Data extraction was performed using a pre-determined data collection form. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS: A total of 14 trials satisfied eligibility criteria and were included. Cycling had a positive effect on the 6-meter walking test performance (SMD, 0.41; 95% CI, 0.11 -0.71; I2 = 0% ) compared with no or placebo intervention (control). Compared with control, cycling had a positive effect on 10-meter walking speed (SMD, 0.30; 95% CI, 0.05 -0.55; I2 = 0% ), and on balance based on the Berg score (SMD, 0.32; 95% CI, 0.06 -0.57; I2 = 49% ). Cycling with functional electrical stimulation had a positive effect on balance (SMD, 1.48; 95% CI, 0.99 -1.97; I2 = 91% ) compared with cycling alone. CONCLUSIONS: It appears that cycling has a positive effect on walking speed, walking ability and balance. Functional electrical stimulation combined with cycling has positive effects on balance beyond cycling alone.

Concurrent Effects of Dry Needling and Electrical Stimulation in the Management of Upper Extremity Hemiparesis.

Stroke is one of the leading causes of disability in western countries. A variety of rehabilitation programs for the treatment of patients after stroke have been proposed. We describe the outcomes of a 49-year-old female patient with a 5-year history of right upper extremity hemiparesis after stroke. Physical examination revealed a right wrist extensor strength grade of 1 according to the Medical Research Council Manual Muscle Testing scale, Stage 4 according to the Brunnstrom hand functional recovery, and Grade 1 in finger flexor and in wrist flexor according to the Modified Modified Ashworth Scale system of muscle spasticity. Magnetic resonance imaging taken immediately after the stroke was indicative of an abnormal signal in the left paraventricular and lentiform nucleus. After receiving a single session of dry needling and electrical stimulation, the patient had significant improvement including a strength grade of 3 for the right wrist extensor muscles, Stage 6 according to the Brunnstrom hand functional recovery, and Grade 0 in finger flexor and in wrist flexor according to the Modified Modified Ashworth Scale system of muscle spasticity. This case report found that dry needling combined with electrical stimulation may be effective in hand function recovery, wrist extensor muscles strength, and decreased wrist and finger spasticity.

The effect of exercise therapy, dry needling, and nonfunctional electrical stimulation on radicular pain: a case report.

A 43-year-old male, office worker with history of chronic radicular low back pain radiating into the left leg was admitted to a sports medicine research center, neuroscience institute. During the past year, he visited a physiotherapist and orthopedic experts. Magnetic resonance imaging revealed a protruded disc at L4-5 level. Additionally, electromyography indicated that there was bilateral moderate irritation at the L5-S1 root. We designed a management package including exercise therapy, dry needling, and nonfunctional electrical stimulation for four sessions. Outcomes included pain intensity, pain with lumbar flexion, with the numerical rating scale (NRS), visual analogue scale (VAS), and function measured with the Oswestry Disability Index before and after the intervention. After 4 treatment sessions, the patient reported a reduction in pain intensity from a 9 to 2 on the NRS and from 90 to 30 on the VAS. In addition, the patient was able to perform lumbar flexion fully without pain.

A pilot study into the effect of low-level laser therapy in patients with chronic rhinosinusitis.

Chronic rhinosinusitis (CRS) is a common inflammatory disease of the nose and paranasal sinuses that has a significant impact on patients' quality of life. No study has examined the effectiveness of applying low-level laser therapy (LLLT) locally over the sinuses in patients with CRS. The aim of this study was to evaluate the effect of LLLT in patients with CRS. Fifteen adult patients with CRS participated in this pilot pretest-posttest clinical study. Patients were treated with a 830-nm Ga-Al-As laser in continuous-wave mode at a power output of 30 mW and energy dose of 1 J. Laser irradiation was delivered on six points over each maxillary or frontal sinus with 33 sec irradiation for each point and a total treatment duration of 198 sec for each sinus. Patients were given LLLT three times per week for ten treatment sessions. Patients were asked to score their symptoms in accordance with a four-point scale (0-3), and a total symptom score (TSS) for each patient was calculated. Percentage improvement of TSS was considered as the primary outcome measure. TSS was calculated at baseline (T0), at 2 weeks (T1) and at 4 weeks (T2). The TSS was improved significantly at T1 (39%) and at T2 (46.34%). A large effect size for LLLT was found (ηp(2) ηp(2) = 0.63). The therapeutic effect was sustained for a mean of 5 months. This pilot study indicates that LLLT applied for 4 weeks improves symptoms in patients with CRS.
