OBJECTIVES To review the existing literature on treatments of unilateral neglect, to synthesize findings, and to offer recommendations for future studies. DATA SOURCES Computerized databases including MEDLINE and PsychINFO. STUDY SELECTION All studies investigating treatment(s) of unilateral neglect. DATA EXTRACTION Authors reviewed design and other(More)
The task of gait initiation (GI), or taking a first step from a static standing position requires the development of forward momentum while maintaining dynamic balance as the body's center of mass (COM) moves forward and outside the base of support. The dynamics of GI in children (aged 7-12 years) with hemiplegic cerebral palsy (CP), diplegic CP and(More)
OBJECTIVE To compare the effectiveness of errorless learning versus trial and error learning for teaching activities of daily living to patients with acute stroke with or without explicit memory impairments. DESIGN Randomized crossover. SETTING Rehabilitation hospital. PARTICIPANTS Thirty-three adult subjects following an acute stroke. INTERVENTION(More)
The use of surface electromyography (sEMG) recorded during ambulation has provided valuable insight into motor development and changes with age in the pediatric population. However, no studies have reported sEMG differences with age in the children with cerebral palsy (CP). In this study, data from 50 children were divided retrospectively into four groups,(More)
OBJECTIVE To assess test-retest reliability of the peak resistance torque and slope of work methods of spasticity measurement of the knee flexors and extensors in children with cerebral palsy (CP). DESIGN Test-retest reliability study. SETTING Pediatric orthopedic hospital. PARTICIPANTS Fifteen children with CP. INTERVENTION Knee extensor and flexor(More)
A 12-year-old boy with hemiplegic cerebral palsy (CP) presented with decreased function in his left upper extremity. He was treated with a 3-week protocol of constraint-induced therapy (CIT) consisting of six 2-hour sessions of physical and occupational therapy, plus home practice. Improvements in upper-extremity function were found in the mean and median(More)
The feasibility of using percutaneous intramuscular functional electric stimulation (FES) in children with cerebral palsy (CP) as a method to improve ankle kinematics and kinetics during gait was investigated. Two children with right hemiplegic CP had percutaneous intramuscular electrodes implanted into the gastrocnemius and tibialis anterior muscles of the(More)
BACKGROUND Co-contraction is an impairment commonly reported in children with cerebral palsy. However, co-contraction has not been investigated during passive movements which may be used to assess spasticity in children with cerebral palsy. The purpose of this study was to examine the frequency of co-contraction and the relationship between reflex activity(More)
The feasibility of percutaneous intramuscular functional electrical stimulation (P-FES) in children with cerebral palsy (CP) for immediate improvement of ankle kinematics during gait has not previously been reported. Eight children with CP (six with diplegia, two with hemiplegia; mean age 9 years 1 month [SD 1 y 4 mo; range 7 y 11 mo to 11 y 10 mo]) had(More)
The objective of this study was to examine the effectiveness of a program of traditional outpatient neurological rehabilitation that included home forced use. In total, 17 patients with chronic stroke and 1 patient with subacute stroke (mean time poststroke = 27.6 months) completed an individualized program consisting of seven 2-hour treatment sessions(More)
