Dt. Kenny, Exercise-based rehabilitation for injured workers: programme efficacy and identification of factors predicting programme completion and outcome, INT J REHAB, 23(1), 2000, pp. 7-17
A sample of 355 injured workers presenting to a tertiary referral agency fo
r supervised physical activity programmes were assessed for programme compl
etion and changes in work status at the conclusion of the programme. Sevent
y-five percent of the sample comprised long-term (i.e. greater than six mon
ths) injured workers, of whom 45% were unemployed at the commencement of th
e programme. There was a 15% dropout rate and 49% of completers improved th
eir work status at the end of the programme. A series of stepwise logistic
regression analyses were conducted to identify predictors of dropout and im
proved work status. Joint pathology was the only predictor of dropout. Prep
rogramme work status, referral source, intervertebral pathology, and time b
etween injury and commencement of the programme predicted post-programme wo
rk status. Those workers who were employed, referred by sources other than
rehabilitation providers, such as doctors, employers or insurers, did not h
ave a diagnosis including intervertebral pathology and who began their prog
rammes within six months of injury were more likely to improve their work s
tatus at the conclusion of the programme. Other factors including age, gend
er, occupation, insurer category, location of injury (i.e. lumbar or other)
, and neurological signs predicted neither programme completion nor change
in work status.
