title: Evaluation scale development, reliability for sitting and standing from the chair for Duchenne muscular dystrophy.
abstract: The authors aimed to (a) develop a scale to evaluate non-wheelchair-dependent children with Duchenne muscular dystrophy (DMD) while sitting and standing from the chair, (b) test its reliability, and (c) correlate the scores of this scale with the time, the age and the Vignos. Thirty DMD boys performed sit-to-stand and stand-to-sit from the chair 4 times. Scale development was based on a previous movement characterization in healthy children and in DMD children and on suggestions by physical therapists with expertise in DMD. The final version of the scale was submitted to the analysis of reliability. The sitting evaluation consists of phases: flexion, contact of the hip with the chair, extension. The standing evaluation comprehends the phases: flexion; transference; extension. Sitting and standing phases presented an excellent reliability (intraclass correlation coefficient [ICC] ≥ 0.91) and a good reproducibility (ICC ≥ 0.89). The scores generated by sitting on the chair correlated to the time taken to perform the tasks (r = .69) and to the age of the patient (r = .44) and the score of standing from the chair also correlated to the time of performance (r = .66). The sit-to-stand functional evaluation scale DMD is a reliable assessment tool that allows the description and quantification of the functional performance of DMD children.
