No difference in gait between posterior cruciate retention and the posterior stabilized design after total knee arthroplasty.

Purpose: In the present study, knee joint kinematics (e.g. knee flexion/extension) and kinetics (e.

Gait adjustments in obstacle crossing, gait initiation and gait termination after a recent lower limb amputation.

Objective: To describe the adjustments in gait characteristics of obstacle crossing, gait initiation and gait termination that occur in subjects with a recent lower limb amputation during the rehabilitation process.

Design: Prospective and descriptive study.

Subjects: Fourteen subjects with a recent transfemoral, knee disarticulation or transtibial amputation.

Comparative roll-over analysis of prosthetic feet.

A prosthetic foot is a key element of a prosthetic leg, literally forming the basis for a stable and efficient amputee gait. We determined the roll-over characteristics of a broad range of prosthetic feet and examined the effect of a variety of shoes on these characteristics. The body weight of a person acting on a prosthetic foot during roll-over was emulated by means of an inverted pendulum-like apparatus.

Controlling propulsive forces in gait initiation in transfemoral amputees.

During prosthetic gait initiation, transfemoral (TF) amputees control the spatial and temporal parameters that modulate the propulsive forces, the positions of the center of pressure (CoP), and the center of mass (CoM). Whether their sound leg or the prosthetic leg is leading, the TF amputees reach the same end velocity. We wondered how the CoM velocity build up is influenced by the differences in propulsive components in the legs and how the trajectory of the CoP differs from the CoP trajectory in able bodied (AB) subjects.

Reliability of popliteal angle measurement: a study in cerebral palsy patients and healthy controls.

Unlabelled: The popliteal angle is a widely used clinical measure for hamstring contracture in cerebral palsy (CP) patients and in healthy individuals. The reliability of popliteal angle measurement is being questioned. The aim of this study is to determine the reliability of popliteal angle measurement by means of visual and goniometric assessment.

A preliminary study on electromyographic analysis of the paraspinal musculature in idiopathic scoliosis.

The paraspinal muscles have been implicated as a major causative factor in the progression of idiopathic scoliosis. Therefore, the objectives of this preliminary study were to measure the electromyographic activity (EMG) of the paraspinal muscles to determine its relationship to progression of the scoliotic curve. Idiopathic scoliotic patients were selected and identified afterwards on curve progression.

The relation between electromyography and growth velocity of the spine in the evaluation of curve progression in idiopathic scoliosis.

Study Design: A prospective study in which patients with idiopathic scoliosis were examined longitudinally by radiographic and electromyographic measurements according to a protocol.

Objectives: To measure the growth velocity of the spine and the electromyographic ratio of the paraspinal muscles to determine their relation to progression of the scoliotic curve.

Summary Of Background Data: Several factors have been reported to be involved in the progression of idiopathic scoliosis.

Gait and function in patients with a femoral endoprosthesis after tumor resection: 18 patients evaluated 12 years after surgery.

We performed gait analysis in 18 patients with a femoral endoprosthesis: 12 distal, 3 proximal and 3 total. Follow-up after surgery was mean 12 (0.6-19) years.
