NCT01306994

Brief Summary

The hypotheses of the present study of Freeman-Sheldon syndrome (FSS) and related conditions are: (1) that exercise capacity is lower in FSS patients versus normal controls, and the lower exercise capacity is due to changes in the muscles' normal structure and an inability of sufficient quantity of the energy molecule to bind to muscle; (2) this muscle problem reduces amount of air that can get in the lung and amount of oxygen carried in the blood, which then has the effect of increasing heart and respiration rates, blood pressure, and deep body temperature, and produces muscle rigidity; (3) the events noted above, when they occur during cardiac stress testing, are related to a problem similar to malignant hyperthermia (MH) reported in some muscle disorders without use of drugs known to cause MH. MH (a life-threatening metabolic reaction that classically is triggered when susceptible persons receive certain drugs used in anaesthesia.

Outcome Measures

Primary Outcomes (2)

  • Heart rate

    Increased heart rate, measured electrocardiographically, is used as an index of cardiovascular strain imposed by needs during exercise and exaggerated by Freeman-Sheldon and related conditions.

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

  • Oxygen Consumption

    Oxygen consumption, measured by ventilation of expired oxygen, is used as a measure of physiological strain imposed by metabolic needs during exercise and exaggerated by Freeman-Sheldon and related conditions.

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

Secondary Outcomes (12)

  • Non-Invasive Arterial Blood Pressure

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

  • Spirometry (Forced Expiratory Volume/Forced Vital Capacity)

    Evaluated before and after exercise, during two study visits (lasting an average of 1-3 hours)

  • Saturation of Peripheral Oxygen

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

  • Respiratory Rate

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

  • Heart Rhythm

    Evaluated at rest and while exercising, during two study visits (lasting an average of 1-3 hours)

  • +7 more secondary outcomes

Other Outcomes (2)

  • Body Composition

    Evaluated before exercise, during two study visits (lasting an average of 1-3 hours)

  • Hand Grip Strength

    Evaluated during the first of two study visits

Interventions

Completed during the clinical examination and exercise test by the researchers, lactate, glucose, and free and total adenosine triphosphate blood levels are determined at rest and during exercise.

Control GroupSyndrome Group

During exercise, heart and lung function are monitored for changes caused by exercise, which increases the body's need for oxygen and puts extra demands on the heart. In this study, testing is done using a cycle ergometer and conducted according to the standardised exponential exercise protocol (STEEP).

Also known as: stress test, graded exercise test, maximal exercise test, VO2 max test, maximal oxygen uptake test, exercise tolerance test, exercise stress test
