Outcome Measures

Primary Outcomes (2)

  • Subjectively perceived muscle fatigue changes as determined with a Visual Analogue Scale (VAS)

    Subjects will rate their subjectively perceived muscle fatigue prior and after the test battery by means of a Visual Analogue Scale (VAS). The VAS used for this study ranges from 0 (none) to 100 (strongly pronounced) points. Question: How would you describe your current muscle fatigue in your writing hand?

    1 experimental day

  • Subjectively perceived discomfort as determined with a Visual Analogue Scale (VAS)

    Subjects will rate their subjectively perceived discomfort in the writing hand prior and after the test battery by means of a Visual Analogue Scale (VAS). The VAS used for this study ranges from 0 (none) to 100 (strongly pronounced) points. Question: How would you describe your current discomfort in the writing hand?

    1 experimental day

Secondary Outcomes (9)

  • Muscle pain estimated as determined with a Visual Analogue Scale (VAS)

    1 experimental day

  • Handwriting speed as determined with a maze task (accuracy based)

    1 experimental day

  • Handwriting speed as determined with a maze task (speed and accuracy based)

    1 experimental day

  • Handwriting speed as determined with a dot in cycle task

    1 experimental day

  • Handwriting speed as determined with a fatigue task

    1 experimental day

  • +4 more secondary outcomes

Study Arms (2)

Intervention first arm

EXPERIMENTAL

Due to the counter-balanced design of this study all participants will experience both an interventional and a control period. Within the "intervention first arm" participants will be asked to execute the assessment trial / test battery with the intervention pen first. After a wash-out period, the participants will execute the same assessment trial / test battery with the control pen.

Other: Ergonomic handwriting pen

Control first arm

EXPERIMENTAL

Due to the counter-balanced design of this study all participants will experience both an interventional and a control period. Within the "control first arm" participants will be asked to execute the assessment trial / test battery with the control pen first. After a wash-out period, the participants will execute the same assessment trial / test battery with the intervention pen.

Other: Ergonomic handwriting pen

Interventions

An ergonomic handwriting pen called AWP-pen designed to reduce perceived muscle fatigue, finger tip pressure and discomfort during handwriting activities.

Masking Details
Participants will be informed that the effect of the handwriting pen design on different physiological parameters will be investigated within the study. Although participants know that they will execute the test battery twice with two different handwriting pens, they will receive no information on which of the pens will be the intervention of interest (intervention pen). To realize an efficient masking process, control pens will be exclusively created for the study. Control pens will be made of the same material and will contain cartridge. They will only differ in design.
