Muscle Weakness

What is Muscle Weakness?

Chronic muscle weakness means muscles that tire rapidly, feel heavy or unreliable, or struggle to perform tasks that should be well within their physical capacity. It is distinct from muscle aches — the muscles are not necessarily painful, they just do not have the strength or endurance expected. In nervous-system-driven conditions, weakness often co-exists with fatigue and post-exertional worsening.

How to know if Muscle Weakness is chronic

• Persisting for more than 4 weeks without improvement
• Not explained by lack of exercise or recent injury
• Accompanied by fatigue or post-exertional crashes
• Affecting multiple muscle groups

Muscle Weakness can be associated with the following conditions:

• • Post-Viral Fatigue Syndrome
  • Chronic Fatigue Syndrome
  • Post-Exertional Malaise (PEM)
  • POTS: Postural Orthostatic Tachycardia Syndrome
  • Fibromyalgia

How brain training & re-origin can help

Muscle weakness in the context of CFS and post-viral conditions reflects a nervous system and energy system that are both impaired. Re-origin’s careful, paced approach to brain retraining supports nervous system regulation without pushing the body beyond its current capacity — allowing muscle function to improve gradually as the system as a whole recovers.
