The aim of this study was to investigate the effects of high-velocity
(HV) and low-velocity (LV) resistance training on gait kinematics and kinetics in
patients with hip osteoarthritis. DESIGN: This was a single-blind, randomized
controlled trial. Forty-six women with hip osteoarthritis were randomly allocated
to the HV (n = 23) or LV (n = 23) training group. The participants underwent an
8-week home-based the HV or LV resistance-training program, involving the hip and
knee muscles. Outcome measures included gait kinematics and kinetics using
3-dimensional analyses, muscle strength and power, the Harris Hip Score, and hip
pain using the visual analog scale. RESULTS: There was no significant difference
in changes for any of the outcome measures between groups. After the training
session, muscle power, walking speed, and cadence significantly increased only in
the HV group, whereas stride length and the peak hip extension angle during gait
significantly increased, and pain on the visual analog scale and the peak ankle
dorsiflexion moment during gait significantly decreased only in the LV group.
Muscle strength and Harris Hip Score significantly increased in both groups.
CONCLUSIONS: The results of this study may indicate that the potential effect of
resistance training on abnormal gait pattern depends on movement velocities
during training.
