This study will investigate whether adding cognitive tasks to core stabilization exercises improves the ability to perform physical and mental tasks simultaneously in adults with chronic nonspecific low back pain. A total of 90 participants aged 18-55 years will be randomly assigned to one of two groups. Both groups will complete the same supervised core stabilization exercise program, consisting of 18 sessions over six weeks. In the dual-task group, participants will perform cognitive activities, such as mental arithmetic and memory tasks, while exercising. In the single-task group, participants will perform the same exercises without additional cognitive tasks. The primary outcome will be motor dual-task cost during the Timed Up and Go test, which measures the change in functional mobility performance when a cognitive task is performed simultaneously. Secondary outcomes will include cognitive dual-task performance, walking speed, balance, pain intensity, disability, and fear of movement. Assessments will be conducted before treatment, immediately after the intervention, and at the 12-week follow-up. The study aims to determine whether combining cognitive and physical tasks during core stabilization training provides additional benefits compared with conventional core stabilization exercises alone.

Motor Dual-Task Cost During the Timed Up and Go Test
Motor dual-task cost will be calculated as \[(dual-task TUG time - single-task TUG time) / single-task TUG time\] × 100. TUG time will be measured in seconds. During the dual-task condition, participants will count backward by threes while performing the TUG test. Two trials per condition will be averaged. Higher percentages indicate greater deterioration in motor performance under dual-task conditions. The primary comparison will be the post-intervention value adjusted for baseline performance and age stratum.
Baseline and post-intervention (approximately 6 weeks)
Cognitive Dual-Task Cost During the Timed Up and Go Test
Baseline, post-intervention (approximately 6 weeks), and 12-week follow-up.
Walking Speed During the 10-Meter Walk Test
Baseline, post-intervention (approximately 6 weeks), and 12-week follow-up.
Single-Leg Stance Test Performance
Baseline, post-intervention (approximately 6 weeks), and 12-week follow-up.
Pain Intensity Measured by the Numerical Rating Scale
Baseline, post-intervention (approximately 6 weeks), and 12-week follow-up.
Disability Measured by the Oswestry Disability Index
Baseline, post-intervention (approximately 6 weeks), and 12-week follow-up.
Participants in this group will perform a six-week supervised core stabilization exercise program combined with concurrent cognitive tasks. The intervention will consist of 18 sessions, three sessions per week, with each session lasting 40 minutes. The exercise program will progress through muscle activation, static stabilization, and dynamic functional stabilization stages. Cognitive tasks will include backward counting, verbal fluency, reverse spelling, and working-memory activities, with progressively increasing difficulty. Participants will be instructed to give equal attention to the motor and cognitive tasks.
Participants in this group will receive the same six-week supervised core stabilization exercise program without concurrent cognitive tasks. The program will consist of 18 sessions, three sessions per week, lasting 40 minutes each. Exercise content, intensity, progression, session duration, and therapist supervision will be identical to the experimental group. The physiotherapist will provide only standard instructions regarding exercise performance, without additional cognitive or attention-demanding tasks.
Participants will receive 18 supervised individual sessions over six weeks (three sessions per week, 40 minutes per session). Each session includes a 5-minute warm-up, 30 minutes of core stabilization exercises, and a 5-minute cool-down. Exercises progress from deep trunk muscle activation (weeks 1-2) to static stabilization (weeks 3-4) and dynamic functional stabilization (weeks 5-6). Concurrent verbal cognitive tasks increase in difficulty and include backward counting, category naming, verbal fluency, reverse spelling, auditory working-memory tasks, and category switching. Participants are instructed to give equal attention to motor and cognitive tasks. The first session is dedicated to exercise instruction.

Participants will receive 18 supervised individual sessions of core stabilization exercises over six weeks (three sessions per week, 40 minutes per session). The exercise program will be identical to that of the dual-task group, progressing through muscle activation, static stabilization, and dynamic functional stabilization stages. No concurrent cognitive tasks will be performed.
