Effect of Walking Speed on Lower Extremity Internal and External Rotation While Turning 90 Degrees

Yoon, Jang-whon 한국전문물리치료학회 2001 한국전문물리치료학회지 Vol.8 No.4

회전(turning)은 보행 중 방향을 바꾸는 운동 기술(motor skill)이고, 회전 전략(turning strategy)은 회전을 완수하는데 사용되는 일반적 행동 전형(generalized movement pattern)이다. 회전에 대한 보행속도의 영향은 분명하지 않다. 이 연구의 목적은 보행속도의 돌기 전략에 대한 영향을 분석하고 보행속도의 하지 내외 회전(internal and external rotation)에 대한 영향을 분석하는 것이다. 건강한 젊은 성인 15명이 이 연구에 자발적으로 참여하였다. 맥리플렉스 측정 장치(MacReflex measurement system)가 동작 분석(motion analysis)을 위해 사용되었다. 각각의 자원자들은 보행 중 90도 왼쪽으로 회전을 10회씩 완수하였다. 각각의 시도마다 보행속도를 다르게 하기 위해서 세 가지의 다른 요구들(slow, regular, fast)이 임의적으로 주어졌고 각각의 실제 보행속도가 자원자의 무게 중심 변화에 따라 구해졌고 요구별 평균이 구해졌다. 회전 안쪽 발의 스핀(inside foot spin)은 보행속도가 증가함에 따라 증가했지만, 회전 바깔쪽 발의 스핀(outside foot spin)은 보행속도와 상관이 없었다. 하지의 내외 회전은 보행속도와는 상관이 없었지만, 같은 쪽 발의 스핀과는 역관계가 있었다. 회전은 발 스핀이 있는 돌기와 발 스핀이 없는 돌기로 구분되는 것이 합당한 듯 하다. 제한된 시간과 공간 내에서 스핀은 보행속도가 빨라질수록 몸의 전방 운동량(forward momentum)에서 몸의 전방 운동량(forward momentum)으로의 전환이 스핀이 없는 회전 시보다 효율적이다. 고관절의 내외 회전 근육들은 회전 전략에 상관없이 회전되는 동안 몸의 역학(body mechanics)을 조절하는데 중요한 역할을 맡고 있는 것으로 보인다. 앞으로 회전 시 몸의 생체 역학적 그리고 신경 근육적 기전들(biomechanical and neuromuscular mechanisms)을 밝히는 연구들이 필요하다.

Does the Wealthier Elderly Show Better Standing Balance?

Jang-whon Yoon 한국전문물리치료학회 2017 한국전문물리치료학회지 Vol.24 No.1

Background: South Korea is one of fastest aging countries in the world. Poor balance and falls of the elderly are main health issues. Objects: The goal of this study was to understand the association between the socioeconomical factors and the standing balance of elderly living in the rural and urban area. Methods: One hundred sixty-six elderly participants who were older than 65 and were able to walk without an assistive device were recruited in the city of Gwangju and in the rural area of Jeonnam, South Korea. All participants performed the static and dynamic standing balance tests. Static standing balance was measured with chronometer in seconds while standing on one leg. Dynamic balance was tested with the timed up and go test (TUG), measured in seconds while getting up from a chair and walking 3 meters and back to sit. The static and dynamic standing balance was analyzed using analysis of variance and the Fisher’s Least Significant Difference post hoc test. Results: Male participants from both areas had no difference in one leg standing and TUG. The female elderly living in rural area took shorter in TUG than females living in urban area. Age decreased the one leg standing time in both areas while did not affect the TUG significantly. As the monthly income increased, both of one leg standing and TUG increased in urban area, while the medium monthly income showed best performance (it was not statistically significant) in both of one leg standing and TUG in rural area. Conclusion: Socioeconomical factors affects differently the standing balance of the elderly living in rural and urban South Korea. Female living alone in urban area with low monthly income demonstrated worst standing balance in this study.

2-Year Follow up of Balance in Stroke Patients after Myofascial Release using a Tennis Ball - Four Case Reports -

Young-In Hwang,Jang-Whon Yoon,Du-Jin Park 대한고유수용성신경근촉진법학회 2018 PNF and Movement Vol.16 No.1

Purpose: Myofascial release (MFR) is an effective treatment for improving muscle stiffness and balance in neurological patients. This study examined long-term effects of MFR on the balance ability of stroke patients. Methods: MFR using a tennis ball was applied to the lower extremity and sacroiliac joint of the affected side of four stroke patients. The four subjects performed the Berg balance scale (BBS) and Timed up and go (TUG) test at the beginning of an 8-week intervention, directly after the intervention, and 2 years later. Results: The BBS scores indicated a trend toward maintenance of balance (p=0.05), but there was no difference in the TUG time (p=0.47). Conclusion: MFR may be a clinically meaningful intervention to maintain balance in stroke patients over a long period. However, the sample size in this study was too small to draw general conclusions. A larger study with more participants is needed.

소아 가정방문 물리치료의 인식도와 수요도에 관한 설문조사

최선영 ( Sun Young Choi ),윤장원 ( Jang Whon Yoon ) 한국전문물리치료학회 2013 한국전문물리치료학회지 Vol.20 No.3

본 연구는 소아 가정방문 물리치료에 관한 인식도와 수요도, 견해를 알아보기 위해 전국의 인구분포도에 대비하여 소아 물리치료사와 보호자, 의사를 대상으로 설문조사를 실시하였고 다음과 같은 결과를 얻었다. 첫째, 모든 집단이 소아 가정방문 물리치료에 대해인식도는 낮았으나 각 집단 모두 빠른 시일 내에 필요하다는 의견을 보였다. 둘째, 소아 가정방문 물리치료의 참여·이용에 대한 의사여부에서 모든 집단이 높은 참여·이용률을 보였다. 셋째, 운영방안에 대해서는 모든 집단이 의사의 처방이 필요하다고 하였고, 소아 가정방문 물리치료를 시행할 소아 물리치료사로 6∼10년의 임상자격조건을 원하였다. 치료비용에서는 물리치료사는 현재 치료비보다 2배를, 보호자는 현재 치료비와 동일하게를, 의사는 현재 치료비보다 1.5배에 많은 분포를 보였다. 물리치료사, 보호자, 의사 모두 현재와 동일한치료횟수와 1시간의 치료 소요시간을 선호하였다. 이상을 종합해보아 소아 가정방문 물리치료에 대한 인식도는 낮으나 수요도와 참여·이용률이 높음을 알 수있었다. 이렇게 높은 수요도와 참여·이용률을 보이는 소아 가정방문 물리치료를 제도적으로 정립하기 위해서는 실효성을 검증할 수 있는 일정기간의 시범사업을 통해 많은 연구와 조사가 필요하며, 먼저 소아 가정방문 물리치료와 관련된 관계자들의 의견을 충분히 수렴하고 이를 반영하여 소아 가정방문 물리치료 제도 정립을 위해 현재 의료 시스템의 정비가 이루어져야 할 것이다. Pediatric home-based physical therapy (PHBPT) provides professional rehabilitation programs at the patient`s home, where the activities of daily life are actually performed. PHBPT also allows to avoid the difficulties of transporting children with disabilities to the clinic. Despite these advantages, PHBPT is not yet widely practiced in Korea. There is little objective information regarding the opinions of the main stakeholders on PHBPT. To investigate the awareness and demand of PHBPT among the main stakeholders, 41 pediatric physical therapists (PT) (of 60 contacted) were recruited from different regions of Korea on the basis of the regional population distribution. The recruited PTs completed their questionnaires and also participated in collecting questionnaires from 35 medical doctors (MD) with whom they worked and from randomly selected 201 parents of children with disabilities recruited. The overall response rate was 85.5%. The awareness of PHBPT differed between PTs (95.1%) and parents (67.2%) (p<.001). The survey showed that 82.9% of MDs had at least heard about PHBPT. Significantly more parents (83.5%) than MDs (57.1%), and 70.0% of PTs, wanted to start PHBPT service immediately (p<.001). Significantly more parents (90.0%) than PTs (73.2%) were willing to participate in PHBPT (p<.001). Opinions on the details of policies and procedures (i.e., necessity for prescription, treatment cost, and treatment frequency) differed among the respondent groups, but all favored a minimal qualification of 6∼10 years of pediatric experience and a treatment session duration of 1 hour. These findings provide objective information to support health service administrators to understand the current demand and develop feasible policies and procedures of PHBPT in Korea.

Objectives: The purpose of this study is to examine the effects of Juglandis Semen Pharmaco-puncture Therapy on Shoulder Pain. Methods & Results: Clinical studies on shoulder pain were carried out on 34 patients who were treated at Department of Acupuncture & Moxibusition, Samse Oriental Medical Hospital from June to October, 2009. Patients were divided into two groups, i.e. Sample group(Group A) and Control group(Group B). Group B were treated by body acupuncture and cupping therapies while Group A were added juglandis semen pharmacopuncture therapy to therapies of Group A. All patients of both groups were treated three times a week for three weeks. In order to evaluate pain degree, we apply Shoulder Pain and Disability Index(SPADI), Visual Analogue Scale(VAS) and the tool developed by Japan's Industrial Hygienics Society and modified by Korean Doctor. Evaluations were done after first week, second week and third week during period of treatment. Results: Both groups showed significant pain decreasing tendencies. But Group A showed more efficiency comparing to Group B. Conclusions: According to the above-mentioned results, it seems that Juglandis Semen pharmacopuncture therapy could be applied as the effective method for reducing shoulder pain.
