Brief Summary

The objective of this study is to explore the "vertical self-motion perception" on in healthy young individuals using an elevator as accelerator. Secondary aim is to explore the effects of repeated vertical acceleration on vertical vestibular sensibility.

Outcome Measures

Primary Outcomes (1)

• Change of Vertical Self-Motion Perception Reaction Time (VSMPT)

  The VSMPT reflects the time in which a person's ability to sense vertical acceleration. A Raspberry Pi 3 B+ with an inertial measurement unit (IMU) will measure the vertical acceleration of the elevator's acceleration. The subject will be asked to stop the stopwatch he/she feels acceleration / deceleration of the elevator ride. The reaction time and the duration of acceleration / deceleration will be measured. Data will be collected starting on the ground floor as the elevator travelled up to a stop at the higher floor (12 floors up). Thereafter the down ride will be measured.Five-elevator rides up and five down will be measured.

  Changes from before and after the elevator rides will be assessed. The assessments will be executed one minute before and after the trampoline intervention. One assessment will take 15 minutes.

Secondary Outcomes (2)

• Self-administered neck mobility assessment tool (S-ROM-Neck)

  5 minutes. At the start of the study and before the first elevator measurements the participants are asked to fill out the questionnaire.

• Dizziness handicap inventory (DHI)

  5 minutes. At the start of the study and before the first elevator measurements the participants are asked to fill out the questionnaire.

Study Arms (1)

Trampoline

EXPERIMENTAL

The participants will jump on a mini-trampoline for 30 seconds and then will have a 30 seconds break. This will be repeated 16 times. This resulted in a cumulative total intervention time of 8 minutes.

Diagnostic Test: Trampoline

Interventions

Trampoline DIAGNOSTIC_TEST

During trampoline training that participants undergo constant change of vestibular stimulation. This triggers deep proprioception as well as other sensory inputs. This trigger might affect strength, body stability, muscle coordinative responses, joint movement amplitudes and spatial integration
