Effects of ankle joint mobilization with movement and weight-bearing exercise on knee strength, ankle range of motion, and gait velocity in patients with stroke: a pilot study

Awakening the control of the ankle dorsiflexors in the post-stroke hemiplegic subject to improve walking activity and social participation: the WAKE (Walking Ankle isoKinetic Exercise) randomised, controlled trial

Background

Stroke is the leading cause of acquired disability in France. While 90% of patients recover the ability to walk, it is often limited with a steady speed of approximately 0.7 m/s. This limitation of walking activity is partly related to a decrease in strength associated with more or less significant spasticity. In particular, it seems that the strength of the dorsiflexor muscles is directly related to walking speed. We hypothesise that a protocol based on gestural repetition targeted at the ankle during the subacute phase potentiates the recovery of motor control, improving walking activity, and participates in recovering better social participation.

Methods

An estimated total of 60 patients with subacute stroke will be recruited to participate in this multicentre, interventional, prospective, randomised controlled trial.

All participants will benefit from conventional rehabilitation. In addition, the experimental group will take part in an ankle isokinetic rehabilitation programme for 6 weeks (at least 25 sessions). The control group will receive the same duration of conventional rehabilitation.

The primary outcome measure will be a 10-m walking speed at post-intervention. Secondary outcomes will include social participation, walking spatio-temporal parameters, and dorsiflexor strength. Outcome measurements will be taken at baseline, immediately after treatment (6 weeks), then at 6 months and 1 year of follow-up.

Discussion

This study aims to provide scientific evidence that a protocol based on an early over-solicitation of the ankle dorsiflexor muscles to promote their “awakening” can serve to achieve a more effective walking activity, which in turn encourages social participation following discharge from the hospital.

This protocol should also help optimise physical medicine and rehabilitation practices: the more systematic use of the isokinetic dynamometer as a technique associated with, and integrated into the conventional rehabilitation protocol would allow an objective evaluation of the rehabilitation benefits and should increase the rehabilitation gain in central nervous system disorders.

Effects of Subtalar Joint Mobilization with Movement on Muscle Strength, Balance, Functional Performance, and Gait Parameters in Patients with Chronic Stroke: A Single-Blind Randomized Controlled Study

BACKGROUND

Losses in muscle strength, balance, and gait are common in patients with chronic stroke (CS). Ankle joint movements play a key role in this population to maintain a sufficient level of functional activity. The aim of this study was to investigate the effects of the subtalar joint (STJ) mobilization with movement (MWM) technique on muscle strength, balance, functional performance, and gait speed (GS) in patients with CS.

METHODS

Twenty-eight patients with CS were randomly divided into the control group (n = 14) and the STJ MWM group (n = 14). A 30-min neurodevelopmental treatment program and talocrural joint MWM were applied to both groups. Also, STJ MWM was applied to the STJ MWM group. The patients were treated 3 days a week for 4 weeks. Ankle dorsiflexion and plantarflexion muscle strength, Berg Balance Scale, Timed Up and Go test, and GS were evaluated before and after treatment.

RESULTS

Berg Balance Scale and Timed Up and Go test scores, dorsiflexion and plantarflexion muscle strength, and GS improved in both groups after the treatment sessions (P < .05), but the improvements were greater in the STJ MWM group compared with the control group (P < .05).

CONCLUSIONS

According to these results, STJ MWM together with neurodevelopmental treatment and talocrural joint MWM can increase ankle muscle strength, balance, functional performance, and GS on the affected leg in patients with CS.

Immediate Effect of Lower-Leg Kinesio Taping on Ankle Dorsiflexion and Gait Parameters in Chronic Stroke with Foot Drop

OBJECTIVE

Kinesio taping (KT) and proprioceptive neuromuscular facilitation (PNF) are interventions mainly used in clinical settings to improve gait after stroke. Lower-leg KT using the concept of PNF (PNF-KT) has been shown to enhance the recovery of gait speed in patients with stroke. But, the effect of PNF-KT on the ankle movement and gait parameters in stroke patients is unclear. We aimed to investigate the immediate effects of PNF-KT on ankle dorsiflexion range of motion (DF-ROM) and gait parameters in patients with stroke with foot drop.

MATERIALS AND METHODS

For the A-KT condition, tape was attached to the gastrocnemius and tibialis anterior muscles, and tape for eversion was attached. In the PNF-KT condition, tape was attached to the tibialis anterior, extensor hallucis and digitorum muscles. Ankle movement was measured as the ankle DF-ROM using an iSEN system. Gait ability was assessed using the GAITRite system. The measured gait variables were gait velocity, cadence, and step length (both sides).

RESULTS

A-KT and PNF-KT significantly improved the ankle DF-ROM, gait velocity, cadence, and the affected- and unaffected-side step length compared to that with no taping. Moreover, PNF-KT significantly increased the ankle DF-ROM, gait velocity, cadence, and the affected- and unaffected-side step length compared to that with A-KT.

CONCLUSIONS

PNF-KT applied to the affect side improved ankle DF-ROM and gait parameters in hemiplegic stroke patients than no taping, A-KT. Lower-leg PNF-KT may be a useful intervention in a rehabilitation program to improve ankle DF-ROM and gait parameters in chronic stroke patients with foot drop in clinical settings.

Proprioceptive Neuromuscular Facilitation Kinesio Taping Improves Range of Motion of Ankle Dorsiflexion and Balance Ability in Chronic Stroke Patients

This study aimed to determine the effect of a proprioceptive neuromuscular facilitation (PNF) pattern Kinesio taping (KT) application on the ankle dorsiflexion range of motion (DF-ROM) and balance ability in patients with chronic stroke. This crossover study included 18 patients with stroke. The subjects were randomly assigned to three interventions: barefoot, ankle KT (A-KT), and PNF-KT. The A-KT was applied to the gastrocnemius and tibialis anterior (TA) muscles, and subtalar eversion. The PNF-KT was applied on the extensor hallucis, extensor digitorum, and TA muscles. DR-ROM was measured using the iSen™, a wearable sensor. Balance ability was assessed based on static balance, measured by the Biodex Balance System (BBS), and dynamic balance, measured by the timed up and go (TUG) test and dynamic gait index (DGI). Compared with the barefoot and A-KT interventions, PNF-KT showed significant improvements in the ankle DF-ROM and BBS scores, TUG, and DGI. PNF-KT, for functional muscle synergy, improved the ankle DF-ROM and balance ability in patients with chronic stroke. Therefore, the application of PNF-KT may be a feasible therapeutic method for improving ankle movement and balance in patients with chronic stroke. Additional research is recommended to identify the long-term effects of the PNF-KT.

Effect of Ankle Joint Mobilization with Movement on Range of Motion, Balance and Gait Function in Chronic Stroke Survivors: Systematic Review of Randomized Controlled Trials

Background

Ankle joint mobilization with movement has been speculated to be an important intervention for enhancing range of motion, balance, and gait functions in chronic stroke survivors. Nonetheless, there is a scarcity of recent conclusive evidence that evaluates its efficacy in chronic stroke patients. The purpose of this review was to synthesize existing evidence on the efficacy of mobilization with movement therapy on range of motion, balance, and gait performance in subjects after stroke.

Methods

A comprehensive systematic search of literature was performed using the following databases: PubMed/Medline, CINAHL, AMED, PEDro, Cochrane Library, and Scopus. Physiotherapy Evidence Database (PEDro) scale was used to evaluate the methodological quality of included trials. The primary outcome measures of this review were dorsiflexion range of motion (DF-ROM), and Berg balance scale (BBS). This review was reported in accordance with PRISMA statement guidelines. Due to variations in relevant trials, meta-analysis was not carried out.

Results and Conclusions

Seven randomized controlled trials with a total of 224 subjects were analyzed. Evidence of overall quality was graded from moderate to high. This review found that mobilization with movement therapy could be an alternative rehabilitative intervention for subjects with chronic stroke to increase range of motion, balance, and gait ability. However, the evidence remains preliminary due to the small number of participants. Large-scale RCTs in the future are warranted to investigate the efficacy of mobilization with movement in subgroups of chronic stroke subjects.

Effect of robotic-assisted ankle training on gait in stroke participants: A case series study

BACKGROUND

Robotic rehabilitation therapy has grown rapidly during the last two decades allowing researchers and clinicians to deliver high-intensity training to persons with sensorimotor disorders caused by neurological injuries and diseases.

METHODS

This case series reports the effect of robot-assisted, impairment-oriented training for persons recovering from stroke on impairment of the paretic ankle as well as on the kinematic and spatiotemporal parameters of gait. Five persons with chronic stroke (>6 months post-stroke) participated in a 10-week training protocol, receiving three, 30-min sessions per week of a robot-assisted therapy. The robot-assisted intervention cyclically induced dorsiflexion and plantarflexion to the ankle at 5 degrees/s through ±15 degrees while the participants assisted with the imposed movement. Concurrently, participants received visual feedback of their active, assistive torque as well as targeted mechanical vibration of the ankle tendons when lengthened by the applied motion. Walking speed, cadence, step length of the non-paretic leg, percentage of paretic single limb support during the gait cycle, and ankle strength were assessed just before training began (baseline), after the last training session (post-training), and 3 months post-training (follow-up).

DISCUSSION

Robot-assisted training that provided assisted movement, biofeedback, and proprioceptive stimulation reduced ankle impairment and improved kinematic and spatiotemporal gait parameters, suggesting that impairment-oriented therapy applied to the paretic ankle may provide a valuable adjunct to locomotor therapies in persons with chronic gait disorders due to stroke.

Effects of bi-axial ankle strengthening on muscle co-contraction during gait in chronic stroke patients: A randomized controlled pilot study

INTRODUCTION

Ankle dysfunction in patients with stroke is a common but serious cause of balance and gait impairments. However, comprehensive paretic ankle training seldom exists. Thus, we investigated the effects of a bi-axial ankle muscle training program using visual feedback as a means to improve ankle strength and performance of functional activities in patients with stroke.

METHODS

This study was a randomized controlled pilot trial with concealed allocation and assessor blinding and intention-to-treat analysis. Twenty-five patients with stroke and difficulty in walking (e.g., foot drop) or ankle muscle weakness receiving inpatient rehabilitation were included. The experimental group underwent ankle muscle training consisting of passive stretching, control of ankle muscles, and active-resistive strengthening using visual feedback for 40 min per day, 5 times per week for 4 weeks. The control group underwent ankle-related physical therapy, including ankle range-of-motion exercises. The amount of time for training was equal between the two groups. The outcome measurements were isometric ankle contraction force to assess the strength of ankle muscles, ankle proprioception, Fugl-Meyer lower extremity score, Berg balance scale score, walking speed, and ankle co-contraction index to assess muscle efficiency during gait.

RESULTS

The analysis revealed significant between-group differences in the ankle muscle strength in each direction (P < 0.05), Fugl-Meyer score (P < 0.01), and stance-phase co-contraction index (P < 0.05). After training, the experimental group displayed significant within-group differences in the strength of the ankle muscles in each direction (P < 0.01), ankle proprioception (P < 0.05), and walking speed (P < 0.05).

CONCLUSIONS

Our findings demonstrate the significant short-term effects of ankle muscle training on strength, walking speed, and muscle efficiency in patients with chronic stroke.

Manual Therapy in Preadolescent Children: A Delphi Investigation of Physical Therapists in the United States

OBJECTIVE

Limited research has investigated the use of manual therapy to treat the preadolescent (0-12 years of age) population with musculoskeletal and neurological impairments. The purpose of this study was to identify the following among physical therapists holding advanced credentials in pediatrics, neurodevelopmental treatment, or manual therapy: (1) consensus regarding effective techniques in the preadolescent population, (2) differences in opinion, and (3) perceived decision-making barriers and factors regarding use of manual therapy techniques.

METHODS

Credentialed physical therapists in the United States were recruited for a 3-round Delphi investigation. An electronic survey in Round 1 identified musculoskeletal and neurological impairments and the manual techniques considered effective to treat such conditions, in addition to factors and barriers. Responses were used to create the second round, during which a 4-point Likert scale was used to score each survey item. A third round of scoring established consensus. Descriptive statistics and composite scores were calculated for each manual technique by impairment. Between-group differences were calculated using the Mann-Whitney U test with Bonferroni correction.

RESULTS

Consensus was determined for several concepts. First, neuromuscular techniques were considered effective across all impairments, and joint mobilizations (grades I-IV) were believed to be effective to treat joint and muscle and myofascial impairments. Second, visceral manipulation and craniosacral therapy were considered ineffective in treating most impairments. There was lack of consensus and clear differences of opinion regarding the use of grade V mobilizations and dry needling. Significant barriers to use of manual therapy were: lack of knowledge, lack of evidence, and fear of litigation and harming patients.

CONCLUSION

This study is an initial step for developing manual therapy guidelines, research, and educational opportunities regarding manual therapy in pediatric physical therapy.

Nonsurgical Treatment Options for Muscle Contractures in Individuals With Neurologic Disorders: A Systematic Review With Meta-Analysis

OBJECTIVE

To investigate whether nonsurgical treatment can reduce muscle contractures in individuals with neurologic disorders. The primary outcome measure was muscle contractures measured as joint mobility or passive stiffness.

DATA SOURCES

Embase, MEDLINE, Cumulative Index to Nursing and Allied Health, and Physiotherapy Evidence Database in June-July 2019 and again in July 2020.

STUDY SELECTION

The search resulted in 8020 records, which were screened by 2 authors based on our patient, intervention, comparison, outcome criteria. We included controlled trials of nonsurgical interventions administered to treat muscle contractures in individuals with neurologic disorders.

DATA EXTRACTION

Authors, participant characteristics, intervention details, and joint mobility/passive stiffness before and after intervention were extracted. We assessed trials for risk of bias using the Downs and Black checklist. We conducted meta-analyses investigating the short-term effect on joint mobility using a random-effects model with the pooled effect from randomized controlled trials (RCTs) as the primary outcome. The minimal clinically important effect was set at 5°.

DATA SYNTHESIS

A total of 70 trials (57 RCTs) were eligible for inclusion. Stretch had a pooled effect of 3° (95% CI, 1-4°; prediction interval (PI)=-2 to 7°; I 2=66%; P<.001), and robot-assisted rehabilitation had an effect of 1 (95% CI, 0-2; PI=-8 to 9; I 2=73%; P=.03). We found no effect of shockwave therapy (P=.56), physical activity (P=.27), electrical stimulation (P=.11), or botulinum toxin (P=.13). Although trials were generally of moderate to high quality according to the Downs and Black checklist, only 18 of the 70 trials used objective measures of muscle contractures. In 23 trials, nonobjective measures were used without use of assessor-blinding.

CONCLUSIONS

We did not find convincing evidence supporting the use of any nonsurgical treatment option. We recommend that controlled trials using objective measures of muscle contractures and a sufficiently large number of participants be performed.

Functional outcome of joint mobilization added to task-oriented training on hand function in chronic stroke patients

Background

Approximately half of stroke patients show impaired upper limb and hand function. Task-oriented training focuses on functional tasks, while joint mobilization technique aims to restore the accessory movements of the joints.

Objective

To investigate the effect of adding joint mobilization to task-oriented training to help the patients in reaching a satisfactory level of recovery for their hand function.

Patients and methods

Thirty chronic stroke patients with paretic hand participated in the study; they were divided equally into study and control groups. The study group received joint mobilization followed by task-oriented training for the affected hand. Meanwhile, the control group received task-oriented training only. Both groups received their treatment in the form of 3 sessions per week for 6 successive weeks. The primary outcome measures were hand function that was assessed by Jebsen-Taylor hand function test (JTT) and active and passive wrist extension range of motion (ROM) that was measured by a standard goniometer. The secondary outcome measure was the grip strength of the hand that was assessed by a JAMAR adjustable hand dynamometer.

Results

There was a significant improvement in all the outcome measurements in both groups that were more evident in the study group.

Conclusion

Combining joint mobilization with task-oriented training had a highly significant effect in improving the hand function in chronic stroke patients compared to task-oriented training alone.

Immediate Effects of Ankle Joint Mobilization With Movement on Postural Control, Range of Motion, and Muscle Strength in Healthy Individuals: A Randomized, Sham-Controlled Trial

CONTEXT

Ankle proprioception is one of the crucial components contributing to postural control. Although the effects of Mulligan's mobilization with movement (MWM) on postural control, ankle dorsiflexion range of motion (DFROM), and muscle strength in people with ankle disorders have previously been investigated, it is still unclear whether ankle MWM had ability to change postural control, DFROM, and muscle strength.

OBJECTIVES

To reveal pure effects of MWM on postural control, ankle DFROM, and muscle strength in healthy individuals.

DESIGN

A prospective, randomized, double-blinded, sham-controlled study.

SETTING

Musculoskeletal laboratory, Dokuz Eylul University, Turkey.

PARTICIPANTS

Forty students in good health recruited from a local university.

INTERVENTIONS

Mulligan's MWM or sham application over ankle joint.

MAIN OUTCOME MEASURES

The primary outcome was postural control and measured using limits of stability (LOS) test. The secondary outcomes were tibialis anterior muscle strength and ankle DFROM, which were measured using handheld dynamometer and weight-bearing lunge test, respectively. All outcomes were assessed before and immediately after intervention.

RESULTS

Left and right ankle DFROM and LOS overall score showed a statistically significant improvement compared with first measurement in both groups (P < .05). However, LOS time was significantly improved only in the MWM group (P < .05). Statistical analyses of between-group mean differences showed that Mulligan's MWM provided significant improvement in the LOS in forward-right direction compared with sham application (P = .03).

CONCLUSIONS

The results of this study suggest that the application of Mulligan's MWM on ankle joint might be beneficial to improve postural control in forward right direction in individuals with healthy ankles. On the other hand, both MWM and sham application were able to increase overall postural control and DFROM, and MWM had no superiority over sham application for increasing these 2 variables.

Changes in Ankle Range of Motion, Gait Function and Standing Balance in Children with Bilateral Spastic Cerebral Palsy after Ankle Mobilization by Manual Therapy

The aim of this study was to investigate the effect of ankle joint mobilization in children with cerebral palsy (CP) to ankle range of motion (ROM), gait, and standing balance. We recruited 32 children (spastic diplegia) diagnosed with CP and categorized them in two groups: the ankle joint mobilization (n = 16) group and sham joint mobilization (n = 16) group. Thus, following a six-week ankle joint mobilization, we examined measures such as passive ROM in ankle dorsiflexion in the sitting and supine position, center of pressure (COP) displacements (sway length, area) with eyes open (EO) and closed (EC), and a gait function test (timed up and go test (TUG) and 10-m walk test). The dorsiflexion ROM, TUG, and 10-m walk test significantly increased in the mobilization group compared to the control group. Ankle joint mobilization can be regarded as a promising method to increase dorsiflexion and improve gait in CP-suffering children.

Short-term Effects of Mulligan's Mobilization With Movement on Pain, Function, and Emotional Aspects in Individuals With Knee Osteoarthritis: A Prospective Case Series

OBJECTIVE

To evaluate the short-term effects of Mulligan's mobilization with movement (MWM) on pain, physical function, emotional aspects, and proprioceptive acuity after a 2-week treatment period and throughout a 3-week follow-up period.

METHODS

A single group of 30 participants (60.96 ± 5.16 years) with symptomatic knee osteoarthritis (KOA) was evaluated. The protocol involved 5 evaluations moments, before (baseline) and after 2 weeks of intervention (24 hours after the last session), and at 3-week follow-up. The intervention included 3 Mulligan's MWM techniques. The variables evaluated were pain (pressure pain threshold and Visual Numeric Scale), physical function (range of motion, proprioceptive acuity, and the Western Ontario and McMaster Universities Osteoarthritis Index) and emotional aspects (Beck Depression Inventory). Analysis of variance for repeated measures was used considering a significance level of 5%.

RESULTS

At the second evaluation (after intervention), the pressure pain threshold presented higher values for rectus femoris, tibialis anterior, and patellar tendon sites and reduced values for the Visual Numeric Scale, Beck Depression Inventory, and Western Ontario and McMaster Universities Osteoarthritis Index compared with baseline. Also, during the follow-up period, all variables returned close to baseline levels. Proprioceptive acuity and range of motion did not present significant changes.

CONCLUSION

Scores for pain relief, physical function, and emotional aspects improved after a course of MWM in this single group of individuals with KOA. Mobilization with movement had limited outcome during follow-up. It suggests that future clinical trials on the use of MWM for KOA should be considered.

Four-week training involving ankle mobilization with movement versus static muscle stretching in patients with chronic stroke: a randomized controlled trial

BACKGROUND

Patients with stroke generally have diminished balance and gait. Mobilization with movement (MWM) can be used with manual force applied by a therapist to enhance talus gliding movement. Furthermore, the weight-bearing position during the lunge may enhance the stretch force.

OBJECTIVES

This study aimed to compare the effects of a 4-week program of MWM training with those of static muscle stretching (SMS). Ankle dorsiflexion passive range of motion (DF-PROM), static balance ability (SBA), the Berg balance scale (BBS), and gait parameters (gait speed and cadence) were measured in patients with chronic stroke.

METHODS

Twenty patients with chronic stroke participated in this study. Participants were randomized to either the MWM (n = 10) or the SMS (n = 10) group. Patients in both groups underwent standard rehabilitation therapy for 30 min per session. In addition, MWM and SMS techniques were performed three times per week for 4 weeks. Ankle DF-PROM, SBA, BBS score, and gait parameters were measured after 4 weeks of training.

RESULTS

After 4 weeks of training, the MWM group showed significant improvement in all outcome measures compared with baseline (p < 0.05). Furthermore, SBA, BBS, and cadence showed greater improvement in the MWM group compared to the SMS group (p < 0.05).

CONCLUSIONS

This study demonstrated that MWM training, combined with standard rehabilitation, improved ankle DF-PROM, SBA, BBS scores, and gait speed and cadence. Thus, MWM may be an effective treatment for patients with chronic stroke.

Technology-Assisted Ankle Rehabilitation Improves Balance and Gait Performance in Stroke Survivors: A Randomized Controlled Study With 1-Month Follow-Up

Many stroke survivors have limited ankle range of motion (ROM) caused by weak dorsiflexors and stiff plantarflexors. Passive ankle stretching exercises with physical therapists or a stretching board are usually recommended, but these treatments have some limitations (e.g., cost and availability of physical therapists). In this paper, we assessed the results of ankle stretching exercises delivered by a robotic ankle stretching system called motorized ankle stretcher (MAS) that we developed or by a stretching board on ankle ROM, balance control, and gait performance. The 16 stroke survivors were randomly assigned to an intervention group (IG) or a control group (CG) and participated in seven sessions of dorsiflexion stretching exercises for three-and-a-half consecutive weeks. Laboratory assessments included pre-assessment (baseline at the beginning of the first exercise session), post-assessment (at the end of the seventh exercise session), and retention assessment (one month after the seventh exercise session). All assessments included ankle ROM for the affected side, static/dynamic balance control with a sensory organization test (SOT), walking speed, walking cadence, and step length for the affected and unaffected sides. During seven sessions of ankle stretching exercises, the IG performed them using the MAS, and the CG used a stretching board. The IG significantly improved ankle ROM, SOT scores (i.e., static/dynamic balance control), walking speeds, walking cadences, and step lengths for the unaffected side after completing the seven exercise sessions of ankle stretching exercises and maintained the enhancements at the retention assessment. The CG did not significantly improve across the majority of outcome measures except for the SOT scores between the pre-assessment and retention assessment. Future work will investigate the ideal intensity, frequency, and duration of exercising with the MAS. Our research on technology-assisted ankle rehabilitation, which can ascertain the level of persistent improvement, long-term performance retention, and carry-over effects in stroke survivors, can be used to inform future designs.

Interventions involving repetitive practice improve strength after stroke: a systematic review

QUESTIONS

Do interventions involving repetitive practice improve strength after stroke? Are any improvements in strength accompanied by improvements in activity?

DESIGN

Systematic review of randomised trials with meta-analysis.

PARTICIPANTS

Adults who have had a stroke.

INTERVENTION

Any intervention involving repetitive practice compared with no intervention or a sham intervention.

OUTCOME MEASURES

The primary outcome was voluntary strength in muscles trained as part of the intervention. The secondary outcomes were measures of lower limb and upper limb activity.

RESULTS

Fifty-two studies were included. The overall SMD of repetitive practice on strength was examined by pooling post-intervention scores from 46 studies involving 1928 participants. The SMD of repetitive practice on strength when the upper and lower limb studies were combined was 0.25 (95% CI 0.16 to 0.34, I²=44%) in favour of repetitive practice. Twenty-four studies with a total of 912 participants investigated the effects of repetitive practice on upper limb activity after stroke. The SMD was 0.15 (95% CI 0.02 to 0.29, I²=50%) in favour of repetitive practice on upper limb activity. Twenty studies with a total of 952 participants investigated the effects of repetitive practice on lower limb activity after stroke. The SMD was 0.25 (95% CI 0.12 to 0.38, I²=36%) in favour of repetitive practice on lower limb activity.

CONCLUSION

Interventions involving repetitive practice improve strength after stroke, and these improvements are accompanied by improvements in activity.

Effectiveness of Faradic and Russian currents on plantar flexor muscle spasticity, ankle motor recovery, and functional gait in stroke patients

BACKGROUND AND PURPOSE

Spasticity is a major disabling symptom in patients post stroke. Though studies have demonstrated that electrical stimulation (ES) can reduce spasticity and improve passive ankle range of motion (ROM), not many studies have evaluated the effectiveness of ES on active ankle ROM. The purpose of this study was to determine the effectiveness of Faradic and Russian currents in the reduction of ankle plantar-flexor spasticity and improving motor recovery in patients post stroke.

METHODS

Eighty-three patients (29 females and 54 males; mean age of 57.12 years) were randomly assigned to Group 1 (task-oriented exercises), Group 2 (Faradic current for 10 min and task-oriented exercises), and Group 3 (Russian current for 10 min and task-oriented exercises) for a period of 5 sessions per week for 6 weeks. All patients were assessed for soleus and gastrocnemius muscles spasticity measured by modified modified Ashworth scale; active and passive range ROM measured by goniometer; and functional ambulation measured by modified Emory Functional Ambulation Profile at the time of recruitment to study and after 6 weeks.

RESULTS

Both the types of stimulation and exercises were not associated with improvements in modified Emory Functional Ambulation Profile (p > 0.05). The results showed that all the groups are effective in improving passive ankle ROM (p < 0.05) and reducing soleus and gastrocnemius muscles spasticity (p < 0.05). Though all the groups were effective in improving active ankle ROM, no group was found to be superior to another after treatment CONCLUSION: Adding ES to exercises are associated with low to medium effect sizes (<0.5) in reducing spasticity and improving ankle ROM.

Change in Coefficient of Fatigability Following Rapid, Repetitive Movement Training in Post-Stroke Spastic Paresis: A Prospective Open-Label Observational Study

BACKGROUND

In post-stroke patients, the possibility of performing an active ankle dorsiflexion movement is favorable for the recovery of gait. Moreover, the fatigue due to repetitive active ankle dorsiflexion could reduce the speed gait. We assessed the change in coefficient of fatigability of active ankle dorsiflexion after a home-based self-rehabilitative procedure in post-stroke patients.

METHODS

In a prospective open-label observational study conducted in 2 university hospitals, a home-based self-rehabilitation treatment comprising two 12-minute sessions per day (3 times per week for 3 months) was performed by 10 outpatients with post-stroke lower limb impairment. Each session consisted of three 1-minute series of repeated active ankle dorsiflexion efforts at maximal speed on the paretic side, each one followed by 3-minute bouts of triceps surae stretch. Coefficients of fatigability of dorsiflexion and 10-meter barefoot ambulation speed were evaluated at baseline and at the end of the program.

RESULTS

At 3 months of follow-up, there was a decrease in the coefficients of fatigability of ankle dorsiflexion, both with knee flexed and extended (respectively from 8% to 2% and from 6% to 2%; P < .01), associated with an increase in comfortable ambulation speed (from .24 to .26 m/s; P < .05).

CONCLUSIONS

The reduction of coefficient of fatigability of ankle dorsiflexion, together with walking speed improvement, suggested the effectiveness of self-rehabilitation using alternated periods of self-stretch and rapid alternating efforts in the paretic lower limb after stroke.
