Effects of dynamic balance training during standing and stepping in patients with hereditary sensory motor neuropathy

Purpose. To quantitatively evaluate the effects of dynamic balance training in patients with hereditary sensory motor neuropathy (HSMN). Methods. Sixteen patients with HSMN were randomly assigned to either an experimental or control group. The intervention session consisted of passive stretching, muscle strengthening and dynamic balance training during standing and stepping, which differed in that the experimental group used commercially available balance training mechanical apparatus while the patients from the control group were physically managed by a physiotherapist. The intervention period was 12 days. Balance and mobility functions were assessed by means of Berg Balance Scale, Up&go test and 10-m walk test before and after the intervention period. Results. The within-group comparison (1-way repeated measures ANOVA) for the experimental group showed statistically significant improvement (p < 0.05) in Berg Balance Scale, Up&go test and 10-m walk test, while within-group comparison for the control group showed statistically significant improvement only in Berg Balance Scale (p < 0.05). The between-group comparison (2-way ANOVA) showed larger improvement in the experimental group, however, these differences were not statistically significant. Conclusion. Dynamic balance training is useful training modality for patients with HSMN. When exercised in the balance training mechanical apparatus used in this study enables efficient balance and mobility training without requiring physical assistance from a physiotherapist or a caregiver, which opens new possibilities for continuing and more frequent physical exercise and mobility training of patients with HSMN also at their homes.
