Standing balance and dynamic weight shifting were evaluated in 10 subjects with hemiplegia using a sensory organization balance test (SOT) and the Fugl-Meyer sensorimotor assessment (FMSA). The SOT is a timed balance test that evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. In contrast, the FMSA is a functional(More)
The purpose of this study was to describe the patterns of postural adjustments during induced body sway in healthy subjects and hemiplegic patients. Electromyograms were taken with surface electrodes from four lower extremity muscles that control ankle, knee, and hip motions. During postural adjustments in 10 healthy subjects, the ankle muscle and the(More)
The symmetry and adaptability of long latency stretch responses was studied in a group of 4 adult hemiplegics and 5 normals of similar age. Subjects stood on a moveable platform which directly rotated the ankles unexpectedly during a series of horizontal anterioposterior (AP) translations. When the platform was rotated toes-up, long latency discharge of(More)
The onset latency and discharge amplitude of preprogrammed postural responses were evaluated in order to determine if the structure of synergistic activation could be altered by ligamentous laxity at the knee joint. Twelve subjects with unilateral and one subject with bilateral anterior cruciate ligament (ACL) insufficiency were tested while standing on a(More)
The purpose of this study was to analyze the effects of prior instruction on automatic postural responses and voluntary postural sways measured about the ankle joint. Ten subjects with right hemiplegia resulting from a cerebrovascular accident (mean age = 56 +/- 14 years) and 5 healthy subjects (mean age = 47 +/- 6 years) stood symmetrically on a movable(More)
STUDY DESIGN Prospective, multicenter research design. OBJECTIVES To assess functional and health status outcomes in patients following a physical therapy program after rotator cuff repair surgery, and to determine the impact of selected patient medical comorbidities on rehabilitation outcomes. BACKGROUND While authors have studied the influence of(More)
Peripheral sensory modulation of balance behavior may require a “calibrated” mechanism which would maintain upright standing by a feedback control of torque at the ankle joint. The calibration of human balance was studied using a systematic presentation of perturbation excursions and velocities in normal freely standing subjects. All perturbations(More)
OBJECTIVES To assess balance, dynamic gait, and dynamic visual acuity outcomes after a vestibular and balance rehabilitation program and to determine which variables were significantly associated with improved balance and ambulation. DESIGN Retrospective case series. SETTING Outpatient setting at a tertiary care facility. PARTICIPANTS Twenty patients(More)
The purpose of this study was to examine the effects of a rapid length change in the elongated and shortened ankle muscles of subjects with hemiplegia during forward body sway. The onset and amplitude of electrical activity in the ankle muscles of four standing hemiplegic subjects with mild stretch reflex abnormalities and four healthy subjects were(More)
Standing balance was evaluated in ten subjects with hemiplegia using a sensory organization balance test (SOT). The SOT is a timed balance test which evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. The duration of bilateral stance was assessed using combinations of three visual and two support surface conditions.(More)
