Effects of BIONESS in Rehabilitation of Stroke (EFES-BIO-SEP)

Short-term Therapeutic Effects of Functional Electrical Stimulation Device Bioness L300 on the Somatosensory Cortical Representation in the Rehabilitation of Patients After Stroke

A four-weeks randomized clinical two-period crossover-design study will be conducted. Each patient will be randomized in a two separate consecutive treatment periods (Parallel Group Design). "Group A" will be treated with functional electrical stimulation (FES) and a second "Gruppe B" will be treated without FES for two weeks. After this period Group A and Group B will switched.

Study Overview

• Status: Completed
• Conditions: Stroke
• Intervention / Treatment: Device: Bioness-300

Detailed Description

Prediction of motor recovery in the upper-limb (UL) / lower-limb (LL) in patients with stroke is generally based on clinical examination. However, according to former studies neurophysiological measures may also have a predictive value. In the acute phase, the combination of the motor score and SEPs are best predictive of outcome. Neurophysiological measures alone are of limited value in predicting long term outcome. However, predictive accuracy is substantially improved through the combined use of both of these measures and clinical variables.

A four-weeks randomized clinical two-period crossover-design study will be conducted. Each patient will be randomized in a two separate consecutive treatment periods (Parallel Group Design). "Group A" will be treated with functional electrical stimulation (FES) and a second "Gruppe B" will be treated without FES for two weeks. After this period Group A and Group B will switched.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
SEP measurement	in improving pathological latencies and / or amplitudes of somatosensory evoked potentials (SEPs) • N35, P40, N50 (lower limb / tibial nerve) amplitude of somatosensory evoked potential [ Time Frame: Change from baseline at 4 weeks]	4 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
