In contrast to sensory and autonomic disturbances motor function has seldomly been studied in diabetic neuropathy. Recently quantitative studies of long‐term type 1 diabetic patients have shown that the strength of the ankle and knee extensors and flexors are moderately impaired. The weakness is closely related to the severity of neuropathy. Applying quantitative electromyography the degree of reinnervation is related to the muscle strength in diabetic patients suggesting the reinnervation to be insufficient. Magnetic resonance imaging of the distal part of the leg has revealed substantial muscular atrophy closely related to the degree of muscle weakness. The present findings indicate that diabetic neuropathy often is a mixed sensory‐motor neuropathy.
