In this paper, we propose a gait pattern recognition method for intelligent prosthesis that enables walking in various environments of femoral amputees. The proposed gait mode changing method is a single sensor based algorithm which can discriminate gait surface and gait phase using only strain gauges sensor, and it is designed to simplify the algorithm based on multiple sensors of existing intelligent prosthesis and to reduce cost of prosthesis system. For the recognition algorithm, we analyzed characteristics of the ground reaction force generated during gait of normal person and defined gait step segmentation and gait detection condition, A gait analyzer was constructed for the gait experiment in the environment similar to the femoral amputee. The validity of the paper was verified through the defined detection conditions and fabricated instruments. The accuracy of the algorithm based on the single sensor was 95%. Based on the proposed single sensor-based algorithm, it is considered that the intelligent prosthesis system can be made inexpensive, and the user can directly grasp the state of the walking surface and shift the walking mode. It is confirmed that it is possible to change the automatic walking mode to switch the walking mode that is suitable for the walking mode.

The aim of this study was to propose our rehabilitation protocol involving Korean medicine for patients with patellar fracture and report its effectiveness. Further, for the same patellar fracture patients, we created different protocols for those who underwent surgical treatment and those who required conservative treatment. Among patients who received inpatient treatment at our hospital for three years from August 2017 to August 2020, we included three patients who underwent surgical treatment for patellar fracture and one patient who required conservative treatment for patellar fracture. The degree of improvement of the patients was evaluated using physical examination findings of the knee joint, numeric rating scale, pain disability index, Lysholm knee score, and walking state. After each treatments, we observed that the range of motion of the knee joint, numeric rating scale, pain disability index, Lysholm knee score, and walking state improved in the patient groups. Even with the same patellar fracture, we observed that different rehabilitation treatments involving Korean medicine should be applied to patients who underwent surgical treatment and those who required conservative treatment. However, further studies are needed to design a rehabilitation protocol involving Korean medicine.

Background: We aimed to compare interlaminar epidural steroid injections (ILESI) and bilateral transforaminal epidural steroid injections (TFESI) on pain intensity, functional status, depression, walking distance, and the neuropathic component in patients with lumbar central spinal stenosis (LCSS). Methods: The patients were divided into either the ILESI or the bilateral TFESI groups. Prime outcome measures include the numerical rating scale (NRS), Oswestry disability index (ODI), Beck depression inventory (BDI), and pain-free walking distance. The douleur neuropathique en 4 questions score was used as a secondary outcome measure. Results: A total of 72 patients were finally included. NRS, ODI, and BDI scores showed a significant decline in both groups in all follow-ups. Third-month NRS scores were significantly lower in the ILESI group (P = 0.047). The percentages of decrease in the ODI and BDI scores between the baseline and the third week and third month were significantly higher in the ILESI group (P = 0.017, P = 0.001 and P = 0.048, P = 0.030, respectively). Pain-free walking distance percentages from the baseline to the third week and third month were significantly higher in the ILESI group (P = 0.036, P < 0.001). The proportion of patients with neuropathic pain in the bilateral TFESI group significantly decreased in the third week compared to the baseline (P = 0.020). Conclusions: Both ILESI and TFESI are reliable treatment options for LCSS. ILESI might be preferred because of easier application and more effectiveness. However, TFESI might be a better option in patients with more prominent neuropathic pain.

The mechanical system of wearable walking assist robot needs to be optimized for adapting with human body structure and the planned control algorithm should have a secure procedure when a incongruity situation which can cause musculoskeletal injury occurs because a wearable robot is attached to a body. The understanding of walking or musculoskeletal motions characteristics must be preceeded and analyzed for developing novel wearable walking assist robot. In this study we tried to find out the capacities of powers and torques of joint actuators to design optimized performances of system and to obtain the analysis data to figure out the characteristics of joint movements during some types of walk. The major types of walk and motion are stair climbing and descending, sit-to-stand motion, and slope walking. In this study all these motions were analyzed experimentally except slope walking.

Purpose: The purpose of this study was to review systematically the effects of home based pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) patients using qualitative synthesis. Methods: Studies designed randomized controlled trials were identified to extract data and to assess the quality of studies in 8 domestic and 3 foreign search engines, and hand search reference reviews. Results: A total of 9 studies met the inclusion criteria. Overall, the methodological quality of the studies ranged from average to poor. Home based pulmonary rehabilitation consisted of exercise, education, and psychosocial interventions. Several exercises such as aerobic, strength, respiratory muscle training, and flexibility were used in home based pulmonary rehabilitation for COPD patients. Upper muscle exercise and walking were the most frequently used exercises. The most common topics for education were 'knowledge of the illness' and 'drug management'. Walking distance test (WDT) and quality of life (QoL) were the most frequently measured as the dependent variables to evaluate rehabilitation outcomes, followed by pulmonary function test (PFT) and dyspnea. WDT was the most effective outcome, followed by dyspnea, QoL and PFT. Conclusion: This study informed about the details of scientific and effective home based rehabilitation programs in COPD patients for future researchers and clinicians. These findings can help expand the recognition and accessibility of home based rehabilitation in COPD patients.
