여성 요통환자의 비만 유무가 체중분포와 요부 신전근력 기전에 미치는 영향

초록

This study was aimed to determine the effect for the weight distribution and lumbar extension strength associated with obesity index in female patients of Chronic Low Back Pain. sixty (obesity group(BMI: 25Kg/m²): n=30, non obesity group: n=30) subjects participated. both group were tested on MedX machine for lumbar extension strength. Front heels and back heels were measured twice by using the Tetrax Portable Multiple System. Independent sample t-test was used to analyze the difference between the two group. Results showed that there was no difference between both group even though the weight distribution of back heels was higher than front heels. As for the lumbar extension strength at each angle, the obese back pain group appeared to have a lower muscular strength than the normal group at 0˚, but was stronger at angles 12˚, 24˚, 36˚, 48˚, 60˚, and 72˚. There was a statistically significant difference in muscular strength at lumbar flexion angles 60˚ and 72˚ (p<.05). Overall, the back pain group that was obese according to weight distribution tended to maintain their center of force more backwards by increasing the lordosis degree with abdominal distension. The same results appeared in lumbar extension strength. Especially in the lumbar extension strength test at each angle, a greater strength was shown at 60˚ and 72˚ where the patient bends the upper body over during the test. We were able to realize that the largest extension degree of 0˚ was a factor showing lower muscular strength.
