Question

If a patient held on to support rail during the test, what potential impact might this have had on measured exercise test duration and estimated MET and why?

Answer 1

Measured exercise test duration can help in eliciting the bodys reaction to increase in acute exercise.

There are changes in heart rate, blood pressure, respiration, and this data helps in analyzing the cardiovascular condition and function.

Excercise is also known to elicit cardiovascular changes that makes not be detected at rest. Other may also help ananlyze the cardiovascular and left ventricular response to excercise.

Activities of daily living and excercise importance are basically given based on maximal oxygen uptake.

It is forund that the total trendmill time is known to be longer when hand mill support is permitted.

It is also known that handrail support is known to contribute Independently to an overestimated value.

There have been several formulae to predict maximum oxygen uptake when tue standard Bruce protocol is used with or without handrail.

The aim of the above study was to assess if handrail support which is limited to distal phalanx of the left index and middle figure would help reduce the difference in the total treadmill time and may help eliminate the disparity in the pxygen kinetic response that may occur during the test with limited and without handrail support using the modified Bruce protocol.

The study concluded that diagnosis and the estimation of functional and maximum aerobic capacity are affected when the duration of excercise is increased by hand rail support.

The study also helped demonstrate that Trandmill excercise time can be reduced and controlled when the hand rail support is limited to tips of two finger of one hand.

Therefore it is necessary to reduce hand rail support duration and it should be standardized.
