The Bead Maze Hand Function Test for Children.

Area of Science:

• Pediatric occupational therapy
• Movement science
• Biomedical engineering

Background:

• Objective assessment of pediatric hand function is crucial for evaluating movement quality.
• Existing methods may lack sensitivity or objectivity in quantifying fine motor skills.
• A novel, toy-based approach can enhance engagement and data collection in children.

Purpose of the Study:

• To evaluate the psychometric properties of the Bead Maze Hand Function (BMHF) test.
• To determine the influence of participant age and task complexity on BMHF test measures.
• To establish the reliability and validity of the BMHF test for pediatric hand function assessment.

Main Methods:

• A cross-sectional, observational study involving 23 typically developing children (ages 4-15).
• Participants performed the sensor-equipped BMHF test and the Box and Block test with both hands.
• Linear mixed-effects models analyzed force and time data; intraclass correlation coefficients assessed interrater reliability.

Main Results:

• Total force and completion time decreased with increasing age and task complexity.
• Total force measures were more sensitive to variations in task difficulty.
• The BMHF test demonstrated excellent interrater reliability and moderate concurrent validity with the Box and Block test.

Conclusions:

• The sensor-equipped Bead Maze Hand Function (BMHF) test is a sensitive and reliable tool for objectively assessing pediatric hand function.
• The test effectively quantifies movement quality, with sensitivity to age and task complexity.
• This toy-based assessment offers a promising method for clinical and research applications in pediatric occupational therapy.
