Physical Therapy Collection

PURPOSE/HYPOTHESIS: The stabilizing action of the serratus anterior (SA) muscle is vital in maintaining proper scapulothoracic rhythm.^1,2 Poor activation of SA muscle could lead to many shoulder dysfunctions.^1,3 This warrants for exercises that are best to activate the SA muscle. Kinetic-chain recruitment during exercises has demonstrated increased SA activation due to the myofascial connections between various segments of the body.^4–6 Variation of surfaces during an exercise has been shown to alter the muscle recruitment patterns.^7–9 The primary purpose of this study was to determine if the unstable surface can influence SA muscle activity during the kinetic …
