2021, Journal of Bodywork and Movement TherapiesInfluence of Forward Head Posture on Cervicocephalic Kinesthesia and Electromyographic Activity of Neck Musculature in Asymptomatic Individuals
2020, Journal of Chiropractic MedicineCitation Excerpt :In the present study, the EMG activity of the UT and SCM muscles was found to be significantly increased in the FHP group relative to the control group both at rest and during activity. Forward head posture with rounded shoulders due to adoption of poor sitting posture for longer durations has been found to be common in the young population as a result of prolonged use of smartphones and computers.63,64 Sitting with a forward head inclination involves a combination of lower cervical flexion, upper cervical extension, and anterior shoulder position, leading to lengthening and weakness of deep cervical flexors and shortening of deep cervical extensors.40
Effects of scapular retraction/protraction position and scapular elevation on shoulder girdle muscle activity during glenohumeral abduction
2019, Human Movement ScienceCitation Excerpt :Noteworthy, scapular protraction occurs through a summation of scapular abduction, internal rotation, and anterior tilt, which are all secondary to the action of pectoralis minor (Neumann, 2010). Moreover, previous research studies on scapular kinematics highlighted that protracted scapular position, secondary to slouched body posture and rounded shoulder posture, led to a significant increase of scapular anterior tilt and internal rotation (Finley & Lee, 2003; Thigpen et al., 2010). Given that, we may assume that protracted scapular position is associated with a shortening in pectoralis minor length.
