      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: With consideration of the minimum subjects needed for a reliable statistical analysis, a total of 24 participants who were eligible for random allocation between two groups, were selected. To avoid potential bias in allocation of the participants, their hospital admission IDs were shuffled using MicroSoft Office Excel software package. Then, the first 12 participants appeared in the resultant output column of the software were allocated to the first group (control group) and the second 12 participants appeared in that column were allocated to the second group (intervention group), Blinding description: The patients did not know whether they are receiving the conventional treatment or the interventional treatment. The radiologist who performed muscle thickness measurements also did not the group a patient was coming from. The data analyst knew the group as 1 and 2, so he also did not know which group is conventional and which one is interventional.</study_design>
      <phase>N/A</phase>
      <hc_freetext>Chronic low back pain.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group: hip abductor strengthening exercises 3 times a week and total period of 8 weeks (24 sessions). Each session started with 10 min warm-up period consisted of 5 min stationary biking at a moderate pace and 5 min back stretching exercises. During the back stretching, the low back sustained rotation from supine position, single and double knee to chest from supine position, alternate spinal flexion-extension from 4-point kneeling position, trunk forward stretching while sitting on the heels and with trunk parallel to the floor, side bending in standing position with and without contralateral arm elevation. Then, the patients received the hip abductor strengthening exercises consisting of abduction during four separate positions: supine, side lying, and standing. Intervention 2: Control group: Stabilization exercises 3 times a week and total period of 8 weeks (24 sessions). The stabilization exercises were performed in 6 steps including: 1) segmental control exercises (SCE) with emphasis on training of isolated contraction of the transversus abdominis, multifidus, and pelvic floor muscles, 2) SCE with emphasis on co-contractions of the above-mentioned muscles in the prone, supine, and four-point kneeling positions, 3) SCE as a closed kinematic chain, 4) SCE extension by adding a low weight (0.5-1.5 kg) to create leverage of the limbs, 5) application of SCE in functional situation, and 6) co-contraction of the transversus abdominis and multifidus, muscles during application of an external load, complication of movements, increased load with the lumbar spine in the correct position, and addition of a co-contraction pattern to light aerobic activities such as walking.</i_freetext>
