Study of Thoracic and Lumbar Spine Kinematics When Using Tipton Chair: A Repeated-measures Study in Healthy Young Adults

Objective: The effectiveness of the Tipton chair on thoracic and lumbar spine students was evaluated in straight upright position careful study postures. Materials & Methods: This performed 30 (20 women 10 men) who had no history musculoskeletal disorders. Evaluation changes angles spinal using an electrogoniometer normal two postures study. participants were each posture for five minutes. Considering resting time questionnaire completion, took minutes person. data recorded by analyzed through repeated measures statistical test system usability scale (SUS) paired t-test SPSS software, version 25. Results: mean range sagittal plane showed that variable type not significant (P=0.072), but (P=0.013). Also, regarding change lateral flexion, interaction (P=0.048) with (P=0.003) a difference. difference about 28% reduction flexion 10% compared to chair. While (P=0.705). extension 16% 43% (P=0.162) did have differences. study's results also both variables (P=0.009). reduced Analysis SUS scores chairs between these (P=0.000). In addition, average 78.6 65.9 chair, which shows increase 19%. Conclusion: present could reduce body spine. indicated user satisfaction level is higher than men. It can be due anthropometric dimensions
