Description of intervention(s) / exposure
Location: pre-admission clinic and hospital corridor
Procedure: NB: these procedures are part of the study, not a usual component of routine preadmission standard assessment. The study procedures will occur during the routine PAC visit, which may occur at any time between one month and one day prior to surgery. The study procedures will be completed at a single session, anticipated to take no more than 30 minutes to complete all components.
1) questionnaire - International Physical Activity Questionnaire, Duke Activity Status Index, self-rating of ease of stair climbing
2) self-rating of ability to climb a flight of stairs. This will be done using a simple Likert scale. As there is no previous research on this particular question, there is no established tool for this. The researcher will then take the patient to a flight of stairs in the hospital and time how long it takes to ascend.
3) A near-infra-red spectroscopy monitor will be placed on the calf prior to activity to measure muscle oxygen saturation
Timing: once

Outcomes
Primary outcome [1] 324999 0
Association between self-rated ability to climb stairs and objective measurement of ability to climb stairs by calculation of work using mass moved x time taken x distance covered.
Self-rated ability will use a 5 point Likert scale.
Patient mass will be taken from the weight recorded as part of the routine PAC nursing assessment.
Time will be measured with a stop watch.
Distance: the height of the stairs and therefore the distance covered will be pre-measured.
Timepoint [1] 324999 0
At time of stair climb performance
Secondary outcome [1] 386512 0
Association between subjective measure (self-rated ability) of stair climb ability with physiological measurement of lower limb muscle oxygen saturation using near infra-red spectroscopy.
Timepoint [1] 386512 0
At the time of stair climb performance
Secondary outcome [2] 387393 0
Association between objective measure (power calculation) of stair climb ability with physiological measurement of lower limb muscle oxygen saturation using near infra-red spectroscopy.
Objective calculation of power will be performed using the following equation: Power = mass x time x vertical distance
Timepoint [2] 387393 0
At time of stair climb

Eligibility
Key inclusion criteria

- All patients at preadmission clinic (PAC) as a convenience sample
- We will aim for a range of ages and weights and operation severity
- Patients who use a walking aid will be included if they are willing to perform as they usually would when asked to climb a FOS
Minimum age
18 Years
Maximum age
90 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- age < 18yr,
- a measure of adiposity beyond which the NIRS is likely to be unreliable (currently thought to be a BMI > 60 kg/m2),
- if a patient answers “impossible” to ease of climbing a flight of stairs then the study will not continue

Statistical methods / analysis
- Sample size – initial feasibility testing sample of 100 patients
- Will be numerical, ordinal, and nominal ranges for both the baseline data and for the objective data
- NIRS data will be interpreted from an excel spreadsheet, with averaging of saturation levels over the various periods

Summary
Brief summary
This project aims to identify whether patient self reported ability to climb a flight of stairs (FOS) correlates with objective measures, and whether self-reported or objective measures correlate with near infra-red spectroscopy (NIRS) measures of leg muscle oxygen saturation. Patients from an anaesthetic pre-admission clinic will be asked to self report their ability to climb a FOS before having a NIRS device (non invasive way to measure muscle oxygen saturation) attached to their leg, and then climbing a flight of stairs. Additional parameters will be measured including Borg scale, heart rate and duration of exercise.
