Exercise in knee osteoarthritis – preliminary findings: Exercise-induced pain and health status differs between drop-outs and retainers
38 knee osteoarthritis patients started a 18 weeks walking or strengthening program
6 patients dropped out
Comorbidities did not correlate with adherence or compliance
Higher dropout rate was observed for worse baseline health status
Drop-outs had higher exercise-induced pain than retainers
Exercise effectiveness is related to adherence, compliance and drop-out. The aim of this study is to investigate if exercise-induced pain and health status are related to these outcomes during two exercise programmes in knee osteoarthritis patients.
Symptomatic knee osteoarthritis patients were randomly allocated to a walking or strengthening programme (N = 19/group). At baseline, patients were categorized according to their health status. Exercise adherence and compliance were calculated and drop-out rate was registered. For exercise-induced pain, patients rated their pain on an 11-point numeric rating scale (NRS) before and after each training session. Before each session the maximal perceived pain of the last 24 h (NRSmax24) was assessed. Patients rated their global self-perceived effect (GPE) on a 7-point ordinal scale after the intervention period.
53% of the participants felt they improved after the programme, 6 patients dropped out. The mean adherence and compliance rates were higher than .83 in both groups. Worse health and higher exercise-induced pain were seen in drop-outs. NRSmax24 during the first 3 weeks did not significantly increase compared to baseline, but correlated negatively with adherence during the home sessions (−.56, p < .05). Lower adherence during supervised sessions was significantly related with higher pre-exercise pain scores (ρ = −.35, p < .05).
Patients who drop-out show a worse health condition and higher exercise-induced pain levels compared to patients that retained the programme.
