Objectives: Low back pain (LBP) is a common musculoskeletal disorder and prolonged sitting often aggravates LBP. A novel saddle chair, which facilitates less hip flexion while sitting on an unstable base has been developed. This study will compare lumbar posture on this novel saddle chair with a standard laboratory chair.
Design: Twelve (7 F, 5 M) pain-free participants will recruit from the local community. All participants will provide writ inform consent. Participants will age over 18 years, will not pregnant, had no LBP in the last two years, no previous spinal surgery, no current pain medications and will not undertaken previous postural control training. All participants will ask with two chair and postural data will collect using a electrogoniometer. Lumbar flexion/extension will measure with electrogoniometry with two chair.
Setting and conduct: Lumbar posture will measure with electrogoniometry method and were analyzed using paired t-tests. Postural data will collect using an electrogoniometer. Lumbar flexion/extension will measure with electrogoniometry with two chair.
Participants including major eligibility criteria: Twelve (7 F, 5 M) pain-free participants will recruit from the local community. All participants will provide writ inform consent. Participants will age over 18 years, will not pregnant, had no LBP in the last two years, no previous spinal surgery, no current pain medications and will not undertaken previous postural control training.
Intervention: Intervention in this study will the use of saddle chair and common chair. Intervention was provided for each person, with a saddle chair and common chair at the during electrogoniometry test.
Main outcome measures: Compare the lumbar posture of this novel saddle chair with a standard backless laboratory chair during a microscope task.
