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.

The authors developed an evaluation scale for sit-stand from the ground for children with Duchenne muscular dystrophy (DMD) and tested its reliability. The construction occurred in stages: (a) the characterization of the movement in healthy children, (b) the characterization of the movement in children with DMD, (c) the elaboration of the 1st version of the scale and the manual, (d) the evaluation by experts and readjustments, and (e) the analysis of inter- and intraexaminer reliability and correlation with the Vignos Scale, age, and time for the execution of the activity. The scale comprehended 3 phases for sitting and 5 for the standing. A very good repeatability of the measures of sitting and standing (ICC = 0.89 and 0.84, respectively) and excellent reproducibility (ICC = 0.93 and 0.92, respectively) was demonstrated. The Kappa coefficient for the 8 phases in the interexaminer analysis varied from 0.77 to 1.00 (excellent reliability), and in the intraexaminer analysis varied from 0.80 to 1.00 (excellent reliability). Good correlation was found between the variables on the Vignos Scale (age: r = 0.58; stand: r = 0.56). The scale is a reliability instrument that allows evaluation of the activity of sitting and standing in children with DMD.
