Objectives:
We examined the rate of functional change (using performance measures and a self-report questionnaire) during interdisciplinary occupational rehabilitation in workers' compensation claimants with a variety of musculoskeletal conditions. We also estimated the rate of improvement that could be considered clinically important and examined factors associated with rate of functional improvement.
Methods:
A prospective cohort design was used, with data collected before and after claimants participated in an interdisciplinary occupational rehabilitation program. A consecutive sample was formed of claimants admitted between July 2005 and June 2007. Measures included performance-based functional measures (functional capacity evaluation, FCE) and a self-report questionnaire (pain disability index, PDI).
Results:
The sample included 582 compensation claimants with a variety of musculoskeletal conditions. The majority of claimants experienced functional improvement during rehabilitation. Claimants with the outcome status 'Return-to-Work Pre-accident' had the highest rate of functional change (up to 5 kg/week on floor to waist lifting, ~7 points/week on the PDI).
Conclusion:
The clinically important rate of functional change appears to be 5 kg/week on FCE floor-to-waist lifting and 7 points/week on the PDI (scored out of 100). Rate of functional change appears to be multifactorial, with a variety of physical, demographic, clinical, and environmental factors explaining rate of change.
