Bilateral antidromic sensory conduction measurements of the lateral cutaneous branch of the radial nerves of 5 men were performed at intervals before and for 15 minutes following ultrasonic application over a segment of the nerve. The ultrasound was applied over the area of the radial nerve for 5 minutes at a frequency of 1 MHz, continuous wave and using 1.5 watts/sq cm dosage. Nerve bed temperature was continuously recorded during the study via a subcutaneous needle thermistor probe. Eighty measurements were made of temperature latency, amplitude and duration of the nerve action potentials. Amplitude and duration of the nerve action potentials did not change following sonation. Latency and temperature values changed significantly following the application of ultrasound. The latencies decreased, indicating increased speed of conduction, as the subcutaneous temperatures increased. The ultrasound dosage used in this study increased the speed of nerve conduction.
对5名男性桡神经外侧皮支进行双侧逆向感觉传导测量，在超声作用于神经某一段之前及之后15分钟内每隔一段时间进行测量。超声以1兆赫频率、连续波、1.5瓦/平方厘米剂量作用于桡神经区域5分钟。研究期间通过皮下针式热敏电阻探头连续记录神经床温度。对神经动作电位的温度潜伏期、幅度和持续时间进行了80次测量。超声处理后神经动作电位的幅度和持续时间没有变化。超声应用后潜伏期和温度值发生了显著变化。随着皮下温度升高，潜伏期缩短，表明传导速度加快。本研究中使用的超声剂量提高了神经传导速度。
