  • 5F: Impaired Peripheral Nerve Integrity and Muscle Performance Associated with Peripheral Nerve Injury


A 42-year-old female presents with a severe pain in the ball of her right foot that radiates into her second and third toes. She states the pain started about 1 week ago. She describes the pain as being sharp and burning in nature. She does not recall a specific injury but does state that she started barefoot running 6 weeks ago and eliminated her heel strike. She also goes to dance classes for the past 4 weeks. She feels better with a hard soled shoe on but cannot wear her dress shoes, especially heels. Upon palpation there is a thickening of the tissue between toes 2 and 3 right. Tenderness is present in the same region. There is hypomobility of the MTP toes 2 and 3 right and a positive pinch test. The patient’s radiograph, which was ordered by the referring physician, is negative for any fractures.



  • Painful condition that affects the ball of the foot

  • Growth of scar tissue from chronic irritation of compression

  • Most common area is between the third and fourth toes, but also can be in between the second and third toes

  • Involves a thickening of the tissues (neuroma) around one of the intermetatarsal plantar nerves

  • Branches from the medial and lateral plantar nerves

  • May alter mechanics during the push-off phase of gait

Essentials of Diagnosis

  • Can be an independent diagnosis and not associated with a disease process

  • Characterized by numbness, burning, and pain

  • Sometimes relieved by removing shoes

  • No visible deformity

  • Higher risk for individuals with bunions and flat feet

General Considerations

  • Feeling like you are stepping on something like a pebble

  • A burning pain in the ball of the foot that radiates to the toes

  • Tingling or numbness in the toes

  • Titled a neuroma, but is not a tumor formation as “oma”


  • Ladies wearing high heels

  • Rock climbers with repetitive forefoot pressure



  • Burning pain in the ball of the foot

  • Numbness and tingling in the toes, especially between the ...
