Table 2 Diagnostic accuracy of gait disorder and intrinsic-extrinsic classification for detecting non-cardiovascular mediated falls (n = 41)

From: Gait disorders are associated with non-cardiovascular falls in elderly people: a preliminary study

Diagnostic Approach Patients with Non-CV Causes* Patients with CV Causes† Sensitivity (%) Specificity (%) p-value Fisher exact test
Gait Disorder + 34 1 97.1 83 <0.001‡
Gait Disorder - 1 5    
Extrinsic Fall 10 1 28 83 0.9128‡
Intrinsic Fall 25 5    
  1. *Non-CV cause: non-cardiovascular neurally mediated cause. †CV causes: cardiovascular neurally mediated cause. Gait Disorder +: presence of gait disorder. Gait Disorder -: absence of gait disorder. ‡p-value of the associations with non-cardiovascular mediated falls for each diagnostic approach.
  2. Note: Neurally mediated cardiovascular causes are the following: orthostatic hypotension, postprandial hypotension, vasovagal syncope and carotid sinus hypersensitivity.
