Clinical Trial Summary

he objective of this study is to examine the influence of additional axial load abd body position on cervical motor control in young healthy adults.

Description:

Motor control of the cervical spine is impotent for responsible for maintaining balance during daily living activities and to withstand external loads. Stabilization-aspects of the cervical spine is very complex, passive (ligaments, joint capsule and the skin and active (muscles), and neurological subsystems are involved. Mostly proprioceptive testing and exercises like head and neck position sense testing and re-training have been an integral part of rehabilitation. Another method to evaluate spinal motor control is the assessment of spinal stiffness. The main objective of this study is to explore the effects of additional axial loading on motion control in healthy individuals. Does the motor control of the cervical spine in healthy subjects change with additional axial load or body position? A better understanding of spinal stiffness and neck position sense leads to novel insights into spinal cervical stabilization mechanisms.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of neck joint-position error between differnent weight conditions	Joint-position error will be will be assessed with Sensomove. It consists of the 3D senscoordination sensor, an adjustable headband, and basic software for motion feedback of head movements. The change of Joint-Position Error with and without additional axial load will be assessed.	20 minutes group cervical stiffness
Primary	Change of neck joint-position error between two sitting positions	Joint-position error will be will be assessed with Sensomove It consists of the 3D senscoordination sensor, an adjustable headband, and basic software for motion feedback of head movements. The change of Joint-Position Error with axial load (3kg) between two sitting positions will be assessed.	20 minutes group Dynamic cervical stability
Primary	Change of neck range of motion between different weight conditions	Range of motion will be will be assessed with Sensomove It consists of the 3D senscoordination sensor, an adjustable headband, and basic software for motion feedback of head movements. The change of Rage of motion with and without additional axial load will be assessed.	20 minutes group cervical stiffness
Primary	Change of spinal stiffness between different sitting positions and loading conditions	The device measures tissue compliance according to the concept of impulse-response. A force of exact 20 Newton will be applied from the device to the process spinous. The expected impulse-response (result) will be between 20 Newton and 40 Newton. The change of spinal stiffness due sitting position and loading will be assessed.	20 minutes group cervical stiffness
Secondary	Pain during measuring	The visual analogue scale will be used to quantify pain, if any of the measurements is painful. The participant is asked to rate his pain intensity on a straight line (100mm) with two endpoints.	2 minutes
Secondary	Self-administered neck mobility	Self-administered neck mobility questionnaire is a self-administered questionnaire that uses visual analog scales to measure pain-free active rage of motion for all neck movements. The patient is asked to place a mark on a 100 mm line (0 mm = "no movement possible" and 100 mm = "as far as possible"). The total score is the sum of the individual scores (min. score (600) = no restrictions and max. score (0) = total restriction)	4 minutes
Secondary	Neck Disability Index	The Neck Disability Index is a self-report questionnaire with 10-items: pain intensity, personal care, lifting, work, headaches, concentration, sleeping, driving, reading, and recreation. The response to each item is rated on a 6-point scale from 0 (no disability) to 5 (complete disability). The numeric responses for each item are summed for a total score ranging between 0 and 50.	4 minutes
