Which item is NOT a MSK or neuromuscular change related to existing muscle imbalances?

• A. Change in bowel and bladder
• B. Loss of sensation
• C. Loss of strength
• D. Pain at the site of the sac repair

Answer: (A)

The main idea here is how muscle imbalances in spina bifida/myelomeningocele affect the body. When the lower limbs develop imbalances, the musculoskeletal system and the neuromuscular control of those muscles show changes such as weaker strength in affected muscles and altered sensation due to nerve involvement. Bowel and bladder function, however, is controlled by autonomic and sacral spinal pathways. If those pathways are disrupted, you get neurogenic bowel or bladder, which is a neural/autonomic problem rather than a direct musculoskeletal or neuromuscular change from muscle imbalance. So, changes in bowel and bladder are not part of the MSK/neuromuscular adaptations caused by existing muscle imbalances. The other options—loss of sensation and loss of strength—reflect direct neuromuscular consequences of the spinal involvement, and pain at the sac repair site can relate to musculoskeletal tissue and compensatory mechanisms around the repair area.
