OBJECTIVE: The purpose of this study was to evaluate the most effective stimulating electrode in TENS for pain relief, and to apply to the treatment of patients with neck and shoulder problems. METHOD: The objects were 30 patients with neck and shoulder problems. In 10 of them, insulated needle electrodes were inserted into a trigger point and electrical stimulation given through the electrodes. In 10 of them, non-insulated needle electrodes were applied as the same method. The others were treated with lidocaine injection into a trigger point and electrical stimulation given through the surface electrode. The effects of pain relief were assessed by visual analogue scale (VAS), pain rating score (PRS), and pain algometer. RESULT: In the group with insulated needle electrode, the average score was reduced 48.33 24.84% in VAS score and 52.00 17.55% in PRS, the pressure of pain algometer was increased 34.97 15.33%. In non-insulated needle electrode group, reduced 43.16 34.62% in VAS score and 43.73 34.85% in PRS, the pressure was increased 22.28 30.62%. The score reduction of surface electrode group was 20.61 15.73% in VAS score and 18.22 16.27% in PRS, the pressure-pain threshold increased as 9.05 12.81%. CONCLUSION: The results suggest that insulated and non-insulated needle electrodes were more effective stimulating electrode in TENS for pain relief than surface electrode.

OBJECTIVE: To know the clinically meaningful findings of ultrasonography in plantar fasciitis. METHOD: Thirty one feet of 24 patients who had clinical diagnosis of plantar fasciitis and 70 feet of 35 healthy volunteers were evaluated with ultrasound. Sagittal sonograms were obtained in the prone position, and the plantar fascia thickness (PFT) was measured at proximal end near its insertion into the calcaneus. Hypoechogenecity, perifascial fluid collection, tendon rupture, calcaneal spur and calcification were also evaluated. RESULTS: The plantar fascia thickness (PFT) of the symptomatic heels (SH) of patients group (4.83+/-0.86 mm) was significantly greater than that of their asymtomatic heels (ASH) (2.95+/-0.57 mm)(p<0.05) and it was also greater than that of control group (2.63+/-0.41 mm)(p<0.05). The range of difference of both PFT was 0.7~3.2 mm in patients group and 0~0.8 mm in control group. Hypoechogenecity was found in 22 SH (71%), perifascial fluid collection in 5 SH (16%) and calcification in 2 SH (6%). Calcaneal bony spur was identified in 7 SH (26%) on simple radiography. CONCLUSION: Increased thickness (>3.8 mm), difference of thickness between SH and ASH (>1.0 mm) and hypoecho genecity of plantar fascia were clinically meaningful ultrasonographic findings of plantar fasciitis, and ultrasonogrphy can be used as the inital imaging modality for the diagnosis.

The characteristics of the surface recorded F responses including minimal latency, mean latency, amplitude, duration, area and shape were investigated in the posterior tibial nerves of rabbits. During a train of 100 stimuli, each F wave was divided by the recurrence of shape into repeaters and nonrepeaters. There was no significant difference between the parameters of repeaters and nonrepeaters such as mean latency, minimal latency, amplitude and area. These findings suggest that the associated discharges of motor neurons generating the repeaters of F wave represented no definite distinctions from that of nonrepeaters in the aspect of the neuron size or the number of neurons contributing to each parameters of F wave. After the sciatic nerve was exposed, it was minimally injured by compression and then F responses were studied. Mean latency and minimal latency were prolonged, and amplitude and area were diminished in post-injured group. The frequency of repeater waves was increased but was not a useful parameter in the assessment of injury model due to a wide range of normal value.

OBJECTIVE: To determine valuable radiologic criteria in diagnosis of pes cavus. METHOD: Thirty eight healthy subjects and twenty seven pes cavus cases were evaluated by radiologic measurements. We evaluated the criteria for longitudinal arch curve by measuring the calcaneal pitch, talocalcaneal angle, talometatarsal angle, metatarsal angle and navicular height I and II. RESULTS: By comparing the pes cavus with the control group, no significant differences in the talocalcaneal angle, metatarsal angle and navicular height I and II were found. Whereas we found a significant difference between the talometatarsal angle and calcaneal pitch. Talometatarsal angle is more sensitive and specific compared to the calcaneal pitch. CONCLUSION: In diagnosis of idiopathic pes cavus, talometa tarsal angle is more reliable in the diagnosis of pes cavus. The ultimate diagnostic value of talometatarsal angle in pes cavus is 6degrees.

OBJECTIVE: This study was conducted to compare the effects of low frequency needle transcutaneous electrical nerve stimulation (TENS) and high frequency needle TENS on experimental pain threshold. METHOD: Twenty two healthy adult subjects were assigned randomly to a low-TENS group or to a high-TENS group. Experimental pain threshold at forearm was determined with pain threshold of electrical simulation using surface electrode and needle electrode. RESULTS: Low-TENS group showed that pain relief was developed after 10 minutes and persisted 3 hours after treatment cessation. Low-TENS group showed a significant increase in experimental pain threshold opposing to high TENS group. CONCLUSION: This results suggest that effect of low frequency needle TENS therapy is better and longer than high frequency needle TENS therapy.

In Korea, Clonorchis sinensis infection is still highly prevalent because case detection in the field is difficult and the detected cases used to be incompletely cured due to treatment failure. The present study tried to control clonorchiasis in an endemic village by repeated treatments with praziquantel every 6 months and to evaluate sonography as a diagnostic measure. By stool examinations, the egg positive rate in the endemic village was 22.7%, but it decreased to 19.6% at 6 months, 15.1% at 12 months. 12.2% at 18 months, 6.3% at 24 months, 11.4% at 30 months, and 6.3% at 42 months after the beginning of repeated praziquantel administration. The sonography showed 61 (49.6%) positive cases of 123 screened residents: among egg-positives the sonography positive rate was 52.2% and among egg-negatives it was still 49%. The rate among cured cases was 64.3% after 6 months, 50.0% after 12 months, 50.0% after 18 months, and 66.7% after 24 months. In a non-endemic village, 64 residents were found egg-negative by fecal examination, but 20 (31.3%) of them were positive by sonography. The present findings indicate that control of clonorchiasis in an endemic village by repeated praziquantel treatment for 42 months is still insufficient and sonography is of little value for diagnosis of clonorchiasis.

OBJECTIVE: The purpose of this study was to investigate the serum and synovial IGF-I levels in 30 patients with knee osteoarthritis (OA) and the relationships among the IGF-I level, pain intensity and severity of knee OA. METHOD: Thirty patients who met criteria of knee OA of American Rheumatology Association participated in this study. Samples of serum and synovial fluid were obtained from all patients. The levels of IGF-I were determined by radioimmunoassay (RIA). The intensity of pain was assessed by Pain Rating Score (PRS) and Visual Analogue Scale (VAS). The severity of knee OA was evaluated by Kellgren's grade of knee OA. RESULTS: The mean serum and synovial IGF-I level was 231.66+/-86.15 ng/ml and 122.42+/-37.79 ng/ml, respectively. There was no correlation between pain intensity and IGF-I levels. Neither was there statistically significant correlation between Kellgren's grade and IGF-I levels. CONCLUSION: The serum and synovial IGF-I levels were not related with pain intensity and severity of knee OA.

OBJECTIVE: To assess the effect of vitamin K2 in addition to risedronate on postmenopausal osteoporosis METHOD: We enrolled 21 postmenopausal osteoporosis women (age: 65.2+/-7.8 years). Ten subjects received risedronate (35 mg, weekly) and vitamin K2 (45 mg, daily) and eleven subjects only received risedronate. They all received calcium citrate 2,130 mg and vitamin D 600 IU daily. The duration of treatment was 7.7+/-1.4 months. Bone mineral density (BMD) of lumbar spine and both femurs, serum osteocalcin and urine deoxypyridinoline were examined at baseline and after treatment. RESULTS: After treatment, BMD, serum osteocalcin and urine deoxypyridinoline were improved in each group but there was no statistical difference between the groups. CONCLUSION: There was no evidence of the benefit of vitamin K2 in addition to risedronate in bone metabolism on postmenopausal osteoporosis.

The purpose of this study was to obtain the normative values for variable parameters of lumbar function with the isoinertial triaxial dynamometer in normal subjects and to compare these values with those of the patients with chronic low back pain. In 82 normal subjects and 27 patients with chronic low back pain, the variable parameters including lumbar range of motion (ROM), maximum isometric torques, and maximum isoinertial velocities were measured with the isoinertial triaxial dynamometer in three axes (rotation, flexion-extension, and lateral flexion). In normal subjects, all parameters except lumbar ROM of all three axes were significantly higher in the male group than the female group. However, other anthropometric variables such as age, height, weight, and body mass index were little correlated with each parameter. Therefore, the normative values were obtained only in consideration of the gender. In patients with chronic low back pain, all parameters except the maximum isometric torques in the female group were significantly lower than those in normal subjects. In addition, the decrease of maximum velocities during the isoinertial exercise was highly correlated to verbal rating scales (VRS) in most axes, especially in the female patient group, but the duration of low back pain was little correlated with the various parameters measured with the isoinertial triaxial dynamometer. In conclusion, all parameters measured with the isoinertial triaxial dynamometer in all three axes were significantly lower in patients with chronic low back pain than those in normal subjects except maximum isometric torques of female group. It was suggested that maximum isoinertial velocities were more reliable and significant than maximum isometric torques for the objective assessment of chronic low back pain.

OBJECTIVE: This study was aimed to demonstrate definite diagnostic radiologic criteria between normal and flatfoot. METHOD: Sixty healthy subjects and fifty two flatfoot cases were evaluated by radiologic measurements. We evaluated criteria for longitudinal arch curve by measuring of calcaneal pitch, talocalcaneal angle, talometatarsal angle, metatarsal angle and navicular height I and II. RESULTS: Over 10 years old, there was significant correlation between normal group and flatfoot in calcaneal pitch, talocacaneal angle, difference angle, metatarsal angle, navicular height I and II. But below 10 years old, there was difference in only talometatarsal angle and metatarsal angle. Therefore talometatarsal angle and metartarsal angle are valuable in diagnosis of flatfoot in all age group. CONCLUSION: In diagnosis of flatfoot, variable radiologic measurement are clinically significant.
