Abstract
Abstract Objectives Patients with idiopathic adult‐onset cervical dystonia ( CD ) experience an abnormal head posture and involuntary muscle contractions. Although the exact areas affected in the central nervous system remain uncertain, impaired functions in systems stabilizing the head and neck are apparent such as the somatosensory and sensorimotor integration systems. The aim of the study is to investigate cervical sensorimotor control dysfunction in patients with CD . Material and Methods Cervical sensorimotor control was assessed by a head repositioning task in 24 patients with CD and 70 asymptomatic controls. Blindfolded participants were asked to reposition their head to a previously memorized neutral head position ( NHP ) following an active movement (flexion, extension, left, and right rotation). The repositioning error (joint position error, JPE ) was registered via 3D motion analysis with an eight‐camera infrared system ( VICON ® T10). Disease‐specific characteristics of all patients were obtained via the Tsui scale, Cervical Dystonia Impact Profile ( CDIP ‐58), and Toronto Western Spasmodic Rating Scale. Results Patients with CD showed larger JPE than controls (mean difference of 1.5°, p < .006), and systematically ‘overshoot’, i.e. surpassed the NHP , whereas control subjects ‘undershoot’, i.e. fall behind the NHP . The JPE did not correlate with disease‐specific characteristics. Conclusions Cervical sensorimotor control is impaired in patients with CD . As cervical sensorimotor control can be trained, this might be a potential treatment option for therapy, adjuvant to botulinum toxin injections.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
