Insights
Reliable assessment of upper extremity function in children with cerebral palsy (CP) is possible using the modified House Functional Classification (MHC) and Upper Extremity Rating Scale (UERS). These tools offer reproducible and efficient evaluation for clinicians.
Area of Science:
- Pediatric Rehabilitation
- Neurology
- Orthopedics
Background:
- Cerebral palsy (CP) significantly impacts upper extremity function and range of motion in children.
- Standardized and reliable assessment tools are crucial for effective clinical management of CP.
- Previous evaluations may lack consistency in busy clinical environments.
Purpose of the Study:
- To evaluate the hypothesis that upper extremity function and range of motion in children with CP can be reliably quantified in a clinical setting.
- To determine the inter- and intrarater reliability of the modified House Functional Classification (MHC) system.
- To assess the reliability of the Upper Extremity Rating Scale (UERS) for documenting upper extremity range of motion.
Main Methods:
- Sixty-five children with CP and upper extremity spasticity were evaluated.
- Occupational therapists and orthopedic surgeons independently assessed participants using the MHC and UERS.
- Inter- and intrarater reliability were calculated using intraclass correlation coefficients (ICCs) and weighted kappa values.
Main Results:
- The MHC demonstrated good to excellent interrater (ICC=0.94) and intrarater (ICC=0.96) agreement.
- The UERS showed good to excellent inter-rater (kappa 0.66-0.81) and intrarater (kappa 0.64-0.88) agreement.
- Both instruments proved reliable and reproducible in a clinical setting.
Conclusions:
- The modified House Functional Classification (MHC) system is a reliable tool for assessing upper extremity function in children with CP.
- The Upper Extremity Rating Scale (UERS) is a reliable instrument for documenting upper extremity range of motion in this population.
- These standardized instruments are efficient and can be effectively utilized by clinicians managing children with CP.
Abstract:
This study evaluated the hypothesis that upper extremity function and range of motion can be quantified reliably in children with cerebral palsy (CP) in a busy clinical setting. The specific aim was to determine the inter- and intrarater reliability of a modified House Functional Classification (MHC) system to evaluate upper extremity function and a standardized instrument to document upper extremity range of motion (Upper Extremity Rating Scale [UERS]). Sixty-five children with CP (43 males, 22 females, mean age 9y 2mo, SD 4y 1mo) with spasticity involving the upper extremity (quadriplegia n=22; hemiplegia n=36; diplegia n=7; Gross Motor Functional Classification System Levels I n=41, II n=6, III n=3, IV n=5, V n=10) were evaluated independently by occupational therapists and orthopedic surgeons using both instruments at several visits. Inter- and intrarater reliability were determined for both instruments by calculating measures of agreement (weighted kappa values and intraclass correlation coefficients [ICCs]). Interrater agreement (ICC=0.94) and intrarater agreement (ICC=0.96) on the MHC were good to excellent. Similarly, inter-rater agreement (kappa 0.66-0.81) and intrarater agreement (kappa 0.64-0.88) on the UERS was either good or excellent. The MHC and the UERS provide standardized, reliable, reproducible, and efficient instruments that can be used by occupational therapists and orthopedic surgeons to evaluate the upper extremities of children with CP.
