Background
The skeletal muscle channelopathies are a diverse group of diseases caused by mutations in muscle ion channels. They can be divided into the non-dystrophic myotonias and periodic paralyses (PP).
Study information
This is a retrospective study comparing patients with genetically diagnosed PP to healthy volunteers.
Primary objective
To define the presence, frequency and pattern of MRI abnormalities in the legs of PP patients.
Secondary objective
To describe differences in MRI abnormalities in a subset of PP patients.
Recruitment
Approximately 40 patients with genetically confirmed PP.
For blinded analysis, 12 healthy volunteers will undergo standard lower limb MRI. In addition the MRI scans from 12 healthy volunteers from a previous research study will be used.
