If you have instability issues when walking, there are a variety of root causes that might be producing your difficulties. Abnormal gait, the pattern of how you walk, can happen as a result of genetics, disease, trauma, or infection. Specific diseases that lead to instable walking include osteoarthritis, Parkinson’s, Alzheimer’s, MS, and Lyme diseases.
A major concern with an unstable gait is ensuring that you do not end up on the ground. Fall prevention measures will depend on your particular situation and may entail physical therapy, leg braces, orthotics, or use of a walker or cane.
