Soleus H-Reflex in Different Sitting Postures

Completed

Conditions studied: Compression of Spinal Nerve Root, Spinal Disorder, Low Back Pain

In brief

The purpose of this study was to examine the effect of prolonged sitting duration and three different sitting postures (erect, slumped, and slouched sitting postures) on spinal nerve root function by measuring the soleus (SOL) H-reflex amplitude. In addition, the pressure under the ischial tuberosities during the three sitting postures were assessed and correlated with the SOL H-reflex amplitude.
