Normative data of F-wave measures in China
1Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing 100050, China.
Objective:
To establish normal ranges of F-wave measures in China as compared to published data in Brazil and Japan.
Method:
We studied F waves in 127 healthy Chinese subjects, aged 21-78 years old, stimulating the median, ulnar, tibial and peroneal nerves distally and proximaly.
Result:
The F-wave latencies had a linear correlation to the subject height in all nerves tested, showing a steeper (P < 0.05) regression line in Brazil compared to China and Japan for the tibial nerve. The Chinese population also had a higher distally elicited F-wave persistence and faster F wave conduction velocities than previously reported for both ulnar and tibial nerves. These values showed significant difference (P < 0.05) compared to Brazil but not to Japan.
Conclusion:
F-wave latencies show a linear correlation to subject height, although the slope of regression lines varies among countries, reflecting the difference in F-wave persistence and F-wave conduction velocity.
Significance:
Our study provides a rational for the use of a latency-height nomogram in clinical studies and underscores the importance of developing country specific normative data.
