Sensorial Discrimination in Chronic Low Back Pain

"The progressive core stabilization exercise approach created by Kumar et al. will be used.~* Stage 1; Isolation and facilitation of target muscles~* Stage 2; Trunk stabilization training with increased load under static conditions~* Stage 3; Development of trunk stabilization during slow controlled movement of the lumbar spine.~* Stage 4 and 5; Lumbar stabilization during high speed and dexterous movements. The exercises will last 20-30 minutes in each sessions and twice a week for 10 weeks. The level of stage will be increased when the patients reach the aim of the stage where he/she is at. The duration of the each stage will change depending on the days the patients' need to achieve the aim of the level. For each level, at least four exercise is described."

Training group will be participate in core stabilization exercises (as describe in Control Group). Additionally, Sensorial Discrimination Training (SDT) will be applied on the low back of the patients for 20 minutes before the 20 minutes of core stabilization exercises. SDT is defined as the ability to correctly interpret the characteristics of the stimulus made to a part of the body by the patient. It aims to reverse the cortical reorganization observed in patients with chronic pain. It consists of tactile localization and graphesthesia training, which includes determining the localization and type of stimulus and recognizing the letter/number that drawn in a body part, by the patient. The training consists of five stages progressively, each stage lasting two weeks. As the participants complete the sensory tests at each stage with 90% accuracy, the next stage will be passed. If this accuracy rate is not achieved within two weeks, the stage can be extended for one week.
