#muscular weakness

• Adynamia — A state of extreme muscular weakness, profound physical exhaustion, and a severe decrease or complete loss of the body's motor strength; this structural and functional condition is encountered as a major symptom in grave infectious diseases, endocrine disorders (such as Addison's disease), shock states, or advanced malnutrition. It differs from ordinary fatigue by the actual physical inability to perform even elementary movements.
• Amyosthenia — A functional structural deficiency characterized by pronounced muscle weakness or lack of strength within the skeletal muscles. This pathological condition can be caused by muscle atrophy, metabolic disorders, malnutrition, or prolonged periods of physical immobilization.
