This study aims to investigate the immediate effects of dual-task neuromuscular warm-up exercises on balance and proprioception in individuals with chronic nonspecific low back pain. Participants will be randomly assigned to either a dual-task neuromuscular warm-up exercise group or a neuromuscular warm-up exercise group. Both groups will also receive the same conventional physiotherapy program. Balance, proprioception, lumbar muscle properties, pressure pain threshold, and flexibility will be assessed before and after the intervention to determine whether adding cognitive tasks to neuromuscular warm-up exercises provides additional immediate benefits.
