Q

• Activity and muscle tone

What are the effects of Immobility?

A

Activity and muscle tone- Immobility decreases bladder and sphincter tone resulting in poor urinary control and urinary stasis. Indwelling catheters cause a decrease in bladder muscle tone because the bladder muscle is not being stretched other causes include child bearing, menopause(muscle atrophy), and muscle damage from trauma.
