Task-Specific Training to Improve Sitting in a Child With Severe Postural Impairments: A Single-Subject Design

Area of Science:

• Pediatric rehabilitation
• Neurodevelopmental disorders
• Motor control research

Background:

• 16p11.2 deletion syndrome is associated with severe postural impairments.
• Developing sitting skills is crucial for motor development and functional independence in young children.
• Traditional interventions may not fully address the complex postural needs in this population.

Purpose of the Study:

• To evaluate a task-specific training model for improving sitting.
• To assess the efficacy of tailored trunk support and incrementally challenging reaching activities.
• To determine the potential for long-lasting improvements in sitting function.

Main Methods:

• A single-subject AB design with follow-up was employed.
• Intervention involved 15 sessions of tailored trunk support and reaching practice over 5 weeks.
• Outcomes measured included the Segmental Assessment of Trunk Control (SATCo) and Gross Motor Function Measure (GMFM) sitting dimension.

Main Results:

• Baseline scores on SATCo and GMFM remained stable.
• Significant trend changes were observed from baseline to intervention and follow-up.
• Independent sitting skills emerged post-intervention.

Conclusions:

• Task-specific training, individualized to the child's abilities, can enhance sitting function.
• Systematic progression of trunk support and reaching practice is key.
• The intervention demonstrated potential for promoting long-lasting sitting abilities.
