25
what are causes/ factors that contribute the development of secondary respiratory sequelae
1. expiratory ms weakness 2. altered level of consciousness w concomitant head trauma or meds 3. ileus 4. failure to spontaneously sigh 5. bronchial mucus hypersecretion 6. associated rib fx 7. associated thoracoabdominal surgery 8. dysphagia and aspiration associated w tracheostomy or cspine surg w ant approach
26
how can ileus lead to secondary respiratory sequelae
ileus - temp lack of intestinal ms w inc diaphragmatic excursion and inc risk of aspiration of gastric contents
27
why is bronchial mucus hypersecretion seen in 20% acute cspine SCI
impaired peripheral sympathetic nervous system
28
what can cause a DVT in general
dec rate of blood flow damage to blood vessel wall inc tendency of blood to clot
29
why is there an inc risk of DVT in SCI
immobilization unable to move UE or LE d/t: - absent strength - impaired vasomotor control* - fx
30
what are considerations for PT since population has inc risk of DVTs
TEDS, ace wraps, venodyn boots see if IVC filter placed on anti-coag therapy
31
what is the concern of DVTs in this population
it traveling and becoming PE - partial or complete lung obstruction
32
what are sx of the onset of a PE
sudden sx of: SOB tachycardia chest pain blue tinge to fingers, toes, lips
33
what is heterotopic ossification (HO) and what can this be d/t
inc bone growth/calcification around joint (aka inc bone where shouldn't be) d/t trauma or hit to bone
34
when does heterotopic ossification present in SCI
3-12wks post injury
35
sx of heterotopic ossification
swelling changes in end feel (-> bony) dec ROM inc in temp around area redness
36
where are the 4 most common sites of heterotopic ossification
most hips knees shoulders elbows least
37
what are common causes of UTIs in SCIs
common w voiding dysfunction - bacteria enters bladder while catheterizing - delayed use of toilet - incomplete emptying of urine
38
what are first signs of a UTI in SCI
fever chills pain w urination acute cog changes inc spasticity (UTI = nox stim)
39
why is OH common in SCI
interruption of CV sensory input to brainstem and sympathetic nervous system in SC -> loss of vasomotor control -> blood vessels not able to vasoconstrict effectively to counteract change in pressure --> venous pooling --> inc in HR w pressure change isn't enough to counterbalance drop in BP
40
what are PT interventions/considerations with OH
wear compression stockings and abdominal binder tilt table and monitor VS
41
when would we see an order for Midodrine and why is this helpful for PT
treats low bp / HoTN admin prior to therapy only in people whos low bp severely limits ADLs OH can limit progression in therapy if dropping every time we do activity
42
what is the most costly and frequent secondary complicaiton
pressure sores
43
what are common sites of pressure sores
bony prominences - sacrum/coccyx - heels - greater troch - ischial tub - scap
44
what impacts does pressures sores have
mobilty positioning / off loading QOL
45
where does sympathetic vs parasympathetic system live
sympathetic - tspine para - brain
46
what is the cause of autonomic dysreflexia
SCIs above T6 - interrupts sympathetic splanchnic outflow and the pathological autonomic reflex --> leads to an abnormal response to noxious stim and sends body into fight or flight
47
what are examples of a noxious stim that may trigger autonomic dysreflexia and what is the most common
***bowel/bladder distention/irritation **** pressure sore restrictive clothing cutaneous stim DVT sex labor sunburn bug bite estim fx
48
what are s/sx of autonomic dysreflexia
HTN bradycardia pounding HA red/blotchy face blurry vision constricted pupils
49
what do you do if someone goes into autonomic dysreflexia
find and correct source of noxious stim sit person upright if possible - trying to dec BP - call for assistance ASAP this is a red flag
50
why is autonomic dysreflexia a red flag
can be fatal bc can stroke out when goes into HTN as HR slows down
51
what are 4 common causes of death post SCI
1. respiratory complications - pneumonia / PE 2. CV dz and autonomic dysfunction 3. external causes - subsequent injuries, homicide, suicide (most common) 4. wound infection
52
what are spinal precautions
no excessive bending/twisting maintain log roll always - spine in neutral alignment for mobility, no segmental no lifting >10# or what indicated by MD c collar worn always or per MD order
53
what is an important part of following spinal precautions w pts
vary MD to MD and depending on pt - ask when they need the brace/collar on and when is it okay not to
54
what are acute care PT priorities
pain respiratory / ventilation integument sensation ms performance ROM ms tone and DTR functional status
55
nociceptive vs neuropathic pain
nociceptive: - msk and visceral - from activation of nerve endings or nociceptors in peripheral tissues neuropathic: - direct consequence of lesion or dz affecting somatosensory system / injury to nerves themselves - very common in SCIs
56
how does neuropathic pain present
tingling burning electric shock cold pricking pins and needles squeezing sharp/shooting
57
what are 2 ways to assess pain
VAS - visual analog scale NPS - neuropathic pain scale
58
what are treatments for neuropathic pain and what is the challeng w them
difficult to treat pharm: antileptics (gabapentin), tricyclic antidepressants, anticonvulsants, opioids, cannabinoids, baclofen non-pharm: positioning, surgical (ie nerve block), TENS, acupuncture
59
how can TENS help to treat neuropathic pain and what is limitation
stimulating nerve endings TENS units are like bandaids - helps them function while it is on and dec pain - doesn't carryover when you take off
60
what are characteristics of respiratory/ventilation PT addresses acutely
function of respiratory ms chest expansion breathing pattern cough vital capacity
61
what impact does the position have on breathing in higher level SCI and why
more difficult in sitting - diaphragm when innervated sits in a biomechanically advantaged position - however if higher injury, diaphragm sinks down and pushes organs down and out in sitting in supine - gravity pulls organs in and up & provides support for diaphragm for breathing and makes it easier
62
what are 4 considerations that impact skin integrity
1. absent or impaired sensation 2. loss of normal motor function - dec ability to self reposition 3. loss of normal sensation - disrupts feedback of discomfort/pain w position 4. impaired circulation and ms atrophy - edema - less protection/padding at bony prominences
63
what are 3 external causes of skin breadown
trauma moisture friction
64
what sensation info do we want to test / collect
detailed exam of both superficial and deep sensations - LT - pin prick - proprioception
65
what are the 2 types of sensation testing that are especially used to classify sensory level of lesion
LT and pin prick
66
what is key to assessing ms performance and why
palpation common ms substitutions used (make sure mobilizing prox joint)
67
what ms should be tested
other than "key ms" in ASIA: - ms groups throughout myotomes w intact innervation
68
what are ROM considerations
pt positioning pain limitations other trauma sensory integ tone functional impact
69
where should extreme caution be used when performing MMT and PROM exam and why
neck and shoulders in tetraplegia lower trunk and hips in parapleg could causes secondary trauma to soft tissues (esp after surgery) if pushing PROM into end range too much
70
who is an important interprofessional team member to work w for ROM and on what
OT facilitating and maintaing optimal positioning - & tenodesis grasp in above C6
71
what is documented with regard to the ms tone assessment
quality, involved ms groups, factors that inc or dec tone use modified ashworth
72
what are recovery considerations with examining ms tone
time since injury spinal shock - dec tone during those phases emerging tone - may inc over time pt can also experience spasms throughout continuum of care which can be very painful
73
what 5 DTRs are most commonly examined
biceps (C5) ECRL (C6) triceps (C7) quads (L3) gastroc (S1)
74
when is the detailed functional exam usually performed and why
often deferred until acute rehab phase when pt is medically stable and cleared for activity (depends on medical status)
75
what is the goal w assessing and intervening on functional status
get pt to tolerate verticality and have proper hemodynamic response (aka not OH) to that position
76
what is assessed in the functional status exam
ability of pt to tolerate upright and OOB mobility with: - head of bed - chair position of bed - OOB lift to loaner chair w cushion
77
what is an important consideration to be aware of with a functional status assessment
any contraindications or precautions to mvmt
78
what is the purpose of dependent, non-skilled transfers via lift or body slide boards (3)
get pt out of bed to: - inc tolerance for upright - for skin integ - optimize pulm function
79
how does the SCI level impact the bladder/bowel dysfunction seen
spastic = higher lesion areflexic = lower lesion
80
what type of postural deformity is often seen in SCI and why is this problematic
post pelvic tilt problematic bc inc pressure on sacrum and ischial tubs - also problematic for sliding out of chair
81
what are other complications seen along the continuum of care
CV impairments edema OP and skeletal fx bladder/bowel dysfunction postural deformity overuse injuries thermoregulation abnormalities depression sexual dysfunction
