Objectives

Whilst gait speed is variable between healthy and injured adults, the extent to which speed alone alters the 3D in vivo knee kinematics has not been fully described. The purpose of this prospective study was to understand better the spatiotemporal and 3D knee kinematic changes induced by slow compared with normal self-selected walking speeds within young healthy adults.

Methods

A total of 26 men and 25 women (18 to 35 years old) participated in this study. Participants walked on a treadmill with the KneeKG system at a slow imposed speed (2 km/hr) for three trials, then at a self-selected comfortable walking speed for another three trials. Paired t-tests, Wilcoxon signed-rank tests, Mann-Whitney U tests and Spearman’s rank correlation coefficients were conducted using Stata/IC 14 to compare kinematics of slow versus self-selected walking speed.

This paper reports a prospective study of 72 consecutive patients with fractures or fracture-dislocations of the upper end of the humerus, treated during 1981. Most were elderly and treatment was conservative. Of the 72 patients 64 were followed up for a period of six months. Observations were made on the type of fracture, the speed and pattern of recovery of shoulder movements, on the time of commencement of physiotherapy, and on its duration. We found that with conservative treatment alone, 94% of our patients had good or satisfactory results at six months from injury. The criteria for manipulation are discussed and the literature is reviewed.
