STUDY DESIGN Controlled laboratory study, repeated-measures design. OBJECTIVES To compare hip abductor muscle activity during selected exercises using fine-wire electromyography, and to determine which exercises are best for activating the gluteus medius and the superior portion of the gluteus maximus, while minimizing activity of the tensor fascia lata(More)
The purpose of this investigation was to determine if training isometrically with electrical stimulation (ES) alone would significantly increase isometric strength of the quadriceps femoris muscle. The relationships between the strength changes and the relative force and duration of training contractions were also studied. An experimental group (Group 1)(More)
This review of the published literature presents and discusses major findings and observations concerning the effects of high frequency electrical stimulation (ES) on strengthening the quadriceps femoris of healthy subjects. The paper does not focus on clinical studies, although clinical uses of ES, suggestions for further research, and measurement(More)
STUDY DESIGN Multifactorial, repeated-measures, within-subjects design. OBJECTIVES To investigate the immediate effects of scapular taping on surface electromyographic (EMG) signal amplitude of shoulder girdle muscles during upper extremity elevation in individuals with suspected shoulder impingement syndrome. BACKGROUND Individuals with shoulder(More)
Therapeutic ultrasound is used clinically to enhance healing of pressure ulcers. Limited clinical research is available and no consensus exists regarding the efficacy of ultrasound for treating pressure ulcers, particularly full-thickness pressure ulcers, in the elderly. To assess the efficacy of pulsed low-intensity ultrasound on wound healing, a(More)
BACKGROUND Low back pain remains a costly quality-of-life-related health problem. Microdiscectomy is often the surgical procedure of choice for a symptomatic, single-level, lumbar disc herniation in younger and middle-aged adults. The question of whether a post-microdiscectomy exercise program enhances function, quality of life, and disability status has(More)
BACKGROUND Restoration of physical function following lumbar microdiskectomy may be influenced by the postoperative care provided. OBJECTIVE The purpose of this study was to examine the effectiveness of a new interventional protocol to improve functional performance in patients who have undergone a single-level lumbar microdiskectomy. SETTING The study(More)
OBJECTIVE To investigate the effects of medium frequency burst-modulated alternating current on the current amplitude necessary to produce maximally tolerated electrically stimulated quadriceps femoris isometric knee extension torque. DESIGN Ten healthy volunteers participated in this study. Neuromuscular electrical stimulation was applied to the(More)
Electrophysical agents (EPAs), including electrotherapy, are important components of patient/client management. A recent study by Springer et al. has elucidated the pattern of use and factors in clinical decision-making by Israeli physiotherapists regarding EPAs. It is evident from their data that EPAs, especially those related to electrotherapy, are still(More)
