Abstract

Background: Children are involved in many activities in sitting position such as reading, writing, playing and other related activities for a long duration (4-5 hrs) during day, The aim of the study to determine the efficacy of inclined seat surface on postural adjustments in sitting position during forward reaching in normal children. Fifteen Typically developing children were studied in three conditions: sitting with the seat surface oriented horizontally, sitting with the seat surface tilted 15 degrees forward and 15 degree backward.

Methods: postural muscle activity were recorded using surface electromyograms during reaching in the 3 conditions in addition to modified paediatric functional reaching test is done to determine which seat surface reflect the maximum postural control ability and stability in the 3 condition.

Results: The result suggest that in terms of postural muscle activity, backward inclined associated with more muscle activity than forward inclined surface and horizontal surface position while forward inclined associated with less muscle activity and more postural control ability in terms of modified paediatric reaching test.

Conclusion: In children who are typically developing, forward inclined seat surface is best position as it is associated with less postural activity and more postural control ability and stability during forward reaching.
