Summary
Patients undergoing total joint arthroplasty (TJA) are less active than recommended, averaging 6721 steps daily. Further research needs standardized physical activity assessment in TJA patients.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Sports Science
Background:
- Limited qualitative research exists on physical activity in total joint arthroplasty (TJA) patients.
- Understanding TJA patient activity levels is crucial for post-operative recovery and long-term outcomes.
Purpose of the Study:
- To systematically review instruments used for quantifying physical activity in TJA patients.
- To determine the actual physical activity levels of patients undergoing TJA.
Main Methods:
- Systematic literature review of Medline, Cochrane Library, and EMBASE up to September 2008.
- Included studies assessing physical activity in TJA patients.
- Meta-analysis of data from accelerometers and pedometers.
Main Results:
- 26 studies (2460 patients) were analyzed; motion sensors and questionnaires were common.
- Weighted mean physical activity was 6721 steps/day (95% CI, 5744-7698).
- Activity decreased by 90 steps/day annually with increasing patient age.
Conclusions:
- TJA patients are less active than the recommended 10,000 steps/day for health benefits.
- Their activity levels are higher than typically assumed in simulations.
- Standardization of physical activity assessment and reporting in TJA is needed.
