Purpose: The purpose of this study was to describe the movement patterns when lying from an erect stance to a supine position of healthy adults and hemiplegia patients in the age group from 50 to 70. Methods: The subjects used in this study were 230 patients (144 healthy adults and 86 hemiplegia patients). Movement patterns were classified using categorical descriptions of the action of three body regions: the upper extremity, lower extremity, and the head-trunk region. Results: In the most common supine lying position in healthy adults (29.7%), the female fifties age group performed a symmetrical pattern using the upper extremity region, a symmetrical squat pattern using the lower extremity region, and a symmetrical pattern using the head-trunk region (1-1-1). However, in the most supine lying position in hemiplegia patients (32.0%), the female sixties age group usually performed this pattern by using the upper extremity and lower extremity regions in a squat position by raising the leg, and performing rotation of the head-trunk region (3-4-3). Conclusion: Using this clinical therapy, and considering the patients ability to exercise when lying from an erect stance to a supine position, the proper care could be provided. Moreover, this therapy introduces action based on a variety of training methods and on the effects which might result from any changes.

PURPOSE: The aim of the study was to investigate the relationships among the hip joint passive range of motion (ROM) and femur head anterior glide (FHAG) mobility on the gait ability in patients with post-stroke hemiparesis. METHODS: The participants were 37 patients (30 male, 7 female) living in Daejeon. The ROM of the hip joint was measured by using goniometry and the FHAG mobility was measured by using the Prone Figure-4 test. The walking ability was assessed by using the 10m walk test (10MWT), and the 6-min walk test (6MWT). RESULTS: The FHAG was negatively correlated with hip extension (r=-.554, p<.05) and flexion (r=-.337) on the affected side as well as with hip extension (r=-.480), abduction (r=-.361), and adduction (r=-.426) on the non-affected side (p<.05). The gait ability was correlated with the hip joint external rotation on the non-affected side (p<.05), but showed no significant correlation with the hip ROM on the affected side (p>.05). CONCLUSION: This study provides evidence that in patients with post-stroke hemiparesis, the FHAG mobility might be correlated with hip extension. Based on these results, the FHAG mobility may be used to determine the hip extension in patients with post-stroke hemiparesis.

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma, with an incidence of about 0.8% to 5% per million people per year, accounting for 1% of soft tissue sarcomas. In its early stage, DFSP is typically found as a violet or pinkish macule or patch, and it can develop into a palpable mass with ulceration or bleeding. The standard treatment for DFSP is wide local excision of the tumor with a 2- to 3-cm negative margin, and radiation therapy or chemotherapy can be conducted with surgical treatment. A 35-year-old man had a palpable mass on the left side of his occipital scalp without color change, ulceration, or bleeding, which typically are present in malignancy. A magnetic resonance imaging (MRI) scan showed a 3-cm homogenous enhanced mass without adhesion between the scalp and the mass. Unexpectedly, a biopsy revealed the round mass to be DFSP. A wide excision and rotation of the scalp flap were performed. The patient recovered without any complications and received adjuvant radiotherapy at a dose of 60 Gray (Gy) for six weeks. There was no recurrence through six months of follow-up. Here we report this unique case of DFSP with atypical presentation.

Purpose : This study examined the effects of pain, neck dysfunction, psychosocial level, headache impact test (HIT), postural alignment, and trapezius muscle tone of the complex exercise program using dynamic taping in patients with tension headache and chronic neck pain with forward head posture. Methods : The design of this is a randomized controlled trial (RCT). Thirty-four patients with chronic neck pain were screened using a randomized assignment program and assigned to experimental group (n=17) and control group (n=17). Both groups underwent a complex exercise program. In addition, the experimental group dynamic taping was applied to the upper trapezius muscle. All interventions were applied three times per week for four weeks. The visual analogue scale (VAS), the neck disability index (NDI), short form-12 health survey questionnaire (SF-12), Headache impact test-6 (HIT-6), Craniovertebral angle (CVA), Cranial rotation angle (CRA), upper trapezius muscle tone were compared to evaluate the effect on intervention. Results : Both groups showed significant differences before and after the intervention in VAS, NDI, SF-12, HIT-6, and CVA, CRA (p<.05). In addition, significant differences in NDI and upper trapezius muscle tone were observed between the experimental group and control group (p<.05). Conclusion : A complex exercise program using dynamic taping for patients with tension headache and chronic neck pain with forward head posture are effective method with clinical significance in improving the function and reducing upper trapezius muscle tone.

The purpose of the study was to evaluate the effects of sling exercise program on muscle activity and cervical spine curvature of person with forward head posture. The subjects, 25 students, were divided into two groups. This experiment was intended to examine the muscle activity and cervical spine curvature while the subjects had performed the exercises to do for 2 times/week and 4 weeks. The factors of FHP were measured cranial vertical angle, cranial rotation angle, muscular activity and cervical spine curvature. Cervical spine curvature measured craniovertical, craniocervical, cervicohorizontal and upper cervical angle. Collected data were statistically analyzed by SPSS 10.0. After experiment for 4 weeks period, results were as following: Both group was significant difference of the results according to the CVA. Exercise group are more effective to increase muscle activity (p<.05), but cervical spine curvature was no significant difference. This result, we could find out there was a significant correlation between sling exercise and muscle activity, CVA and CRA.

Purpose: This paper presents the long term follow-up results of arthroscopic partial repair for massive irreparable rotator cuff tears using a biceps long head auto graft. Materials and Methods: Forty-one patients with massive irreparable rotator cuff tear, who underwent arthroscopic repair, were reviewed retrospectively. Patients who underwent arthroscopic partial repair using a biceps long head auto graft were assigned to group 1, and patients in group 2 underwent arthroscopic partial repair alone. Patients with a less than 50% partial tear of the long head biceps tendon were included in this study. The clinical scores were measured using a visual analogue pain scale (VAS) for pain, range of motion (ROM), The University of California, Los Angeles shoulder score (UCLA), American Shoulder and Elbow Surgeons Shoulder Score (ASES), and Korean Shoulder Scoring System (KSS) scores preoperatively and at the final follow-up. The acromiohumeral interval (AHI) was measured using plain radiographs taken preoperatively and at the final follow-up, and re-tear was evaluated using postoperative ultrasound or magnetic resonance imaging at the last follow-up. Results: The mean age of the patients was 62.1±12.7 years, and the mean follow-up period was 90.3±16.8 months. No significant differences in the VAS and ROM (forward flexion, external rotation, internal rotation) were found between the two groups (p=0.179, p=0.129, p=0.098, p=0.155, respectively). The UCLA (p=0.041), ASES (p=0.023), and KSS (p=0.019) scores showed functional improvements in group 1 compared to group 2. At the last follow-up, the measured AHI values were 9.46±0.41 mm and 6.86±0.64 mm in group 1 and 2, respectively (p=0.032). Re-tear was observed in six out of 21 cases (28.6%) in group 1 and nine out of 20 cases (45.0%) in group 2; the retear rate was significantly lower in group 1 than in group 2 (p=0.011). Conclusion: Arthroscopic partial repair for a massive irreparable rotator cuff tear using a biceps long head auto graft has significant clinical usefulness in functional recovery and decreases the re-tear rates after surgery than arthroscopic partial repair alone, showing favorable results after a long-term follow-up.

Until several years ago we didn't think seriously about cervical problems as a cause of headaches, but since the publication of articles by Bogduk et al they have gotten more attention. Cervical headaches are associated with movement abnormalities of the structures of the neck such as cervical nerve roots, discs, joints and soft tissues. Considering this, we thought that the atlanto-axial joint could be one of the causes of these headaches. Headaches originating from this joint can be recognized by the fact that the pain worsens with rotation of the head in the horizontal plane. Pain can also be referred to the frontal area or around the orbit. We did atlanto-axial joint blocks using a posterior approach on 10 patients who suffered from this type of headache. The results were promising with 9 out of 10 patients showing more than 50% improvement on the numeric rating scale. There were no serious complications observed. We concluded that the atlanto-axial joint block can be an effective procedure in treating this specific type of headache.

Atlantoaxial facet joint osteoarthritis is rare, often undiagnosed because it may be misdiagnosed as occipital neuralgia, or degenerative cervical spondylosis. Unilateral occipitocervical pain aggravated by head rotation is a specific symptom. Conservative treatment is usually effective. But when the patient complains of intractable neck pain localized to occipitocervical junction and unresponsive to medical therapy, surgical treatment should be considered. Though a few reports of surgically treated atlantoaxial osteoarthritis has been published, surgical outcome is favorable. A case of a surgically treated atlantoaxial osteoarthritis is presented with a review of the literatures.

The servo tracks of disk drives are constructed at the time of manufacture with the equipment of servo track writer. Because of the imperfection of servo track writer, disk vibrations and head fluctuations during servo track writing process, the constructed servo tracks might deviate from perfect circles and take eccentric shapes. The servo track writing error should be corrected because it might cause interference with adjacent tracks and irrecoverable operation error of disk drives. The servo track writing error is repeated every disk rotation and so is periodic time function. In this paper, we propose a new correction algorithm of servo track writing error based on iterative teaming approach. Our correction algorithm can learn iteratively the servo track writing error as accurately as is desired. Furthermore, our algorithm is robust to system model errors, is computationally simple, and has fast convergence rate. In order to demonstrate the generality and practical use of our work, we present the convergence analysis of our correction algorithm and some simulation results.
