Electrodiagnosis of cervical radiculopathy.

Cervical radiculopathy is a common diagnosis with a peak onset in the fifth decade. The most commonly affected nerve root is C7, C6, and C8. The etiology is often compressive, but may arise from noncompressive sources.

The kinematics and kinetics of turning: limb asymmetries associated with walking a circular path.

The biomechanics of changing direction while walking has been largely neglected despite its obvious relevancy to functional mobility. The world is filled with turns that must be negotiated. These turns carry an increased risk of injury due to a decrease in stability.

Break-technique handheld dynamometry: relation between angular velocity and strength measurements.

Objectives: To determine whether the muscle strength, as measured with break-technique handheld dynamometry (HHD), is dependent on the angular velocity achieved during testing and to compare reliability at different angular velocities.

Design: Repeated-measures study. Participants underwent HHD by using make-technique (isometric) and break-technique (eccentric) dynamometry at 3 prespecified angular velocities.

Pigmented villonodular synovitis: an uncommon presentation of anterior hip pain.

Pigmented villonodular synovitis (PVNS) is a rare, benign, idiopathic proliferative disorder of the synovium that results in villous or nodular formation in joints, tendon sheaths, and bursae. The disease can be localized or diffuse. Its estimated prevalence is 1.
