OBJECTIVE: To describe a progressive resistance training intervention implemented
shortly after total hip arthroplasty, including a detailed description of load
progression, pain response and adverse events to the training. DESIGN: Secondary
analyses of data from the intervention group in a randomized controlled trial.
SUBJECTS: This study reports data from the intervention group ( n = 37).
INTERVENTIONS: The protocol described supervised progressive resistance training
of the operated leg two days/week in addition to home-based exercise five
days/week and for 10 weeks. The relative load progressed from 12 repetition
maximum to 8 repetition maximum during 10 weeks for the exercises: knee
extension, hip abduction, -flexion and -extension. MAIN MEASURES: Training load
in kilograms (kg) for each exercise, hip pain during, before and after exercise
using the Visual Analog Scale and adverse events during the initial four weeks of
training. RESULTS: The majority of patients experienced only moderate hip pain
during exercise (range in median across exercises and sessions: 5-35 mm Visual
Analog Scale) and mild pain at rest (median: 1-18 mm Visual Analog Scale), both
of which decreased over time ( p < 0.001), despite a substantial increase in
absolute training load (67%-166 % across exercises, p < 0.001). Out of 152
training sessions, short term pain response (an increase >20 mm Visual Analog
Scale) occurred in 13 patients in 24 training sessions. CONCLUSION: Progressive
resistance training as described in the present study can be implemented shortly
following total hip arthroplasty with substantial load progression and no overall
exacerbation of postoperative pain. Some patients may experience a short term
pain response. Trial Registration (primary trial): NCT01214954.
