Conditions

Frailty in community dwelling older adults

Interventions

The intervention group (n=8) participated in a 6-month community-based voluntary multicomponent frailty prevention exercise program jointly developed by physical and occupational therapists. The progr
daily routines at home and in the community. The program consisted of seven exercise components: (1) stretching
(2) low-intensity resistance training using 500g water bottles
(3) dual-task exercises
(4) sit-to-stand movements
(6) stair climbing
and (7) hill walking. The control group (non-intervention group
n=6) continued their usual daily activities during the study period and received no structured exercise program as part of the study.
