The benefits of a functional electrical stimulation (FES) gait programme were assessed in a group of 6 incomplete spinal cord injured subjects. Measurements were made of quadriceps spasticity, lower limb muscle strength, postural stability in standing, spatial and temporal values of gait, physiological cost of gait and independence in activities of daily(More)
BACKGROUND AND PURPOSE It has been suggested that cyclic neuromuscular electrical stimulation (ES) may enhance motor recovery after stroke. We have investigated the effects of ES of the wrist extensors on impairment of wrist function and on upper-limb disability in patients being rehabilitated after acute stroke. METHODS We recruited 60 hemiparetic(More)
This study investigated the possibility of using uni-axial gyroscopes to develop a simple portable gait analysis system. Gyroscopes were attached on the skin surface of the shank and thigh segments and the angular velocity for each segment was recorded in each segment. Segment inclinations and knee angle were derived from segment angular velocities. The(More)
BACKGROUND The accurate measurement of physical activity is crucial to understanding the relationship between physical activity and disease prevention and treatment. OBJECTIVE The primary purpose of this study was to investigate the validity and reliability of the activPAL physical activity monitor in measuring step number and cadence. METHODS The(More)
The primary purpose of this study was to investigate the accuracy of the activPAL physical activity monitor in measuring step number and cadence in older adults. Two pedometers (New-Lifestyles Digi-Walker SW-200 and New-Lifestyles NL2000) used in clinical practice to count steps were simultaneously evaluated. Observation was the criterion measure.(More)
In this study two aspects of hybrid functional electrical stimulation (FES) orthoses were investigated: joint motion constraints and FES control strategies. First, the effects of joint motion constraints on the gait of normal subjects were investigated using modern motion analysis systems, including electromyogram (EMG) and heart rate measurements. An(More)
In the restoration of gait for paraplegics using functional electrical stimulation, the method most commonly used to produce hip flexion for the swing phase of gait has been the elicitation of the flexion withdrawal response. Several problems have been noted with the response: there is a decrease in the magnitude of the hip flexion to repeated stimuli(More)
BACKGROUND Contractures are common in a stroke population, yet there is little information on the time course of development. OBJECTIVES Investigate quantitatively changes associated with contracture formation in an acute stroke population. STUDY DESIGN Longitudinal study on 22 subjects who were 2-4 weeks post stroke. OUTCOME MEASURES Contractures(More)
OBJECTIVE To study the application of partial weight-bearing (PWB) supported treadmill gait training augmented by functional electric stimulation (FES) in subjects with acute incomplete spinal cord injury (SCI). DESIGN Before-after crossover trial with control (A) and intervention (B) periods. SETTING Physiotherapy (PT) department of a spinal injuries(More)
Limitations of mechanical walking orthoses for paraplegics are high energy consumption and upper limb loading. Flexing of the knee during swing phase has been used as a means of attempting to reduce these. It has been found that this has little effect because using knee flexion results in no change in the compensatory mechanisms required for swing foot(More)
