b. anticipate the need for weekly plasmapheresis treatments.
c. do frequent weight-bearing exercise to prevent muscle atrophy.
d. protect the extremities from injury due to poor sensory perception.

Muscles are generally strongest in the morning, and activities involving muscle activity should be scheduled then.

There is no decrease in sensation with MG, and muscle atrophy does not occur because although there is muscle weakness, they are still used.
