“…Cervical afferent input is believed to importantly contribute to postural balance [ 17 , 18 ] and eye movement control [ 19 ]. Abnormal cervical afferent input is suggested to cause disturbances in the cervico-collic and cervico-ocular reflexes, consequently negatively influencing eye movement control, especially in neck torsion maneuvers [ 20 , 21 ]. Same trends of poorer performance during neck torsion maneuvers have been proposed for postural balance tasks [ 22 ] but their relationship to afferent input reflected in dynamic cervicocephalic kinesthesia has not yet been measured in neck pain patients.…”

Cervical afferent input is believed to affect postural balance and oculomotor control in neck pain patients, but its relationship to cervicocephalic kinesthesia, describing movement sense, has not yet been studied. The aim of this study was to analyze the relationship of two aspects of cervicocephalic kinesthesia to postural balance and oculomotor control in neck torsion positions. Forty-three idiopathic neck pain patients referred from orthopedic outpatient clinics and forty-two asymptomatic controls were enrolled in the study. A force plate was used to measure center-of-pressure movements during parallel stances under neutral and neck torsion maneuvers. Video-oculography was used to assess eye movements during smooth pursuit neck torsion test (SPNTT), while kinesthetic awareness was measured using the Butterfly test and head-to-neutral relocation test. Multiple regression was used to describe relationships between tests. Body sway in the anterior–posterior direction was related to Butterfly parameters but less to the head-to-neutral test. A medium relationship between Butterfly parameters and gain during SPNTT, with less SPNT-difference, was observed, but not for the head-to-neutral test. It can be concluded that specific aspect of neck kinesthetic functions (i.e., movement sense) importantly contributes towards oculomotor and balance control, which is more evident under neck torsion positions in neck pain patients, but is less pronounced in asymptomatic individuals.

“…Cervical spine proprioception has been shown to influence oculomotor control [ 72 ], and impairment can produce sensorimotor disruption, affecting visual functions influenced by the cervical spine [ 73 , 74 ]. Treatments focusing on improving proprioceptive input from the cervical spine and improving head−eye coordinative movements have been observed to improve saccadic performance [ 75 , 76 ].…”

Quantifying saccadic eye movements can assist in identifying dysfunctional brain networks in both healthy and diseased people. Infrared Oculography is a simple and non-invasive approach to capturing and quantifying saccades, providing information that might aid in diagnosis and outcome assessments. The effect of spinal manipulation on quantified saccadic performance parameters has not been fully studied despite known post-manipulative effects on the brain and brainstem regions controlling them. This case study investigates spinal manipulation’s immediate and long-term effects on saccadic eye movements by quantifying the saccades of a male patient diagnosed with post-concussion syndrome. The patient performed horizontal saccades that were quantified before and immediately following cervical spinal manipulation both at the case study’s start and following a 2-week interim, during which the subject received six manipulative treatments. Immediate and long-term post-manipulative effects were observed, and the results revealed various post-manipulative effects across all quantified parameters in addition to between right and leftward saccades. The immediate post-manipulative effect was greatest at the case study’s onset, while the long-term right and leftward saccadic symmetry were most affected. The observations in this case study demonstrate that cervical spinal manipulation influences saccadic eye movements, providing new insights into its central neurological effects and therapeutic applications beyond its most commonly known use in pain management. More importantly, it encourages scientists to undertake further clinical investigations on wider scales.
