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)
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)
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)
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)
Study Design Controlled laboratory study, repeated-measures design. Background Previous studies have reported that the superior and inferior portions of the gluteus maximus have different functional roles. Knowledge of how the different portions of the gluteus maximus are activated during therapeutic exercise may lead to more specific exercise prescription.(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)
