OBJECTIVE: To determine how much moderate-intensity physical activity, in the
form of walking, could be prescribed for people living in the community after hip
fracture in terms of safety, tolerability, and feasibility. DESIGN: Phase I
dose-response design. SETTING: Public community rehabilitation centers.
PARTICIPANTS: Community-dwelling adults (N=21; 16 women; mean age, 75+/-9y) who
were cognitively alert, attending community rehabilitation after hip fracture
(mean days postfracture, 110+/-47d), able to walk with or without a gait aid, and
for whom it was safe to participate in physical activity. INTERVENTIONS:
Individually supervised doses of moderate-intensity walking completed in 1 week
in addition to their usual levels of physical activity. Three participants were
required to complete a dose of walking before dose escalation for the next cohort
of 3 participants. Dose escalation ceased when >1 participant in a cohort had an
adverse event or was unable to tolerate the dose or if the maximum dose of
150min/wk was achieved. MAIN OUTCOME MEASURES: Maximum tolerated dose of walking
per week (in minutes), adverse events, mobility, and walking confidence. RESULTS:
The maximum tolerated dose of walking for adults after hip fracture before
significant discomfort was experienced (eg, breathlessness, pain, and fatigue) by
any participant was 100min/wk. No adverse events occurred, but participants began
to be unable to tolerate higher doses beyond 100min/wk. CONCLUSIONS: This
provides preliminary evidence that community-dwelling older adults recovering
from hip fracture can complete a sufficient amount of moderate-intensity physical
activity to maintain and improve their health.
