Eligible participants will be randomly divided into the following three groups: Experimental Group 1: (Single-task exercise): Perform the exercise protocol without additional cognitive task. Experimental Group 2: (Dual exercise + exercise protocol): Perform the basic low back pain exercise protocol with a simultaneous cognitive task (dual task). Control group: An inactive intervention, Blinding description: This study is a **single-blind randomized controlled clinical trial**. The study follows a **pretest–posttest design** with two intervention groups and one control group. In this study, the outcome assessor will be blinded to group allocation. N/A chronic non-specific low back pain. Intervention 1: Intervention group:(Single-task training): Performing the training protocol without additional cognitive task. Intervention 2: Intervention group: (Dual exercise + training protocol): Performing a basic back pain training protocol along with a simultaneous cognitive task (dual task). Intervention 3: Control group: No exercise intervention.

Control group: No exercise intervention. Back proprioception. Timepoint: Outcome variables are measured at two time points: before and after the fatigue protocol. Method of measurement: Lumbar proprioception is assessed using a hand-held goniometer and the method of Newcomer et al. (2000). The subject, standing with eyes closed, recreates a 30-degree angle of lumbar flexion in three attempts. The mean absolute error of the three repetitions in degrees is recorded as the reconstruction error score, with higher scores indicating poorer proprioception. Lumbar range of motion. Timepoint: Outcome variables are measured at two time points: before and after the protocol. Method of measurement: The range of motion of lumbar flexion and extension is measured using the modified Schober test. After marking reference points on the spine, the subject is asked to bend forward and backward as much as possible. The distance between the two points is measured with a tape measure, and the average of the three repetitions is recorded as the final score. Pain. Timepoint: Outcome variables are measured at two time points: before and after the protocol. Method of measurement: Pain intensity is measured using a visual analog scale (VAS) consisting of a 10-cm horizontal line with two ends, "no pain" (score 0) and "worst possible pain" (score 10). The subject is asked to mark a point on the line and the distance from the zero point is recorded as the pain score. This assessment will be performed at pre-test and post-test. Kinesiophobia. Timepoint: Outcome variables are measured at two time points: before and after the protocol. Method of measurement: kinesiophobia is measured using the Tampa Scale (TSK) consisting of 17 questions on a 4-point Likert scale (1 to 4). The range of scores varies from 17 to 68, with higher scores indicating greater fear of movement. A score of 37 or less is interpreted as low fear and a score above 37 as high fear of movement.
