Abstract

 Background and Aims: Lumbar pain and postural abnormalities are among the most important issues in the workplace. In the meantime, staffs with a static and steady state of work will be more likely to suffer. In case of proper solutions, these problems can be reduced and possibly eliminated. Therefore, the purpose of the present study was to examine the effect of six weeks of chair exercises on the kinematics variables during walking, physical structure, and pain among the staffs at Shahid Bahonar University of Kerman.
Materials and Method: A quasi-experimental study was carried out at Shahid Bahonar University of Kerman. A sample of 27 people including 10 males and 17 females (age: 40.81 ± 4.51 years, height: 164.15±8.47 centimeters, mass: 75.18 ± 6.75 kg) selected purposefully took part in the study. The step length, step width, and step frequency were measured using a 3D Motion Analysis system with 6 optoelectronic cameras and a recording frequency of 120 Hz. To measure lordosis, a flexible ruler was used and to measure pain, forward shoulder from a double quadrilateral and Nordic questionnaire was used. To analyze the data, dependent t-test was used at the significance level of P Results: The results revealed significant differences between pretest and posttest averages for these variables: stride length, step width, frequency step, back pain, shoulder lordosis, and shoulder forward. Also, the length of the step size increased in the post-test. The size of other variables, however, declined.
Conclusion: According to the results of the present study, chair exercises have a positive effect on the kinematic variables, the reduction of lumbar lordosis, and forward shoulder, as well as the reduction of the lumbar pain in the staffs. Accordingly, these exercises can be used to improve the kinematic variables, body structure, and pain relief in the lumbar region.
