OBJECTIVE The purpose of this study was to investigate the effect of hip adduction on the activity of the Vastus Medialis Obliquus (VMO) and Vastus Lateralis Longus (VLL) muscles during semisquat exercises. METHODS Twenty female subjects, divided into two groups comprising healthy and patellofemoral pain syndrome (PFPS) subjects (ten volunteers for each group), performed three double-leg semi...

Aging leads to a decline in strength and an associated loss of independence. The authors examined changes in muscle volume, maximum isometric joint moment, functional strength, and 1-repetition maximum (1RM) after resistance training (RT) in the upper extremity of older adults. They evaluated isometric joint moment and muscle volume as predictors of functional strength. Sixteen healthy older ad...

BACKGROUND In patients with chronic tension-type headache (CTTH) changes in pressure pain in the cervical region are associated with peripheral or central sensitization. It is hypothesized that an increase of isometric strength of neck flexors would lead to a decrease of pressure pain in CTTH, as an expression of reduced peripheral or central sensitization OBJECTIVE In this study we aimed to ...

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...

BACKGROUND The purpose of this study was to investigate the lifting characteristics of elders with functional limitations using burden lifting smoothness, trunk angular momentum, and back and hip torque, and to correlate these characteristics with strength and functional measures. METHODS Thirty elders (65-89 years old) consented to biomechanical analysis of lifting, gait, and chair rise, and...

The presence of severe dynamic knee valgus in asymptomatic women may be a factor related to future complaints pain this joint. aim study is correlate the strength levels hip and trunk stabilizer muscles with angles, pelvic tilt young women. 22 no history lower limb or injury participated study. In first visit laboratory, volunteers performed anamnesis, kinematic evaluation angle, tilt. Afterwar...

OBJECTIVE To determine if the combined isometric contractions of knee extension/hip adduction and knee extension/hip abduction will elicit a different quadriceps and gluteus medius electromyographic (EMG) pattern as compared to isometric contraction of a uniplanar knee extension exercise. METHODS Eight healthy young adult volunteers without history of knee or quadriceps injury participated. S...

OBJECTIVE To examine the test-retest reliability and construct validity of cervical active range of motion and isometric neck muscle strength as measured by the Multi Cervical Rehabilitation Unit (Hanoun Medical Inc., Ontario). DESIGN A cross-sectional study. SETTING Institutional practice. SUBJECTS Twenty-one patients with neck pain and 25 healthy volunteers. METHODS After a trial-run ...

PURPOSE To determine the impact of multipurpose exercise training on bone, body composition, blood lipids, physical fitness, and menopausal symptoms in early postmenopausal women with osteopenia. METHODS Forty-eight fully compliant (more than two sessions per week for 38 months) women (55.1 +/- 3.3 yr) without any medication or illness affecting bone metabolism took part in the exercise train...
