1. Erdogan, Ferhat. Submandibular mechanical stimulation of upper airway muscles to treat obstructive sleep apnea.

Degree: PhD, Biomedical Engineering, 2018, New Jersey Institute of Technology

The extrinsic tongue muscles are activated in coordination with pharyngeal muscles to keep a patent airway during respiration in wakefulness and sleep. The activity of genioglossus, the primary tongue-protruding muscle playing an important role in this coordination, is known to be modulated by several reflex pathways mediated through the mechanoreceptors of the upper airways. The main objective is to investigate the effectiveness of activating these reflex pathways with mechanical stimulations, for the long-term goal of improving the upper airway patency during disordered breathing in sleep. The genioglossus response is examined during mandibular and sub-mandibular mechanical stimulations in healthy subjects during wakefulness. The genioglossus activity is recorded with custom-made sublingual EMG electrode molded out of silicone. Mechanical vibrations are applied to the lower jaw at 8 and 12 Hz with an amplitude of 5 mm in the first experiment, and to the sub-mandibular area at three different intensities (0.2-0.9 mm, 21-33 Hz) in the second experiment. The effects of sub-mandibular mechanical vibrations are also investigated in severe obstructive sleep apnea patients during a whole night sleep study. The major findings of this study are that the genioglossus reflexively responds to the mechanical vibrations applied to the mandible and the sub-mandibular skin surface in healthy subjects during wakefulness and the sub-mandibular stimulations during sleep terminate the apnea earlier and decrease the level of hypoxia with smaller micro arousals.

2. 柳原, 章. H-反射と緊張性振動反射(TVR)を用いた筋緊張異常及び相反性機能失調の検討 : Reciprocal reflex activity of muscle tone abnormality, studied by electromyography together with tonic vibration reflex (TVR ).

Degree: 1992, Kindai University / 近畿大学

[ABSTRACT] The reciprocal reflex activity in various muscle tone abnor -malities was analyzed using the H-reflex together with tonic vibration reflex ( TVR ). The H- reflex was elicited by short interval ( 5-8 ms ) double volleys while vibratory stimulation (TVR) of 100 Hz was applied to the synergist (gastrocnemius ) or antagonist (peroneus ) muscles . On the other hand, the frequency depression (FD) curve of the H- reflex was plotted at a higherfrequency ( 1- 50 Hz) stimulation. The patients analyzed in this study totaled 48, consisting of 8 normal subjects, 1 with peroneal damage, 22 with spasticity, 5 with rigidity, 9 with cerebellar-brainstem lesion and 3 with cervical cord lesion. In the normal subjects, two successive H- reflexes (H_1 and H_2) were elicited by short interval double volleys, and attenuated by TVR applied to the gastrocnemius as well as TVR applied to the peroneus muscle . The attenuation rates were 68% in gastrocnemius TVR and 80% in peroneus TVR . The FD - curve showed a medium level in lower frequencies and then rose gentlly higher frequencies. In the peroneal nerve damage patient, although the H- reflexes of H_1 and H_2 were attenuated by gastrocnemius TVR they were not attenuated by peroneus TVR because of a loss of the reciprocal innervation. The FD - curve showed a normal characteristic configuration because there were no lesions in the upper center. In spasticity, the H- reflex was not attenuated by gastrocnemius nor by peroneus TVR's at a sufficient rate . The rates were 38% in the former and 46% in the latter. The FD - curve showed a higher level at a lower frequency then showed a steep sloping configuration from medium to higher frequencies. In rigidity, the rates was 26% in gastrocnemius TVR and 51% in peroneus TVR. The FD - curve showed a higher level at a lower frequency, then showed a slighter sloping configuration of higher level from medium to higher frequencies. In cerebellar - brainstem lesion, the rates were 25 % in gastrocne -mius TVR and 49% in peroneus TVR . The FD-curve showed a higher level in all freguencies then showed a gentle sloping configuration at a higher level from medium to higher frequencies. These findings could be considered as a result of the disturbance of the reflex modulation from the upper center . The combined examination of the H- reflex and TVR seems to be a useful diagnostic method and may also help in the deter -minati on of a therapeutic approach that is most appropriate.

3. Σπηλιοπούλου, Στυλιανή. Οι επιπτώσεις διαφόρων τύπων προπόνησης στις μηχανικές ιδιότητες, τα νευρικά και μυοσκελετικά χαρακτηριστικά του ανθρώπου.

In this thesis was examined the training effects of whole body vibration on lower limb strength and balance performance and the electromyographic, static balance and lower limb submaximal strength responses to the application of ankle tendon vibration. 1st examined the effect of Side‐Alternating Vibration (SAV) training on lower limb strength and static balance. 11 women performed static exercises on a vibration plate. Isokinetic and isometric strength of knee ankle, static balance and the EMG was evaluated pre, post and 15 days post‐training. The ankle muscle strength improved, whereas the knee muscle's strength remained unaltered. Postural sway decreased in both the anterior/posterior (25%) and medio/lateral (50%) directions, accompanied by greater EMG activity of peroneus longus during the tandem and one-leg stance. SAV training could enhance ankle muscle strength and reduce postural sway. The greater reduction in medio/lateral sway could be associated with the greater use of ankle evertors as a result of their strength improvement. 2nd examined the effect of Tendon Vibration (TV) on steady isometric submaximal strength and static balance. 29 women performed 3 isometric plantarflexions at 10, 20, 30 and 50% of MVC and 3 postural tasks of increasing difficulty with vibrators applied bilaterally over the Achilles tendon. Both tasks were performed under 4 conditions: (i) eyes open, (ii) eyes closed, (iii) eyes closed and TV, (iv) eyes open and TV. During the isometric tasks, plantarflexion torque and EMG activity were recorded. During posture, the Centre Of Pressure (COP) displacement, EMG, medial gastrocnemius (MGAS) fascicle length and pennation angle were recorded. TV resulted in an increase of plantar flexion torque only at 20 and 30% of MVC, which was accompanied by an increase in EMG activation. During the bipedal stance, the application of the TV resulted in a backward COP displacement, accompanied by an increase in EMG activity. An increase of MGAS pennation angle and decrease of its fascicle length was observed, confirming the MGAS contraction during TV. The vibration-induced increase in EMG activity, probably due to the excitatory Ia afferent input, was confirmed during both strength and postural tasks. However, the vibration effect was attenuated when the amount of central drive to the ankle muscles increased at higher levels of MVC. The present thesis showed that after SAV training, the postural sway reduction, especially in the mediolateral axis, and the greater EMG activity of ankle muscles, could be associated with the greater use of the ankle evertors as a result of their strength improvement. Furthermore, during TV the increase in the EMG activity of the muscles being vibrated is probably due to the excitatory Ia afferent input, which was confirmed during both strength and postural tasks. However, the vibration effect attenuates when the amount of central drive to the ankle muscles became considerable.
