Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: (1) Adults aged 18 to 55 years (the cutoff value was set to 55 to avoid the effects of aging on the tendons). (2) Individuals who do not currently have shoulder pain. (3) Individuals with no history of severe shoulder joint trauma. (4) Individuals with no history of rotator cuff tears (regardless of the degree). (5) Individuals with no history of shoulder surgery. (6) Individuals with no history of diseases that could potentially affect the tendons (e.g., metabolic diseases, autoimmune diseases). (7) Individuals who hold a valid driver's license.

Exclusion criteria

Exclusion criteria: (1) Individuals for whom continuing the driving simulator operation is deemed difficult due to simulator sickness or similar issues. (2) Individuals who are pregnant. (3) Individuals deemed unsuitable for participation in this study by the principal investigator.

Design outcomes
