Trapezius Muscle Electromyographic Activity in Lawn-Mower Exercise: Standing Versus Quadruped.

Context: In shoulder rehabilitation, exercises that reduce upper trapezius (UT) activity and optimize the trapezius muscle activation rate reduce the symptoms of shoulder pathologies. One such exercise, the lawn-mower (LM) exercise, is frequently used in scapular rehabilitation protocols due to its multijoint, multiplanar, and kinetic chain-based nature. Design/Objective: This study aimed to compare trapezius muscle activation levels and ratios during the LM exercise in standing and quadruped positions through a randomized controlled trial.

Investigation of muscle activation during kinetic chain based exercises in individuals with and without forward head posture.

Background: The Band Pull-Apart (BPA) exercise is used to strengthen the periscapular muscles. It was recently stated that the lower extremity and trunk movements should be included in the shoulder rehabilitation programs to optimize an effective energy transfer throughout the kinetic chain.

Objective: The aim of this study is to investigate the effects of kinetic chain based BPA exercise on the muscle activations of the sternocleidomasteideous (SCM) and the trapezius muscles in individuals with and without forward head posture (FHP).

Muscle Activation Differences During Eccentric Hamstring Exercises.

Background: The hamstring muscles play a critical role in the prevention of lower limb injuries. However, it is still unclear which exercises are more effective in terms of muscle activation.

Hypothesis: In healthy individuals, there are differences between muscular activations of the biceps femoris (BF), semitendinosus (ST), and semimembranosus (SM) muscles during eccentric hamstring exercises.
