Neuromuscular Electrical Stimulation in Chronic Low Back Pain

Oswestry Disability Index (ODI), measures the level of disability. It consists of 10 items questioning the severity of pain, self-care, lifting and carrying, walking, sitting, standing, sleep, the degree of pain change, travel and social life. Its Turkish version is validated in 2004. Items are scored between 0 and 5, and the total score is multiplied by two. The maximum score is "100". As the total score increases, the level of disability increases.

It is a scale consisting of a 10-centimeter line that evaluates the intensity of pain. Starting point of scale, 0 = no pain, end point 10 = expressed as the most severe pain encountered in life. Patients are asked to mark the severity of pain on the line. When calculating, the distance between the marked point and the starting point is measured in centimeters. Increasing the score means that the pain intensity increases.

Nottingham health profile is a general quality-of-life questionnaire that measures health problems that a person perceives and how these problems affect normal and daily activities. The questionnaire consists of 38 items and evaluates 6 dimensions related to health: energy, pain, emotional reactions, sleep, social isolation and physical activity. Questions are answered as yes or no. Scoring is done in every section between 0-100. 0 indicates the best health status, 100 worst health status. The total Nottingham Health Profile score is obtained from the sum of the sub-scores. Turkish validity and reliability were shown in 2000.

Participants will be asked to lie in supine position with feet flat, knees flexed 90 degree and hips flexed about 45 degrees. Probe is placed transversely at the intersection point of two lines, one horizontal line passing through umbilicus and second vertical line passing through anterior superior iliac spine to visualize the transversus abdominis, oblique internus and oblique externus. No pressure applied. The image is taken at the end of expiration. Participants will be asked to lie in prone position with a pillow placed under the abdomen to minimize the lumbar lordosis. Probe will be placed longitudinally over L3, L4, L5 spinous processes with reference to the sacrum and moved to both sides to view the multifidus muscles at these levels in a single screen to measure muscle thickness. Then probe will be placed transversely and moved laterally until the facet joints are seen in the screen to visualize the multifidus muscles and to measure its area at each level.
