pelvis
| Question | Answer |
|---|---|
| define the pelvic gurdel | right & left innominate bones, sacrum coccyx |
| appendicular skeleton | right &left innominate bone |
| Axial skeleton | sacrum |
| the innominate bone is made of three fused bones | ilam, ischium pubis |
| the pelvic girdle consists of three joints | lumbosacral, between L5 and S1, sacroiliac, pubis symphysis |
| Pelvic movement | Sacrum |
| Nutation Reference point | superior aspect of the sacrum |
| when dose Nutation occurs | trunk flexion or anterior pelvic tilt |
| Counter nutation Reference point | superior aspect of the sacrum |
| when dose counter nutation occurs | trunk extension or posterior pelvic tilt |
| Anterior pelvic tilt reference point | ASIS & pubic symphysis |
| Anterior pelvic tilt | ASIS is anterior to the pubic symphysis |
| Posterior pelvic tilt reference point | ASIS & pubic symphysis |
| Posterior pelvic tilt | ASIS is posterior the the pubic symphysis |
| Lateral pelvic tilt reference point | Iliac crest |
| Lateral pelvic tilt is identified by | the side of the pelvis that is lower |
| Right lateral pelvic tilt | the right side is lower |
| Left lateral pelvic tilt | the left side is lower |
| Pelvis elevation ( Hip Hike) reference point | Iliac crest |
| Pelvis elevation ( Hip Hike) is identified by | the side of the pelvis that is higher |
| what muscles require Pelvis elevation ( Hip Hike) | the contralateral QL and hip abductors |
| Pelvic rotation reference point | ASIS |
| Pelvic rotation is identified by the | The ASIS that is MOST anterior |
| Anterior pelvic positioning Muscles weak/overstretched | trunk flexors & Hip extensors |
| Anterior pelvic positioning Muscles short / tight | Hip flexors & trunk extensors |
| Posterior Pelvic positioning Muscles weak/overstretched | Trunk extensors & hip flexors |
| Posterior Pelvic positioning Muscles short /tight | Trunk flexors /hip extensors |
