Inpatient Rehabilitation is Effective for Severe Daily Activity Deficits Related to Chronic Low Back Pain.

Abstract

Background and objective: Chronic low back pain disability (CLBPD) is a syndrome that includes pain, disability, emotional impairments, and social problems. The study was conducted to examine the effect of an inpatient rehabilitation program on the performance of everyday life tasks (daily activities), and report on pain in CLBPD patients with primary activities of daily living (ADL) deficits.

Methods: In a retrospective cohort study, demographic and clinical data were retrieved from records of inpatients admitted consecutively to the program. Scores of the Spinal Pain Independence Measure (SPIM) and of changes in reported pain levels were used to assess improvement in the performance of daily activities and pain reduction. T-tests were used to assess the significance of score changes. Spearman's correlations and analysis of variance were used to assess relationships of SPIM gain and affecting factors.

Results: Ninety-nine patients were included. Daily task performance improved in 71 patients (71.7%). The SPIM score increased from 48.7 (SD 16.3) at admission to the rehabilitation program to 57.8 (SD 12.5) at discharge (P<0.001). The SPIM score at admission negatively affected SPIM gain (P<0.001). The SPIM gain was significant for admission SPIM scores of 50 or lower (P<0.05), but differences in SPIM scores were not as noticeable for patients with admission SPIM scores above 50. Relief in pain was reported in 59 patients (59.6%) and was not associated with function.

Conclusions: The multidisciplinary rehabilitation program, which improved function and provided limited pain relief in inpatients with CLBPD primary ADL deficits, can be effective for the most severe CLBPD cases.
