Exercise Interventions for the Hip and Pelvis Flashcards
What muscles flex the hip
Prime Movers: iliopsoas, rectus femoris, TFL, & sartorious
2ndry Movers: pectinous, adductor longus, adductor Magnus, & gracilis
What muscles extend the hip
Prime Movers: glute max & hamstrings
2ndry Movers: glute med (posterior fibers), adductor Magnus, & piriformis
What muscles abduct the hip
Prime Movers: glute med, glute min, &TLF
2ndry Movers: piriformis, sartorius, & rectus femoris
What muscles adduct the hip
Prime Movers: adductor Magnus, adductor longus, adductor brevis, gracilis, pectineus
2ndry Movers: biceps femoris (long head), glute max (posterior fibers), quadratus femoris, & obturator externus
What muscles externally rotate the hip
- obturator internus
- obturator externus
- gemellus superior
- gemellus inferior
- quadraus femoris
- piriformis
- glute max
What muscles internally rotate the hip
No prime movers
2ndry Movers: glute med (anterior fibers), glute min, TFL, adductor longus, adductor brevis, adductor Magnus (posterior fibers), & pectineus
Describe anterior pelvic tilt and posterior pelvic tilt
Anterior Tilt: results in hip flexion & increased lumbar spine extension
Posterior Tilt: results in hip extension & increased lumbar flexion
Order of events for lumbopelvic rhythm flexion
1) head & upper trunk initiate flexion
2) pelvis shifts posteriorly to maintain COG over BOS
3) trunk continues to forward bend until 45 degrees where posterior structures become taut resulting in passive tension
4) pelvis begins to rotate forward (anterior tilt) controlled by glute max & hamstrings
5) pelvis rotates forward until full ROM
6) final ROM in forward bending is dictated by the flexibility of the various back extensor muscles, fascia. & hip extensor muscles
Order of events for lumbopelvic rhythm extension
1) return to upright position: hip extensor muscles rotate the pelvis posteriorly resulting in posterior tilt
2) back extensor muscles extend the spine from lumbar region upward
3) variations in the normal synchronization of this activity occur because of training, faulty habits, restricted muscle or fascia length, or injury & faulty proprioception
Functional relationships of the LE for hip flexion/extension
- accompanied by knee flexion & ankle DF
- controlled by glute max/hamstrings, quads, & gastric/soleus
Functional relationships of the LE in hip abduction/adduction
-unilateral WB gravity creates a ADD moment requiring glute med to activate
- weakness may create an ADD moment on the femur with increased knee valgus resulting in increased patella femoral joint stress
Functional relationships of the LE in hip rotation
- Hip IR = femur IR, eversion of calcaneus, & pronation of foot
- Hip ER = femur ER, inversion of calcaneus, & supination of foot
Describe open chain
- independent joint movement
- movement of body segments distal to joint moving
- typically non-weight bearing
- external rotary loading
- external stabilization required
- Goals: isolation of muscle groups, control of movements, & carryover to function/injury prevention
Describe closed chain
- movement of adjacent joints
- movement of distal & proximal body segments to joint moving
- typically weight bearing
- axial loading
- internal stabilization by co-contraction
- Goals: joint approximation, co-activation/dynamic stabilization, proprioception, & carryover to function/injury prevention
What is a critical cue for hip abduction exercises
- avoid excessive flexion & ER of the thigh as this results in the TFL overpowering the glute med and min
Open chain therex for hip abduction
- isometric hip ABD
- supine ABD (gravity eliminated)
- standing ABD (gravity minimized)
- side lying ABD (against gravity)
Open chain therex for hip extension
- glute maximus focus
- isometric glute squeezes
- standing trunk flexion on supported surface with hip extension + knee flexion (donkey kick)
- standing hip extension
- quadruped leg lifts with hip extension + knee flexion
- prone hip extension + knee flexion
What exercises activate glute med the most
- side-lying hip abduction
- single limb squat
- lateral band walk
What exercises activate glute max the most
- single limb squat
- single limb deadlift
- transverse lunge
Proper cue for patient performing prone isometrics for hip ER
- bend knees & push your heels together
- Clam Shell
- Reverse Clam Shell: IR focused lifting heel up to the ceiling
Exercises for hip flexion focused on iliopsoas & rectus femoris
- supine heel slides
- SLR hip flexion
- psoas march: no resistance, light resistance, or bridge + march
Describe a 3 way and 4 way open chain hip exercise
- 3 Way: ABD, flexion, and extension with a band in standing
- 4 Way: ABD, ADD, flexion, and extension with a band in standing
Closed chain therex for the hip
- alternating isometrics & rhythmic stabilization
- single limb stance
- hip hiking/pelvic drop
- bridging
- wall slides (squat)
- partial squats or mini squats
- body weight squats
- single limb deadlift (hip dominant)
- single limb squats (knee dominant)
- step/step down
- partial or full lunges
- resisted side stepping or resisted side sliding
Functional progression of the hip
- balance progressions (BLE full WB to unilateral, sagittal/frontal plane UE movements to transverse/diagonal planes, perturbation activities from stable/unstable surfaces)
- ambulation progressions (uneven surfaces, turning, backward walking)
- body mechanics: lifts, carry, lunges, squats, pushing/pulling
- agility drills & plyometrics
Stretching interventions for the hip
- Thomas test stretch (leg hangs off end of table)
- Modified fencer stretch
- Kneeling fencer stretch
- Stretch to increase hip IR (cross bent leg over other leg and use elbow to help rotate trunk)
- Standing quad stretch
- Hamstring stretch in doorway
- Hamstring stretch half seated on table and half standing
- Piriformis stretch
- Butterfly stretch
