Effects of Active Movement with Skin Mobilization on Range of Motion, Pain, RPE on Patients with Axillary Web Syndrome: A Case Study

최수홍 물리치료재활과학회 2022 Physical therapy rehabilitation science Vol.11 No.4

Objective: This study was conducted to investigate the effect of active movement with skin mobilization on range of motion, pain, and rating of perceived exertion in patients diagnosed with axillary web syndrome after axillary lymph node dissection. Design: A Case reportMethods: It was performed on 7 patients diagnosed with axillary web syndrome after lymph node dissection. The subjects experienced a decrease in the range of joint motion and pain in movement when raising their arms in their daily lives, and complained of discomfort. The active range of motion, numeric rating scale, and modified Borg scale of shoulder joint flexion were measured, and the differences after active movement with skin mobilization were compared. Results: All subjects increased by 24.9 degree on average in active range of motion after active movement with skin mobilization intervention. There was no pain in the maximum range of joint motion measured before intervention, and rating of perceived exertion was significantly reduced. Conclusions: Active movement with skin mobilization can be a very useful way to help improve and treat axillary web syndrome, and it is recommended for improving the function and quality of life of axillary web syndrome patients. and It is also believed that it can be used steadily at home through the education of patients and families.

잉크젯 프린팅된 은(Ag) 박막의 등온 열처리에 따른 미세조직과 전기 비저항 특성 평가

Interest in use of ink-jet printing for pattern-on-demand fabrication of metal interconnects without complicated and wasteful etching process has been on rapid increase. However, ink-jet printing is a wet process and needs an additional thermal treatment such as an annealing process. Since a metal ink is a suspension containing metal nanoparticles and organic capping molecules to prevent aggregation of them, the microstructure of an ink-jet printed metal interconnect 'as dried' can be characterized as a stack of loosely packed nanoparticles. Therefore, during being treated thermally, an inkjet-printed interconnect is likely to evolve a characteristic microstructure, different from that of the conventionally vacuum-deposited metal films. Microstructure characteristics can significantly affect the corresponding electrical and mechanical properties. The characteristics of change in microstructure and electrical resistivity of inkjet-printed silver (Ag) films when annealed isothermally at a temperature between 170 and $240^{\circ}C$ were analyzed. The change in electrical resistivity was described using the first-order exponential decay kinetics. The corresponding activation energy of 0.44 eV was explained in terms of a thermally-activated mechanism, i.e., migration of point defects such as vacancy-oxygen pairs, rather than microstructure evolution such as grain growth or change in porosity.

Purpose: This study verifies the muscle activity around the amputation site during proprioceptive neuromuscular facilitation (PNF) pattern exercise for the upper extremities on the non-amputated part in upper extremity amputees and provides basic data on effective exercise around an amputation site. Methods: Manual resistance was applied to the PNF upper extremity pattern of the non-amputated part to generate muscle activity around the amputation site. The resistance was adjusted to an intensity that could cause maximal isometric contraction. The muscle activity of the amputation site and the non-amputated part was measured using a surface electromyogram for the upper trapezius, middle trapezius, infraspinatus, serratus anterior, and pectoralis major. Results: During the scapular exercise in the painless range, the amputated side showed significantly lower muscle activity and a lower muscle contraction ratio compared with the non-amputated side. During the PNF pattern exercise in the painless range, the amputated side showed lower muscle activity and a lower muscle contraction ratio compared with the non-amputated side. When the direct scapular exercise of the amputated side was compared with the PNF pattern exercise of the non-amputated side, their muscle contraction ratios were similar. Conclusion: This study confirmed the effectiveness of the PNF pattern exercise of the non-amputated part as a way to indirectly train the injured site with no pain for rehabilitation of patients with serious body injuries, such as amputation. It is necessary to develop effective exercise programs for the rehabilitation of the amputation site based on the results of this study.

Purpose: The purpose of this study was to investigate changes in urinary frequency, residual urine volume, and quality of life following pelvic floor exercises using proprioceptive neuromuscular facilitation (PNF) exercise patterns and EMG biofeedback training in patients with stress urinary incontinence. Methods: The subjects were male patients diagnosed with stress urinary incontinence. This study used a single system design (A-B-C.) At baseline, the patients’ symptoms prior to the treatment intervention were recorded (A section). Next, the patients performed the PNF exercise (B section). Thereafter, they performed the PNF exercise, with EMG biofeedback (C section). The subjects performed the exercises in each section for 1 week for a total of 3 weeks. Urinary frequency, residual urine volume, and quality of life of the subjects were measured. Results: The frequency of urination was 9 times in A, 8 times in A ‘and B, and 7 times in C. The amount of residual urine decreased from 23.78ml in A to 21.85ml in A ‘, 14.85ml in B, and 14.63ml in C. The international prostate symptom score was 16 points in A, 14 points in A ‘, 11 points in B, and 7 points at A. The quality of life score was 4 points in A, 4 points in A ‘, 3 points in B, and 2 points in A. Conclusion: Both the PNF exercise and EMG biofeedback decreased urination frequency and residual urine volume and improved the quality of life of patients with stress urinary incontinence. EMG biofeedback training using the PNF technique was the most effective.

근전도바이오피드백을 이용한 거울치료가 상지절단자의 환상통과 근활성도에 미치는 영향 : 사례연구

최수홍,김인균,이상열 한국운동재활학회 2018 한국운동재활학회 학술대회 Vol.2018 No.10

본 사례연구는 거울치료, 근전도바이오피드백 운동 그리고 거울과 근전도바이오피드백을 함께 사용한 운동을 제공하여 환상통의 크기와 절단부 주변의 근육 활성도의 변화를 확인하기 위해 실시되었다. 대상자는 42세 남 성분으로 2018년 5월경 작업 중 기계에 손이 말려 들어가며 발생한 오른쪽 위팔 골절, 자뼈골절, 흉벽 손상 (2nd~11st rib Fx.), 등뼈가시돌기골절 (T7~T10), 등뼈가로돌기골절 (T8~T9) 어깨뼈 골절 등을 주소로 입원 하신 분으로서 순환장애, 절단부 뼈와 피부의 괴사 진행을 막기 위해 정형외과에서 절단 수술을 시행하였다. 3주 동안 매 1주마다 각각 거울치료, 근전도바이오피드백 운동, 근전도바이오피드백을 활용한 거울치료를 진 행하였다 (A-B-C). 표층열치료, 심층열치료, 경피신경자극치료 등 일반적으로 치료실에서 처방되는 열전기치 료기구를 이용한 치료를 동일하게 적용 하였고 그 후 각 주마다 다른 중재를 실시하였다. 환상통은 3주차에 눈에 띄게 감소하였다가 다시 증가하는 추세를 보였고 (3주차에 통증조절 약물 변경을 확인하였다.), 근활성도 는 근전도바이오피드백을 활용한 거울치료, 근전도바이오피드백 운동, 거울치료 순서로 크게 나타났다. 따라서 사지절단 환자의 근육운동을 위해 시각 뿐 아니라 근전도바이오피드백을 활용한 거울치료 등과 같이 여러 감 각을 복합적으로 활용할 것을 제안하는 바이다.

Propranolol 및 MJ 1999 가 저체온심실세동에 미치는 영향

최수홍 대한마취과학회 1974 Korean Journal of Anesthesiology Vol.7 No.1

Profound hypothermia (15°C) was induced in 36 mogrel dogs anesthetized with nitrous oxide-oxygen-d-tubocurarine. Prcpranolol (0.3 mg/kg) or MJ 1999(0.8 mg/kg) was administered intravenously 10 minutes prior to the start of cooling. Significant protection against ventricular fibrillation was provided by MJ 1999, but not by propranolol. With available evidence that hypothermia causes increased catecholamine release and that MJ 1999 is more specific in its beta-adrenergic blocking prcperties than propranolol, the authers findings suggest that ventricular fibrillation during hypothermia is due to beta-adrenergic hyperactivity.

소량 Atropine 이 심박수에 미치는 영향

최수홍 대한마취과학회 1969 Korean Journal of Anesthesiology Vol.2 No.1

In rabbits: (1) Intravenous atropine in the dose of 0.002-0.004 mg/kg caused bradycardia, whereas in that exceeding 0.02 mg/kg tachycardia. Transient but alarming degrees of tachycardia could be observed when 2 mg/kg dose was employed. (2) While Arfonad was being infused, the heart rate changed little regardless of the doses of atropine used. (3) During Arfonad drip, changes in heart rate seemed fairly well correlated with the degree of hypotension, i.e., magnitude of ganglionic blookade. (4) The above findings suggest that, at least in rabbits, small dose atropine-induced cardiac slowing is due to the inhibitory action of atropine on the sympathetic ganglia. This cannot, however, be directly applied to human physiology because of the possible species difference in the regulatory mechanisms of heart rate.
