To evaluate the saphenous sensory response by 2 methods and the correlation of obtaining responses bilaterally with body mass index (BMI).
Twenty patients evaluated by 1 electromyographer and 10 patients evaluated by 2 blinded electromyographers.
University electromyography laboratory.
Thirty healthy adult volunteers.
Saphenous sensory response with the recording electrode at the level of the medial malleolus, saphenous sensory response with the recording electrode at the level of the proximal tibia, and sural sensory response with the recording electrode posterior to the lateral malleolus.
Sensory-evoked amplitude and distal latency.
The saphenous sensory response was obtained bilaterally at the knee in 77% of subjects, whereas it was obtained bilaterally at the ankle in only 50% of subjects (P<.05). BMI of greater than 25 kg/m2 resulted in more difficulty in obtaining the saphenous sensory response at the ankle compared with the response at the knee (P<.05).
The saphenous sensory response at the knee is more consistently obtained than the saphenous sensory response at the ankle, and it is not affected by BMI.
通过两种方法评估隐神经感觉反应，并探讨双侧获得反应与体重指数（BMI）之间的相关性。
20例患者由1名肌电图检查者评估，10例患者由2名盲法肌电图检查者评估。
大学肌电图实验室。
30名健康成年志愿者。
在内踝水平用记录电极记录隐神经感觉反应，在胫骨近端水平用记录电极记录隐神经感觉反应，在外踝后方用记录电极记录腓肠神经感觉反应。
感觉诱发电位幅度和远端潜伏期。
77%的受试者在双侧膝关节处获得隐神经感觉反应，而仅50%的受试者在双侧踝关节处获得该反应（P<0.05）。与膝关节处的反应相比，BMI大于25kg/m²的受试者在踝关节处获得隐神经感觉反应更困难（P<0.05）。
膝关节处的隐神经感觉反应比踝关节处的隐神经感觉反应更易获得，且不受BMI影响。
