Is “Snoozing” Bad? • http://www.cnn.com/2014/02/06/health/upwave-snooze-button/index.html?hpt=he_t4
Homework Review • Upper Extremity Worksheet
Movements of the Hip • What are the movements of the hip? • Flexion • Extension • Abduction • Adduction • Medial Rotation • Lateral Rotation • Circumduction
Muscles of Hip Flexion • Rectus Femoris (quad muscle) • Pectinius • Psoas Major
Muscles of Hip Extension • Gluteus Maximus • Hamstrings • Semimembranosus • Semitendinosus • Biceps Femoris
Muscles of Hip Abduction • Tensor Fascia Latae • Iliotibial Band (IT Band)
Muscles of Hip Adduction • Adductor Magnus • Adductor Brevis • Adductor Longus
Muscles of Medial/Lateral Rotation MEDIAL • Adductors • Magnus • Longus • Brevis • Semimembranosus • Gluteus Medius LATERAL • Biceps femoris
Psoas Major • Origin: T12 and lumbar vertabrae • Insertion Lessor trochanter of femur • Action Flexor of hip or thigh on pelvis
Semimembranosus • (Deep to Semitendinosus) • Origin: Ischial tuberosity • Insertion: Proximal tibia • Action: Extends thigh; flexes knee, medially rotates
Tensor FascaeLatae • Origin: Iliac crest • Insertion: IT band tract • Action: Medial rotation, abduction
Adductor Magnus • Origin: Ischial and pubic rami • Insertion: Adductor tubercle of femur • Action: Adduct and medially rotate and flex thigh
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
Movements of the Knee • What directions does the knee move? • Flexion • Extension • NO rotation
Muscles of Knee Flexion • Remember, flexion is the decrease in angle size • Heel to butt • 3 Hamstring muscles • Semimembranosus • Semitendinosus • Biceps Femoris
Muscles of Knee Extension • How many muscles are in the quadriceps? • 4 • Rectus Femoris • VastusMedialis • VastusLateralis • VastusIntermedius
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)
Injuries of the Knee • Patella Tracking Syndrome • Patella Tendonitis (Jumper’s Knee) • Medial Tibial Stress Syndrome • Shin Splints • Achilles Rupture
