Presentation Transcript

  1. Muscles of the Hip/Thigh

  2. Is “Snoozing” Bad? • http://www.cnn.com/2014/02/06/health/upwave-snooze-button/index.html?hpt=he_t4

  3. Homework Review • Upper Extremity Worksheet

  4. Movements of the Hip • What are the movements of the hip? • Flexion • Extension • Abduction • Adduction • Medial Rotation • Lateral Rotation • Circumduction

  5. Muscles of Hip Flexion • Rectus Femoris (quad muscle) • Pectinius • Psoas Major

  6. Muscles of Hip Extension • Gluteus Maximus • Hamstrings • Semimembranosus • Semitendinosus • Biceps Femoris

  7. Muscles of Hip Abduction • Tensor Fascia Latae • Iliotibial Band (IT Band)

  8. Muscles of Hip Adduction • Adductor Magnus • Adductor Brevis • Adductor Longus

  9. Muscles of Medial/Lateral Rotation MEDIAL • Adductors • Magnus • Longus • Brevis • Semimembranosus • Gluteus Medius LATERAL • Biceps femoris

  10. Psoas Major • Origin: T12 and lumbar vertabrae • Insertion Lessor trochanter of femur • Action Flexor of hip or thigh on pelvis

  11. Semimembranosus • (Deep to Semitendinosus) • Origin: Ischial tuberosity • Insertion: Proximal tibia • Action: Extends thigh; flexes knee, medially rotates

  12. Tensor FascaeLatae • Origin: Iliac crest • Insertion: IT band tract • Action: Medial rotation, abduction

  13. Tensor Fasciae Latae

  14. Adductor Magnus • Origin: Ischial and pubic rami • Insertion: Adductor tubercle of femur • Action: Adduct and medially rotate and flex thigh

  15. Adductor Magnus

  16. IT Band Syndrome • IT Band connects from the Tensor FascaeLatae to the Lateral knee • Very important in leg stabilization while running • Common injury to the IT band from running, cycling, and heavy squatting • Inflammation caused by continual rubbing of IT band over lateral femoral epicondyle from flexion/extension

  17. Quad/Knee/Calf

  18. Movements of the Knee • What directions does the knee move? • Flexion • Extension • NO rotation

  19. Muscles of Knee Flexion • Remember, flexion is the decrease in angle size • Heel to butt • 3 Hamstring muscles • Semimembranosus • Semitendinosus • Biceps Femoris

  20. Muscles of Knee Extension • How many muscles are in the quadriceps? • 4 • Rectus Femoris • VastusMedialis • VastusLateralis • VastusIntermedius

  21. Muscles of the Calf (action) • Calf muscles deal with ankle movement • Gastrocnemius (plantar flexion) • Crosses ankle and knee • Solus (plantar flexion) • Crosses only ankle • Say you have a tight calf, but you are unsure which muscle to stretch. How could you stretch one and not the other? (HINT: Has to do with what joints they cross)

  22. Injuries of the Knee/Calf

  23. Injuries of the Knee • Patella Tracking Syndrome • Patella Tendonitis (Jumper’s Knee) • Medial Tibial Stress Syndrome • Shin Splints • Achilles Rupture

  24. Patellar Tracking Syndrome

  25. Patellar Tendonitis

  26. Medial Tibial Stress Syndrome

  27. Achilles Rupture
