The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').

Ask the patient to rate their current level of pain by placing a mark on the line. Use a ruler to measure the distance in centimetres from the 'no pain marker' (or zero) to the current pain mark. This provides a pain intensity score out of 10; for example, 6 out of 10 (or 6/10).

The FSS questionnaire contains nine statements that rate the severity of fatigue symptoms. A low value (e.g., 1) indicates strong disagreement with the statement, whereas a high value (e.g., 7) indicates strong agreement. A total score of less than 36 suggests that the patient may not be suffering from fatigue.

A total score of 36 or more suggests that the patient may need further evaluation by a physician.

The Functional Ambulation Categories (FAC) is a functional walking test that evaluates ambulation ability. This 6-point scale assesses ambulation status by determining how much human support the patient requires when walking, regardless of whether or not they use a personal assistive device. A score of 0 indicates that the patient is a non-functional ambulator (cannot walk).

A score of 1, 2 or 3 denotes a dependent ambulator who requires assistance from another person in the form of continuous manual contact (1), continuous or intermittent manual contact (2), or verbal supervision/guarding (3).

A score of 4 or 5 describes an independent ambulator who can walk freely on: level surfaces only (4) or any surface (5=maximum score).

The SF-12 is a self-reported outcome measure assessing the impact of health on an individual's everyday life. The SF-12 uses eight domains:

Limitations in physical activities because of health problems. Limitations in social activities because of physical or emotional problems Limitations in usual role activities because of physical health problems Bodily pain General mental health (psychological distress and well-being) Limitations in usual role activities because of emotional problems Vitality (energy and fatigue) General health perceptions

The Symbol Digit Modalities Test (SDMT) is widely used for cognitive evaluation of information processing speed, required in many cognitive operations. The person taking the test is provided with a set of symbols, each corresponding to a number. He or she is required to write down the symbols corresponding to a series of numbers within a short space of time. The SDMT is quick (~5 min) and straightforward to administer, provides a clear test score that is not influenced by subjective interpretations on the part of the healthcare professional who administers the test, and is little affected by patients׳ age, gender or educational status.

The Modified Barthel Index is an ordinal scale which measures a person's ability to complete activities of daily living.

The evaluated domains are:

• Feeding
• Bathing
• Grooming
• Dressing
• Bowel
• Bladder
• Toilet use
• Transfers bed-to-chair-and-back
• Mobility on level surfaces
• Stair negotiation The higher the score, the more independent the patient is in completing the measured activity. Higher scores also indicate the patient is more likely to return home, with varying degrees of assistance, following hospital discharge.

The lower the score, the more dependent the patient is with the activity completion, and the more skilled care will be required at discharge.

Serum prealbumin levels are measured using a blood test that can help assess nutritional status. Prealbumin is a protein made in the liver that helps transport thyroid hormones and vitamin A, and controls how the body uses energy. A prealbumin level below 30 mg/dL may indicate malnutrition.

A serum albumin test measures the amount of albumin in blood. Albumine dosage helps determining the presence of liver disease, kidney disease, or protein malabsorption. The normal range is 3.4 to 5.4 g/dL (34 to 54 g/L)

Body mass index (BMI) is a calculation that compares a person's weight to their height. It's a screening tool that can help determine if someone is a healthy weight for their height. BMI is calculated by dividing weight in kilograms by height in meters squared.

BMI categories:

Underweight: BMI is below 18.5 Healthy weight: BMI is between 18.5 and 24.9 Overweight: BMI is between 25 and 29.9 Obese: BMI is between 30 and 39.9 Severely obese: BMI is 40 or higher

Subjects sit in a standard chair. They are timed as putting on one sock

distance between the two middle fingers, one arm from above and one from below behind the back

distance between middle fingers and ground

subjects must stand on a single leg with eyes closed for the longest time possible while timed (max 30 seconds per limb).
