The global population is aging, and Taiwan has become an aging society. The aging population continues to rise. When the physical function and mental state of the elderly gradually decline, it is easy for the elderly to enter a state of physical weakness. Weakness is the decline in the reserve capacity of the physiological system. It is also related to geriatric syndrome, causing falls, hospitalization, disability, death, and increased medical costs, burden on primary caregivers, and reduced quality of life for the elderly.

Physical exercise training has been considered to be an effective strategy to prevent and delay disability and frailty, so this study uses the Vivifrail program for the elderly. A family-based 12-week exercise program, including: resistance, strength, balance, flexibility and cardiorespiratory endurance exercise training, performed five days a week, at least 45-60 minutes each time, so that the elderly can exercise at home, It can also improve physical function and improve the quality of life.

This study adopts a randomized controlled trial (RCT) with a one-group pretest-posttest design, with pre-frail and frail elderly as the research objects, and uses comprehensive assessment of the elderly to understand the physical function of the elderly Status, Vivifrail for the elderly was provided for abnormal physical function items, and post-test evaluation was carried out 4 weeks and 12 weeks after the intervention. In Taiwan, there is no research on Vivifrail for the frail elderly. In view of this, it is hoped that through the Vivifrail program and the follow-up of case managers, multi-faceted and continuous integrated care can be provided. Improve and maintain the physical function of the frail elderly for reference in the daily care of the elderly in the future.
