  1. Weakness of this muscle causes eccentric overload to the tibialis posterior, soleus and flexor hallucis in deccelerating pronation at heel strike
    Tibialis Anterior
  2. Weakness of this muscle causes increased hip flexor activity during swing phase (to clear the foot from theground), resulting in increased shear in the lumbosacral region
    Tibialis Anterior
  3. This muscle may be overloaded with a weak glut max (inhibited by tight psoas) or medius (inhibited by SI joint dysfuction) in decelerating tranverse or frontal plane pronation of the limb at heel strike. 
    Tibialis Posterior
  4. Weakness in this muscle increases frontal and transverse plane stress to the knee, resulting in patellar tendonitis or medial patellofemoral pain
    Tibialis Posterior
  5. Weakness in this muscles increases transverse plane stress in the lumbo-pelvic-hip complex, leading to SI joint problems 
    Tibialis Posterior
  6. Weakness in this muscle may cause an increase in eccentric overload to the opposit posterior shoulder muscles
    Tibialis Posterior
  7. Weakness in this muscle leads to tissue overload of the tibialis posterior, FHL and FDL
    Soleus
  8. Tightness in this muscle decreases sagittal plane dorsiflexion, resulting in increased frontal and transverse plane compensations of the entire kinetic chain (requires muscles to work harder and longer eccentrically)
    Soleus
  9. This muscle is overloaded in the presence of weak, proximal hip external rotaters (in deceleration of femoral internal rotation during pronation of the limb)
    Gastrocnemius 
  10. Tightness in this muscle decreases available dorsiflexion range resulting in frontal and transverse plane compensations during prontation of the limb
    Gastrocnemius
  11. This muscle can become tight with prolonged plantarflexed positions (wearing heels, standing with knees hyperextended)
    Gastrocnemius
  12. Weakness of this muscle allows excessive or prolonged supination, leading to decreased shock absorption at heel strike. This increases lumbosacral compession forces that may contribute to lumbar or sacroiliac dysfunction. 
    Peroneus Longus
  13. These 2 muscles may be chronically irritated (tissue overload) when subtalar joint eversion is limited (common following ankle sprain or a shorter lower extremity)
    Peroneus Longus & Brevis
  14. These 2 muscles are dependent on STJ supination/inversion for optimal length tension in decelerating MTJ dorsiflexion and first ray stabilization at push-up. 
    Peroneus Longus & Brevis
  15. Weakness in this muscle creates eccentric overlad to the patellar tendon
    Quadriceps
  16. Tightness of this muscle may result in an anterior pelvic tilt, which inhibits gluteus maximus (causing hamstring overload)
    Rectus Femoris
  17. Tightness of this muscle may cause quadricep tightness (increased neural gain), creating increased tension of the patellar tendon (causing tendonitis)
    Iliopsoas
  18. Tightness of this muscle may cause a posterior pelvic tilt and a functional leg length discrepancy.
    Hamstrings
  19. This muscle becomes overactive with a weak glut max (usually inhibited by a tight psoas)
    Bicep Femoris
  20. Tightness in this muscle may create dysfunction of the proximal tib/fib joint, limiting knee flexion or ankle dorsiflexion
    Bicep Femoris
  21. Tightness of this muscle increases frontal plane stress at the knee/hip
    Adductors
  22. This muscle may become tight with limited STJ eversion, causing tissue overload during weight transfer to opposite limb (chronic adductor/groin strains)
    Adductors
  23. Tightness in this muscle may cause gluteus medius inhibition, leading to compensations of quadratus lumborum and TFL/ITB for frontal lane stabilization. 
    Adductors
  24. Studies indicate decreaed EMG activity of this muscle following ankle sprains, leading to synergistic dominance of TFL and gluteus minimus
    Gluteus Medius/TFL
  25. SI joint dysfunction leads to arthokinematic inhibition of this muscle
    Gluteus Medius
  26. Overuse of this muscle may lead to superior gluteus nerve entrapment, causing pain reference to the lateral knee
    Gluteus Medius
  27. Overuse of this muscle can create an anterior pelvic tilt, altering length/tension of gluteus maximus (inhibition)
    TFL
  28. This muscle is inhibited by...
    -Tight Iliopsoas
    -Synergistic dominance of hamstrings
    -Effecting proximax tib/fib joint
    Glut Max
  29. Inhibition of this muscle results in synergistic dominance of erector spinae and piriformis (causing SIJ dysfunction and neurovascular compression pathology)
    Glut Max
  30. Weakness in this muscle may cause patellar tendonitis (decrease in deceleration of hip flexion/adduction/IR necessitates an increase in quadriceps activity to decelerate knee flexion/adduction/IR)
    Glut Max
  31. Weakness in this muscle may cause tibialis posterior tendonitis and plantar fascitis (as this muscle aids in deceleration of tibial rotation due to its attachment in the ITB)
    Glut Max
  32. Weakness in this muscle may cause achilles tendonitis (gastroc/soleus become synergistically dominant in deceleration of l/e rotation during pronation)
    Glut Max
  33. Tightness of this muscle inhibits glut max & increases compressive forces of the lumbar spine. 
    Psoas
  34. Tightness of this muscle inhibits lumbo-pelvic-hip complex stabilization mechanism which increases translational and rotational stress. 
    Psoas
  35. Tightness of this muscle causes external rotation, which may result in posterior hip capsule tightness (limiting internal rotation and causing anterior capsule impingement)
    Psoas
  36. Tightness in these muscles create SI joint dysfunction (sacral torsions) leading to lumbar/spine dysfunction)
    External Rotators (Piriformis/Obturator Internis)
  37. These muscles become synergistically dominant in the presence of a weak glut max (inhibited by tight psoas), weak bicep femoris (anterior pelvic tilt) and/or weak gastrocnemius (also decelerator of femoral internal rotation)
    External rotators (piriformis/Obterator Internis)
