This study aimed to report the effect of Korean medical treatment including miniscalpel acupuncture on 2 patients who underwen tsurgery for rotator cuff tear. They were treated for almost 4 weeks at the Department of Acupuncture and Moxibustion, Dong-Eui University Korean Medicine Hospital. Visual analog scale (VAS), and range of movement (ROM) were used to evaluate treatment effects. In both patients, shoulder pain and restriction of shoulder joint movement improved after miniscalpel acupuncture treatment. In Case 1, shoulder pain decreased from a VAS score 8 to a VAS score 3, and ROM of the shoulder improved from flexion $100^{\circ}$ to $160^{\circ}$, extension $10^{\circ}$ to $30^{\circ}$, abduction $90^{\circ}$ to 1$30^{\circ}$, adduction $10^{\circ}$ to $40^{\circ}$, internal rotation $10^{\circ}$ to $50^{\circ}$, and external rotation $10^{\circ}$ to $50^{\circ}$. In Case 2, shoulder pain, which was rated a VAS score 8 at first-visit, disappeared, and ROM of the shoulder recovered to normal range. These results suggest miniscalpel acupuncture may contribute to the recovery process after rotator cuff tear surgery.

Purpose : Lymphedema is a common complication in mastectomy patients and is usually characterized by pain, swelling, and limited range of motion (ROM) in the arm. Electromyostimulation (EMS) is widely used for the rehabilitation and recovery of subjects with various neuromusculoskeletal disorders after breast cancer. However, EMS has not yet been used in many Pilates exercises. This study was aimed at comparing the effects of instrument Pilates integrated with EMS on pain, lymphedema, and ROM of the upper extremity (UE) in breast cancer subjects after mastectomy. Methods : Nine female breast cancer subjects who had undergone mastectomy participated in the study. The subjects underwent instrument Pilates with EMS (experimental group) or instrument Pilates only (control group). Pain, lymphedema, and ROM of the UE were measured using the visual analog scale (VAS), the circumference length of the UE, and the ROM of the UE. The Wilcoxon signed-rank test was used to compare the pain, lymphedema, and ROM of the arm before and after the intervention, and the Mann-Whitney U test was used to compare the two groups. The statistical significance level was set to p < .05. Results : In the experimental group, there were significant differences in pain (p<.05) and UE circumference (p<.05) before and after intervention. However, there was no significant difference between the two groups in VAS (p>.05) or circumference length of the UE (p>.05). There was one significant difference between the groups in terms of internal rotation of the ROM of the UE (p<.05). Conclusion : These results show that instrument Pilates exercises combined with EMS may positively affect the internal rotation of the ROM of the UE in breast cancer patients after mastectomy, thus contributing to existing knowledge about instrument Pilates using EMS for the effective management of in breast cancer subjects after mastectomy.

Background: Physical therapy (PT) plays an important role in the recovery of function following anatomic total shoulder arthroplasty (aTSA). While several PT protocols have been published for these patients, there is no standardized protocol for aTSA rehabilitation. This lack of standardization may lead to confusion between patients and physicians, possibly resulting in suboptimal outcomes. This study examines how PT protocols provided by academic orthopedic surgery programs vary regarding therapeutic goals and activities following aTSA. Methods: PT protocols for aTSA available online from the Accreditation Council for Graduate Medical Education accredited orthopedic surgery programs were included for review. Each protocol was analyzed to evaluate it for differences in recommendation of length of immobilization, range of motion (ROM) goals, start time for and progression of therapeutic exercises, and timing for return to functional activity. Results: Of 175 accredited programs, 25 (14.2%) had protocols publicly available, programs (92%) recommended sling immobilization outside of therapy for an average of 4.4±2.0 weeks. Most protocols gave recommendations on starting active forward flexion (24 protocols, range 1-7 weeks), external rotation (22 protocols, range 1-7 weeks), and internal rotation (18 protocols, range 4-7 weeks). Full passive ROM was recommended at 10.8±5.7 weeks, and active ROM was 13.3±3.9 weeks, on average. ROM goals were inconsistent among protocols, with significant variations in recommended ROM and resistance exercise start times. Only 13 protocols (52%) gave recommendations on resuming recreational activities (mean, 17.4±4.4 weeks). Conclusions: Publicly available PT protocols for aTSA rehabilitation are highly variable. Level of evidence: IV.

Background: Repair of superior labral anterior to posterior (SLAP) lesion in patients older than 40 years is controversial. The purpose of this study was to evaluate clinical outcomes of arthroscopic repair of SLAP lesions between younger and older patient groups. Methods: We reviewed 50 patients with isolated type II SLAP lesions who underwent arthroscopic repair. Patients were divided into 2 groups: group 1 included 20 patients aged <40 years, and group 2 included 30 patients aged ${\geq}40years$. Functional outcome at the final follow-up was assessed using a visual analog scale for pain and satisfaction, American Shoulder and Elbow Surgeons form, Constant score, University of California at Los Angeles score, and periodic change in range of motion (ROM). Anatomical outcome was evaluated using computed tomography (CT) arthrography at least 1 year after surgery. Results: No significant differences in functional scores or postoperative ROM were observed between the 2 groups. In group 2, later recovery of ROM (forward flexion, p=0.025; internal rotation, p=0.034) and lower satisfaction score (p=0.06) were observed for atraumatic patients (n=16) compared to patients with traumatic injury (n=14). Fifteen patients in group 1 (15/17, 88%) and 21 patients in group 2 (21/26, 81%) demonstrated a healed labrum on postoperative CT arthrography, and this difference was not significant. Conclusions: The results of this study suggest that arthroscopic repair of type II SLAP lesions can yield good functional and anatomical outcomes regardless of age, if patient selection is adequate. However, the delay in ROM recovery and lower satisfaction, particularly in older patients without traumatic injury, should be considered.

Objectives Through this study, we investigated the effects of Korean medicine treatments on range of motion recovery and pain reduction in patients with Frozen shoulder. Methods In this study, the medical records of 26 patients diagnosed with frozen shoulder were retrospectively observed and analyzed through the IBM SPSS Statistics 25 program. We used range of motion to observe the patient's motion recovery and numeric rating scale to evaluate pain reduction. Results The shoulder range of motion increased statistically significantly from 160.0 (123.5~170.0) to 170.0 (160.0~180.0) (flexion), 115.0 (90.0~135.0) to 167.5 (130.0~178.8) (abduction), 40.8±22.1 to 58.3±16.0 (external rotation) (p<0.001). The average of numeric rating scale reduced statistically significantly from 6.7±2.0 to 3.2±1.4 (p<0.001). Depending on the period, the range of motion increased statistically significantly when visited within 3 months, also the pain score decreased 7.0 (5.4~8.0) to 3.0 (1.8~3.6) statistically significantly when visited within 3 months. In the treatment intervention, the increase in the range of motion and the decrease in pain were statistically significant, especially when the bee venom acupuncture and chuna manaul therapy were used together. Conclusions Korean medicine treatments was effective in improving the range of motion and reducing pain in frozen shoulders. In particular, when treated within 3 months of onset and when bee venom acupuncture and chuna manual therapy were used together, it was effective in recovering the range of motion and reducing pain.

The results of the operative treatment of the Grade III acromioclavicular joint injury is defined by the durability of the reduced joint and free of exertional pain. Several surgical techniques have been applied to reduce and stabilize the joints effectively. Resection of clavicular lateral end and subacromial decompression also could be applied to prevent post-operative arthritic change. Biomechanical studies reveals the role of clavicular elevation and rotation to achieve more than 90 degrees of elevation. It also serves as a attachment site of deltoid and trapezius muscle. The stability and mobility of the both acromioclavicular and coracoclavicular joint are important to get full functional recovery. We modified the methods of coracoacromial ligament transfer described by Weaver-Dunn and by Shoji et a!. to pre­vent pullout of the transferred ligament and to get more improved functional results. Main technical point was harvesting full thickness bone block and fix it through the key-hole to reduce pull out angle.

Rotating disks are used in various machines such as data storage device, gyroscope, circular saw, etc. Transverse vibration of a rotating disk is very important for the performance of these machines. This work proposes a method to suppress transverse vibration of a very flexible rotating disk in non-contacting manner. A system considered in this study is a very flexible rotating disk with a thrust bearing pad which is located underneath the rotating disk. The pressure force generated in the gap between the rotating disk and the thrust pad pushes the rotating disk in the direction of axis of rotation while the centrifugal force and the elastic recovery force push the rotating disk in reverse direction. The balance between these forces suppresses the transverse vibration of the rotating disk. A coupled disk-fluid system is analyzed numerically. The finite element method is used to compute the pressure distribution between the thrust pad and the rotating disk while the finite difference method is used to compute the transverse vibration of a rotating disk. Results show that the transverse vibration of the rotating disk can be suppressed effectively for certain combination of air bearing and operating parameters.
