    Study Notes

    Exercise Testing & Functional Assessments

    • Heidi Tymkew PT, DPT, MHS is a board certified clinical specialist in cardiovascular and pulmonary physical therapy.
    • Functional assessments aid in determining exercise capacity.

    Monitoring

    • Vital signs are monitored before, during, and after exercise. These include heart rate (HR), blood pressure (BP), and oxygen saturation (SpO2).
    • Rate Pressure Product (RPP) is a measurement.
    • Rating of Perceived Exertion (RPE) is observed during exercise.
    • EKG (Electrocardiogram) is used to monitor cardiac activity during exercise.
    • Angina is a chest pain symptom that's monitored during assessments.
    • Observing the patient includes checking skin color, coordination, alertness/cognition, and signs of lightheadedness/dizziness.

    Normal Response to Exercise

    • Graph shows the typical response of healthy men to a treadmill test (Heart Rate, Systolic Blood Pressure, and Diastolic Blood Pressure). These change over time during exercise. This graph shows a normal response.
    • Data, age ranges, percentile, heart rate (bpm), systolic blood pressure (mmHg), diastolic blood pressure (mmHg) are all shown in graphical form.
    • Various graphs show data across age ranges and percentiles during the different phases of exercise.

    Abnormal Response to Exercise

    • Excessive or flat/decreasing heart rate
    • Hypertensive response (SBP > 210 mmHg and/or DBP > 110 mmHg).
    • Progressive decrease in systolic blood pressure (SBP) by 10-15 mmHg compared to baseline with activity.
    • Failure of systolic blood pressure (SBP) to increase with increased activity.
    • Significant changes in cardiac rhythm.

    Signs & Symptoms of Exercise Intolerance

    • Moderately severe or increasing angina
    • Marked dyspnea (difficult or labored breathing)
    • Dizziness, lightheadedness, or ataxia (lack of muscle coordination).
    • Cyanosis or pallor (bluish skin discoloration)
    • Excessive fatigue
    • Leg cramps or claudication (muscle pain and cramping)

    Heart Rate Recovery

    • Measures the heart's ability to return to a normal resting state after exercise.
    • Good heart rate recovery is 12-18 beats or higher.
    • Recovery of less than 12 beats is considered abnormal and increases the risk of coronary artery disease (CAD) and cardiovascular (CV) death.

    VO2 Max Exercise Test

    • Gold standard for measuring exercise capacity.
    • Requires specialized equipment (e.g., a metabolic cart).
    • Usually done in a laboratory setting.

    6 Minute Walk Test (6MWT)

    • Objective measurement of functional exercise capacity.
    • Standardized test using a 100-foot (30m) hallway.
    • Provides normal values in healthy adults (400-700 meters).

    6 Minute Walk Test (6MWT; Specific conditions)

    • Coronary Artery Disease (CAD): Minimum clinically important difference (MCID) during cardiac rehab is 25 meters.
    • Heart failure: The test is used to predict mortality and hospital readmission. A 6MWD under 300 meters is considered a poor prognosis; less than 200 meters suggests an increased risk of death.

    2 Minute Walk Test (2MWT)

    • Similar to 6MWT, useful for patients with low endurance.
    • Limited research in patients with circulatory-related impairments (CVP).
    • MID score for patients with Chronic Obstructive Pulmonary Disease (COPD) is 5.5 meters.

    2 Minute Walk Test (2MWT); Normative values

    • Provides normative data (distances in meters) for men and women across various age categories (18-85+).

    2 Minute Step Test (2 MST)

    • Measures endurance and exercise capacity.
    • The test involves stepping up and down a 6'', 12'', and 18'' step, for a set period of time and counting steps.
    • Data for the step test includes normative values (step counts) for various age groups (men/women). The data was established using Rikli & Jones in 1999, and by Wegrzynowska-Tedorzyk in 2016 for heart failure patients. A different set of data is also shown for higher blood pressure.

    Gait Speed

    • Often measured using a 4- or 5-meter walk test.
    • Provides functional tasks related to gait speed (e.g., self-care, household activities, climbing stairs).
    • Walking speed is measured in m/s, mph, and METS.
    • Tests are frequently used for heart failure patients to evaluate activity levels, and surgery patients to determine recovery.

    Gait Speed; Cardiac conditions

    • Heart failure: Gait speed less than 0.7 m/s indicates poor exercise capacity and a speed less than 0.80 m/s shows an increased risk of hospital readmission.
    • Cardiac surgery: Slow gait speed (less than 0.83 m/s) is associated with an increase in in-hospital mortality, surgical complications, and longer hospital stays.

    Seated Step Test

    • Developed for individuals unable to stand.
    • Measures aerobic capacity without reaching an upright posture.
    • Measures heart rate, blood pressure (BP), and oxygen saturation (SpO2) to monitor responses during varying elevation stages of the test.

    5 Times Sit to Stand Test (5 STST)

    • Measures lower extremity (LE) strength and power.
    • Scores the time it takes for an individual to stand up and sit down from a chair, 5 times.
    • Time is a key measurement in this test.
    • Arms should not be used.

    30 Second Chair Stand Test

    • Measures endurance and lower extremity (LE) strength.
    • The number of times an individual can stand from a chair in 30 seconds is recorded.
    • The test is for men and women, across various age groups.

    30 Second Chair Stand Test (additional info)

    • It is used to evaluate the independent ability to stand from a chair in 30 seconds as well as for determining cutoff scores to determine a patient's tolerance for exercise.

    Short Physical Performance Battery (SPPB)

    • A comprehensive test that helps determine physical impairment levels.
    • Assessments include balance, gait speed, and chair stands. It is tested across various conditions (heart conditions, etc.).
    • Used by healthcare professionals, in clinical settings to test various patient populations.

    Short Physical Performance Battery (SPPB); Heart Failure

    • Individuals with heart failure who have lower SPPB scores (5-7) tend to have more severe symptoms, a higher risk of adverse events (e.g., death or readmission), and are more prone to frailty (with a cutoff for this at below 6).
    • A minimum clinically important difference (MCID) of > 1 point observed in older cardiac rehab patients.

    Hypoactivity Syndrome

    • Principal movement impairment: inadequate activity or movement levels cause decreased endurance/exercise capacity.
    • Individuals unable to participate in activities for a prolonged time show symptoms of the condition.

    Specific tests for exercise monitoring (various)

    • There are details for various tests to monitor for exercise intolerance/capacity including tests for heart rate/blood pressure, respiratory function, and blood oxygen levels.
    • Various types of data are collected depending on the specific test.

    Lab Considerations for Exercise Testing

    • Instructions for completing a 6-minute walk test (6MWT).
    • Guidelines for monitoring vital signs during different portions of the testing procedures.
    • Methods for performing a seated step test and determining max heart rate during each portion of the test.
    • Directions for performing the Short Physical Performance Battery (SPPB) test.
