15 Warning Signs Of Cerebellar Degeneration
10. Hypotonia

Hypotonia is characterized by abnormally low muscle tone—patients’ limbs feel “floppy” and offer little resistance when moved passively. This reflects the cerebellum’s role in modulating baseline muscle tension. Hypotonia can impair posture, making sitting unsupported difficult, and may contribute to joint laxity or scoliosis over time. Management includes physical and occupational therapy to strengthen antigravity muscles, use of orthotic devices for joint support, and teaching adaptive techniques to maintain functional mobility and prevent contractures.
