Excessive flexion and internal rotation of the hip is a common gait abnormality among individuals with cerebral palsy. The purpose of this study was to examine the influence of hip flexion on the rotational moment arms of the hip muscles. We hypothesized that flexion of the hip would increase internal rotation moment arms and decrease external rotation moment arms of the primary hip rotators. T...

uncontrolled recurrent hemarthrosis can end to contracture, deformity, pain, joint destruction and gait disorders which are disabling. we are going to report a challenge, a unilateral knee flexion contracture in a child with severe hemophilia a and inhibitor who underwent different treatment options with unsatisfactory improvement of knee range of motion. mismanaging postoperatively, patient an...

[Purpose] The job of secondary school teachers involves a lot of head down posture as frequent reading, assignment correction, computer use and writing on a board put them at risk of developing occupational related neck pain. Available studies of neck pain experienced by teachers are limited. The purpose of this study was to determine whether training of deep cervical flexor muscles with pressu...

BACKGROUND Occupational computer use has been associated with upper extremity musculoskeletal disorders (UEMSDs), but the etiology and pathophysiology of some of these disorders are poorly understood. Various theories attribute the symptoms to biomechanical and/or psychosocial stressors. The results of several clinical studies suggest that elevated antagonist muscle tension may be a biomechanic...

PURPOSE This study aimed to evaluate the kinematics of the flexor pollicis longus tendon (FPL) at the wrist by examining the movement of the FPL on the distal radius during various wrist and finger motions using transverse ultrasound in healthy volunteers. METHODS Forty-eight wrists of 24 asymptomatic volunteers were examined by transverse ultrasound to observe the location of the FPL on the ...

PURPOSE To measure preoperative hip flexion under general anaesthesia in patients with developmental dysplasia of the hip and analyse its correlation with leg-length change. METHODS 79 women and 6 men aged 27 to 82 (mean, 59) years underwent 92 total hip arthroplasties for severe developmental dysplasia of the hip of Crowe types II (n=60), III (n=17), and IV (n=15). All such patients had seve...

BACKGROUND Studies of medial and lateral femoral posterior condylar offset have disagreed on whether posterior condylar offset affects maximum knee flexion angle after TKA. QUESTIONS/PURPOSES We asked whether posterior condylar offset was correlated with knee flexion angle 1 year after surgery in (1) a PCL-retaining meniscal-bearing TKA implant, or in (2) a PCL-substituting mobile-bearing TKA...
