Biofeedback Based Home Balance Training can Improve Balance but Not Gait in People with Multiple Sclerosis

Abstract EN

Background.

Impaired balance is common in people with multiple sclerosis (MS) and can be present even in those with a mild disability level.

With increasing disability, gait, and balance impairment progress, and lead to increased risk of falls.

In some recent studies, interactive commercial video games were used for improving balance, but their limitation is their lack of individual training parameter settings needed for rehabilitation purposes.

The aim of this study was to evaluate the feasibility and effect of balance exercise in the home setting using the rehabilitation Homebalance® system.

Methods.

A single-centre, controlled, single blind study with allocation to intervention group or to control group was utilised.

Participants were assessed at baseline, after four weeks of home-based balance training, and follow-up after four weeks.

The primary outcomes were the Berg Balance Test (BBT).

The secondary outcome measures included the Mini-BESTest, Timed Up, and Go Test (part of Mini-BESTest), and spatio-temporal gait parameter evaluation using the GAITRite instrument.

The patient reported outcomes (PRO) included the 12-Item MS Walking Scale, Activities-specific Balance Confidence Scale, and the Falls Efficacy Scale.

Results.

A total of 39 people with Multiple Sclerosis (10 men) were enrolled into the study.

The mean age of participants was 40.69 ± 10.2 years, with a mean disease duration 14.76 ± 9.1 years and mean disability level 3.8 ± 1.9 EDSS (EDSS range 1.5–7).

Statistically significant improvements within the home exercise group were present for the BBT and the Mini-BESTest.

This improvement was more significant in the subgroup with moderate and higher disability (EDSS 4.5–7).

All other gait parameters and PRO did not show any improvement.

Follow-up assessment after four weeks showed that the reached improvement persisted for a short time period after finishing the regular training regimen.

Conclusion.

In comparison with no intervention, a short-term programme of home-based balance training using Homebalance® improved balance but not gait performance in a group of people with MS.

It seems that home-based balance training tailored according to individual needs by a physiotherapist may be a future approach to consider for telerehabilitation of people with MS.
