The Effectiveness of the Logic Back™Support in Promoting a Comfortable Neutral Low Back Position, Reduced Muscular Effort, Improved Performance, and Decreased Postural Shifts in Seating.
Back pain and chair use are the second most important health factors for the aging workforce. Besides personal suffering, postural discomfort in the workplace reduces performance and productivity, both of which can be improved by raising comfort levels. In an attempt to improve comfort and reduce injury risk, ergonomic chairs are commonly equipped with lumbar supports in an attempt to support a "neutral" spine. However, people often alter their position when such a device is in place as they arch their back to conform to it. The Logic Back support offers a simple means to alter posture and reduce associated strain on the lower back during seated tasks by supporting the "Effortless Neutral Position" or the natural curvature of the low back. Although it has been used clinically by many practitioners, its effectiveness has yet to be shown by scientific study. The current work will help to understand if and why the Logic Back is effective and how it can become a low-cost solution to reduce the discomfort of those suffering from low back pain.
The purpose of this study is to determine the effectiveness of the Logic Back and the "Effortless Neutral Position" in improving comfort and functional performance during seated tasks, as compared to a standard, ergonomic chair.
