이 연구는 20대와 40대의 급성과 만성 요통환자를 대상으로 척추 주위근육의 단면도를 비교하는 것이다. 20대(남자-9, 여자-10)와 40대(남자-8, 여자9)의 대상자들은 MRI로 요추(4번 하부 종단판) 단면도의 척추주위근육(장요근, 다열근, 척추기립근)들의 크기를 PACS(free-handling technique of the picture archiving and communication system(PACS)을 이용하여 측정하였다. 연구 결과 20대 급성과 만성 요통 환자들의 척추 주위근들의 차이는 통계학적으로 유의성이 없게 나타났으나, 40대 급성과 만성 요통환자들의 척추 주위근들의 차이는 만성 요통환자들이 근 위축이 통계학적으로 유의성 있게 나타났다. 또한 20대와 40대의 만성요통환자 척추 주위근들의 차이도 40대 만성요통 환자들에게 유의성 있게 나타났다. 연구에서 20대 만성환자들의 근 위축은 나타나지 않았으나 40대 만성환자들은 다양한 이유로 근 위축이 나타났다. 따라서 40대의 만성 요통환자들은 조기의 다양한 요부 근력 운동 및 기능적 활동 등으로 허리 주위근육의 위축을 감소시키는 것이 필요하다.

A 36-year-old male patient developed diffuse low back pain. His past medical history was unremarkable and had no family history of neuromuscular disease. He had no bladder and bowel problems. Creatine kinase was 172 U/L (normal < 170). Other fluid and blood chemistry tests were normal. Manual muscle test grades of extremities and sensory examination were normal. Muscle stretch reflexes were normal. Fasciculations and myotonia were not detected. Straight leg raising test was negative. There was no spinal root compression, spinal stenosis, or signal intensity change of spinal cord on magnetic resonance imaging (MRI). Fatty change and atrophy of the cervical, thoracic and lumbar paraspinal muscles were noted on MRI. Nerve conduction studies were normal. Electromyography showed 1+ positive sharp waves in the lumbar paraspinal muscles. Electromyography of upper and lower extremity muscles revealed no abnormal spontaneous activity. We report a rare case of severe paraspinal muscle atrophy with fatty degeneration in a Young Adult.

The trigger point injection technique is widely used in pain clinics for the treatment of acute and chronic pain. Yet it has a variety of complications such asvasovagal syncope, total spinal anesthesia, paralysis, root block, pneumothorax, needle breakage, skin infection, and hematoma formation. Among them, the simultaneous occurrence of psoas and epidural abscesses is extremely rare. We report here on a patient who was diagnosed with epidural and psoas abscesses after paravertebral trigger point injection.

Objectives : This study was designed to evaluate the correlation of the cross-sectional areas(CSA) of paraspinalis(iliocostalis lumborum, multifidus, longissimus thoracis parts lumborum) and psoas muscle and sex, age, change of the VAS(visual analogue scale) and past history of chronic low back pain in patients suffering from HIVD(herniation of intervertebral disc). Methods : Medical records of 140 subjects with HIVD were retrospectively reviewed. The MRI(magnetic resonance imaging) findings on the patients were scanned and analyzed by PiView program to find the paraspinal and psoas muscle CSA and were evaluated by the correlation of sex, age, change of the VAS, and past history of chronic low back pain. Results : There was significant difference between groups in male and female, young-adults age and middle age, middle age and old age, young-adults age and old age. But the correlation of the paraspinal and psoas muscle CSA and past history of chronic low back pain were partially significant. On the other hand, the correlation of the paraspinal and psoas muscle CSA and change of the VAS were not significant. Conclusions : These results suggest that the cross-sectional areas(CSA) of paraspinalis and psoas muscle have relevance to sex and age.

Purpose: This study evaluated the validity of measuring paravertebral muscle function with 3D-NEWTON (Hanmed, Korea) by assessing the correlation between Biodex (Biodex, USA) and surface electromyography (EMG). Methods: Nineteen healthy adults participated. The function of their paravertebral muscle was measured in three ways. Maximum endurance time was measured in seconds when 3D-NEWTON was inclined forward for assessing extensor function, and inclined backward for assessing flexor function. Using surface EMG, maximum muscle activity was obtained from the eractor spinae and rectus abdominis during the 3D-NEWTON measurement. Maximum muscle activity was the mean activity from 10 seconds when the root mean squared firing data was highest. Through Biodex the peak torques of the extensor and flexor were measured during isometric exercises. The Spearman correlation coefficiencts from 3D-NEWTON, surface EMG, and Biodex were calculated. Results: The data from surface EMG and Biodex were statistically correlated when measured for flexor function, but less so for extensor function. In the case of 3D-NEWTON, the correlation coefficient with Biodex was 0.50 (p=0.05), while the coefficient with surface EMG was 0.53 (p=0.02) when measured for extensor function. Similarly, the correlation coefficienct with Biodex was 0.60 (p=0.01), while the surface EMG was 0.51 (p=0.03) for flexor function. Conclusion: 3D-NEWTON was a useful method for measuring paravertebral muscle function and can give helpful information for treating people with diseases associated with the lumbar spine.

본 연구의 목적은 특정 부위의 요부 추간판 탈출과 척추 주위 근 내 지방침윤과의 관계를 알아보기 위함이다. 아울러 환자의 체질량지수(BMI)와 성별에 따른 요부 주위 근의 지방 침윤율의 관계를 알아보고자 하였다. 2010년 5월부터 2012년 5월까지 내원한 환자를 대상으로 연구를 진행했다. 연구 대상자는 30~50세 사이의 중증 추간판 탈출증 환자로 수술적 요법을 시행할 또는 실시한 환자 남녀 40인으로 구성하였고, 측정 및 방법은 환자의 신체계측을 통해 BMI를 산출하였으며, L2-S1까지 디스크 중앙 횡단면에서 요부 주위 근의 단면적과 지방 침윤 면적을 측정하여 근육 내 지방의 침윤율을 계산하였다. 연구 분석은 지방침윤의 남녀 차이를 알아보기 위해 독립표본 T 검증을 시행하였고, 요추 레벨 간 지방침윤의 변화를 알아보기 위해 평균과 표준편차를 산출하여 대응표본 T 검증을 하였다. 또한, BMI와 요부 전체 지방 침윤율과의 상관관계를 알아보기 위해 나이를 제어변수로 한 상관분석을 시행하였다. 이러한 결과로 지방침윤의 남녀 차이는 상위요부(L2-L3)에서 유의한 차이가 있었을 뿐, 나머지 요부(L3-S1)에서는 유의한 차이가 없었으며, 요부 레벨 간 지방침윤율의 변화는 요추3, 4에서 요추4, 5번에서 많이 증가하였다. 또한, 요부(L2-S1)주위 근의 지방 침윤과 체질량지수와는 상관관계가 없음을 확인하였다.
