Patient demographics. (A) Stroke survivors of wide-ranging ages participated in the study. (B) All participants had good cognitive ability as shown by a relatively high information processing speed (IPS), an average of 1 s per symbol in the Symbol Digit Modalities Test (Coding – Copy) and Sustained Attention Index (SAI). Zero indicates very high attention score and positive scores show progressively poorer attention. Self-reported fatigue was quantified using two questionnaires, FSS (C) and Neurological Fatigue Index – Stroke specific scale (NFI-Stroke, D). The fatigue levels in the current study population included those with both high and low levels of fatigue. (E) FSS and NFI-stroke were significantly correlated.
