Explain how diabetes can affect orthotic needs.

Diabetes significantly impacts orthotic needs primarily because it can lead to complications such as neuropathy and foot deformities. Neuropathy, a common complication of diabetes, results in nerve damage that can impair sensation in the feet. This loss of feeling makes individuals less aware of injuries or pressure points, which can lead to ulcers or infections.

In addition to neuropathy, diabetes can also contribute to various foot deformities, such as hammertoes, bunions, or Charcot foot, which alter the biomechanics of walking and can lead to increased strain on specific areas of the feet. As a result, individuals with diabetes often require custom orthotic devices designed to accommodate these deformities, redistribute pressure, and provide suitable support to enhance mobility and prevent injuries.

Considering the other options, the assertion that diabetes has no effect on orthotic needs is inaccurate given the significant complications associated with the condition. The idea that it reduces the necessity for orthotic devices fails to recognize the need for support and protection in diabetic patients. Finally, the notion that diabetes only affects upper body orthotics overlooks the substantial impact the disease has on the lower extremities, which are critical in determining orthotic requirements.
