Poor chair designs to be blamed for neck and back pain in school students

Chair design in schools ...

"Poor chair designs are partially to be blamed for neck and back pain in high school students, an Australian research has revealed

Griffith University researcher Neil Tuttle found that lack of good seating is behind majority of the back and neck pain experienced by students.

For the study, he designed bumograph, a device to measure the shape buttocks make when seated.

The device has 96 sensors, which are used to measure the contour of seated buttocks, and it replaces the seat of the chair with high-density foam.

Tuttle found that students' gender affected the seated buttock shape more than other factors like weight, height or posture.

While males had a deeper narrower contour, female students had a broader, flatter shape.

"If the seat width and seat height of an armchair were made to fit the average dimensions of a population, the chair would be unusable for most of the population," ABC Online quoted Tuttle, as saying.

"The contours of the front and back portions of the seat influence sitting posture and the whole of the seat contour affects seat comfort," he says.

"The contour of the seat affects the two most important factors influencing the comfort of the chair,' he added.

Tuttle says an immediate solution to back and neck pain in students is for school authorities to buy adjustable and comfortable chairs."    (Continued via Yahoo! India News)    [Ergonomics Resources]
