Re: Toe training coupled with balance perturbation training
Further to the previous two posts in this thread, but particularly to the first and Dr Karen Mickles work on toe flexor strength ,I thought the following might be of interest .
I recently came across a very interesting BSc thesis by a gentleman called Jonathan W .Wallace . The paper is titled
"Vestibular modulation of the abductor hallucis and abductor digiti minimi muscles in response to changes in head position, visual cues, and cognitive demand " and can be read in full by following the link given below .
Not much I can really add to the quotations from the paper given below other than to say that if the intrinsic foot muscles are significantly atrophied then their contribution to upright standing balance control will likely be reduced .
Strengthening the atrophied intrinsics of older people may therefore improve standing balance control .
from abstract -
"The purpose of this experiment was to determine if
intrinsic foot muscles are modulated by vestibular activity and to elucidate any changes in the association between the vestibular stimulation and electromyography (EMG) responses in response to changes in head position, visual cues, and cognitive demand "
"Muscles which are tonically active, but not involved in
maintaining balance do not exhibit a vestibular myogenic response (Britton et al. 1993;
Forbes et al. 2015). Therefore, it appears that vestibular-evoked muscle responses only occur in those muscles important to maintaining the upright postural task. "
"The findings of this study demonstrate that the vestibular system is able to
modulate activity in the abductor hallucis and abductor digiti minimi during standing. "
" The abductor hallucis and the abductor digiti minimi are likely important
contributors to upright standing balance control and they are capable of dynamic
vestibular responses which can be modulated by other sensory feedback as well as by cortical activity. "
