Cаse Study 2: Amputаtiоn with Belоw-Knee Prоsthetic (M.L.) Scenаrio: M.L., a 45-year-old diabetic patient, underwent a below-knee amputation due to severe peripheral vascular disease complications. She uses a below-knee prosthetic to restore mobility and independence, relying on a custom socket and pylon system for weight-bearing and ambulation. Recently, her endocrinologist suspects a pituitary tumor due to hormonal imbalances from poorly controlled diabetes, which could impact her prosthetic rehabilitation by affecting her vision. 2.11  How can afferent autonomic information cause referred pain? Diabetes can lead to autonomic dysfunction and neuropathy, both of which may exacerbate referred pain. Referred pain mechanisms may contribute to phantom limb pain and abnormal pain perception in the residual limb. Pituitary tumor-induced hormonal changes may alter pain sensitivity and autonomic function, influencing rehabilitation outcomes. Multidisciplinary management (prosthetist, neurologist, endocrinologist, pain specialist) is essential for optimizing functional outcomes.

Cаse Study 3: Cоngenitаl Cоnditiоn with Scoliosis Brаcing (T.R.) Scenario: T.R., a 12-year-old child, was born with scoliosis, a congenital spinal curvature progressing during growth. He wears a custom scoliosis brace (e.g., Boston brace) to halt curve progression and maintain spinal alignment. The brace applies corrective pressure to the spine, reducing deformity and supporting posture until skeletal maturity. 3.5 Which is responsible for maintaining the resting membrane potential? Resting membrane potential influences muscle excitability and tone. In neuromuscular scoliosis (e.g., cerebral palsy, muscular dystrophy, or spinal cord injury), abnormal resting membrane potential may lead to: Spasticity (hyperactive muscle contraction) if neurons are overly excitable. Hypotonia (muscle weakness) if neurons are less excitable. Imbalanced muscle tone on either side of the spine can contribute to scoliosis progression. If resting membrane potential is disrupted, postural muscles may not contract properly, leading to asymmetrical spinal loading.
