Torso weighting has sometimes been effective for improving upright
mobility in people with multiple sclerosis, but parameters for weighting have
been inconsistent. OBJECTIVE: To determine whether balance-based torso weighting
(BBTW) has immediate effects on upright mobility in people with multiple
sclerosis. METHODS: This was a 2-phase randomized clinical trial. In phase 1, 36
participants were randomly assigned to experimental and control groups. In phase
2, the control group was subsequently randomized into 2 groups with alternate
weight-placement. Tests of upright mobility included: timed up and go (TUG),
sharpened Romberg, 360-degree turns, 25-foot walk, and computerized platform
posturography. Participants were tested at baseline and again with weights placed
according to group membership. In both phases, a physical therapist assessed
balance for the BBTW group and then placed weights to decrease balance loss. In
phase 1, the control group had no weights placed. In phase 2, the alternate
treatment group received standard weight placement of 1.5% body weight. RESULTS:
People with BBTW showed a significant improvement in the 25-foot walk (P = .01)
over those with no weight, and the TUG (P = .01) over those with standard weight
placement. BBTW participants received an average of 0.5 kg, less than 1.5% of any
participant's body weight. CONCLUSION: BBTW can have immediate advantages over a
nonweighted condition for gait velocity and over a standardized weighted
condition for a functional activity in people with multiple sclerosis (MS) who
are ambulatory but have balance and mobility abnormalities.
