Insights
Pressure biofeedback (PB) combined with occupational therapy (OT) significantly improved motor skills in children with Developmental Coordination Disorder (DCD). This non-invasive approach enhanced manual dexterity, fine motor precision, and visuomotor coordination, offering lasting benefits.
Area of Science:
- Neurodevelopmental Disorders
- Rehabilitation Technologies
- Pediatric Occupational Therapy
Background:
- Developmental Coordination Disorder (DCD) impacts manual dexterity (MD) and fine motor skills (FMS) in children.
- Pressure biofeedback (PB) offers a non-invasive method for real-time motor learning feedback.
- The efficacy of combining PB with occupational therapy (OT) for DCD requires further investigation.
Purpose of the Study:
- To investigate the effects of PB combined with OT on MD and FMS in children diagnosed with DCD.
- To quantitatively assess improvements in motor coordination, fine motor precision, and visuomotor integration.
Main Methods:
- A single-blinded, randomized controlled trial involving 40 children (aged 5-10 years) with DCD.
- Intervention group received PB + OT; control group received OT alone.
- Evaluations included the DCD Questionnaire (DCD-Q), Bruininks-Oseretsky Test of Motor Proficiency (BOT-2), PB pattern tracking (RMSE for precision, CC for visuomotor integration).
Main Results:
- The PB+OT group showed significantly greater improvements in DCD-Q, BOT-2, RMSE, and CC scores compared to the OT-alone group.
- Improvements included enhanced manual dexterity, proprioception, fine motor skills, and visuomotor coordination.
- Sustained gains in visuomotor coordination were observed at follow-up, confirmed by repeated measures ANOVA.
Conclusions:
- Pressure biofeedback is a practical and quantitative intervention for improving MD and FMS in children with DCD.
- Integrating PB with OT leads to significant and lasting enhancements in motor coordination and related functions.
- Biofeedback presents a viable, non-invasive, and engaging option for pediatric neurorehabilitation within family-centered care models.
Abstract:
Developmental Coordination Disorder (DCD) is a neurodevelopmental condition affecting manual dexterity (MD) and fine motor skills (FMS). Pressure biofeedback (PB), a noninvasive tool providing real-time feedback, may enhance motor learning. This study examined the effects of PB combined with occupational therapy (OT) on MD and FMS in children with DCD. In this single-blinded, randomized controlled trial, 40 children aged 5-10 years with DCD were assigned to an intervention group (PB + OT) or a control group (OT alone). The Developmental Coordination Disorder Questionnaire (DCD-Q) provided a subjective evaluation of motor coordination, including FMS and proprioception. MD was objectively measured by the manual dexterity subtest of the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2). Pressure biofeedback (PB) pattern tracking quantified fine motor precision and proprioceptive regulation using Root Mean Square Error (RMSE) and visual-motor integration using the Correlation Coefficient (CC). Post-intervention, the intervention group showed significantly more improvements than controls in DCD-Q, BOT-2, RMSE, and CC scores. DCD-Q and BOT-2 scores increased (p < 0.05), indicating enhanced manual dexterity, including proprioception and fine motor skills. RMSE decreased (p < 0.001), reflecting improved fine motor precision and proprioceptive regulation. CC scores improved post-intervention (p = 0.011) and remained higher at follow-up (p < 0.001), demonstrating sustained visuomotor coordination gains. Repeated measures ANOVA confirmed significant time and group effects (p < 0.05), supporting lasting motor improvements. PB is a practical, quantitative intervention for enhancing MD and FMS in children with DCD. Integrating PB with OT led to significant and sustained improvements in motor coordination, visuomotor integration, proprioceptive function, and handwriting performance. These findings support biofeedback as a non-invasive and engaging approach for pediatric neurorehabilitation, aligning with family-centered, non-pharmacological care models.
