Office Program Effects on Pain, Posture, Muscle Physiology, Stress, Ergonomics, and Quality of Life in LBP Workers

Summary

This interventional study aims to evaluate the effectiveness of an office worker's program in reducing low back pain and improving physical and psychosocial outcomes among office employees. The primary objective is to determine the effects of the intervention on pain, lumbar posture, muscle physiology (including core stability, flexibility, fatigue, and endurance), ergonomics, stress levels, and quality of life across different intervention groups.

Participants will be assigned to one of three groups:

Group 1: Exercise program, posture education, and standing advice Group 2: Posture education and standing advice Group 3: standing advice only The study will compare outcomes between groups to identify which combination of interventions provides the greatest benefits for office workers with a tendency to experience low back pain.

Conditions

• Low Back Pain

Interventions

BEHAVIORAL

Exercise

Exercise Program: A structured physiotherapist-supervised exercise program designed to improve core stability, lumbar strength, flexibility, and endurance. The program includes progressive abdominal and lumbar muscle strengthening exercises performed three times per week for 12 weeks, with each session lasting approximately 20 minutes. Exercises gradually increase in intensity based on participant tolerance and progression criteria.

BEHAVIORAL

Education

An educational ergonomic intervention delivered using an illustrated posture guidance poster. Participants receive instruction on proper sitting posture, workstation alignment, neutral spine position, and strategies to reduce lumbar strain during daily office activities. Education is delivered at baseline with follow-up reminders throughout the 12-week study period.

BEHAVIORAL

Advice

A behavioral intervention in which participants are advised to take regular standing breaks to reduce prolonged sitting. Participants are instructed to stand for short intervals periodically during working hours, supported by scheduled reminders. No exercise or posture education materials are included in this intervention.
