Immediate effects of TECAR therapy on lower limb to decrease hypertonia in chronic stroke survivors: a randomized controlled trial.

PURPOSE: To analyze immediate effects of TECAR therapy (TT) to reduce lower limb hypertonia and improve functionality in chronic post-stroke. MATERIALS AND METHODS: It is a single-blind randomized controlled clinical trial. A total of 36 chronic stroke survivors were divided into two groups. The experimental group received a single 30-minute session of TT with functional massage (FM) on lower limb. The control group received a single 30-minute session sham treatment of TT plus FM. The primary outcome measure was hypertonia (Modified Ashworth Scale, MAS). Secondary outcomes were gait speed (4-Meter Walk-Test), standing knee-flexion (Fugl-Meyer Assessment Scale IV-item), change in weight bearing ankle dorsiflexion (Ankle Lunge Test, ALT), and functional lower limb strength (5-Times Sit-to-Stand Test). All measurements were performed at baseline, immediately and 30-minutes after treatment. RESULTS: There was a group-time interaction in MAS-knee (p = 0.044), MAS-ankle (p = 0.018) and ALT (p = 0.016) between T1 and T0 (p<.0001) and T2 and T0 (p<.0001) for the experimental group. There was a significant increase in ALT between T1 and T0 (p = 0.003) in the control group. CONCLUSIONS: A single session of TT performed at the same time as FM immediately reduces plantar-flexors and knee-extensor muscle hypertonia and increases change in weight bearing ankle dorsiflexion in chronic stroke survivors.

Capacitive and resistive electric transfer (TECAR) therapy may improve ankle mobility in stroke survivors.TECAR therapy may improve knee mobility in post-stroke.TECAR therapy may reduce lower limb muscle tone in stroke survivors.TECAR therapy could be used in combination with physiotherapy as a safe technique for the immediate reduction of hypertonia in stroke survivors.

Immediate Effects of TECAR Therapy on Gastrocnemius and Quadriceps Muscles with Spastic Hypertonia in Chronic Stroke Survivors: A Randomized Controlled Trial.

BACKGROUND: The aim of this study was to assess changes in muscle properties after a single session of capacitive and resistive energetic transfer (TECAR) therapy on spastic gastrocnemius and quadriceps muscles in chronic post-stroke. METHODS: A total of 36 chronic stroke survivors with lower limb hypertonia were enrolled in a double-blind randomized controlled trial. The experimental group (n = 18) received a single 30 min session of TECAR therapy in combination with functional massage (FM) on the gastrocnemius and quadriceps muscles. The control group (n = 18) received a sham treatment of TECAR therapy (without electrical stimulation) in combination with real FM. The primary outcome was muscle tone of the lower limb muscles assessed with the Modified Ashworth Scale (MAS). The secondary outcomes were goniometric degrees of the MAS (goniometer), neuromuscular properties of the gastrocnemius/quadriceps (myotonometer), and passive range of motion (inclinometer). All measurements were performed at baseline (T0), immediately after treatment (T1), and at 30 min post-treatment (T2) by a blinded assessor. RESULTS: The MAS score ankle dorsiflexion significantly decreased at T0-T1 (p = 0.046), and the change was maintained at T0-T2 (p = 0.019) in the experimental group. Significant improvements were noted in the passive range of motion for knee flexion (p = 0.012) and ankle dorsiflexion (p = 0.034) at T2. In addition, knee flexion improved at T1 (p = 0.019). CONCLUSION: A single session of Tecar therapy at the same time with FM on the gastrocnemius and rectus femoris immediately reduces muscle tone and increases the passive range of motion of both ankle and knee in chronic stroke survivors. There were no significant changes in the neuromuscular properties measured with myotonometer.

Assessment of the 4-meter walk test test-retest reliability and concurrent validity and its correlation with the five sit-to-stand test in chronic ambulatory stroke survivors.

BACKGROUND: The 4-meter walk test (4-MWT) is a widely used measure to assess gait speed in the elderly but has not been validated for stroke survivors to date. OBJECTIVES: To assess the test-retest reliability and concurrent validity of the 4-MWT compared to the 10-meter walk test (10-MWT) as a measure of gait speed in chronic post-stroke. SECONDARY OUTCOME MEASURE: to assess the correlation of both gait measures with the 5 times sit-to-stand test (5TSTS). METHODS: A cross-sectional observational study was conducted. Reliability was assessed by intraclass correlation coefficient (ICC2,1), standard error of measurement (SEM) and minimal detectable change (MDC-95%). Bland & Altman analysis was used to quantify agreement between the 4-MWT and the 10-MWT. Two consecutive walking trials of the 4-MWT and 10-MWT followed by 5TSTS were performed all on the same day. A single researcher made all measurements. RESULTS: Thirty-six chronic ambulatory post-stroke (average age 58.56 ± 11.28 years) were analyzed at their self-selected walking speed with a dynamic start. The 4-MWT showed excellent concurrent validity and test-retest reliability: ICC2.1 = 0.991 (95% CI: 0.983, 0.996); SEM= 0.032 and MDC- 95% = 0.090 m/second) with a strong positive correlation with the 10-MWT (r = 0.957, p < 0.001). The Bland & Altman analysis showed a concordance of -0.05 m/second bias (p = 0.039) (95% limits of agreement: 0.20 to -0.29 m/second). The paired t-test showed no statistically significant difference in the mean of both walking tests (p < 0.091). However, there was only moderate correlation between the two gait assessments and the 5TSTS. CONCLUSIONS: This study indicates excellent test-retest reliability concurrent validity and strong correlation between 4-MWT and 10-MWT with a dynamic start at comfortable speed. The 4-MWT could be used as a measure of gait speed in both outpatients and home settings in chronic ambulatory stroke survivors.

Available apps for stroke telerehabilitation during corona virus disease 2019 confinement in Spain.

PURPOSE: Stroke is one of the leading causes of disability in the adult population. It is feasible to think about the use of telerehabilitation devices, such as the smartphone, to respond to the growing demand, even in isolation cases, such as during confinement due to coronavirus disease in 2020. It is intended to explore the available Apps for Spanish-speaking patients with Stroke for a specific sensory-motor rehabilitation process. MATERIALS AND METHODS: A search of the available apps in Google Play and Apple Store was carried out using the keywords "Stroke", "hemiplegia" and "hemiparesis". The Apps detected have been described and evaluated by an anonymous survey among stroke survivors. RESULTS: Nine Apps have been identified and explored, four of which are available in Spanish: "NeuroRHB", "Stroke Hope Health4TheWorld", "9zest stroke recovery" and "Farmalarm". Twelve survivors with stroke have participated in the anonymous survey evaluating with the best score the App "Farmalarm". CONCLUSIONS: There are few specific Apps for the Stroke rehabilitation of sensory-motor impairments, and with important limitations that prevent their incorporation into clinical practice. The creation and adaptation of Apps for health professionals such as physiotherapists and occupational therapists and their users are recommended.Implications for rehabilitationIt is necessary to create and adapt specific telerehabilitation tools to address sensory-motor disorders.Telerehabilitation should be introduced in the clinical practice of physiotherapy and occupational therapy.Telerehabilitation via App can be a solution, easily accessible by patients, to reduce healthcare inequality, intensify the rehabilitation process and provide continuity after discharge from the hospital.

Influence of Core-Stability Exercises Guided by a Telerehabilitation App on Trunk Performance, Balance and Gait Performance in Chronic Stroke Survivors: A Preliminary Randomized Controlled Trial.

Stroke is one of the main causes of disability. Telerehabilitation could face the growing demand and a good strategy for post-stroke rehabilitation. The aim of this study is to examine the possible effects of therapeutic exercises performed by an App on trunk control, balance, and gait in stroke survivors. A preliminary 12-week randomized controlled trial was developed. Thirty chronic stroke survivors were randomly allocated into two groups. Both groups performed conventional physiotherapy, in addition to, the experimental group (EG) had access to a telerehabilitation App to guide home-based core-stability exercises (CSE). Trunk performance was measured with the Spanish-Trunk Impairment Scale (S-TIS 2.0) and Spanish-Function in Sitting Test. Balance and gait were measured with Spanish-Postural Assessment Scale for Stroke patient, Berg Balance Scale and an accelerometer system. In EG was observed an improvement of 2.76 points in S-TIS 2.0 (p = 0.001). Small differences were observed in balance and gait. Adherence to the use of the App was low. CSE guided by a telerehabilitation App, combined with conventional physiotherapy, seem to improve trunk function and sitting balance in chronic post-stroke. Active participation in the rehabilitation process should be increased among stroke survivors. Further confirmatory studies are necessary with a large sample size.

Telerehabilitation for balance rehabilitation in the subacute stage of stroke: A pilot controlled trial.

BACKGROUND: Telerehabilitation has been proposed as an effective strategy to deliver post-stroke specific exercise. OBJECTIVE: To assess the effectiveness and feasibility of core stability exercises guided by a telerehabilitation App after hospital discharge. METHODS: Extension of a prospective controlled trial. Subacute stage stroke survivors were included at the time of hospital discharge where they had participated in a previous 5-week randomized controlled trial comparing conventional physiotherapy versus core stability exercises. After discharge, patients from the experimental group were offered access to telerehabilitation to perform core stability exercises at home (AppG), while those from the control group were subject to usual care (CG). The Spanish-version of the Trunk Impairment Scale 2.0 (S-TIS 2.0), Function in Sitting Test (S-FIST), Berg Balance Scale (BBS), Spanish-version of Postural Assessment for Stroke Patients (S-PASS), the number of falls, Brunel Balance Assessment (BBA) and Gait were assessed before and after 3 months intervention. RESULTS: A total of 49 subjects were recruited. AppG showed greater improvement in balance in both sitting and standing position and gait compared with CG, although no statistically significant differences were obtained. CONCLUSION: Core stability exercises Telerehabilitation as a home-based guide appears to improve balance in post-stroke stage. Future studies are necessary to confirm the effects as well as identifying strategies to increase telerehabilitation adherence.
