BackgroundIn-hospital progressive resistance training PRT has been shown to be an effective method of rehabilitation following hip surgery. The aim of this study was to assess whether a home-based PRT program would be beneficial in improving patients’ muscle strength and physical function compared to standard rehabilitation.

MethodsSubjects n = 49 either received home-based PRT rehabilitation n = 25 or standard rehabilitation n = 24 in a prospective single blinded randomized trial carried out over a two-year period. The primary outcome measure was the maximal voluntary contraction of the operated leg quadriceps MVCOLQ with secondary measures of outcome being the sit to stand score ST, timed up and go TUG, stair climb performance SCP, the 6 min walk test 6MWT, and lean mass of the operated leg LM.

ResultsTwenty-six patients completed follow up at 1 year n = 13 per group for the final comparative analysis. All the outcome measures showed marked progressive improvements from the baseline measures at 9–12 months post op Estimated effect std error; p value- MVCOLQ 26.50 8.71 N p = 0.001; ST 1.37 0.33 p = 0.0001; TUG −1.44 0.45 s p =0.0001; SCP −3.410.80s p = 0.0001; 6MWT 45.61 6.10m p = 0.0001; LM 20 204g p = 0.326 following surgery for both groups. Overall, there was no significant effect for participation in the exercise regime compared with standard care for all outcomes assessed.

ConclusionsOverall, this study demonstrated that there is no significant difference between the two groups for participation in the home-based PRT exercise programme when compared to standard care for all outcomes.
