Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was conducted to determine whether the spinal reflex mechanism underlying the neuromuscular effects of whole body vibration (WBV) is tonic vibration reflex. Local and whole body vibration reflex latencies were measured in young adult healthy volunteers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of eight volunteers were included according to the inclusion and exclusion criteria. The subjects were vibrated while standing upright with the WBV device (PowerPlate® Pro5). The 30, 35 and 40 Hz WBVs were applied for thirty seconds for each frequency with an amplitude of 2 mm. In the same session, 100, 135 and 150 Hz local vibrations were applied to the right Achilles tendon for thirty seconds for each frequency. 100, 135 and 150 Hz local vibrations were then applied to the right heel for thirty seconds for each frequency with an interval of five seconds. Vibration stimuli were recorded accelerometers. Reflex muscle responses were recorded from the right soleus muscle at a sampling rate of 40 KHz. Recording electrodes were placed on the belly of the right soleus muscle and the ground electrode was placed on the right medial malleolus.

The data were recorded with the PowerLab device, the records were processed and analyzed offline from the LabChart program. After the EMG records are filtered and rectified, reflex latencies were measured by cumulative averaging method using the accelerometer records as triggers (Karacan I, Cakar HI, Sebik O, Yilmaz G, Cidem M, Kara S, Türker KS.A new method to determine reflex latency induced by high rate stimulation of the nervous system.Front Hum Neurosci.2014 Jul 18; 8: 536.doi: 10.3389 / fnhum.2014.00536). After determining the Achilles tendon vibration reflex latency and the reflex latency induced by WBV, it was compared with statistical methods.
