Personalized strength training for adults with hypokalemic or hyperkalemic periodic paralysis

Effect of Physical Training in Individuals With Hypokalemic and Hyperkalemic Periodic Paralysis

NA · Rigshospitalet, Denmark · NCT07194174

This study will try a 12-week personalized, supervised strength-training program for adults with genetically confirmed hypokalemic or hyperkalemic periodic paralysis to see if muscle strength and structure improve.

What this trial studies

This is a 24-week prospective study with clinical testing and questionnaires at baseline, 12 weeks, and 24 weeks. Between weeks 12 and 24 participants follow a personalized strength-exercise program supervised by study investigators. The protocol includes assessments of muscle structure and function, along with patient-reported outcomes. Eligible participants are adults with genetically confirmed HypoPP or HyperPP who can ambulate independently and stand from a chair without using their hands.

Who should consider this trial

Good fit: Adults (≥18 years) with genetically confirmed hypokalemic or hyperkalemic periodic paralysis who can walk at least 10 meters independently and can rise from a chair without using their hands.

Not a fit: Patients with other significant causes of muscle weakness, unstable heart or lung disease that make exercise unsafe, or those unable to complete supervised training are unlikely to benefit.

Why it matters

Potential benefit: If successful, the program could increase muscle strength and functional mobility and potentially reduce the frequency or severity of paralysis episodes.

How similar studies have performed: Small case series and exercise programs for neuromuscular channelopathies suggest safety and possible benefit, but there is limited high-quality evidence specifically in periodic paralysis.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients with genetic verified HypoPP or HyperPP
* Age minimum 18 years
* Able to walk a minimum of 10 meters independently with or without assistive devices and be able to stand from a chair without using hands

Exclusion Criteria:

* Other significant cause of muscle weakness
* Heart or lung disease which, in the investigator's opinion, makes participation in the study training inadvisable

Exclusion from muscle biopsy

* Anticoagulant treatment
* Impaired blood clotting due to disease

Exclusion from MRI scanning due to:

* Metal implants in the body that contraindicate MRI scanning or are positioned such that the scan quality is significantly affected
* Claustrophobia
* Pregnancy
