Participant Flow

Potential subjects were identified from their surgeons' office or via public announcement in the greater Pittsburgh area, from December 2014 through February 2017. If interested in the study, subjects called the research team to obtain more information about the study, and were then screened for study eligibility.

A total of 1372 subjects called for study information: 89 could not be contacted and 1283 were screened over the telephone. From those, 1032 were not eligible/willing to participate and 251 completed in-person screening. Eleven subjects failed in-person screening, resulting in 240 eligible subjects that were randomized into one of the study arms.

Measure
Clinic-based Outpatient Exercise Group
Subjects participated in supervised sessions (clinic-based) of exercise followed by a home exercise program 2 times per week during 3 months. Each exercise session lasted about 60 minutes. Treatment sessions utilized a pragmatic approach and included the exercises designed to increase muscular strength, low impact cardiovascular exercise, range of movement, and activity for daily living skills.
Community-based Exercise Group
Subjects attended to exercise classes (community-based) 2 times per week during 3 months. The exercise classes lasted approximately 60 minutes. The group exercise classes consisted of a variety of exercises designed to increase general muscular strength, low impact aerobic exercise, range of movement, and activity for daily living.

SECONDARY outcome

Timeframe: Baseline, 3 and 6 months

Population: Intention-to-treat approach was used among participants with follow-up data.

Scores on 6 performance-based tests (i.e., the 6-minute walk test, 40-meter gait speed, stair ascend/descend test, single leg stance balance test, chair stand test, and floor sitting-rising) were combined into a composite score formed with the unit-weighted Z scores of constituent tests to provide a more representative and stable measure of the subjects' underlying functional performance. The unit weights refer to averaging standardized scores (e.g., the scores for each performance-based test are converted to Z-scores before applying equal weights). Higher Z-scores represent better functional performance. The Z-scores for each participant can be interpreted as deviations from the baseline average of the whole group. We considered a change in Z-score of 0.2 as clinically important because it represents approximately 20% of a standard deviation relative to the baseline average of the whole group.
