What is the 3 things you should look at when observing posture?

1- Lumbar spine (sway back, flat back, lordosis, kyphosis)

2-Pelvis (posterior versus anterior tilt)

3- Plumb line between ear- shoulder- hip (should be aligned)

Patients with excessive lordosis don’t like to? Reduced lordosis?

Study These Flashcards

Excessive- don’t like to stand for a prolonged period

Reduced- don’t like to sit for a prolonged period

What are 3 things you should look at when viewing posture from a posterior view?

Study These Flashcards

Muscle bulk (see if it is even bilaterally)

Arm window crease (should be roughly the same bilaterally)

Creases in skin (if you see a large crease patient may prefer to bend/ move more from that area)

3 things to look at when assessing sitting posture from a Sagittal view?

Study These Flashcards

Hip flexion (look at GT to ASIS)
Pelvic position (posterior vs. anterior tilt)
Position of lumbar spine

_ _ anterior tilt is considered normal. - _of hip flexion is considered to be normal in sitting, if less than _ _ they are?

Study These Flashcards

10 DEGREE anterior tilt is considered normal (standing)

100-110 DEGREES of hip flexion is considered to be normal in sitting, if less than 90 DEGREES they are going to compensate with flexion in the lumbar or thoracic spine.

When bending over to pick something off of the floor, what is considered a normal range of trunk flexion?

Study These Flashcards

Normal 30-40 DEGREES of trunk flexion

Glut/ Hip progression- Level 0: _ _ and _ _ activation, and then _ and _ _.

Study These Flashcards

UPPER ABDOMINAL and LOWER ABDOMINAL activation, and then FULL and SIDE PLANK.

What is the overall goal for the Level 0?

Need to be able to feel the correct muscles working

Glut/ Hip progression- level 1 (_, _ _): _, side lying _ _, and _ _.

Level 1 (OKC, SINGLE LIMB): - CLAMS - side lying HIP ABDUCTION - FIRE HYDRANTS

_/ _ contraction helps increase recruitment of muscle fibers.

ACTIVATION/ ISOMETRIC contraction helps . . .

In the Hip/ glut progression patients should begin at?

Should begin at whichever level they cannot perform, and then start at the level before that

What is the 'ideal' dosage for the Level 1 glut/ hip progression exercises? How should you end the session?

Hold 1 MINUTE, for 3 SETS, with THERABAND (increase as strength increases) Break in between (break should the same amount of time as the hold) You should end the session by setting goal that you expect the client to be able to achieve by next meeting

Glut/ Hip progression- Level 2 (_, _ _): _, and _ _.

Level 2 (CKC, DOUBLE LIMB): - SQUATS - SURFER SQUATS

What can you add to Level 2 exercises to increase glut activation? How should you determine the best stance for your patient to assume for squats?

You can add THERABANDS to increase glut activation Best stance: can determine by using QUADRUPED ROCKING test, and determine which position allows the patient to have the most hip flexion ROM.

Describe surfer squats.

Perform general squat -rotate one leg externally, 45 degrees (Pelvis should remain level, split the difference between rotated and leg and non rotated leg with trunk)

What is the dosage for squats? Surfer squats?

Squats- ONE MINUTE with good form, 3 SETS Surfer squats- HOLD FOR ONE MINUTE, BOTH LEGS, 3 SETS

Hip/ Glut progression Level 3(_, _ _)- _ _ _ _. What is the ideal position? (4)

Level 3 (SINGLE LIMB- standing, OKC)- SINGLE LEG FIRE HYDRANTS Ideal position: mini squat, with 45 DEGREES of ABDUCTION, EXTENSION, AND ER

Quad/ Glut progression Level 4 (_ _, _ limb)- _ and _ _. How does this level differ from prior levels?

Level 4 (DYNAMIC STRENGTHENING, DOUBLE limb)- SQUATS and MONSTER WALKS. This level is different from prior levels in that there is now movement, not just isometric hold.

What is the dosage for the Level 4 Squat exercises?

Look for failure/ fatigue (either loss of form, or patient gets tired) - use that # for reps per set, 3 sets (will be individual to patient) - reps may vary depending upon leg, band color used, and exercise

What is the dosage for level 4 monster walks? AKA? (2)

Mark the distance that patient achieved while still maintaining good form, use that # as basis for reps.

Hip and Glut progression Level 5 (_ _, _ limb): _ _, _ _ and _ _.

Level 5 (DYNAMIC STRENGTHENING, SINGLE limb) - DROP LUNGE (single leg squat with to touch behind) - STEP UPS - STEP DOWNS

Hip and glut progression Level 6 (_ limb _): _ _

Level 6 (DOUBLE limb PLYOMETRICS): DROP JUMPS (two legs)

Glut and Hip progression Level 7 (_ limb _): _ _

Level 7 (SINGLE limb PLYOMETRICS): BOX JUMPS (one legged)

What is the overall goal for a glut/ hip progression? How long will the progression take?

Overall goal: DEVELOP A 45 MINUTE HEP How long will it take? DEPENDS ON PATIENT, AND WHAT THEY NEED TO BE ABLE TO DO

With Levels 1-3: exercises should be performed? How long should each level take to progress? What if they don't?

Should be performed: DAILY, FOR 45 MINUTES How long to progress: APPROXIMATELY 1 WEEK PER ACTIVATION PHASE If patient can not handle a 45 minute HEP, or does not have time- meet them where they can (ex. 15 minutes) and build -MAY NEED TO SPREAD OUT VISITS IN ORDER TO REACH DOSAGE GOALS

With levels 4-5: exercise program (45 min) should be performed? Exercises from previous levels should be?

Level 4-5 exercises: should be performed EVERY OTHER DAY Exercises from previous levels (1-3), should be USED AS A WARM UP

With levels 6-7: Exercises should be performed for 45 min, _ _ per _. With these levels you should not _ _ _, run the risk of _.

Exercises should be performed for 45 minutes, 2/3 TIMES PER WEEK With these levels you should not EXERCISE TO FATIGUE, run the risk of INJURY

What is the best posture?

One that changes

What are 2 common pathomechanical patterns seen with gait?

Frontal and transverse plane mechanics
