“…Apparently this casual use of the unstable shoes was not sufficient to cause an adaptation. Our results are thus in line with studies reporting no significant training effect (Ramstrand et al 2010, Turbanski et al 2011). …”

“…Recently, manufacturers have introduced specific shoes featuring unstable sole constructions to induce similar neuromuscular training stimuli. Previous research reported that these shoes improved reactive balance in children with development disabilities [6], improved static and dynamic balance in adults with osteoarthritis [7] and in middle-aged adults [8,9], and also in young subjects in dynamic conditions like standing on a moveable platform [10]. Electromyography studies revealed changes in the ankle joint during quiet standing [8,11], gait and running [12,13].…”

Purpose: This study investigated the influence of long-term wearing of unstable shoes (WUS) on compensatory postural adjustments (CPA) to an external perturbation.Methods: Participants were divided into two groups: one wore unstable shoes while the other wore conventional shoes for 8 weeks. The ground reaction force signal was used to calculate the anterior-posterior (AP) displacement of the centre of pressure (CoP) and the electromyographic signal of gastrocnemius medialis (GM), tibialis anterior (TA), rectus femoris (RF) and biceps femoris (BF) muscles was used to assess individual muscle activity, antagonist co-activation and reciprocal activation at the joint (TA/GM and RF/(BF+GM) pairs) and muscle group levels (ventral (TA+RF)/dorsal (GM+BF) pair) within time intervals typical for CPA. The electromyographic signal was also used to assess muscle latency. The variables described were evaluated before and after the 8-week period while wearing the unstable shoes and barefoot. Results: Long-term WUS led to: an increase of BF activity in both conditions (barefoot and wearing the unstable shoes); a decrease of GM activity; an increase of antagonist co-activation and a decrease of reciprocal activation level at the TA/GM and ventral/dorsal pairs in the unstable shoe condition. Additionally, WUS led to a decrease in CoP displacement. However, no differences were observed in muscle onset and offset. Conclusion: Results suggest that the prolonged use of unstable shoes leads to increased ankle and muscle groups' antagonist co-activation levels and higher performance by the postural control system.

“…It has been demonstrated that wearing this kind of unstable shoe leads to changes in the ankle control pattern during quiet standing (Landry et al, 2010;Sousa et al, 2012) and gait (Romkes et al, 2006). However, most studies related to postural control have been focused only in centre of pressure (CoP) excursions (Landry, et al, 2010;Ramstrand et al, 2010;Turbanski et al, 2011). To the best of our knowledge, no previous study has analysed the influence of unstable shoe wearing on muscle compensatory responses.…”

This study investigated the influence of wearing unstable shoe construction (WUS) on compensatory postural adjustments (CPA) associated with external perturbations. Thirty two subjects stood on a force platform resisting an anteriorposterior horizontal force applied to a pelvic belt via a cable, which was suddenly released, under two conditions: barefoot and WUS. The electromyographic (EMG) activity of gastrocnemius medialis, tibialis anterior, rectus femoris, biceps femoris, rectus abdominis, and erector spinae muscles and the centre of pressure (CoP) displacement were acquired to study CPA.The EMG signal was used to assess individual muscle activity and latency, antagonist co-activation and reciprocal activation at joint and muscle group levels. Compared to barefoot, WUS led to: (1) increased gastrocnemius medialis activity, (2) increased total agonist activity, (3) decreased antagonist co-activation at the ankle joint and muscle group levels, (4) increased reciprocal activation at the ankle joint and muscle group levels, and (5) decrease in all muscle latencies. No differences were observed in CoP displacement between conditions. These findings demonstrate that WUS led to a reorganization of the postural control system associated to improved performance of some components of postural control responses.
