“…Another finding was that the complaint foam support surface increased the movements of the lower body segments, e.g., the knee and hip movements proportionally more than shoulder and head movements, see table 2. These observations are in line with several previous reports showing that changed sensory information from vision and proprioception can have a major effect on postural control and the multi-segmented body movements (Kavounoudias et al 1999;Perry et al 2000;Kavounoudias et al 2001;Blackburn et al 2003;Vuillerme et al 2005).…”

Postural control ensures stability during both static posture and locomotion by initiating corrective adjustments in body movement. This is particularly important when the conditions of the support surface change. We investigated the effects of standing on a compliant foam surface using twelve normal subjects (mean age 26 years) in terms of: linear movements at the head, shoulder, hip and knee; EMG activity of the tibialis anterior and gastrocnemius muscles and torques towards the support surface. As subjects repeated the trials with eyes open or closed, we were also able to determine the effects of vision on multi-segmented body movements during standing upon different support surface conditions.As expected, EMG activity, torque variance values and body movements at all measured positions increased significantly when standing on foam compared with the firm surface.Linear knee and hip movements increased more, relative to shoulder and head movements while standing on foam. Vision stabilized the head and shoulder movements more than hip and knee movements while standing on foam support surface. Moreover, vision significantly reduced the tibialis anterior EMG activity and torque variance during the trials involving foam.In conclusion, the foam support surface increased corrective muscle and torque activity, and changed the firm-surface multi-segmented body movement pattern. Vision improved the ability of postural control to handle compliant surface conditions. Several essential features of postural control have been found from recording movement from multiple points on the body, synchronized with recording torque and EMG.

“…The contribution of cervical muscles to sensorimotor function has been emphasized with regards to the density of muscle spindles that reflect a well-developed proprioceptive system (Dutia, 1991;Boyd-Clark et al, 2002), and cervical muscles play a major role in motor control of the head and neck (Dutia, 1991;Peterson, 2004;Armstrong et al, 2008), eye movements (Karlberg et al, 1991), and bipedal posture during quiet standing (Vuillerme et al, 2005).…”

“…Neck muscle fatigue is reported to influence postural control and may disturb subjective postural reference. Neck extensor muscle fatigue increases body sway, in addition to changing body direction [14][15][16][17] . A study reported that after 5 minutes of intense contraction of approximately 35% of maximal voluntary contraction of the dorsal neck muscles the body sway increased during quiet standing 15) .…”

Abstract. [Purpose] This study investigated postural stability and visual vertical perception of healthy middleaged subjects before and after induction of dorsal neck muscle fatigue.[Subjects] Fourteen subjects (3 males, 11 females) were recruited from the community.[Methods] To induce neck extensor muscle fatigue, participants pushed their heads against a myometer. The average center of pressure (COP) displacement in the medial-lateral (ML) and anterior-posterior (AP) directions and average sway velocity were measured on a force platform, and the error in visual vertical perception was measured using the rod and frame test.[Results] The average COP displacement in the AP direction and average sway velocity were significantly different between before and after induction of neck muscle fatigue. No difference in the average COP displacement in the ML direction or errors in visual verticality perception was observed before and after neck muscle fatigue. [Conclusion] In the presence of visual input, dorsal neck muscle fatigue induced postural instability, but not visual vertical misperception. After isometric or repetitive neck extensor muscle contraction for a long period, taking a rest for a while before changing posture from sitting to standing is recommended for workers, to avoid an increase in postural sway in standing, which may lead to an accidental fall.
