AIM Lately, the diagnostic value of magnetic resonance imaging, Lasègue sign and classic neurological signs have been considered not accurate enough to distinguish the radicular from non-radicular low back with leg pain (LBLP) and a calculation of the symptomatic side muscle volume has been indicated as a probable valuable marker. However, only the multifidus muscle volume has been calculated s...

Intact abductors of the hip play a crucial role in preventing limping and are known to be damaged through the direct lateral approach. The extent of trauma to the abductors after revision total hip replacement (THR) is unknown. The aim of this prospective study was to compare the pre- and post-operative status of the gluteus medius muscle after revision THR. We prospectively compared changes in...

[Purpose] The present study examined the activity and the gait characteristics of the gluteus medius and the trunk stability muscles during the stance phase of gait on level ground when a vertical load corresponding to 0%, 1%, or 2% of body weight was placed on the lower extremities during the swing phase of the gait. [Methods] The subjects were 40 young males aged between 21 and 30 years. The ...

[Purpose] We investigated the effects of shoulder flexion loaded by an elastic tubing band during squat exercises, by assessing electromyographic activities of the gluteus maximus and gluteus medius. [Subjects] In total, 17 healthy males were recruited. [Methods] Participants performed squat exercises with and without shoulder flexion loaded by a tubing band. Gluteal muscle activities during th...

One hundred beef carcasses were selected at three packing plants and were used to determine the relationship between glycolytic potential (GP) and dark, firm, and dry (DFD) beef and to determine the effects of DFD status and GP on cooked beef palatability. Eight individual muscles were excised from one hindquarter of each carcass at d 7 postmortem: longissimus lumborum, psoas major, gluteus med...

STUDY DESIGN Case report. BACKGROUND The underlying mechanism of the changes in running mechanics after gait retraining is presently unknown. This case report assesses changes in muscle coordination and kinematics during treadmill running and step ascent in 2 female runners with patellofemoral pain after mirror gait retraining. CASE DESCRIPTION Two female runners with chronic patellofemoral...

CONTEXT Reduced strength and activation of hip muscles might correlate with increased weight-bearing knee valgus. OBJECTIVE To describe relationships among frontal-plane hip and knee angles, hip-muscle strength, and electromyographic (EMG) recruitment in women during a step-down. DESIGN Exploratory study. SETTING Laboratory. PARTICIPANTS 20 healthy women 20 to 30 years of age. INTERVE...

[Purpose] This study used an alternative approach compared with previous studies by investigating the effect of minimizing arm swing while walking on the trunk and gluteal muscles. [Subjects and Methods] The subjects of this study included 13 adult males. [Results] The latissimus dorsi muscle activities during walking with a minimized arm swing were significantly decreased compared with those d...

Purpose: This study was accomplished to investigate the electromyographic activity of 3 plyometric exercises (tuck jump and single leg hop in sagittal and frontal planes) to find out the appropriate procedures for strengthening biceps femoris and gluteus medius muscles. Methods: The kind of study is applied and data were collected from the supervised exercises of 15 male athletes without i...
