title: Multiple sclerosis: a preliminary study of selected variables affecting rehabilitation outcome.
abstract: OBJECTIVE
  The diversity of physical and cognitive impairments seen in progressive multiple sclerosis (MS), make it difficult to identify the factors that influence neurorehabilitation outcome. Improvements in a motor disability scale must be considered in the context of the patient's physical and cognitive starting points, if the process of neurorehabilitation is to be properly understood.
  
  
  METHODS
  Data was collected from 38 patients (mean age 41 years, 16 men and 22 women) with clinically definite MS (of whom all but one were in the progressive phase of the disease), who were consecutively admitted to a neurorehabilitation unit. Patients' physical disability was assessed on the motor scale of the Functional Independence Measure (FIM) on admission and discharge. Cognitive and neurological assessments were completed on admission. The cognitive battery comprised the WAIS-R, NART, RMT, CVLT CMT, GNT, GDA, and VOSP (some in short form). Emotional measures were the STAI, STAXI and BDI.
  
  
  RESULTS
  The mean improvement on the FIM was 6 points. A multiple regression analysis was performed to determine which cognitive and neurological variables related to reduced disability after neurorehabilitation. To take account of each patient's starting point, the model included their FIM admission score. This variable, together with vocabulary skills and cerebellar function accounted for 57% of the variance in the patients' improvements. These results suggest that verbal intelligence and cerebellar function are influential in determining rehabilitation outcome. Although these findings will be unsurprising to clinicians, this is the first quantitative demonstration of these effects.
