Arm non-use, defined as the difference between what the individual can do when constrained to use the paretic arm and what the individual does do when given a free choice to use either arm, has not yet been quantified in individuals post-stroke. 1) to quantify non-use post-stroke and 2) to develop and test a novel, simple, objective, reliable, and valid instrument, the Bilateral Arm Reaching Test (BART), to quantify arm use and non-use post-stroke. First, we quantify non-use with the Quality of Movement (QOM) subscale of the Actual Amount of Use Test (AAUT) by subtracting the AAUT QOM score in the spontaneous use condition from the AAUT QOM score in a subsequent constrained use condition. Second, we quantify arm use and non-use with BART by comparing reaching performance to visual targets projected over a 2D horizontal hemi-workspace in a spontaneous-use condition (in which participants are free to use either arm at each trial) to reaching performance in a constrained-use condition. All participants (N = 24) with chronic stroke and with mild to moderate impairment exhibited non-use with the AAUT QOM. Non-use with BART had excellent test-retest reliability and good external validity. BART is the first instrument that can be used repeatedly and practically in the clinic to quantify the effects of neuro-rehabilitation on arm use and non-use, and in the laboratory for advancing theoretical knowledge about the recovery of arm use and the development of non-use and ‘learned non-use’ after stroke.
