Effects of Ving Tsun sticking-hand training on lower limb sensorimotor performance among community-dwelling middle-aged and older adults: a randomized controlled trial

To explore the effects of Ving Tsun (VT) sticking-hand training on knee joint proprioception and leg muscular performance among community-dwelling middle-aged and older adults. Thirty-three middle-aged and older adults were randomly assigned to either the VT or control group. The VT group received sticking-hand training twice/week for 3 months. Data were collected before and after the intervention period. The primary outcome was knee joint repositioning error, which was measured using knee joint active repositioning tests. The secondary outcomes included the maximum muscle strength and time to maximum muscle strength of the major leg muscles. No significant group, time, or group-by-time interaction effects were found for the knee joint repositioning error (p > 0.05). The maximum muscle strength of the knee flexors increased over time in the VT group only (p = 0.038). In addition, the time to maximum muscle strength in the hip extensors and flexors increased over time in both groups (p
