Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypothesis: The VT group subjects will have improved post-training reactive balance control, muscle strength, balance confidence and fall incidence outcomes than the active controls.
Design and subjects: In this prospective, randomised, single-blinded controlled trial, approximately 114 healthy seniors (55-70 years old) will be randomly assigned to either the VT group (n\~57) or control group (n\~57). Interventions: Subjects in the VT group will receive VT reactive balance training (3 hours/week) for 3 months, whereas subjects in the control group will receive no VT training but will jog 3 hours/week during the intervention period.
Study instruments and outcomes: Primary outcome measures: reactive balance control, as indicated by lower extremity muscle activation onset latency; hip and ankle strategies and centre of pressure movements will be measured by electromyography, electrogoniometry and a force platform, respectively. Secondary outcome measures: knee muscle strength, balance confidence and fall history will be assessed by an isokinetic dynamometer, Activities-specific Balance Confidence Scale (Chinese) and interviews, respectively (pre-, post- and follow-up measurements).
Data analysis: Data will be analysed using repeated-measures analysis of (co)variance followed by post-hoc tests, as appropriate (alpha = 0.05).
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To evaluate the effects of a Ving Tsun (VT) martial exercise programme on reactive balance control, lower limb muscle strength, balance confidence and falls in community-dwelling older adults.
Study design:
This will be a prospective, non-randomised and controlled intervention trial.
Subjects:
Approximately 40 healthy older adults will be recruited from elderly community centres by convenience sampling through poster advertising. Eligible subjects will be allocated to either the VT group (n ≈ 20) or control group (n ≈ 20).
Outcome measurements:
All subjects will be assessed before the intervention (baseline tests) and shortly after the 3-month intervention (post-tests). All subjects, regardless of group assignment, will undergo the following baseline tests and post-tests in random order.
Primary outcome measures Reactive balance control including lower extremity muscle activation onset latency and centre of pressure movement in standing.
Secondary outcome measures Lower extremity (knee) muscle strength, balance confidence and fall history.
Data analysis:
Data will be analysed using repeated-measures analysis of (co)variance followed by post-hoc tests, as appropriate (alpha = 0.05).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ving Tsun (VT) group
Participants in the VT group will receive VT exercise intervention for 12 weeks.
Ving Tsun
The VT training regimen is designed to improve reactive balance control, lower extremity muscle strength and balance confidence in the elderly. It comprises 9 VT sticking-hand drills that must be practised with a partner. Participants will be trained to respond rapidly to upper body perturbations and to maintain body balance. Those joined the VT training group will attend a one-hour supervised VT training session at an elderly community centre 2 times per week for 12 weeks.
Control group
No intervention but can continue daily activities.
