In this 14-item scale, patients must maintain positions and complete moving tasks of varying difficulty. In most items, patients must maintain a given position for a specified time. Patients receive a score from 0-4 on their ability to meet these balance dimensions. A global score can be calculated out of 56. A score of 0 represents an inability to complete the item, and a score of 56 represents the ability to independently complete the item.

A 9-item questionnaire with questions related to how fatigue interferes with certain activities and rates its severity according to a self-report scale. The items are scored on a 7 point scale with 1 = strongly disagree and 7= strongly agree. The minimum score = 9 and maximum score possible = 63. Higher the score = greater fatigue severity.

The score of the BI is a summed aggregate and there is preferential weighting on mobility and continence. The scores are allotted in the following way: 0 or 5 points per item for bathing and grooming; 0, 5, or 10 points per item for feeding, dressing, bowel control, bladder control, toilet use, and stairs; 0, 5, 10, or 15 points per item for transfers and mobility. The Index yields a total score out of 100 - the higher the score, the greater the degree of functional independence.

It is a self-report scale containing 49 items. Items are rated on a 5-point Likert scale. Higher scores indicate better functioning.

The PHQ-9 contains the 9 items. Each item is evaluated on a severity scale ranging from 0 to 3 where the respondent is asked to rate how often each symptom occurred over the last 2 weeks (0-not at all; 1-several days; 2-more than half of the days or 3-nearly every day), yielding a total score ranging from 0-27. Score interpretation:1-4 minimal depression; 5-9 mild depression; 10-14 moderate depression; 15-19 moderately severe depression; and 20-27 severe depression.
