Abstract:The English Rivermead Mobility Index (RMI) has been proposed as a simple, valid and reliable measure in stroke rehabilitation. A German version was established and validated in two centres. In centre A 46 acute (median: 3.0 days after onset) and in centre B 151 chronic (median: 88.0 days after onset) stroke patients participated. Interrater reliability of the German RMI was tested in 12 subjects in the acute stage of stroke and was found to be statistically significant (r = 0.98, P < 0.0001). In centre A, a statistically significant correlation was found between the German RMI and the 10-m walk time at baseline (r = 0.73, P < 0.0001) and after three weeks (r = 0.92, P < 0.0001). In centre B, the German RMI correlated significantly with the motor part of the Functional Independence Measure (motor-FIM) on admission (r = 0.78, P < 0.0001) and after three weeks (r = 0.79, P < 0.0001), respectively. The change of the RMI correlated significantly with the change in 10-m walk time in acute patients (r = 0.87, P < 0.0001) and with the change in motor-FIM in chronic patients (r = 0.54, P < 0.0001). A moderate ceiling-effect was detected in the chronic study population. The German RMI appears to be a reliable, valid and responsive measure for mobility disability in acute and chronic stroke patients.
