Further, evaluate reliability, validity sensitivity (ArmA-S) upper limb spasticity caused by injuries central nervous system (CNS). Materials methods was adapted according established guidelines. Validity reliability were evaluated 61 Face content expert opinions from clinicians feedback Internal consistency assessed Cronbach’s alpha test-retest using quadratic weighted kappa. Results ArmA-S shown be clinically feasible, good face no floor or ceiling effects. high equivalent ArmA; Chronbach´s coefficients values 0.94 0.93 section A B, respectively.
