Objectives: This study was planned to investigate the relationship between Hoffmann reflex (H-reflex) and nonverbal intelligence in volenteer university students ranging in age from 18 to 21 years.
Material and methods: All were healty, devoid of neurological or psychiatric signs and symptoms. Nonverbal intelligence (IQ) was determined by the Cattell’s Culture Fair Intelligence Test. The recordings were made from the gastrocnemius-soleus muscles of both legs.
Results: The mean values were found to be 2.82 ± 3.21 mV, 27.83 ± 2.34 ms, 82.14 ± 34.67 mVs and 3.21 ± 3.76 mV, 28.24 ± 2.15 ms, 80.96 ± 27.99 mVs and 99.50 ± 8.04 for right H-reflex amplitude, latency, area and left H-reflex amplitude, latency, area and IQ, respectively.
Conclusion: These results showed that there was no significant relationship between H-reflex and nonverbal intelligence.
Key words: Hoffmann reflex (H-reflex), nonverbal intelligence (IQ), laterality
