Quadriceps muscle weakness increases the risk of incident knee pain [ 56] and is associated with increased pain and reduced function in individuals with knee osteoarthritis [ 57].
Most of the patients with HD do not report respiratory symptoms until later stages of the disease when the impaired motor control of swallowing muscles and respiratory muscle weakness increase the risk of pneumonia by aspiration, causing death in the majority of patients with HD [ 3, 7- 9].
This may be attributed to muscle wasting and weakness, increased muscular fatigability, impaired psychosocial and functional capacity that has been associated with HIV infection [ 7].
The muscle weakness and increased risk of irregular heart beat in TPP result from markedly reduced levels of potassium in the bloodstream.
Disruption of the DAG complex occurs in dystrophinopathies and sarcoglycanopathies, two genetically distinct classes of muscular dystrophy characterized by progressive loss of muscle mass, muscle weakness and increased fatigability.
-, - They also dismissed the evidence that vitamin D deficiency causes muscle weakness and increased risk for falling.
While the adaptive changes in diaphragm muscle are complex, ultimately EMP augments the energetic requirements of respiratory muscles which, concomitant with EMP-induced reductions in muscle mass, contributes to diaphragm weakness, increased fatigability and overall dysfunction.
Buckling of a limb, which may occur due to pain or muscle weakness, greatly increases the risk of falling.
