The H-reflex is one of the most popular topics in reflexology and one of the late responses involved in routine nerve conduction studies in the electromyography (EMG) laboratory. The H-reflex is generally recorded from the gastrocnemius-soleus muscles (tibial H-reflex) by stimulating the tibial nerve in the lower extremity. Tibial H-reflex is a sensitive measurement for examining S1 radiculopathy. Although there are plenty of studies related to the Soleus muscle registered H-reflex in S1 radiculopathy in the literature, there is no study in which the H-reflex is used in L5 muscles in diagnosing L5 radiculopathies. The aim of this study is to investigate the effectiveness of the H-reflex by using a different method in the distinction between L5 and S1 radiculopathies.

The H-reflex is generally recorded from the gastrocnemius-soleus muscles (tibial H-reflex) by stimulating the tibial nerve in the lower extremity. Tibial H-reflex is a sensitive measurement for examining S1 radiculopathy.
Hoffman et al. developed a method for simultaneously evaluating the H-reflex obtained from different muscles with single peripheral nerve stimulation. With this method, H-reflex measurement can be done in three leg muscles, including the tibialis anterior, peroneus longus, and soleus with sciatic nerve stimulation. Thus, the L5 and S1 roots can be evaluated separately with a single stimulation.

The H-reflex was evaluated simultaneously using the method developed by Hoffman et al. using superficial recording electrodes in a 3-channel way from the Tibialis anterior, Peroneus Longus, and Soleus muscles.
Latency was recorded when the maximum H-reflex amplitude was obtained. The onset H-reflex latency was marked and measured for each muscle. The patients were evaluated according to EMG and magnetic resonance imaging findings. The latency of the H-reflex was compared with the contralateral extremity in each group.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
