Intersession reliability for H-reflex measurements arising from the soleus, peroneal, and tibialis anterior musculature.

摘要: The Hoffman reflex (H-reflex) has been widely used throughout neuroscience research, as it allows for the assessment of alpha motoneuron excitability arising from a specific pool. Recently, protocol developed allowing simultaneous examination soleus, peroneal, and tibialis anterior pools elicited single peripheral stimulus. In order this to be useful, reliability measures must established. purpose current study was determine intersession H-reflexes their corresponding M-waves stimulus sciatic nerve. Ten healthy neurologically sound individuals (age: 23 +/- 7 yrs; height: 175 12 cm; mass: 76 22 kg) volunteered participate in investigation. To obtain measurements, nerve stimulated just prior its bifurcation into tibial common peroneal nerves popliteal fossa. A 1-ms square wave pulse delivered 0.2 V increments until maximum M seen each muscle. H-reflex were collected muscle ratios calculated. Intersession over 2 consecutive days estimated using intraclass correlation coefficients (ICC [2.1]). soleus Max H, M, H:M ratio 0.9953, 0.9514, 0.9747, respectively. measurements follows: 0.9979 (Max H), 0.9924 M), 0.9664 (H:M ratio). 0.8591, 0.9968, 0.7810 H. M. ratio, These results indicate that measured musculature with is reliable between sessions. This clinician/researcher reliably investigate multiple about ankle at point time.
