The H-reflex has been extensively used to exam the spinal motoneuron excitability. However, no report has demonstrated the test-retest reliability of the H-reflex assessment during voluntary muscle contractions and its relation to joint positions. The purpose of this study was to determine the test-retest reliability of the soleus (SOL) H-reflex during rest and 10, 30, 50% maximal voluntary contractions (MVC) at the ankle joint angles of neutral (0deg), plantarflexion (20deg), and dorsiflexion (-20deg), respectively in a sitting position. Ten healthy participants (age 24.9 ± 5 years, height 168.3±8.8 cm, weight 62.7±12.3 kg) were tested for the SOL H-reflex on two …

The purpose of this study was to determine the test-retest reliability of the soleus (SOL) H-reflex during rest and isometric contractions at 10%, 30%, and 50% of the maximal voluntary force (MVC) at the ankle joint angles of neutral (0°), plantarflexion (20°), and dorsiflexion (-20°) respectively, in a sitting position. Ten healthy participants, with mean age of 24.9 ± 5.0 (SD) years, height 168.3 ± 8.8 cm, weight 62.7 ± 12.3 kg, were tested for the SOL H-reflex (Hmax) on two separate occasions within 7 days. The intra-class correlation coefficient (ICC) for the test–retest of the SOL H-reflex during rest …
