Outcome Measures

Primary Outcomes (4)

• 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

• 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

• 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

• 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 Outcomes (3)

• Pain during measuring

  2 minutes

• Self-administered neck mobility

  4 minutes

• Neck Disability Index

  4 minutes

Study Arms (2)

Dynamic cervical stability

The participant is asked to move the head in 6 directions in a sitting position and 30° leaning backward sitting position; lateral flexion (left / right), flexion, extension, and rotation (left / right). Results are to be taken for each direction and random at each axial load-level (0 kg, 1kg, 2 kg, and 3 kg). In total 24 measurements. The duration of all measurement will be 60 minutes.

Other: axial load

Cervical Stiffness

The participant is asked to move the head in 4 directions; flexion, extension, and rotation (left / right). Joint-Position Error measurements will be executed in neutral sitting position. Additionally, stiffness will be measured in neutral sitting position and neutral sitting position with 45° cervical flexion. All measurements will be performed with 0 kg and 3 kg axal loading. In total 18 measurements.The duration of all measurement will be 60 minutes.

Other: axial load

Interventions
