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.

Interventions

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 Researcher: university students

Eligibility

Sex/Gender

All

Age

18 Years to 90 Years

Healthy volunteers

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

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
