OBJECTIVE To compare the muscle activity of the abductor hallucis (AbdH) and the medial longitudinal arch (MLA) angle during toe curl (TC) and short foot (SF) exercises while sitting or in one-leg standing position. DESIGN Two-way repeated-measures ANOVA was used to analyze the effects of exercise type and position on the muscle activity of the AbdH and(More)
OBJECTIVE To determine the most effective exercise to specifically activate the scapular posterior tilting muscles by comparing muscle activity generated by different exercises (wall facing arm lift, prone arm lift, backward rocking arm lift, backward rocking diagonal arm lift). DESIGN Repeated-measure within-subject intervention. PARTICIPANTS The(More)
CONTEXT To improve selective infraspinatus muscle strength and endurance, researchers have recommended selective shoulder external-rotation exercise during rehabilitation or athletic conditioning programs. Although selective strengthening of the infraspinatus muscle is recommended for therapy and training, limited information is available to help clinicians(More)
BACKGROUND To determine the influence of breathing maneuver and sitting posture on tidal volume (TV), respiratory rate (RR), and muscle activity of the inspiratory accessory muscles in patients with chronic obstructive pulmonary disease (COPD). METHODS Twelve men with COPD participated in the study. Inductive respiratory plethysmography and surface(More)
QUESTION Can real-time visual feedback facilitate the activity of serratus anterior in individuals with scapular winging during shoulder flexion? DESIGN Comparative, repeated-measures experimental study. PARTICIPANTS Nineteen subjects with scapular winging. INTERVENTION Participants performed isometric shoulder flexion at 60° and 90° with and without(More)
The effects of passive correction of scapular position (PCSPT) on pain, proprioception, and range of motion (ROM) were investigated in neck-pain patients with bilateral scapular downward-rotation (SDR). Fifteen neck-pain patients with bilateral SDR were recruited from a workplace based work-conditioning center. The intensity of pain felt was quantified(More)
[Purpose] This study investigated the effect of sleep posture on neck muscle activity. [Subjects and Methods] The study recruited 20 healthy subjects, who were positioned in three supine sleeping positions: both hands at sides, both hands on the chest, and dominant hand on the forehead. The activities of the scalene and upper trapezius muscles bilaterally(More)
[Purpose] The purpose of this study was to investigate the relationships among perceived service encounter quality, service value, patient satisfaction, and behavioral intention in physical therapy patients. [Subjects and Methods] This study surveyed 335 patients who received physical therapy treatment at five medical institutions in Jeonju-si, Republic of(More)
OBJECTIVE To investigate the effects of performing an abdominal drawing-in maneuver (ADIM) during active prone knee flexion on the hamstrings and erector spinae muscle activity, the amounts of pelvic motion and knee flexion, and onset of pelvic movements. DESIGN Comparative, repeated-measures study. SETTING University research laboratory. PARTICIPANTS(More)
