Combating Hospital-related Function Decline Among Prefrail Older Adults: Pilot Testing of a Strength-based Tailored-Exercise Program at Home (STEP@Home)

STEP@Home is a multi-component exercise program designed for prefrail older adults that incorporates active strategies to promote long-term engagement. The optimal level of training is 45-60 minutes of exercise three times per week for at least 20 weeks. For prefrailty management, emphasis is placed on balancing and resistance training (around 15-20 min each) to improve muscle strength and gross mobility and prevent falls. Aerobic and flexibility exercises (10 min each) are also included to improve fitness and walking pace. Sixteen training tasks, including but not limited to those recommended by Vivifrail, for each exercise component (namely, resistance, balance, flexibility and aerobic training) will be adopted. A training manual with step-by-step illustrations of each task in pictures and text will be provided to the subjects, together with a set of simple, easy-to-access equipment (water bottle, elastic band and weight-bearing belt) to support task fulfilment.

Usual Care Activities will be provided by the elderly community center such as dementia or caregiver supporting service. They will be allowed to use the regular service provided such services are not related to physical activity or exercise training.
