Common Distortion Patterns Flashcards
Pronation distortion syndrome
A postural distortion syndrome characterized by foot pronation (flat feet) and adducted and internally rotated knees (knock knees)
Lower crossed syndrome
A postural distortion syndrome characterized by an anterior tilt to the pelvis ( arched lower back)
Upper crosses syndrome
A postural distortion syndrome characterized by forward head and rounded shoulders
Pronation distortion short muscles
Gastrocnemius Soleus Peroneals Adductors Lliotibial head Hip flexor complex Biceps femoris (short head)
Pronation distortion syndrome lengthened muscles
Anterior tibialis Posterior tibialis Vastus medialiS Gluteus medius/Maximus Hip external rotators
Pronation distortion syndrome altered joint mechanics
Increased: knee adduction, knee internal rotation, foot pronation, foot external rotation
Decreased: ankle dorsiflexion and ankle inversion
Pronation distortion syndrome injuries
Plantar fasciitas
Posterior tibialis tendinitis (shin splints)
Patellar tendonitis
Low back pain
Lower crossed syndrome short muscles
Gastrocnemius Soleus Hip flexor complex Adductors Latissimus dorsi Erector spinae
Lower crossed syndrome lengthened muscles
Anterior tibialis Posterior tibialis Gluteus Maximus and medius Transversus abdominis Internal oblique
Lower crossed syndrome altered joint mechanics
Increased:
Lumbar extension
Decreased:
Hip extension
Lower crossed syndrome possible injuries
Hamstring complex strain
Anterior knee pain
Low back pain
Upper crossed syndrome short muscles
Upper trapezius Lavatory scapulae Sternocleidomastoid Scalenes Latissimus dorsi Teres major Subscapularis Pectoralis major/minor
Upper crossed syndrome lengthened muscles
Deep cervical flexors Serratus anterior Rhomboids Mid-trapezius Teres minor Infraspinatus
Upper crossed syndrome altered joint mechanics
Increased: cervical extension
Scapular protraction/elevation
Decreased: shoulder extension and shoulder external rotation
Upper crossed syndrome injuries
Headaches
Biceps tendonitis
Rotator cuff impingement
Thoracic outlet syndrome
