Background:
Total hip replacement (THR) results in pain reduction and func-
tional improvements. However, it is suggested that these improvements are
not followed by increases in physical activity level and return to usual activities
postoperatively. Furthermore, it is unknown whether supervised rehabilitation
affects the activity level as well as return to work after THR.
Purpose / Aim of Study:
To investigate whether supervised progressive resis-
tance training during the first 10 weeks after THR affects the change in physical
activity level from baseline to 6 months after THR and early return to work.
Materials and Methods:
73 THR patients were randomly assigned to a con-
trol group (CG, home based exercise) or intervention group (IG, supervised re-
sistance training in addition to home based exercise). Preoperative, 6 and 12
months postoperative self-reported physical activity was measured in meta-
bolic equivalents (METS) with the Physical Activity Scale (PAS) and days until
return to work.
Findings / Results:
Follow up was completed by 62 patients (85%). Changes in
PAS scores from baseline to 6 months follow up were, mean [95% CI]: IG: 6.32
[3.5;9.1] METS and CG: 0.85 [-2.8;4.5] METS (p=0.02). Sick leave duration
in the working population of the sample (n=25) were, median [range]: IG: 46
[6;161] days and CG: 57 [7;146] days (p=0.49).
Conclusions:
Patients performing supervised resistance training in addition to
home-based exercise increased their self-reported physical activity level more
than patients performing home-based exercise only, during 6 months after THR
however, the difference was eliminated at 1 year follow up. No significant dif-
ference was found concerning return to work.
