STUDY DESIGN Experimental study. OBJECTIVES To compare two devices for measuring cervical range of motion, a three-dimensional ultrasound motion device (Zebris) and a gravity-reference goniometer (Myrin). SUMMARY OF BACKGROUND DATA Assessment of cervical range of motion is used to evaluate the effect of different treatments, determine impairment, and(More)
The ability to reproduce a specified head-on-trunk position can be an indirect test of cervical proprioception. This ability is affected in subjects with neck pain, but it is unclear whether and how much pain or continuous muscle contraction factors contribute to this effect. We studied the influence of a static unilateral neck muscle contraction task (5(More)
STUDY DESIGN Exploratory experimental design. OBJECTIVES To examine primary and coupled cervical movements, and to study the effects of age, gender, and body mass index in a "neck-healthy" population. These data could serve as a basis for future interventions and to assess normal variations. SUMMARY OF BACKGROUND DATA Cervical movements are(More)
PURPOSE To explore musculoskeletal findings in patients with cervicogenic dizziness and how these findings relate to pain and dizziness. To study treatment effects and long-term symptom progress. METHOD Twenty-two patients (20 women, 2 men; mean age 37 years) with suspected cervicogenic dizziness underwent a structured physical examination before and(More)
UNLABELLED We investigated test to retest reliability and intraindividual variability of Romberg ratios in quiet stance posturography. Thirty-six healthy young adults (17 males, 19 females aged 15-38 years) were divided into 3 groups with different time-intervals between consecutive trials (20 min, 3h and 24h respectively). Each group performed 5(More)
The aim was to investigate the relative importance of cervical proprioception compared to vestibular input for head movements on trunk. Subjects with bilateral vestibulopathy (n = 11) were compared to healthy controls (n = 15). We studied their ability to move the head accurately to reproduce four specified target positions in the horizontal yaw plane(More)
OBJECTIVE To investigate the reproducibility of thermal thresholds, as measured by repeated quantitative sensory testing (QST) in healthy controls, and to asses if temperature sensitivity differs between healthy controls and a cohort of patients with persistent pain. SUBJECTS A total of 54 healthy controls were compared with 25 consecutive patients(More)
OBJECTIVES Recent studies based on self-assessed data on exposure and outcome suggest a negative association between poor health before neck injury and recovery. Our aim was to study actual healthcare consultation and work disability before and after neck injury (whiplash). DESIGN Cohort study with matched references studied prospectively and(More)
The proprioceptive, visual and vestibular sensory systems interact to maintain dynamic stability during movement. The relative importance and interplay between these sensory systems is still not fully understood. Increased knowledge about spatial perception and postural orientation would provide better understanding of balance disorders, and their(More)
