Home Based Electrical Stimulation on Post-stroke Lower Limb Tightness.
The Feasibility and Impact of A Home-Based NMES Program on Post-Stroke Lower Limb Spasticity
Spasticity is a common complication post stroke. Post-stroke spasticity along with weakness and lack of coordination result in gait abnormalities and functional limitations. Recent treatment option include neuromuscular electric stimulation (NMES), a form of therapy that applies electrical currents to produce contraction of innervated muscle by depolarizing local motor nerves. Currently, there are wide varieties of NMES devices available commercially for consumer.
The main purpose of this study is to evaluate the feasibility and acceptability of a home-based NMES program on lower limb spasticity in patient with post-stroke more than 6 months and to assess the impact of the program. This is single arm prospective intervention study. Patient will apply home-based NMES on their leg for 20 minutes, 5 days a week for 4 weeks. At the end of the study, an outcome measures will be assessed and patient will be required to answer a questionnaires on their experience.

Experimentell: Home-based Electrical Stimulation Program for lower limb spasticity
Single arm prospective intervention study to assess the feasibility and impact of a home-based program.
Patient will apply home-based NMES on their leg for 20 minutes, 5 days a week for 4 weeks.
At the end of the study, an outcome measures will be assessed and patient will be required to answer a questionnaires on their experience.
|
Home-based NMES program on spastic leg. The NMES pre-programmed dosage (locked): NMES waveform is biphasic PC, Frequency 50Hz, pulse width 400µs, ON:OFF 10s:20s and current amplitude: individual maximum tolerated to achieve ankle dorsiflexion.
