(Lundin-Olsson, 1997: 58 institutionalized residents, (mean age [SD] 80·1 [6·1] years; 72% women).cognitive impairment and depression were not excluded. Subjects were able to walk with or without aids)
- Specificity = 95%, sensitivity = 48%. Positive predictive value = 83%; negative predictive value = 76%.
(Bloem, 2000: 14 iPD, 5 controls; Patients with cognitive impairment were excluded).
- Within PD group: SWWT poor sensitivity (14.3% and adequate specificity (91.7%) Poor predictor of falls in PD.
(Hyndman, 2004: Sixty three participants (36 men, 27 women; mean (SD) age 68.4 (10.6)) were recruited. Four subjects had a brainstem lesion, 30 had right hemisphere, and 29 left hemisphere infarctions. Mean time since onset of stroke was 20 months (range 2–72)).
- Within CVA group: For all fallers (> 1) the positive predictive value of SWWT was 62% (16/26), the negative predictive value 62% (23/37), specificity 70% (23/33) and sensitivity 53% (16/30). For repeat fallers (> 2) the positive predictive value of SWWT was 42% (11/26), the negative predictive value 89% (33/37), specificity 69% (33/48) and sensitivity 73% (11/15).
