Effect of Comprehensive Behavioral and Exercise Intervention on Physical Function and Activity Participation After...

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Physical Therapy

Background:

• Total knee replacement (TKR) rehabilitation often involves standard exercise programs.
• Optimizing physical function and activity post-TKR is crucial for long-term outcomes.
• A comprehensive behavioral intervention (CBI) combining exercise and education may offer enhanced benefits.

Purpose of the Study:

• To assess the feasibility of a CBI program implemented 3 months post-TKR.
• To compare the effects of CBI versus standard of care exercise (SCE) on physical function and activity.
• To obtain preliminary data on the efficacy of CBI in TKR patients.

Main Methods:

• A 3-month CBI or SCE program followed by a 3-month home exercise program.
• 44 TKR patients were randomized into either CBI or SCE groups.
• Physical function and activity were measured at baseline and 6-month follow-up using validated assessments.

Main Results:

• The CBI program was safe and well-tolerated.
• CBI group showed statistically significant reductions in pain and improvements in physical function compared to SCE.
• Responder analysis indicated higher rates of clinically important improvements in physical function and combined domains for the CBI group.

Conclusions:

• A CBI program is a feasible and effective intervention for improving physical function and activity in patients several months after TKR.
• The findings suggest CBI may be superior to SCE for enhancing recovery post-TKR.
• Larger pragmatic randomized trials are warranted to validate these promising results.
