ABSTRACT

 

Medical compression garment functions by exerted interface pressure between the fabric and skin. Yet, none of the previous studies have determine the pressure level of Lycra based orthosis. The current work aimed to determine the pressure level of Lycra orthosis at different postures in children with CP. Five (5) children with CP were recruited. Each were given a custom made Lycra orthosis. Two Tekscan medical sensor were placed over lateral side of upper garment and pants. The pressure was recorded when the child was in sitting, sit-to-stand (STS) and standing postures. There are significant differences of the interface pressure between each children, at different postures. The highest pressure recorded over upper garment is 122 mmHg and 120 mmHg over pants, both during sitting position. Overall, the Lycra orthosis exerted highest pressure over top garments than pants during sitting position.

 

Keywords: Interface pressure; lycra; orthosis; posture; rehabilitation

 

 

ABSTRAK

 

Pakaian mampatan perubatan berfungsi dengan memberikan tekanan antara muka antara fabrik dan kulit. Namun, tiada kajian terdahulu yang mengenal pasti tahap tekanan Likra berasaskan ortosis ini. Kertas ini bertujuan untuk mengenal pasti tahap tekanan Likra ortosis untuk postur berbeza pada kanak-kanak dengan CP. Lima (5) orang kanak-kanak dengan CP telah dipilih. Setiap seorang telah diberikan Likra ortosis yang dijahit tempah. Dua penderia perubatan Tekscan telah diletakkan pada sisian bahagian atas pakaian dan seluar. Tekanan direkodkan semasa kanak-kanak itu berada pada postur duduk, duduk untuk berdiri (STS) dan berdiri. Terdapat perbezaan yang signifikan pada tekanan antara muka antara kanak-kanak, pada postur yang berbeza. Tekanan paling tinggi yang direkodkan pada pakaian adalah 122 mmHg dan 120 mmHg pada seluar, kedua-duanya pada posisi duduk. Secara keseluruhannya, Likra orthosis memberikan tekanan tinggi pada pakaian daripada seluar dalam posisi duduk.

 

Kata kunci: Likra; ortosis; pemulihan; postur; tekanan antara muka
