BACKGROUND AND OBJECTIVECalcific tendinitis of the shoulder can cause pain in the shoulder and upper arm, with decreased function. administration of their usual dopaminergic medication (On).
METHODSExperimental sessions included a three-meter timed up and go test (TUG), modified to simulate a home environment. The trials were recorded by video, as well as by using wearable technologies, with position sensors placed on each shin, connected by Bluetooth. Algorithms were designed to detect and classify FOG episodes in all subjects.
RESULTSDuring the sessions, 25 of 28 patients with FOG demonstrated one episode during testing. The degree of gait abnormality was found to be greater among those with FOG than among those without. Compared to the clinical assessment, automatic FOG detection using wearable devices resulted in a sensitivity of 93.41%, a specificity of 98.51%, a positive predictive value of 89.55% and a negative predictive value of 97.31%.
CONCLUSIONThis study found that wearable technology can be used to automatically detect episodes of freezing of gait in patients with Parkinson′s disease.
