OBJECTIVE: To identify the minimal clinically important difference (MCID) to
define clinically meaningful patient's improvement on the Berg Balance Scale
(BBS) in people with multiple sclerosis (PwMS) in response to rehabilitation.
DESIGN: Cohort study. SETTING: Neurorehabilitation institute. PARTICIPANTS: PwMS (N=110).
This study comprised inpatients and outpatients who
participated in research on balance and gait rehabilitation.
All received 20
rehabilitation sessions with different intensities. Inpatients received daily
treatments over a period of 4 weeks, while outpatients received 2 to 3 treatments
per week for 10 weeks. MAIN OUTCOME MEASURES: An anchor-based approach using
clinical global impression of improvement in balance (Activities-specific Balance
Confidence [ABC] Scale) was used to determine the MCID of the BBS. The MCID was
defined as the minimum change in the BBS total score (postintervention -
preintervention) that was needed to perceive at least a 10% improvement on the
ABC Scale. Receiver operating characteristic curves were used to define the
cutoff of the optimal MCID of the BBS discriminating between improved and not
improved subjects. RESULTS: The MCID for change on the BBS was 3 points for the
whole sample, 3 points for the inpatients, and 2 points for the outpatients. The
area under the curve was .65 for the whole sample, .64 for inpatients, and .68
for outpatients. CONCLUSIONS: The MCID for improvement in balance as measured by
the BBS was 3 points, meaning that PwMS are likely to perceive that as a
reproducible and clinically important change in their balance performance.
