Purpose:
Research on gross motor proficiency (GMP) in people with hemophilia is inconsistent, limiting treatment and wellness recommendations. This exploratory study used a norm-referenced assessment to measure GMP and explore relationships with hemophilia-specific parameters.
Methods:
Investigators collected demographic data, hemophilia type, severity, current management, and history of target joint(s) on 45 males with hemophilia, aged 4 to 21. Measurements included range of motion and subtests from the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2), which were compared with age- and sex-matched normative data using scale and standard scores.
Results:
The cohort scored at normative values or higher for BOT-2 subtests. Odds of scoring below average were increased in participants with obesity or target joints. No statistical associations were found between hemophilia type, severity, or current management and GMP.
Conclusions:
A diagnosis of hemophilia did not affect GMP, though patients with elevated body mass index or a target joint may be at greater risk of impaired motor proficiency.
