Q

what is the typical positioning of the scapula?

Study These Flashcards
A

~2 inches lateral from the spine (frontal plane - medial/lateral positioning)
T2-T7 (frontal plane - superior/inferior position)

25
what is the most common postural defect in the upper extremity that requires correction?
forward (rounded) shoulders (acromion anterior to the line of gravity)
26
what is the normal carrying angle formed by humeral and forearm axes for males and females?
males: 5-10 degrees females: 10-15 degrees
27
what are some examples of lower extremity observations you may see?
femoral internal rotation knee varus/valgus knee hyperextension arch height calcaneal position toe out/in angle toes sign
28
what is the definition of valgus?
distal segment away from midline
29
what is the definition of varus?
distal segment towards midline
30
what are the technical names of the differentiating foot arch types and what do they mean?
pes planus - flat foot pes cavus - high arch
31
what is the too-many-toes sign a signal of?
excessive pronation
32
what toes should you be able to see with a normal hindfoot approach?
5th and 1/2 of the 4th
33
what are some common spinal observations?
cranial extension/tilt cervical lordosis thoracic kyphosis lumbar lordosis PSIS/iliac crest height
34
what is normal cervical lordosis and what is its most common postural defect requiring correction?
30-35 degrees forward head posture
35
what is normal thoracic kyphosis?
40 degrees
36
what is normal lumbar lordosis and what is its most common postural defect requiring correction?
45 degrees increased anterior pelvic tilt
37
what level should the iliac crest fall at?
LV4
38
what level should the PSIS fall at?
S2
39
what is a neutral position of the pelvis?
ASISs are in the same horizontal plane, and the ASIS and symphysis pubis are in the same vertical plane
40
what does an increased anterior pelvic tilt cause?
increased lordosis of the lumbar spine
41
what does an increased posterior pelvic tilt cause?
flattening of the back/lower lumbar spine
42
what is the idea of crossed patterns and how does it relate to the cervical spine and neck muscles?
tight upper traps/levator scapulae and SCM/pectoralis results in a weak middle trap/lower trap/serratus anterior and deep neck flexors (and vice versa)
43
what is the definition of scoliosis and how is it named in relation to side affected?
lateral curvature of the spine C-curve: curvature named to the convex side of the curve
44
is right or left thoracic curve most common?
right
45
is scoliosis more common in boys or girls?
girls
46
what is the most common age of onset for scoliosis?
10-14 years old
47
what are some clinical manifestations of a scoliosis posture?
rib cage asymmetry and/or rib hump when bending forward uneven shoulder and/or pelvic height prominence of scapula/hip difference in space between arms and trunk when standing apparent leg-length discrepancy
48
the body develops a compensatory curve to maintain what three things wthin the body? (typically found with scoliosis)
posture balance equilibrium
49
can functional scoliosis be corrected, and if so, how?
yes, corrected through active shift in posture but it can become structural over time
50
what is the difference in structural and functional scoliosis?
structural cannot be corrected actively - it is a composition of the body structure
51
what is the name of the test used to assess scoliosis and how is it performed?
adam's forward bend test knees fully extended, hands to side bend forward to a horizontal position and document asymmetry with a scoliometer 7 degrees on a scoliometer = 20 degrees on a x-ray
52
what are some components of clinical reasoning for postural assessments?
examine postural orientation in standing, sitting, and dynamically from more than one plane to identify areas for investigation assess for flexibility and muscle length assess impacts of muscle strength
53
is there evidence that prolonged standing, walking, and sitting at work is associated with LBP?
no
54
is there evidence that there is a relationship between posture and neck pain in adolescents?
no
55
should all deviations of posture be considered pathological?
no
56
in order to determine the effect on the patient's symptoms, traisl should be performed between ______ active correction and ________ passive correction
patient active, clinician/therapist passive
57
what is proper sitting posture?
feet comfortably flat on floor hips and knees flexed to roughly 90 degrees back of the chair inclined roughly 10 degrees armrests allows elbow flexion at about 90 degrees
58
what kinds of movements can help to alleviate the stress and strain associated with prolonged sitting?
simple extension movements and/or occasionally standing up
