Outcome Measures

Primary Outcomes (1)

  • 6-minute walk test (6MWT)

    The distance (meter) and walking speed (meter per seconds) in a 6-minute walk test.

    6 minutes

Secondary Outcomes (3)

  • Heart rate

    5 minutes

  • The Borg Rating of Perceived Exertion (RPE) scale.

    2 minutes

  • Myasthenia gravis composite score (MGC)

    30 minutes

Study Arms (1)

Myasthenia patients

Danish patients with myasthenia gravis seen at the Department of Neurology, Rigshospitalet

Other: 6-minute walk test

Interventions

The 6-minute walk test (6MWT) is widely used in the clinic to measure treatment efficacy and disease progression in patients with neuromuscular diseases and is found valid and reliable to measure decrease in walking speed for neuromuscular patients.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with MG seen in the Department of Neurology, Rigshospitalet, fulfilling the inclusion criteria.

You may qualify if:

  • Able to provide signed informed consent.
  • Able to read and understand Danish or English.
  • Diagnosis of mild to moderate MG (Able to provide signed informed consent.
  • Able to read and understand Danish or English.
  • Diagnosed with generalized mild to moderate myasthenia gravis (I-IV on the Myasthenia Gravis Foundation of American Clinical Classification, MGFA).
  • Documented history of acetylcholine receptor (AChR) or Muscle Specific Kinase (MuSK) antibody positive, or abnormal repetitive nerve stimulation testing (decrement \> 10%) on electromyography (EMG) or abnormal single fiber EMG (conduction block or jitter) or based on their clinical history and symptom improvement with acetylcholinesterase inhibitors.
  • Ability to walk \> 60 meters in a 6MWT.

You may not qualify if:

  • MGFA grade V disease
  • Other disorders that are not related to MG, or drugs, that interfere with muscle strength, walking ability, balance and fatigue (e.g. heart failure).
  • Serious medical illness (e.g. uncontrolled insulin dependent diabetes mellitus, symptomatic coronary artery disease, and cancer).
  • Dementia or pregnancy.
  • Unspecified reasons judged by the investigator
