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.
