This study examined the acute effects of inhibitory Kinesiotaping (iKt) on the activity ratio of the lower trapezius (LTr), scapular posterior tilt (PT), and total shoulder proprioceptive variability (E).
The intricate control of the shoulder girdle involves the interplay among scapular muscles, scapulohumeral kinematics, and proprioceptive signals from the shoulder joint. Kinesiotaping, used by therapists, facilitates, or inhibits activities of treated and non-treated muscle. This study examined the acute effects of inhibitory Kinesiotaping (iKt) on the activity ratio of the lower trapezius (LTr), scapular posterior tilt (PT), and total shoulder proprioceptive variability (E). Twenty healthy participants underwent iKt on the dominant upper trapezius. Participants were blindfolded and performed five active shoulder position sense at 100° (proprioceptive tasks). Simultaneous recordings of both the lower trapezius and serratus anterior activity, along with scapulohumeral kinematics, were conducted in both frontal and scapular planes under iKt and no-tape conditions.
