Condition

Non-specific neck, upper back and low back pain

Intervention

Office workers in the study will be randomised into 2 groups: an exercise group and a control group. The exercise intervention will include stretching and endurance exercises. The stretching exercises will consist an auto stretching to neck extensor, pectoralis and hip flexor muscles. Each muscle will be stretched once by holding for 30 seconds. The endurance exercise for neck flexor, trunk extensor, multifidus and transversus abdominis muscles will be performed. Each muscle will be exercised for 10 repetitions. The 1 minute rest will be allowed between muscles. The intensity of endurance exercise will be adjusted every 2 months by increasing the number of repetition and reduction of rest time. Participants in the exercise group will performed stretching exercise twice a day at 10am and 14pm for 5 times per week for 12 months and endurance exercise twice per week on Wednesday and Sunday for 12 months. For the control group, participants will be asked not to change their current activity or begin an exercise program.
