What this trial studies

This observational study aims to investigate the performance differences in standardized motor skill tests among healthy women aged 20-24, based on their handedness. Participants will undergo the Nine Hole Peg Test, Purdue Pegboard Test, and Box and Block Test, with the unique approach of testing right-handed individuals as if they were left-handed and vice versa. The study seeks to determine if separate normative data for right-handed and left-handed individuals is necessary. Data will be collected in a single session after informed consent and a brief health questionnaire.

Who should consider this trial

Good fit: Ideal candidates are healthy women aged 20 to 24 who are native Czech speakers.

Not a fit: Patients with upper limb pathologies or conditions affecting dexterity will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate assessments of motor skills by establishing tailored normative data for different handedness.

How similar studies have performed: While the approach of examining handedness in motor skill testing is not widely explored, similar studies have shown the importance of considering laterality in motor assessments.
