Trial Outcomes & Findings for Lokomat Versus Strength Training in Chronic Incomplete Spinal Cord Injury (NCT NCT01087918)

NCT ID: NCT01087918

Last Updated: 2012-10-29

Results Overview

The 10 meter walk test assesses the time required to walk 10 meters at the patient's preferred speed (in seconds). Results were converted to walking speed \[m/s\]. Displayed are values after each intervention (RAGT or strength training) minus value at baseline. Positive values denote improvements.

PRIMARY outcome

Timeframe: Baseline, after intervention (4 weeks)

The 10 meter walk test assesses the time required to walk 10 meters at the patient's preferred speed (in seconds). Results were converted to walking speed \[m/s\]. Displayed are values after each intervention (RAGT or strength training) minus value at baseline. Positive values denote improvements.

The WISCI II describes whether a patients requires waling aids, braces or personal assistance to walk 10 meters. It is an ordinal scale varying from 0 (= not able to walk 10 meters) to 20 (= able to walk 10 meters with no walking aids, braces or personal assistance). Displayed are values after each intervention (RAGT or strength training) minus value at baseline. Positive values denote improvements.

With the manual muscle test, we examined strength of the lower extremities. Five key muscles on each side are evaluated from 0 (= total paralysis) to 5 (= normal strength). Values for left and right were then averaged. Displayed are values after each intervention (RAGT or strength training) minus value at baseline. Positive values denote improvements.
