Physical activity and lifestyle management after joint replacement surgery (PALMS): A feasibility study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To assess the feasibility of a program to increase physical activity as part of lifestyle management after joint replacement surgery (PALMS). Design: This pragmatic pre-post feasibility study included participants referred to community rehabilitation post total hip or knee replacement surgery. Participants attended in-person for 1 h, twice-weekly for six weeks. PALMS consisted of a health screen, including point-of-care testing for metabolic syndrome, a group exercise program based on a cardiac rehabilitation model, and education. Feasibility outcomes were acceptability, demand, implementation and practicality. Secondary exploratory outcomes included physical activity and physical functioning. Results: Forty-six participants (23 men, 23 women), mean age 62 (SD 8) years and a mean of 7 (SD 4) weeks post knee (n = 27) or hip (n = 19) joint replacement surgery were enrolled. PALMS was well accepted by participants and clinicians, was implemented with high rates of adherence (mean 10.4/12 (SD 3.0) sessions attended), and 76% (28 of 37) had metabolic syndrome indicating high demand. However, recruitment did not meet threshold targets of 7 recruits each month (achieved 5.1) and 50% of eligible clients agreeing to participate (achieved 38%). There were no serious adverse events. Post-program, physical activity (mean change 1,678 METS min/wk, 95%CI 997 to 2,359) and physical functioning (6-min walk test mean change 167 m, 95%CI 120 to 215) increased. Conclusion: The PALMS group program was feasible and associated with short-term improvements in physical activity and physical functioning. With attention paid to recruitment strategies the next step is to evaluate program effectiveness with an adequately powered trial.
