FLExOR DIGITORIuM LONGuS
Joint Action performed by the Second through fifth distal interphalangeal joint
- Flexion
Joint Action performed by the second through fifth metatarsophalangeal joints
- Flexion
Joint Action performed by the Ankle and Foot
- Plantar flexion
- Inversion (assisted) – respectively
For example it points second through fifth toes down
Origin: Tibia – Posterior aspect - Fascia covering tibialis posterior
Insertion: Second through fifth distal phalanges – Bases
Common distortions caused by weakness is over-pronation
FLExOR DIGITORuM BREVIS
Joint Action performed by the Proximal interphalangeal joints
- Flexion
Joint Action performed by the Metatarsophalangeal joints
- Flexion (assisted)
For example it points toe down
Origin: Calcaneal tuberosity – Medial process - Plantar fascia
Insertion: Second through fifth middle phalanges
Common distortions caused by weakness is a lack of support for the longitudinal
and transverse arches
