Seoyon Yang,Min Ho Chun,Yu Ri Son 대한재활의학회 2014 Annals of Rehabilitation Medicine Vol.38 No.6

Objective To investigate whether virtual reality (VR) training will help the recovery of cognitive function in brain tumor patients.Methods Thirty-eight brain tumor patients (19 men and 19 women) with cognitive impairment recruited for this study were assigned to either VR group (n=19, IREX system) or control group (n=19). Both VR training (30 minutes a day for 3 times a week) and computer-based cognitive rehabilitation program (30 minutes a day for 2 times) for 4 weeks were given to the VR group. The control group was given only the computer-based cognitive rehabilitation program (30 minutes a day for 5 days a week) for 4 weeks. Computerized neuropsychological tests (CNTs), Korean version of Mini-Mental Status Examination (K-MMSE), and Korean version of Modified Barthel Index (K-MBI) were used to evaluate cognitive function and functional status.Results The VR group showed improvements in the K-MMSE, visual and auditory continuous performance tests (CPTs), forward and backward digit span tests (DSTs), forward and backward visual span test (VSTs), visual and verbal learning tests, Trail Making Test type A (TMT-A), and K-MBI. The VR group showed significantly (p<0.05) better improvements than the control group in visual and auditory CPTs, backward DST and VST, and TMT-A after treatment. Conclusion VR training can have beneficial effects on cognitive improvement when it is combined with computer-assisted cognitive rehabilitation. Further randomized controlled studies with large samples according to brain tumor type and location are needed to investigate how VR training improves cognitive impairment.

Conservative Treatment of Thoracic Outlet Syndrome: A Narrative Review

SuYeon Kwon,Seoyon Yang 대한통증연구학회 2022 International Journal of Pain Vol.13 No.2

Thoracic outlet syndrome (TOS) refers to a group of disorders that result in the compression of the brachial plexus and subclavian axillary vessels in the area of the thoracic outlet. Patients with TOS can experience various symptoms, such as neuropathic pain, paresthesia, numbness, and weakness. There is no definite consensus on the appropriate treatment method for TOS, and the treatment usually varies depending on the type of TOS. For patients with venous or arterial TOS, thrombolysis or embolectomy is usually considered first; however, when they do not respond to these treatments, surgical treatments are indicated. Patients with neurogenic TOS are typically treated conservatively. Conservative treatment, including oral medications, injections, rehabilitation therapy, activity modification, and patient education, is used as the initial treatment. This narrative review provides a brief overview of the disease, possible treatments, and exercise protocols to help physicians treat TOS.

Objective To evaluate the gait pattern of patients with gait disturbances without consideration of defilades due to assistive devices. This study focuses on gait analysis using the inertial measurement unit (IMU) system, which can also be used to determine the most appropriate assistive device for patients with gait disturbances. Methods Records of 18 disabled patients who visited the Department of Rehabilitation from May 2018 to June 2018 were selected. Patients’ gait patterns were analyzed using the IMU system with different assistive devices to determine the most appropriate device depending on the patient’s condition. Evaluation was performed using two or more devices, and the appropriate device was selected by comparing the 14 parameters of gait evaluation. The device showing measurements nearer or the nearest to the normative value was selected for rehabilitation. Results The result of the gait evaluation in all 18 patients was analyzed using the IMU system. According to the records, the patients were evaluated using various assistive devices without consideration of defilades. Moreover, this gait analysis was effective in determining the most appropriate device for each patient. Increased gait cycle time and swing phase and decreased stance phase were observed in devices requiring significant assistance. Conclusion The IMU-based gait analysis system is beneficial in evaluating gait in clinical fields. Specifically, it is useful in evaluating patients with gait disturbances who require assistive devices. Furthermore, it allows the establishment of an evidence-based decision for the most appropriate assistive walking devices for patients with gait disturbances.

Objective: To evaluate the swallowing problems after a primary resection in patients with tongue cancer. Methods: Thirty-eight patients with primary tongue cancer, who underwent a glossectomy and had undergone aVideo Fluoroscopic Swallowing Study (VFSS) prior to surgery in a university hospital between January 2010 andMay 2015, were included retrospectively. The clinical and swallowing features, including the VFSS parameters beforeand after surgery, were analyzed. Results: Among the 38 patients, 33 patients were T1 and T2 stage. Thirty-one, six and one patient underwent apartial glossectomy, hemiglossectomy, and total glossectomy, respectively. More than ninety percent of the patientshad a selective neck dissection. All the patients were on a regular diet before surgery and showed no penetrationor aspiration on the VFSS. Immediately after surgery, 33 patients (87%) had to change to non-oral feeding. At discharge,8 patients (21%) maintained non-oral feeding, and 30 patients ate a limited diet. In a telephone survey(mean 19 months after surgery), among the 25 survey participants, 24 patients (96%) reported no problems withtheir regular diet. Conclusion: In tongue cancer patients with low Tumor-Node-Metastasis (TNM), American Joint Committee on Cancer(AJCC) stages, a primary resection of tongue cancer did not cause statistically significant dysphagia after surgery. Although many patients had to change their diet to limited or non-oral feeding immediately after surgery, almost allpatients improved and could eat a regular diet after the long term follow up.

Background/Aims: This study aimed to develop a rehabilitation program for musculoskeletal pain experienced by gastrointestinal endoscopists and to investigate its usefulness. Methods: This was a multicenter cohort study. During the first 2 weeks, a questionnaire regarding daily workload and musculoskeletal symptoms was administered. Then, a rehabilitation program including equipment/posture correction and stretching was conducted during the remaining 6 weeks. Follow-up daily workload and musculoskeletal symptom surveys were distributed during the last 2 weeks. The program satisfaction survey was performed at the 6th and 8th weeks. Results: Among 118 participants (69 men), 94% (n=111) complained of musculoskeletal pain at baseline. Various hospital activities at baseline were associated with multisite musculoskeletal pain, whereas only a few workloads were correlated with musculoskeletal pain after the rehabilitation program. Follow-up musculoskeletal pain was negatively correlated with equipment/posture program performance; arm/elbow pain was negatively correlated with elbow (R=–0.307) and wrist (R=–0.205) posture; leg/foot pain was negatively correlated with monitor position, shoulder, elbow, wrist, leg, and foot posture. Higher performance in the scope position (86.8% in the improvement vs 71.3% in the aggravation group, p=0.054) and table height (94.1% vs 79.1%, p=0.054) were associated with pain improvement. An increased number of colonoscopy procedures (6.27 in the aggravation vs 0.02 in the improvement group, p=0.017) was associated with pain aggravation. Most participants reported being average (32%) or satisfied (67%) with the program at the end of the study. Conclusions: Our rehabilitation program is easily applicable, satisfactory, and helpful for improving the musculoskeletal pain experienced by gastrointestinal endoscopists.

Objective: To evaluate the factors affecting long-term prognosis for dysphagia in tonsil cancer patients, after treatment. Method: This was a retrospective study of subjects who underwent a videofluoroscopic swallowing study (VFSS) following treatment for stage 3 or 4 tonsil cancer. Data including sex, age, cancer characteristics, and methods of cancer treatment were collected. To evaluate the swallowing-related outcome, we collected data including findings regarding the last VFSS, method of feeding, and history of aspiration pneumonia requiring in-patient care. We evaluated the correlation between these data and the characteristics of cancer and treatment methods. Result: Among 32 subjects included in this study, eight had aspiration or penetration confirmed by the last VFSS. There were no significant differences in swallowing-related factors according to the presence of aspiration or penetration in the last VFSS. Patients who underwent curative tonsillectomy retained more residues on the last VFSS than those who did not. Conclusion: Among subjects with tonsil cancer, history of curative tonsillectomy was correlated with more pharyngeal residue. However, other cancer- or treatment-related factors did not affect the outcome of swallowing.
