Metatarsophalangeal Joint Flexion Range Test Guide

1. Ankle & Foot (3)

2. Flexion: Metatarsophalangeal Joint

3.  Range of motion Great Toe : 0° – 45 ° Lateral Four Toes : 0° – 40 ° Testing position Supine or sitting, ankle & foot in 0° of dorsiflexion, plantar flexion, inversion, eversion. MTP in 0° abduction & adduction. IP 0° of flexion & extension Stabilization Stabilize metatarsal to prevent plantar flexion of ankle & inversion or eversion of foot. Do not hold MTP of other toes in extension, because tension in transverse metatarsal ligament will restrict the motion

4.  Goniometer Alignment Fulcrum Dorsal aspect of MTP joint Proximal Arm Dorsal midline of metatarsal Distal Arm Dorsal midline of proximal phalanx

5.  Alternative Goniometer Alignment For First Metatarsophalangeal Joint Fulcrum Medial aspect of the first MTP joint Proximal Arm Medial midline of the first metatarsal Distal Arm Medial midline of the proximal phalanx the first toe

6.  Patient Instruction Ask the patient to Bend their toe.

7.  Normal End Feel Firm, because of tension in: • Dorsal Joint capsule • Collateral ligaments • Extensor digitorum brevis

8. Hallux & Toe Metatarsophalangeal Flexion Muscles Lumbricales Flexor Hallucis Brevis

9. Lumbricales Origin: Tendons of Flexor digitorum longus + 1st lumbricale + 2nd-4th lumbricales Insertion: Toes 2-5 (proximal phalanges & dorsal expansions of tendons of Extensor digitorum longus) Innervation: Medial Planter Nerve (L5-S1)  1st lumbricale Lateral Planter Nerve (S2-S3)  2nd 3rd 4th lumbricales

10. Flexor Hallucis Brevis Origin: Lateral head: cuboid bone + lateral cuneiform bone Medial head: medial intermascular septum + tendon of Tibialis posterior Insertion: Lateral & Medial heads : Hallux ( proximal phalanx on both sides of base) + blend with abductor hallucis Intervention: Medial Planter Nerve (S1-S2)

11.  Patient Position The patient is short sitting with legs hanging over the edge of the table. The ankle is in a neutral position 1- Hallux MP Flexion (Flexor Hallucis Brevis) Test For Grades 5, 4, 3, 2, 1 and 0  Therapist and Patient Instructions   The therapist is seated on a stool in front of the patient. The test foot rests on the examiner's lap. The therapist stabilizes the dorsum of the foot just below the ankle with one hand, and uses the index finger of the other hand to resist beneath the proximal phalanx of the great toe. Ask the patient to, “Bend your big toe over my finger. Hold it. Don’t let me straighten it.”

12. Grade 5 (Normal): completes full range of motion and holds against maximal resistance. Grade 4 (Good): completes available range of motion and holds against strong to moderate resistance. Grade 3 (Fair): patient completes available range of MP flexion of great toe but unable to hold against any resistance Grade 2 (Poor): completes only partial range of motion. Grade 1 (Trace): therapist my note contractile activity but no toe motion Grade 0 (Zero): no contractile activity Test For Grades 5, 4, 3, 2, 1 and 0

13.  Patient Position The patient is short sitting with legs hanging over the edge of the table. The ankle is in a neutral position 2- Toe MP Flexion (Lumbricales) Test For Grades 5, 4, 3, 2, 1 and 0  Therapist and Patient Instructions   The therapist is seated on a stool in front of the patient. The test foot rests on the examiner's lap. The therapist stabilizes the dorsum of the foot just below the ankle with one hand, and uses the index finger of the other hand to resist beneath the MP joints of the four lesser toes. Then patient actively flexes the toes at the MP joints, keeping the IP joints neutral. Ask the patient to, “Bend your toes over my finger.”

14. Grade 5 (Normal): completes full range of motion and holds against maximal resistance. Grade 4 (Good): completes available range of motion and holds against strong to moderate resistance.
