Abstract

The conduction of motor nerve and reflex H are two common techniques applied to the lower limbs to assist in determining damage to the nerves and muscles in the lower limbs. The objectives of study were to identify the correlation between age, gender, height, lower limb length, ankle circumference with latent movement time, muscle response amplitude, and conduction velocity in the posterior tibial and deep peroneal nerves, as well as the latent time of the Hoffmann reflex in the posterior tibial nerve. The study was conducted on 34 men and 34 women, evenly divided into two age groups: 40–50 and 51–60. The research results showed a strong positive correlation between age and H-reflex latency (HRL) in women, and an inverse correlation with motor conduction velocity (MCV); men had longer distal motor latency (DML), longer HRL, larger muscle response amplitude (Am), and faster MCV than women. Height, lower limb length, and ankle circumference were positively correlated with HRL in men. No correlation was found with DML, Am, and MCV in all three indices.
