Lower Extremity And Trunk Electromyographic Muscle Activity During Performance Of The Y-Balance Test On Stable And Unstable Surfaces., Navpreet Kaur, Kunal Bhanot, Germaine Ferreira

Physical Therapy Collection

Background: The Star Excursion Balance Test (SEBT) has been used as a rehabilitation exercise. To improve its efficacy, efficiency, and method variations, the Y-Balance Test (YBT) with anterior (A), posterolateral (PL), and posteromedial (PM) directions of the SEBT has been recommended. Electromyographic activity has been reported to change when the same task is performed on various surfaces.

Hypothesis/Purpose: To compare the EMG activity of trunk and LE muscles during the performance of the YBT on stable and unstable surfaces.

Study Design: Cross-Sectional study.

Methods: Healthy adults with no history of chronic ankle instability were recruited for the study. …

Muscle Activation Patterns During Movement Attempts In Children With Acquired Spinal Cord Injury: Neurophysiological Assessment Of Residual Motor Function Below The Level Of Lesion., Darryn A Atkinson, Laura Mendez, Natalie Goodrich, Sevda C Aslan, Beatrice Ugiliweneza, Andrea L Behrman

Physical Therapy Collection

Introduction: Characterization of residual neuromotor capacity after spinal cord injury (SCI) is challenging. The current gold standard for measurement of sensorimotor function after SCI, the International Society for Neurological Classification of Spinal Cord Injury (ISNCSCI) exam, seeks to determine isolated intentional muscle activation, however many individuals with SCI exhibit intentional movements and muscle activation patterns which are not confined to specific joint or muscle. Further, isolated muscle activation is a feature of the neuromuscular system that emerges during development, and thus may not be an appropriate measurement standard for children younger than 6.

Methods: We utilized neurophysiological assessment …

Hip And Trunk Muscle Activity During The Star Excursion Balance Test In Healthy Adults, Kunal Bhanot, Navpreet Kaur, Lori Thein Brody, Jennifer Bridges, David C. Berry, Joshua J. Ode

Physical Therapy Collection

CONTEXT: Dynamic balance is a measure of core stability. Deficits in the dynamic balance have been related to injuries in the athletic populations. The Star Excursion Balance Test (SEBT) is suggested to measure and improve dynamic balance when used as a rehabilitative tool.

OBJECTIVE: To determine the electromyographic activity of the hip and the trunk muscles during the SEBT.

DESIGN: Descriptive.

SETTING: University campus.

PARTICIPANTS: Twenty-two healthy adults (11 males and 11 females; 23.3 [3.8] y, 170.3 [7.6] cm, 67.8 [10.3] kg, and 15.1% [5.0%] body fat).

INTERVENTION: Surface electromyographic data were collected on …

Effect Of Stable And Unstable Surfaces On The Serratus Anterior Muscle Activation In A Kinetic-Chain Exercise Among Healthy Adults, Navpreet Kaur, Kunal Bhanot, Germaine Ferreira

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 …
