원선재,Sei Un Cho,이우영,이원일 대한재활의학회 2012 Annals of Rehabilitation Medicine Vol.36 No.5
Objective To evaluate the feasibility of ultrasound guided atlanto-occipital joint injection. Method Six atlanto-occipital joints of three cadavers were examined. Cadavers were placed in prone position with their head slightly rotated towards the contra-lateral side. The atlanto-occipital joint was initially identified with a longitudinal ultrasound scan at the midline between occipital protuberance and mastoid process. Contrast media 0.5cc was injected into the atlanto-occipital joint using an in-plane needle approach under ultrasound guide. The location of the needle tip and spreading pattern of the contrast was confirmed by fluoroscopic evaluation.Results After ultrasound guided atlanto-occipital joint injection, spreading of the contrast media into the joint was seen in all the injected joints in the anterior-posterior fluoroscopic view.Conclusion The ultrasound guided atlanto-occipital injection is feasible. The ultrasound guided injection by Doppler examination can provide a safer approach to the atlanto-occipital joint.

Objective: Because bone metabolic changes progress from initial stage of stoke, early prevention and treatment have been important. Isoflavone has been proved to be effective in post-menopausal osteoporosis. Therefore the authors used a stroke rat model and evaluated the effects of isoflavone on bone metabolism from initial stage of stroke. Method: Female Sprague-Dawley rats were randomly divided into 2 separate groups; a stroke without isoflavone supplement group and stroke with isoflavone supplement group. The bone mineral density (BMD) in 4th and 5th lumbar vertebrae were measured at the day before stroke, 11th and 18th days after the stroke. The BMD in excised distal femur and proximal tibia and the maximum load offemur neck and tibia shaft were measured at 18th days after the stroke. Results: On the 18th day after stroke, BMD of stroke with isoflavone group was significantly higher than that of stroke without isoflavone group in 4th and 5th lumbar vertebrae and distal femur. The maximum load of stroke with isoflavone group was significantly higher than that of stroke without isoflavone group in femur neck. Conclusion: The results suggested that isoflavone supplement in stroke rat had beneficial effect on bone metabolism from the initial stage of stroke.

Videofluoroscopic swallowing study (VFSS) used for the diagnosis of dysphagia has limitations in objectively assessing the contractility of the pharyngeal muscle or the degree of the upper esophageal sphincter relaxation. With a manometer, however, it is possible to objectively assess the pressure changes in the pharynx caused by pharyngeal muscle contraction during swallowing or upper esophageal sphincter relaxation, hence remedying the limitations of VFSS. The following case report describes a patient diagnosed with lateral medullar infarction presenting a 52-year-old male who had dysphagia. We suggested that the manometer could be used to assess the specific site of dysfunction in patients with dysphagia complementing the limitations of VFSS. We also found that repetitive transcranial magnetic stimulation was effective in treating patients refractory to traditional dysphagia rehabilitation.

Objective To determine the diagnostic cutoff values of ultrasonographic measurements in ulnar neuropathy at the elbow (UNE).Methods Twenty-five elbows of 23 patients (9 females, 16 males) diagnosed with UNE and 30 elbows of 30 healthy controls (15 females, 15 males) were included in our study. The ulnar nerve cross-sectional area (CSA) was measured at the Guyon canal, midforearm, and maximal swelling point (MS) around the elbow (the cubital tunnel inlet in healthy controls). CSA measurements of the ulnar nerve at each point, the Guyon canal-to-MS ulnar nerve area ratio (MS/G), and the midforearm-to-MS ulnar nerve ratio (MS/F) were calculated.Results Among the variables, only CSA at MS, MS/G, and MS/F displayed significant differences between the control and patient groups. The cutoff value for diagnosing UNE was 8.95 mm2 for the CSA at MS (sensitivity 93.8%, specificity 88.3%), 1.99 for the MS/G (sensitivity 75.0%, specificity 73.3%), and 1.48 for the MS/F (sensitivity 93.8%, specificity 95.0%).Conclusion These findings may be helpful to diagnose UNE.

Objective To determine a diagnostic cut-off value for the cross-sectional area (CSA) of the radial nerve using ultrasonography for radial neuropathy located at the spiral groove (SG).Methods Seventeen patients with electrodiagnostic evidence of radial neuropathy at the SG and 30 healthy controls underwent ultrasonography of the radial nerve at the SG . The CSAs at the SG were compared in the patient and control groups. The CSA at the SG between the symptomatic and asymptomatic sides (ΔSx–Asx and Sx/Asx, respectively) were analyzed to obtain the optimal cut-off value. The relationship between the electrophysiological severity of radial neuropathy and CSA was also evaluated.Results Among the variables examined, there were statistically significant differences in the CSA between the patient and control groups, ΔSx–Asx, and Sx/Asx at the SG. In a receiver operating characteristics analysis, the cut-off CSA was 5.75 mm 2 at the SG (sensitivity 52.9%, specificity 90%), 1.75 mm2 for ΔSx–Asx (sensitivity 58.8%, specificity 100%), and 1.22 mm2 for Sx/Asx (sensitivity 70.6%, specificity 93.3%) in diagnosing radial neuropathy at the SG. There was no significant correlation between CSA and electrophysiological severity score for either patient group.Conclusion The reference value obtained for CSA of the radial nerve at the SG may facilitate investigation of radial nerve pathologies at the SG.

Objective: To suggest a safer and easier technique of suprascapular nerve block by assessing anatomical relationship of the suprascapular notch from a view point of surface anatomy. Method: Fourteen shoulders of seven cadavers were dissected in prone position. The scapular notch was exposed and the articular branch of suprascapular nerve was observed. The length and depth of spine, height and relative position of scapular notch were measured for all of the specimen. Results: The length of the spine was 11.45±0.72 cm. The injection point was measured as relative position of scapular notch on the spine. The ratio between distance from medial border of the spine to injection point and from the injection point to posterior angle of acromion was 1.89±0.2:1. The depth of the spine, which was defined as the shortest vertical distance from the injection point to the scapula was 2.69±0.43 cm, and the vertical distance from this contact point to the base of the scapular notch, e.g. the height of the scapular notch, was 1.18±0.1 cm. Conclusion: We expect we could perform suprascapular nerve block easily and safely with suggested surface landmarks and measured data in this study.

The purpose of this study was to estimate the clinical efficacy of compression garments in cellulite patient. For achieving this purpose, we recuited patient with cellulite in the abdomen or thigh, grade 2 or more. 40 patients were divided into 2 groups - experimental group wearing compression garments and control group wearing non-compression garments of same shape. Each subject has worn experimental garments during 5 weeks, more than 4 hours a day. Evaluation included waist and thigh circumference, sonographic subcutaneous fat thickness measurement at the buttok and hip, body composition analysis and Quality of Life Scale at pre and post of 5 weeks` treatment. There were significant decrease on waist and thigh circumference, subcutaneous fat thickness at the buttock, body weight, BMI, body fat mass in experimental group, but there was no change on any variable in control group between initial and follow-up. These results suggested that wearing compression garments should be recommended as an effective method to reduce factors concerning obesity in cellulite patients.
