Brief Summary:
Previous studies have shown that stimulation of heel skin mechanoreceptors facilitates the soleus H-reflex, whereas stimulation of metatarsal region mechanoreceptors inhibits the soleus H-reflex. From this perspective, plantar cutaneous receptors may play an important role in the regulation of activities such as walking and running, as well as in the control of spasticity in patients with upper motor neuron lesions. Investigating the effect of heel skin mechanoreceptors on plantar flexor muscle contraction force may provide valuable insight into the potential influence of these mechanoreceptors on locomotor activities and muscle tone, and may offer a foundation for future studies directly addressing these topics.
Detailed Description:
The aim of this study is to investigate the effect of heel skin mechanoreceptors on plantar flexor contraction force. The plantar flexor muscle strength of the participants was evaluated using a force sensor connected to a computer. For the isometric muscle strength measurement, the subjects were asked to perform maximal plantar flexion for 10 seconds. A 5-pulse stimulation package at 15% contraction level was delivered 10 times with a 4-6 second interval. The measurements were repeated 10 times with a 30-second interval. During the plantar flexion muscle strength measurement, the heel skin mechanoreceptors were stimulated at sensory threshold by a square wave electrical current with a pulse duration of 1 microsecond.
