Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Research question: Is there any effect of office worker's program on pain intensity, lumbar posture, muscle physiology, ergonomics, stress and quality of life among office workers with low back pain? Research objective: To determine the effect of office worker's program on pain intensity, lumbar posture, muscle physiology, ergonomics, stress and quality of life Research hypothesis: There is significance different on pain intensity, lumbar posture, muscle physiology, ergonomics, stress and quality of life

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomly assigned into three parallel intervention groups that differ in the components of the office worker's program they receive. The three groups will run concurrently throughout the study period. Exercise group will receive a combined intervention consisting of an exercise program, posture education, and standing advice. Education group will receive posture education and a standing advice. Control Group will receive only the standing advice as a minimal intervention control. Each participant remains in their assigned group for the duration of the study, and outcomes will be compared across groups to evaluate the relative effectiveness of each intervention combination.
Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

No masking was performed. The study is open-label, and neither participants nor investigators were blinded to group assignment due to the nature of the intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Exercise Group

Participants in this arm will receive a structured exercise program supervised by a physiotherapist, combined with posture education using an illustrated poster and regular standing advice. The exercise program consists of progressive abdominal and lumbar strengthening exercises performed 3 times per week for 12 weeks, with each session lasting approximately 20 minutes.

Group Type EXPERIMENTAL

Exercise

Intervention Type BEHAVIORAL

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.

Education

Intervention Type BEHAVIORAL

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.

Advice

Intervention Type BEHAVIORAL

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.

Education Group

Participants in this arm will receive posture education supported by an illustrated poster and regular standing advice. No exercise program will be provided to this group.
