Insights
High repetition therapy is feasible for children with cerebral palsy, showing variability but linking more repetitions to better hand function outcomes. This highlights repetition rate as a key factor in pediatric rehabilitation.
Area of Science:
- Pediatric Rehabilitation
- Neurorehabilitation
- Motor Learning
Background:
- Feasible repetition rates in pediatric upper extremity rehabilitation remain largely unknown.
- Understanding these rates is crucial for optimizing therapeutic interventions for children with conditions like cerebral palsy.
Purpose of the Study:
- To examine the actual repetition rates achieved during pediatric upper extremity rehabilitation.
- To investigate the impact of these repetition rates on functional outcomes in children.
Main Methods:
- Fifty-five children with unilateral cerebral palsy due to perinatal stroke participated.
- They underwent Constraint-Induced Movement Therapy (CIMT) and Bimanual Therapy, with repetitions documented over 5 days.
- Outcomes measured included the Assisting Hand Assessment (AHA), Jebsen Taylor Test of Hand Function (JTTHF), and Box and Block Test (BBT).
Main Results:
- Average repetition rates were 365 ± 165/hour during CIMT and 285 ± 103/hour during Bimanual Therapy.
- Higher repetition rates correlated with better baseline function, younger age, and improved motor skills.
- Increased repetitions were associated with significant improvements in the AHA and BBT scores.
Conclusions:
- High-repetition therapy is feasible for school-aged children with perinatal stroke, though individual variability exists.
- Repetition rates are a clinically important, measurable, and potentially modifiable factor influencing rehabilitation outcomes.
- These findings underscore the significance of quantifying and optimizing repetition counts in pediatric upper extremity therapy.
Aims:
In pediatric upper extremity rehabilitation, feasible repetition rates are unknown. Our objectives were to examine repetition rates during rehabilitation and their impact on outcomes.
Methods:
Children with unilateral cerebral palsy due to perinatal stroke (n = 55, median 10 y 7 mo, 30 males) received Constraint-Induced Movement Therapy (CIMT) followed by Bimanual Therapy, each for 5 days. Repetitions were documented during one-on-one therapy (1.5 h/day). Outcomes included the Assisting Hand Assessment (AHA), Jebsen Taylor Test of Hand Function (JTTHF), and Box and Block Test (BBT). Means and standard deviations for motor outcomes and frequencies for repetition rates were calculated. Factors associated with repetition rates and outcome change were explored using standard linear regression.
Results:
Repetitions/hour averaged 365 ± 165 during CIMT and 285 ± 103 during Bimanual Therapy. Higher repetition rates were associated with higher baseline function by older age, a main effect of younger age, and improving motor skill (p < .05). Higher repetition rates corresponded with improvement of the AHA and BBT (p < .05, standardized ß = 0.392, 0.358).
Conclusions:
Results suggest high repetition therapy is feasible in school-aged children with perinatal stroke, albeit with high individual variability. Multiple associations between repetition rates and baseline function and change point to the clinical importance of this measurable and potentially modifiable factor.
