Effects of Pulsed Ultrasound Therapy on Sensory Nerve Conduction Parameters and the Pain Threshold Perceptions in Humans.
PM & R : the journal of injury function and rehabilitation, 2016Co-Authors: Othmar Schuhfried, Damir Vukanovic, Christian Kollmann, Karin Pieber, Tatjana Paternostro-slugaAbstract:Abstract Background Therapeutic ultrasound is an often-used clinical modality in the nonsurgical treatment of entrapment neuropathies. To date, the possible mechanism of action of pulsed ultrasound therapy on the peripheral Nerve in the treatment of entrapment neuropathies is unclear. Objective To examine the effects of pulsed ultrasound therapy on peripheral Nerve Conduction parameters. Design A prospective, randomized, single blind, crossover study. Setting Outpatient clinic of a university department of physical medicine and rehabilitation. Participants Twelve healthy volunteers between 22 and 38 years of age (8 male, 4 female). Methods Each patient (blinded) received ultrasound therapy (1W/cm 2 , pulsed: 1:5; over the course of the superficial branch of the radial Nerve of the nondominant arm) and placebo (intensity: zero). The interval between the individual interventions was 1 week. Main Outcome Measurement The Sensory Nerve Conduction velocity, Sensory Nerve action potential, supramaximal stimulation intensity of the Sensory fibers of the radial Nerve, and the pressure pain threshold in the Sensory area of the radial Nerve before and after an ultrasound-therapy and placebo intervention. To compare the results of the intervention with placebo, a paired-samples t test was applied. Results Compared with placebo, a significant increase after pulsed ultrasound therapy was found for the supramaximal stimulation intensity ( P = .02). For the other primary outcome parameters, a significant difference was not found. Conclusions The immediate effect of pulsed ultrasound therapy on a Sensory Nerve is minimal. Therefore, the previously reported benefit of pulsed ultrasound therapy in entrapment neuropathies might be not due to its effect on the Sensory Nerve. Level of Evidence I

Interexaminer repeatability of antidromic ulnar Sensory Nerve Conduction velocity measurements.
Archives of physical medicine and rehabilitation, 2005Co-Authors: Othmar Schuhfried, Martina Angst, Malvina Herceg, Tatjana Paternostro-slugaAbstract:Abstract Schuhfried O, Angst M, Herceg M, Paternostro-Sluga T. Interexaminer repeatability of antidromic ulnar Sensory Nerve Conduction velocity measurements. Objective To determine the interexaminer repeatability of the ulnar antidromic Sensory Nerve Conduction velocity (NCV). Design Test-retest design. Based on a randomization list of various combinations and sequences from 2 of a total of 3 examiners, the measurement was repeated within half an hour by a second examiner blinded to the results of the first examiner. Setting Outpatient department. Participants Twenty-four consecutive healthy subjects (mean age, 38y). Interventions Not applicable. Main Outcome Measures The intraclass correlation coefficient (ICC) and the coefficient of repeatability (CR) were determined for the below elbow to wrist (BE-to-W), above elbow to below elbow (AE-to-BE), and axilla to above elbow (AX-to-AE) segments. Results The ICC was .42 for the BE-to-W, .15 for the AE-to-BE, and −.05 for the AX-to-AE segment. The CR was 12.2m/s for the BE-to-W, 16.2m/s for the AE-to-BE, and 21.4m/s for the AX-to-AE segment. Conclusions During the assessment of the antidromic Sensory NCV of the ulnar Nerve, a moderate amount of interexaminer variability must be taken into account for the BE-to-W segment. More proximally, an extremely large amount of interexaminer variability must be taken into account. This calls into question the usefulness of the antidromic ulnar Sensory NCV for the AX-to-AE and AE-to-BE segments.

Relative slowing of the median antidromic Sensory Nerve Conduction velocity to the ring finger in screening for carpal tunnel syndrome.
The Journal of hand surgery, 2004Co-Authors: Othmar Schuhfried, Gerda Vacariu, Andreas Kopf, Tatjana Paternostro-slugaAbstract:Purpose This study analyzed the accuracy of the relative slowing of the antidromic Sensory Conduction velocity of the median Nerve in comparison with the ulnar Nerve, from the wrist to the ring finger, in the diagnosis of carpal tunnel syndrome (CTS). Methods Eighty-two patients had been referred consecutively to our department to confirm or exclude CTS. The antidromic Sensory Conduction velocities of the median Nerve and the ulnar Nerve from the wrist to the ring finger were determined. The difference between the 2 values was calculated to express the relative slowing of the median Nerve compared with the ulnar Nerve. Carpal tunnel syndrome was diagnosed when the patient had clinical symptoms compatible with CTS confirmed by an established electrophysiologic investigation. The accuracy of a relative slowing of 5 m/s, 10 m/s, and 15 m/s of the median antidromic Sensory Conduction velocity to the ring finger was determined to diagnose CTS. Results At a cut-off value of 5 m/s the sensitivity was 95%, the specificity was 63%, and the efficiency was 79%. At a cut-off value of 10 m/s the sensitivity was 90%, the specificity was 85%, and the efficiency was 88%. At a cut-off value of 15 m/s the sensitivity decreased to 83%, the specificity increased to 93%, and the efficiency was 88%. Conclusions A high accuracy is achieved in the diagnosis of CTS by determining the relative slowing of the median antidromic Sensory Nerve Conduction velocity from the wrist to the ring finger.

Electrophysiological improvement following decompression surgery in tarsal tunnel syndrome
Muscle & nerve, 1991Co-Authors: Thomas W. Arnold, Kyu H. Park, Doo E. KimAbstract:Plantar Nerve Conduction studies 14 months to 3.5 years after decompression surgery in 3 cases of tarsal tunnel syndrome showed an improvement in motor Conduction as well as in Sensory Nerve Conduction. This electrophysiological improvement was associated with clinical improvement. However, minor abnormalities still existed in Sensory Nerve Conduction in all 3 cases.

Effect of hand size on the stimulation intensities required for median and ulnar Sensory Nerve Conduction studies.
Archives of physical medicine and rehabilitation, 2012Co-Authors: Thanitta Thanakiatpinyo, Gulapar SrisawasdiAbstract:Abstract Objectives To examine the effect of hand size on median and ulnar Sensory Nerve Conduction study (NCS) stimulation intensities and pain scores. Design Prospective, single group design to compare main outcomes by using a standard distance of 14cm versus the proximal wrist crease in 3 different hand sizes. Setting Electrodiagnostic laboratory in a department of rehabilitation medicine. Participants Healthy volunteers (N=25) aged 20 to 30 years. Interventions Hand size was determined, based on the distance between the proximal wrist crease and the base of the long finger, resulting in 3 groups (≤11cm, >11–12cm, >12cm) with 12 hands per group. Antidromic median and ulnar Sensory NCSs were performed. The Nerves were randomly stimulated at the proximal wrist crease and 14cm from the recording electrode. Main Outcome Measures Supramaximal stimulation intensities and 10-cm visual analog scale (VAS) pain scores at each stimulating site were recorded and compared. Results Thirty-six hands from 25 young healthy volunteers were studied. There was no correlation between the body mass index (BMI) and stimulation intensity, and BMI and VAS ( r Conclusions When the same distance is used for NCSs regardless of patient size, smaller individuals required greater stimulation and reported greater discomfort. This may reflect greater Nerve depth and suggests that one size fits all may not be the best approach with NCSs.
