Effectiveness of a six-month workplace therapeutic micro-exercise program on musculoskeletal pain: Initial anamnestic risk screening via TACOS and outcome evaluation using the Nordic Questionnaire

Abstract

This study evaluated the effectiveness of a six-month therapeutic micro-exercise program in reducing work-related musculoskeletal discomfort among sedentary employees. Prior to the intervention, an anamnestic risk assessment was conducted using TACOS software to determine the prevalence and anatomical distribution of musculoskeletal disorders—including both positive-threshold and minor conditions—across the cervical region, dorsal (thoracic) spine, lumbopelvic area, and upper and lower limbs.

TACOS results showed a higher prevalence of upper limb disorders among female participants, particularly involving the shoulder and wrist. In contrast, male participants exhibited greater spinal complaints, especially in the lumbar and dorsal regions. The occurrence of lower limb discomfort was relatively similar across genders.

Musculoskeletal pain intensity was assessed before and after the intervention using the Nordic Musculoskeletal Questionnaire in combination with a Visual Analogue Scale (VAS) to quantify symptom severity.

The intervention protocol involved brief, targeted neuromuscular activation and joint mobility exercises, performed daily in the workplace setting. These exercises aimed to enhance postural alignment, flexibility, and local muscular endurance.

Post-intervention results revealed statistically significant reductions in region-specific musculoskeletal discomfort (p < 0.05), particularly in the cervical region, lumbopelvic area, and shoulder girdle.

In conclusion, this six-month workplace-integrated micro-exercise program effectively reduced musculoskeletal symptoms in sedentary employees. The TACOS-based baseline screening provided valuable insights into anatomical risk patterns, allowing more precise and individualized exercise targeting. These findings support structured, low-volume, task-integrated physical activity as a feasible and cost-effective strategy for mitigating and managing work-related musculoskeletal disorders.
