Ever wonder why individuals with Calpainopathy/LGMD2A exhibit a "waddling" gait when walking?
With the progression of LGMD2A the hip-girdle muscle weakness tends to be most prominent in the gluteus maximus and hip adductors muscles...this along with abdominal weakness, leads to a wide-based, lordotic gait or 'waddling' appearance when the individual ambulates.
The muscle weakness also causes a lordosis to develop. Lordosis refers to the inward curve of the lumbar spine (just above the buttocks). A small degree of lordosis is normal. Too much lordotic curving is often called a swayback (lordosis).
Lordosis tends to make the buttocks appear more prominent. Individuals with significant lordosis will have a large space underneath their lower back when lying face up on a hard surface.
The lordosis will increase as the muscle weakness progresses. In some ways, the arching of the back helps an individual compensate for the muscle weakness while attempting to maintain their center of gravity for balance.
