Preliminary testing of a dual-channel electrical stimulator for correction of gait.

چکیده
A dual-channel orthotic electrical stimulator was designed for daily use at home by plegic and paretic patients who had completed a hospital rehabilitation program. With two independent channels, two muscle groups can be stimulated in chosen sequences. A microcomputer accommodates the stimulation sequences to the gait cadence of the patient for the stance and swing phase separately.

The purpose of the present study was to investigate the effect of concurrent cognitive tasks activating phonological loop and visuospatial scratchpad of working memory on gait in older adults.12 older adults with the age range of 65-70 years performed walking trials in 3 counterbalanced testing conditions including single walking, walking while performing visuospatial task and walking while per...
متن کاملApplication of a programmable dual-channel adaptive electrical stimulation system for the control and analysis of gait.
A dual-channel electrical stimulation system with a stimulator and a programmer/stride analyzer was designed for clinical rehabilitation of gait and for subsequent daily use as an orthotic aid. The stimulator, with controls to adjust amplitude only (50 mA), adapts chosen stimulation sequences to the walking rate of a patient. Pulse duration (50-500 microseconds), frequency (5-120 Hz), shape (sy...
متن کاملA microcontroller system for investigating the catch effect: Functional electrical stimulation of the common peroneal nerve.
Correction of drop foot in hemiplegic gait is achieved by electrical stimulation of the common peroneal nerve with a series of pulses at a fixed frequency. However, during normal gait, the electromyographic signals from the tibialis anterior muscle indicate that muscle force is not constant but varies during the swing phase. The application of double pulses for the correction of drop foot may e...

The study objective was to assess the effect of functional electrical stimulation (FES) applied to the peroneal nerve and thigh muscles on gait performance in subjects with hemiparesis. Participants were 45 subjects (age 57.8 ± 14.8 years) with hemiparesis (5.37 ± 5.43 years since diagnosis) demonstrating a foot-drop and impaired knee control. Thigh stimulation was applied either to the quadric...

Objectives: This study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. Methods & Materials: This study was a analyse-comparative study. Subjects were chosen from three parks of Tehran. Subjects were 20 older adults with no history of falls (aged 72.60±5 years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±...
