Objective
To evaluate the effect of fascia penetration and develop a new technique for lateral femoral cutaneous nerve (LFCN) conduction studies based on the fascia penetration point (PP) identified using ultrasound.
Methods
The fascia PP of the LFCN was localized in 20 healthy subjects, and sensory nerve action potentials (SNAPs) were obtained at four different stimulation points—2 cm proximal to the PP (2PPP), PP, 2 cm distal to the PP (2DPP), and 4 cm distal to the PP (4DPP). We compared the stimulation technique based on the fascia penetration point (STBFP) with the conventional technique.
Results
The SNAP amplitude of the LFCN was significantly higher when stimulation was performed at the PP and 2DPP than at other stimulation points. Using the STBFP, SNAP responses were elicited in 38 of 40 legs, whereas they were elicited in 32 of 40 legs using the conventional technique (p=0.041). STBFP had a comparable SNAP amplitude and slightly delayed negative peak latency compared to the conventional technique. In terms of the time required, the time spent on STBFP showed a more consistent distribution than the time spent on the conventional technique (two-sample Kolmogorov–Smirnov test, p<0.05).
Conclusion
SNAP of the LFCN significantly changed near the fascia PP, and stimulation at PP and at 2DPP provided high amplitudes. STBFP can help increase the response rate and ensure stable and consistent procedure time of the LFCN conduction study.

Abstract

Objective: To investigate the patterns of the temperature effect on motor nerve conduction parameters according to various warming methods and to obtain the most valuable method of warming in clinical setting.

Method: Twenty normal subjects were studied. After limb cooling in cold water, the cooled hands were warmed by hot pack, fan heater, and whirl pool. The median motor responses were recorded at abdnctor pollicis brevis after the stimulation at the wrist during warming at 1 min interval until the temperature increment reached plateau. We measured the temperature changes and conduction parameters were measured at each examination.

Results: The time constants for temperature increment and distal motor latency, duration, area of compound muscle action potentials showed shorter tendency by hot pack and whirl pool than by fan heater (p＜0.05). For the measurement of distal motor latency, time constant of whirl pool (2.49⁑1.21 min) was shorter than that of fan heater (7.12⁑3.12 min) or hot pack (5.96⁑1.98 min) (p＜0.05).

Conclusion: These findings suggest that the use of whirl pool is the most effective method for warming of the cooled limb.
