  • Purpose: The purpose of this study was to investigate the availability of software for rehabilitation with the Kinect sensor by presenting an efficient algorithm based on machine learning when classifying the motion data of the PNF pattern if the subjects were wearing a patient gown. Methods: The motion data of the PNF pattern for upper extremities were collected by Kinect sensor. The data were obtained from 8 normal university students without the limitation of upper extremities. The subjects, wearing a T-shirt, performed the PNF patterns, D1 and D2 flexion, extensions, 30 times; the same protocol was repeated while wearing a patient gown to compare the classification performance of algorithms. For comparison of performance, we chose four algorithms, Naive Bayes Classifier, C4.5, Multilayer Perceptron, and Hidden Markov Model. The motion data for wearing a T-shirt were used for the training set, and 10 fold cross-validation test was performed. The motion data for wearing a gown were used for the test set. Results: The results showed that all of the algorithms performed well with 10 fold cross-validation test. However, when classifying the data with a hospital gown, Hidden Markov model (HMM) was the best algorithm for classifying the motion of PNF. Conclusion: We showed that HMM is the most efficient algorithm that could handle the sequence data related to time. Thus, we suggested that the algorithm which considered the sequence of motion, such as HMM, would be selected when developing software for rehabilitation which required determining the correctness of the motion.

  • Central cord syndrome (CCS) is the most common incomplete spinal cord injury (SCI) syndrome, occured by cervical hyperextension injury. It is characterized by disproportionately greater motor impairment in the upper extremities compared to the lower extremities, bladder dysfunction, and variable degrees of sensory loss below the level of injury. Recently 36 year-old male was admitted with upper motor neuron weakness, sensory loss in the upper extremities and stiff neck. We report the improvement of his symptoms through both western medical treatment and oriental medical treatment.

  • Perforator free flap (PFF) is currently a major reconstructive option for soft tissue reconstruction in adults. Although PFFs have been used commonly, most reconstructive surgeons still hesitate to perform PFFs in children. The main cause of concern is the perceived high failure rate related to the small diameter of children's perforator vessels. We present 8 consecutive cases of successful transfer of thoracodorsal artery (TDA) & anterolateral thigh (ALT) perforator flap in children. Between 2003 and 2005, 8 children(4 to 13 years old) with soft tissue defects of the extremities were reconstructed with TDA & ALT PFFs. All flaps completely survived. There were no problems relating to vascular spasm or occlusion. Range of motion of reconstructed extremities were fully recovered. Among 8 patients, only 1 patient was performed an additional flap thinning procedure. 8 cases of TDA & ALT perforator flaps were successfully transferred in children. PFF is an excellent option in reconstruction of children as well as in adults because of its thinness, long pedicle length, least donor site morbidity and acceptable donor site scar.

  • A 45-year-old male received cervical continuous epidural block for posterior neck pain radiating to right upper extremity secondary to cervical herniated nucleus pulposus. Three days after epidural catheterization, fever, radicular pain and weakness of both upper extremities were developed. On admission, his temperature was $38.3^{\circ}C$ and showed progressive weakness and numbness in both upper and lower extremities. Cervical epidural abscess was suspected; MRI showed an epidural abscess from C4 to C7 level. Within 24 hours of admission, surgical decompression and drainage was effected. Culture of pus obtained at the lesion yielded Staphylococcus aureus. He was treated with intravenous antibiotics for 7 weeks resulting marked improvement of neurologic signs and symptoms.

  • The purpose of this study was to establish a baseline in order that individuals may exercise safely. Sixty healthy students who were divided into two groups participated in the experiment. One group exercised both arms and legs at 60 rpm and the other at 90 rpm. There was a significant difference between arm and leg exercise in diastolic blood pressure (DBP) and time to target heart rate (tTHR). DBP decreased more in the upper (U//E) than the lower extremity (L/E), but tTHR increased more in the L/E than the U/E (p < 0.05). Systolic blood pressure (SBP) was similar for both arm and leg exercise (p > 0.05). There was also no significant difference between 60 rpm and 90 rpm in SBP, DBP or tTHR in either arm or leg exercise (p > 0.05). In conclusion, the slope of the linear increase in heart rate was steeper for U/E than L/E work. Therefore L/E exercise is safer than U/E exercise.

  • Objective : The purpose of this study was conducted to find correct head and neck patterns, manual contact. verbal commands with proprioceptive neuromuscular facilitation(PNF). Method : This is a literature study with books, seminar note and book for PNF international course. Result : Keep the information of the biomechanics and neural science in head and neck patterns and emphasize that manual contact, verbal commands and visual stimulus. Manual contacting for movement guide and stability of the $C_0/C_1$ verbal command and visual stimulus for correcting of the $C_0/C_1$ movements. Conclusion : In reminder for PNF learning, begin with head and neck and upper trunk patterns. In that time, Knott and Voss(1968) had not enough information about biomechanic movement components and neural science movement components. But Knott and Voss(1968) emphasized that head and neck patterns relate with trunk, upper extremities and lower extremities directly. Alar ligaments are relaxed with the head in neutral and taut in flexion. Axial rotation of the head and neck tightens both alar ligaments. The right upper and left lower portions of the alar ligament limit left lateral flexion of the head and neck. Therefore, head and neck patterns has to be modify. When head moving, eye and vestibular stimulus will be change. During head and neck patterns, must be consider about stimulus of eye system and vestibular system also.

  • Erythermalgia has typical triad of burning pain, redness and localized elevation of body temperature at the involved extremities and according to the etiolgy it can be divided as primary (unknown) and secondary erythermalgia. One case of typical primary erythermalgia involving both lower extremities in 20 year old male patient was reported with dramatic symptomatic improvement for 4 months after bilateral lumbar sympathectomy. And there was another case of primary erythermalgia involving both upper and lower extremities in 12 year old girl, and all the symptoms and signs were disappeared about one week later with combined bilateral thoracic and lumbar sympathectomy. It is considered the first case of primary erythermalgia treated completely with sympathectomy in Korea.

  • The purpose of this study was to examine the effect of ankle-foot orthosis and lumbosacral orthosis on movement patterns used to rise from the supine position to erect stance. Thirty-two healthy adults participated. Subjects were videotaped while rising from a supine position on a floor mat. Each subject performed 10 trials each of three condition;general condition, right ankle-foot orthosis, lumbosacral orthosis. subjects rose most commonly using a symmetrical push pattern of the upper extremities, a symmetrical squat pattern in the lower extremities, a symmetrical in the trunk under each of three conditions. Changes in the incidence of movement patterns occurred in lower extremities of the ankle-foot orthosis and lumbosacral orthosis condition and trunk of the ankle-foot orthosis condition. From a dynamic pattern theory perspective, ankle motion is a control variable for the supine position to erect standing movement.

  • Microvascular free tissue transfer technique is widely accepted for reconstruction of extensive soft tissue defects on the extremities. The system of flap based on the subscapular artery and vein provides the widest ways of composite free flaps. The possible flaps that can be harvested based on this single vascular pedicle include the scapular and parascapular skin flaps, the serratus anterior and latissimus dorsi muscular flaps, the lateral scapular bone flap, the latissimus dorsi-rib flap, and the serratus anterior-rib flap. This combined flap is available to mutiple tissue defects or complex defects because it can incorporated with skin, muscle and bone flaps. A strikig advantage is the independent vascular pedicles of each components, which allow freedom in orientation of each components. So, it can be freely applied to any forms of three demensional defects on the upper and lower extremities. The combination of scapular cutaneous flap and latissimus dorsi musculocutaneous flap can be resurfaced for massive cutaneous defects on the extremities. We report the use of the combined scapular and latissimus dorsi free flap in seven patients to reconstruct massive deefcts on the extremities. There was no flap failure and little complications and disadvantages. The anatomy of this flap is reviewed and the indication and advantages are discussed.

  • Objective: The purpose of this study was to examine the differences in joint position sense (JPS), force sense (FS), and performance level of the upper extremities according to the injury and pain experiences of Korean elite archers. Methods: A total of 15 subjects were briefed about the purpose of this study and agreed to participate voluntarily. JPS was evaluated using the laser-point attached to the wrist while aiming at the target. The difference when relocating while aiming was used as JPS factor. FS was evaluated using load cell through reproduces same muscle strength. Fear-Avoidance Beliefs Questionnaire (FABQ) was used to evaluate psychosocial factors, Kerlan-Jobe Orthopedic Clinic overhead athlete scores (KJOC) and numerical rating scale (NRS) was used to evaluate pain. and performance was evaluated by tournament match score. Results: There is a strong correlation between the current pain and KJOC. Moreover, moderate correlation between KJOC and FABQ also current pain and both upper trapezius and lower trapezius in elite archers. The mean (SD) between groups based on current pain display relatively large margin in force sense than without pain group. The result presents that there is a significant difference in performance and pain. There is a significant difference in the force sense of the upper and lower trapezius and pain. Conclusions: Result present there is a significant difference in functional level in the average comparison between groups according to the presence of absence of current pain. There is a significant difference in the force sense of the upper trapezius as well as lower trapezius and without pain group present a relatively low joint position sense error compared to the groups.
