Background: This study aimed to evaluate the efficacy of pulsed radiofrequency applied using transcutaneous electrodes in carpal tunnel syndrome (CTS). Methods: After randomization, the patients received two cycles of noninvasive pulsed radiofrequency (NiPRF), once weekly, or splinting (the control group) for three months. Clinical evaluations were recorded at baseline and weeks 4 and 8. The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was used to determine the functional status and symptom severity. Results: Sixty-two patients were followed up for three months. There was no difference between the groups in the BCTQ scores before and after treatment. The NiPRF group found a significant difference between the BCTQ measurements at all time intervals (paired sample t-test; P < 0.001). In the splint group, there was a significant difference only between the basal-1st month and basal-3rd month (paired samples t-test; P < 0.001). The main effect of the time variable was statistically significant (ANOVA; P < 0.001), but the group variable was not. There was no correlation between the BCTQ results measured at any time and the electroneuromyelogragphy findings in either group. Conclusions: NiPRF effectively improves symptoms and functionality in patients with CTS for up to 3 months. Thus, NiPRF can be considered an easy, safe, and useful alternative treatment modality for CTS.

Objectives To evaluate the clinical usefulness between muscle energy techniques (MET) and transcutaneous electrical nerve stimulator (TENS), we performed both on elector spinae muscle of acute low back pain patients. Methods After performing MET and TENS, we compared both in terms of electrical activity. We performed MET or TENS on elector spinae muscle of acute low back pain patients in each group (n=15,15). After performing MET or TENS, we analyzed root mean square (RMS), median edge frequency (MEF) and asymmetry index (AI). Results 1. After performing MET on elector spinae muscle of acute low back pain patients, RMS was significantly decreased compared with before (p<0.005). 2. After performing TENS on elector spinae muscle of acute low back pain patients, RMS was significantly decreased compared with before (p<0.005). 3. After performing MET on elector spinae muscle of acute low back pain patients, asymmetric index was significantly decreased compared with before (p<0.05). Conclusions According to above results, performing MET on elector spinae muscle of acute low back pain patients has effect in terms of RMS and asymmetric index. And performing TENS on elector spinae muscle of acute low back pain patients also has similar effect in terms of RMS but has not in terms of asymmetric index.

Objective : This study aimed to evaluate the surgical outcomes of selective median neurotomy (SMN) for spastic wrist and fingers. Methods : We studied 22 patients with wrist and finger spasticity refractory to optimal oral medication and physical therapy. The authors evaluated spasticity of the wrist and finger muscles by comparing preoperative states with postoperative states using the modified Ashworth scale (MAS). We checked patients for changes in pain according to the visual analog scale (VAS) and degree of satisfaction based on the VAS. Results : The preoperative mean MAS score was $3.27{\pm}0.46$ ($mean{\pm}SD$), and mean MAS scores at 3, 6, and 12 months after surgery were $1.82{\pm}0.5$, $1.73{\pm}0.7$, and $1.77{\pm}0.81$ ($mean{\pm}SD$), respectively. On the last follow-up visit, the mean MAS score measured $1.64{\pm}0.9$ ($mean{\pm}SD$). Wrist and finger spasticity was significantly decreased at 3, 6, and 12 months after the operation (p<0.01). The preoperative mean pain VAS score was $5.85{\pm}1.07$ ($mean{\pm}SD$), and the mean pain VAS score on the last follow-up visit after surgery was $2.28{\pm}1.8$ ($mean{\pm}SD$). Compared with the preoperative mean pain VAS score, postoperative mean pain VAS score was decreased significantly (p<0.01). On the basis of a VAS ranging from 0 to 100, the mean degree of patient satisfaction was $64.09{\pm}15.93$ ($mean{\pm}SD$, range 30-90). Conclusion : The authors propose SMN as a possible effective procedure in achieving useful, long-lasting tone and in gaining voluntary movements in spastic wrists and fingers with low morbidity rates.

This study analyzed changes in action potential of supraspinal neuron and motor unit depending on maximum tolerance isometric contraction(MTIC) by electrical stimulation and examined influence of functional electrical stimulation (FES) on spinal neuron adaptation. It selected 40 university students in their twenties and divided into experimental groups of 25% MTIC(I), 50% MTIC I (II), 75% MTIC(III) and 100% MTIC(IV) depending on MTIC by electrical stimulation, and performed isometric contraction of plantar flexor muscle to each experimental group with given contraction for 20 times. It measured V/Mmax and MDF pre and post exercise, compared volume of contraction. 1. V/Mmax ratio showed no significant difference in comparison among experimental groups. 2. There was significant difference in median frequency of gastrocnemius and soleus in action potential motor unit according to comparison among experimental groups(p<.001). When contraction by electrical stimulation was maximum, change was greatest. This results suggest that muscle contraction by electrical stimulation was influence to action potential of spinal motor neuron system which appear optimal level though aspect and difference degree were not in accordance. Consequently, optimal stimulation level of MTIC(50%) by FES would be lead to central nerve adaptation. muscle contraction by electrical stimulation was influence highly to MDF which should be consider to fatigue of motor unit for muscle contraction by electrical stimulation.

Eletrophysiological methods revealed subclinical neuropathy in 26 workers, exposed from 1 to 17 years to lead and whose blood lead (PbB) values had never exceeded $70{\mu}g/100\;ml$, as ascertained by checking the monitor reports of the factory and by careful exposure history. The PbB determinations had been tested repostedly and had been found valid. The main findings were slowing of the maximal motor conduction velocities of the median and ulnar nerves and particularly the conduction velocity of the slower fibers of the ulnar nerve. Eletrophysiological abnormalities comprised fibriliations, diminution of the number of motor units on maximal contraction, and an abnormal. Thus, a dose-response relationship exlets on a group basis. Since the regular monitoring of PbBs in most workers during their entire period of exposure excludes the possibility of a body burden out of proportion to the PbBs silght neuro-logical damage is produced at exposures hitherto regarded as quite sale.

While the success or failure of carpal tunnel release ultimately depends on the interplay of a wide array of factors, a broad understanding of the normal anatomy of the carpal tunnel accompanied by awareness of the possible variations of the individual structures that make up its contents is crucial to optimizing surgical outcomes. While anatomic variants such as extension of the flexor digitorum muscle bellies have been described as a cause of primary carpal tunnel syndrome (CTS), there have been no reports depicting its association with recurrent CTS following initially successful carpal tunnel release, a finding with potentially significant prognostic implications that can aid in operative planning. In such cases where muscle extension is identified preoperatively, careful debulking of the muscle belly may be beneficial in improving long-term surgical outcomes.

From January, 1983, to August, 1993, 23 cases of pericardiectomy for chronic constrictive pericarditis were carried out. The 15 male and 8 female patients ranged in age from 7 to 68 years[mean 39.1 years . All patients underwent pericardiectomy through a median sternotomy. Postoperative complications were low cardiac output[2 patients , wound infection[2 patients , pneumonia[2 patients , and unilateral phrenic nerve palsy[2 patients . One patient died of low cardiac output 1 day after pericardiectomy due to the associated transposition of great artery and hypoplastic right lung. Clinical and pathological findings showed that the cause of constrictive pericarditis was tuberculous in 8 cases[34.8% , idiopathic in 12 cases[52.2% and pyogenic in 3 cases[13.0% . Central venous pressure fell below 10cmH2O by immediate in 6 cases, fell below 10cmH2O by 24hrs in 5 cases and continued above 10cmH2O after 24hrs in 12 cases. Preoperative NYHA functional class of patients showed class I-1, classII-4, class III-14, and class IV-3. Postoperativly NYHA functional class was improved to class I-15, classII-6, class III-1.

Charcot-Marie-Tooth disease (CMT) is the most common hereditary motor and sensory peripheral neuropathy. CMT is usually classified into two categories based on pathology: demyelinating CMT type 1 (CMT1) and axonal CMT type 2 (CMT2) neuropathy. CMT1 can be distinguished by assessing the median motor nerve conduction velocity as greater than 38 m/s. The main clinical features of axonal CMT2 neuropathy are distal muscle weakness and loss of sensory and areflexia. In addition, they showed unusual clinical features, including delayed development, hearing loss, pyramidal signs, vocal cord paralysis, optic atrophy, and abnormal pupillary reactions. Recently, customized treatments for genetic diseases have been developed, and pregnancy diagnosis can enable the birth of a normal child when the causative gene mutation is found in CMT2. Therefore, accurate diagnosis based on genotype/phenotypic correlations is becoming more important. In this review, we describe the latest findings on the phenotypic characteristics of axonal CMT2 neuropathy. We hope that this review will be useful for clinicians in regard to the diagnosis and treatment of CMT.

In this case report, we present a rare case of lipoma of the tendon sheath localized to the wrist which caused median entrapment neuropathy and was successfully treated with surgical excision. Dynamic examination using ultrasonography revealed the exact location of the lipoma. Electrodiagnostic study (EDX) was done before surgery to elucidate combined neuropathy, and surgery for ulnar neuropathy around elbow was also performed simultaneously. Diagnostic ultrasound can be used for dynamic examinations with real-time visualization.
