The weak foot is marked by lack of strength as compared with what would be the usual strength of the foot.

Weakness of the foot may be due to a variety of underlying conditions including: fracture; trauma; severed tendon; strain; sprain; nerve injury; flat foot; diseases, such as muscular dystrophy; or immobility of the foot following surgery.

Signs and symptoms may include: an abnormal gait; deterioration of the musculature; impaired circulation; bilateral foot weakness; limited movement of the foot; and difficulty in standing or walking.

Tests to determine the cause of weak feet may include: a complete history and physical examination; x-rays; bone scans; magnetic resonance imaging (MRI); computed tomography (CT) scan; and blood tests.

Treatment will depend upon the cause and severity of the weakness. Immobilization and supportive orthotic devices may constitute parts of the treatment.

Residuals will depend on the cause and the severity of the weakness. Impairment may range from limited impairment in mobility to complete immobility. Orthotic devices may be used indefinitely.

• The rating schedule for musculoskeletal was updated on February 7, 2021. Protection still does apply and should be considered with existing evaluations (38 CFR 3.951(a)).

• Rate the underlying condition 38 CFR 4.71a [Schedule of ratings-musculoskeletal system].

• When multiple foot disabilities are present, but the etiology of the symptoms cannot be separated, assign a single disability evaluation for the predominant symptoms. If the etiology of the symptoms can be delineated, separate disability evaluation may be assigned under multiple DCs for foot disabilities provided that the principles of 38 CFR 4.14 have not been violated.

• None.
