Feasibility and Effectiveness of tDCS in the Treatment of Post-stroke Fatigue (EFECTS).

The scale consists of 10 questions about the characteristics of fatigue in the current daily routine, which are rated on a five-point range from 1, "never," to 5, "always." Higher scores indicate more fatigue, with a cut-off point of ≥24 defining the presence of fatigue.

It is a scale that can be used both at the hospital and outpatient level. It consists of 14 questions: 7 questions related to depression and another 7 related to anxiety. An independent score on each scale of ≥ 8 will be suggestive of depression and/or anxiety.

It is a scale with 15 items that is used to measure the severity of stroke. It includes different areas: level of consciousness, eye movements, integrity of visual fields, facial movements, muscle strength, sensitivity, coordination, language and negligence. Each item is scored on an ordinal scale from 0 to 2, 0 to 3 or 0 to 4. The total is added and a score is obtained that can range from 0 to 42, the higher the score, the greater the deficits.

The Borg scale is a tool that measures a person's perception of exertion, shortness of breath, and fatigue during physical exertion. It is a modified scale, it is an 11-point scale that ranges from 0=no fatigue to 10=very great effort.

This is a Likert-type scale that evaluates the quality of sleep during the last week. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance.

It is the most commonly used functional measure in stroke research, particularly in studies evaluating the effectiveness of treatments. The scale is numerical and ranges from 0 to 6. 0: no symptoms; 1: without significant disability (the patient is able to carry out his/her usual activities and obligations); 2: mild disability; 3: moderate disability; 4: moderately severe disability; 5: severe disability (totally dependent patient); 6: death.

To measure the level of physical activity during the last week. There are two forms of output from scoring the IPAQ. Results can be reported in categories (low activity levels, moderate activity levels or high activity levels) or as a continuous variable (MET minutes a week). MET minutes represent the amount of energy expended carrying out physical activity. A MET is a multiple of your estimated resting energy expenditure. One MET is what you expend when you are at rest. Therefore 2 METS is twice what you expend at rest. To get a continuous variable score from the IPAQ (MET minutes a week) we will consider walking to be 3.3 METS, moderate physical activity to be 4 METS and vigorous physical activity to be 8 METS.

Assess the quality of life perceived by the patients. The scale ranges from 100 ('the best imaginable health state' or 'the best health state you can imagine') to 0 ('the worst imaginable health state' or 'the worst health you can imagine'). This is used to obtain a respondent's stated preference values, not to record their own health state.
