“…A limitation of this study is that the medial and lateral malleolus vibratory stimulation might also excite ambient cutaneous mechanoreceptors and muscle spindles besides the ankle articular mechanoreceptor. There is indirect evidence that supports our proposition, since it has been shown that activation of subcutaneous mechanoreceptors such as Meissner and Pachinian corpuscles is detected under vibtation (60-250 Hz) 23,36,45) , and non-painful electrical stimulation of the skin of the dorsum pedis over the tarsal joint that the sural nerve innervates can produce EMG responses at latencies exceeding those of the monosynaptic pathway of Sol 46) and SLR in semitendinosus 47) . Furthermore, in a previous study, vibratory stimulation of the sole and crus cutaneous mechanoreceptors induced immediate displacement of the center of pressure during standing 7) .…”

“…We postulate that the inhibition of group I and group II afferents from the ankle joint is possible by applying vibration from the cutaneous to the ankle joint. Noda et al 23) reported that the vibratory perception thresholds of normal subjects under continuous vibration of the malleolus significantly increased. Thus, the question we have to answer is whether reduction of afferent signals from ankle articular mechanoreceptors with vibration contributes to reflexive Sol activity while in an upright stance.…”

Abstract. [Purpose] This study investigated whether afferent signals from ankle articular receptors affect the reflexive activity of the soleus muscle of participants while standing upright.[Methods] The subjects, 14 male healthy adults, stood in an upright position on an electric tilting table. Vibrations (about 90 Hz) were applied to the medial and lateral malleolus of the pivot leg (left leg of all subjects), and for the control condition the vibrators were turned off. The maximum M, H and medium latency reflex amplitudes and latencies were extracted from collected M, H and medium latency reflex (MLR) waves under both conditions. The mean amplitudes and latencies of maximum H and MLR were normalized using each subject's maximum M and height, respectively.[Results] The amplitudes and latencies of maximum H and MLR significantly decreased and were delayed under the malleolus vibration condition compared to the control condition. [Conclusion] We conclude that disynaptic inhibition of group I and II afferent fibers from the ankle joint provoke a decrease in the excitation of the α motoneurons of the soleus. It seems that a supraspinal center hardly regulates the excitability of the α motoneurons of the soleus or group II interneurons when the subject can predict how to maintain standing stability.

“…There is accumulating evidence that Ia and group II afferent fibers from Sol muscle spindles show presynaptic inhibition when a vibration frequency of nearly 100 Hz is applied 13,14,[21][22][23] . This evidence will help us to have a thorough understanding of the delay mechanism of Sol SLR and MLR onsets.…”

“…Each condition was examined randomly. Noda et al 13) reported that 5 minutes of conditioning vibration applied to the malleolus of normal subjects increased the vibratory perception threshold at 10, 60 and 120 seconds, but not at 5 minutes. Therefore, a rest period of 5 minutes was provided between the measurement series during which the subjects adopted a comfortable sitting position.…”

The Role of the Suprasprinal Center during Soleus Stretching Reflexes with Simultaneous Vibration

et al. 2012

Abstract.[Purpose] We examined whether monoaminergic brain stem centers contribute to reflexive soleus (Sol) activity when vibration is applied to ankle joints on a moving platform.[Methods] Ten male subjects (23-35 years) stood with their eyes closed on a movable platform. Vibrators (92 Hz) were applied to the malleolus and Achilles' tendon. Sol electromyographic (EMG) responses of short-(SLR) and medium-latency reflexes (MLR) during platform movement were collected under the control, Sol vibration (SV), and malleolus vibration (MV) conditions. The SLR, MLR areas and their latencies were measured.[Results] The Sol SLR and MLR onsets were significantly delayed under the SV and MV conditions compared to the control condition. The intercept of the regression line under the MV conditions was significantly greater than under the SV condition.[Conclusion] Delays of SLR and MLR onset under the SV and MV conditions might correspond to the length of time required for temporal summation of α-motoneurons due to inhibition of afferent fibers. A rise in the intercept of the regression line under the MV condition means an increase of MLR area. That is, the monoaminergic brain stem centers compensated for stimulation of the group II interneuron via ankle joint afferents acting against the inhibition of the stimulation of Sol α-motoneurons.

Effects of Short and Medium Latency Reflexes of the Plantae Muscle with Ankle Vibration during Sudden Foot Movement

Abstract. [Purpose] This study examined the influence of signals from ankle joint afferent fibers on the reflexive plantae muscle activity during standing subjects.[Subject] Ten male healthy adults participated in this study.[Methods] The subjects stood with their eyes closed on a movable platform that was moved backward. Vibrators (about 90 Hz) were applied to the medial and lateral malleolus of both legs. The vibrators were turned off in the control condition. In the malleolus vibration (MV) condition, vibration stimulus was applied for one minute before the beginning of trials and was continued during the trials (about six minutes). The short (SLR) and medium latency reflex (MLR) of the flexor digitorum brevis muscle (FDB) electromyogram (EMG) responses of the left leg during the platform translations were measured under the control and MV conditions. [Results] The latencies of the FDB SLR and MLR during MV condition were observed to increase significantly in comparison to the control. The integration EMG response values (iEMG) of the SLR and MLR significantly decreased during MV condition.[Conclusion] Excessive afferent signals from the ankle articular mechanoreceptors may participate in the reduction of the reflexive FDB SLR and MLR activities during standing postural perturbation due to changes in the excitability of inhibitory interneurons.
