OBJECTIVE: To investigate the postoperative efficacy of a supervised programme of neuromuscular exercise prior to hip or knee arthroplasty.

METHODS: In this assessor-blinded randomised controlled trial, we included 165 patients scheduled for hip or knee arthroplasty due to severe osteoarthritis (OA). An 8-week preoperative neuromuscular supervised exercise programme was delivered twice a week for 1 h as adjunct treatment to the standard arthroplasty procedure and compared with the standard arthroplasty procedure alone. The primary outcome was self-reported physical function measured on the activities of daily living (ADL) subscale in the Hip disability and Osteoarthritis Outcome Score (HOOS) and the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaires for patients with hip and knee OA, respectively. Primary endpoint was 3 months after surgery.

RESULTS: 165 patients randomised to the two groups were on average 67±8 years, 84 (51%) had hip OA and 92 (56%) were women. 153 patients (93%) underwent planned surgery and were evaluated postoperatively. There was no statistically significant difference in effects between hip or knee patients (p=0.7370). Three months postoperatively, no difference was found between groups for ADL (4.4, 95% CI -0.8 to 9.5) or pain (4.5, 95% CI -0.8 to 9.9). However, there was a statistically significant difference indicating an effect of exercise over the entire period (baseline to 3-months postoperatively) (p=0.0029).

CONCLUSIONS: Eight weeks of supervised neuromuscular exercise prior to total joint arthroplasty (TJA) of the hip or knee did not confer additional benefits 3 months postoperatively compared with TJA alone. However, the intervention group experienced a statistically significant short-term benefit in ADL and pain, suggesting an earlier onset of postoperative recovery.

AIMS: The Satisfaction with Daily Occupations (SDO) scale assesses satisfaction within the domains of work, leisure, domestic tasks, and self-care. The aim was to investigate the psychometric properties of the Danish version of the SDO when used with asylum seekers.

METHODS: The participants were 93 Danes without known ill health and 43 asylum seekers. They completed the SDO and rated their perceived health, activity level, and general satisfaction with daily occupations. Translation into Danish and back-translation into Swedish was made by professional interpreters.

RESULTS: Internal consistency was α = 0.75 for the Danish sample and α = 0.79 for the asylum seekers. The SDO distinguished between asylum seekers and the Danish sample, suggesting criterion validity. Concurrent validity, analysed against general satisfaction with daily occupations, was indicated for both samples. Discriminant validity was indicated against self-rated health for both samples and against activity level for the Danish sample. There was, however, a correlation of 0.65 between the SDO satisfaction score and activity level for the asylum seekers.

CONCLUSION: The SDO exhibited satisfactory internal consistency and criterion and concurrent validity. The findings regarding discriminant validity were somewhat inconclusive. The Danish SDO may be regarded as psychometrically sound but further psychometric testing is needed.
