Abstract
Objectives
To determine whether the addition of bed exercises after primary total hip replacement (THR) improves functional outcomes and quality of life, in adult patients, during the first six postoperative weeks.
Design
Single-blind randomised controlled trial.
Setting
Inpatient and outpatient orthopaedic departments at a National Health Service hospital.
Participants
Sixty primary elective THR patients.
Intervention
Patients were assigned at random to receive either a standard gait re-education programme and bed exercises, or the standard gait re-education programme without bed exercises after THR. The bed exercises consisted of active ankle dorsiflexion/plantarflexion, active knee flexion, and static quadriceps and gluteal exercises.
Main outcome measures
Iowa Level of Assistance Scale (ILOA), the Short Form-12 Health Survey (SF-12), duration of hospital admission and postoperative complications were assessed at baseline, and 3 days and 6 weeks postoperatively.
Results
There was no statistically significant difference in ILOA scores between the two groups on the third postoperative day [gait re-education and bed exercise group median 40.5, interquartile range (IQR) 17.5 to 44.5; gait re-education alone group median 38, IQR 22.0 to 44.5; P
=0.70]. Although there was a small difference between the median ILOA scores at Week 6 between the two groups (3.5, IQR 0 to 6.4 and 5.0, IQR 3.5 to 12.5; P=0.05), this difference was not statistically or clinically significant. There was no difference between the groups in duration of hospital admission, SF-12 scores or postoperative complications at Week 6.
Conclusion
This study suggests that during the first six postoperative weeks, the addition of bed exercises to a standard gait re-education programme following THR does not significantly improve patient function or quality of life.
