Abstract

Purpose: The purpose of this study was to examine the inter-rater reliability of two tests measuring selective motor control (SMC) of the lower extremities in children with cerebral palsy (CP).

Methods: Two testers independently assessed 21 children (13 boys, eight girls; mean age 6 years 5 months, SD 12 months) with spastic CP (14 unilateral and seven bilateral) using the Boyd and Graham SMC test (with an existing protocol) and the modified Trost SMC test (with a newly developed protocol). Inter-rater reliability was analysed using Cohen's Kappa.

Results: For the Boyd and Graham SMC test for ankle dorsiflexion, Kappa was 0.55 (95% CI = 0.36–0.74). For the modified Trost SMC test for ankle dorsiflexion, knee extension, hip abduction and hip flexion, Kappas were 0.65 (0.47–0.84), 0.69 (0.49–0.88), 0.57 (0.37–0.78) and 0.71 (0.51–0.91), respectively.

Conclusion: The SMC tests showed moderate (Boyd and Graham SMC test) to good (modified Trost SMC test) inter-rater reliability.

Resumen

Propósito: El propósito de este estudio fue examinar la confiabilidad inter-evaluador de dos pruebas de medición del control motor selectivo (SMC) de las extremidades inferiores en niños con parálisis cerebral (CP).

Métodos: Dos evaluadores valoraron de manera independiente 21 niños (13 niños, ocho niñas, edad media 6 ños 5 meses, SD 12 meses) con CP espástica (14 unilateral, 7 bilateral) utilizando la prueba de SMC Boyd y Graham (con un protocolo existente) y la prueba SMC de Trost modificada (con un protocolo recientemente desarrollado). La confiabilidad inter-evaluador se analizó utilizando la Kappa de Cohen.

Resultados: Para la prueba SMC Boyd y Graham para lo dorsiflexión del tobillo, la Kappa fue 0.55 (95% CI = 0.36 − 0.74). Para la prueba SMC de Trost modificada para la dorsiflexión del tobillo, extensión de rodilla, abducción de cadera y flexión de cadera, la Kappa fue 0.65 (0.47–0.84), 0.69 (0.49–0.88), 0.57 (0.37–0.78) y 0.71 (0.51–0.91), respectivamente.

Conclusión: Las pruebas SMC demostraron confiabilidad inter-evaluador moderada (prueba SMC de Boyd y Graham) a buena (prueba SMC de Trost modificada).
