introduction: osteoarthritis (oa) is a common degenerative joint disease particularly in older subjects. it is usually associated with pain, restricted range of motion, muscle weakness, difficulties in daily living activities and impaired quality of life. to determine the effects of adding two different intensities of low-level laser therapy (lllt) to exercise training program on pain severity,...

Both electrical stimulation and electromyographic biofeedback have been shown to be more effective than voluntary isometric exercise alone in the recovery of quadriceps femoris muscle force following anterior cruciate ligament (ACL) reconstruction. In a comparison of these two modalities, 30 patients with ACL reconstruction were randomly assigned to either a group receiving electrical stimulati...

[Purpose] The purpose of this study was to investigate the effect of isometric hip adduction and abduction on trunk muscle activity during plank exercises. [Subjects and Methods] Nineteen healthy male subjects were recruited for this study. All subjects performed the traditional plank exercise (TP), plank exercise with isometric hip adduction (PHAD), and plank exercise with isometric hip abduct...

The purpose of this study was to compare the effectiveness of both high volt galvanic current (HVG) and isometric exercise to strengthen the quadriceps femoris muscles in 17 healthy subjects. The subjects were divided into three groups. The Control Group (n = 6) received no exercise or stimulation. The Isometric Exercise Group (n = 5) performed 15 sessions of maximum isometric contractions, and...

The effects of supine isometric handgrip and graded isotonic bicycle ergometer exercise on left ventricular performance were studied echocardiographically in 20 normal subjects, aged 18 to 36. Measurements of the left ventricular minor axis diameter were taken from recordings performed at rest, during each form of exercise, and during recovery. At the completion of isometric exercise, the press...

OBJECTIVE The purpose of this study was to identify exercise protocols incorporating isometric contractions that provide pain relief in women with fibromyalgia. DESIGN A before-after trial. SETTING A physical therapy department in an academic setting. PARTICIPANTS Fifteen women (mean ± SD, 52±11y) with fibromyalgia. INTERVENTIONS Subjects completed 4 sessions: 1 familiarization and 3 ex...

Four subjects, whose ages averaged 24.3 years, were examined to assess the isometric component of dynamic exercise during the following 4 conditions: treadmill running, cycle ergometry, aerobic exercise following a video, and during hip extension exercise (lunges). The isometric component of exercise was characterized by examining heart rate (HR) and blood pressure (BP), muscle fatigue, oxygen ...
