integumentary: skin infection, wounds
eye: galucoma, cataracts, retinopathy
feet
CVA
nephropathy
CV: HTN
ketoacidosis medical emergency

18
Q

PT considerations for DM wounds

A

daily routine/activites
footwear
foot deformities
prior Hx of infections, surgery
neuropathy
caludications
current wounds location, onset, trauma, history of same location
compare to uninvolved foot
pain response

19
Q

diabetic foot characteristics

A

size/deformity
rounded
deep wounds
maceration around wounds from drainage
callused
red wounds
heavy drainage

20
Q

Wagner ulcer classification

A

0-5
0: intact
1: superficial ulcer, no subcutaneous
2: deep ulcer involving subcutaneous, tendon or bone exposure
3: deep infected ulcer including abscess
4: partial foot gangrene affecting digits
5: full foot gangrene requiring surgery

21
Q

DM MSK examination

A

ROM/strength BL
contractures
foot deformities

22
Q

common foot deformities in DM

A

claw toe: MTP hyperextension, PIP/DIP flexion
hammer toe: MTP hyperextension, PIP flexion, DIP extension
pex cavus/pes planus
prior amputation - altered weight bearing causing deformity

23
Q

Neuro exam for DM

A

coordination in walking, balance
DTR
sensation: semmes weinstein 10g monofilament
vibration. sharp/light sensation
proprioception

24
Q

monofilament testing

A

measure for loss of protective sensation
10 sites on foot: toes 1/3/5, 3 points across ball of foot, triangle around heel, dorsal foot proximal to digit 1
4.17/1g: normal sensation
5.07/10g: protective sensation
6,1/75g: loss of protective sensation
insensate: no perception of 75g

25
Q

diabetic neuropathy

A

related to high blood GLC levels
15% of DM pts develop diabetic ulcer over weight bearing surface
40x more likely to have amputation due to poor wound healing

26
Q

DM neuropathy subjective scales include:

A

NSS: neuropathy symptom scale
modified NSS
Michigan neuropathy screening instrument
diabetic neuropathy symptom score (DNS)

27
Q

CV exam for DM

A

vitals, temperature
skin integrity
posture
pitting edema w circumferential measure/figure 8
cap refill
ankle brachial index
color

28
Q

common gait deviations w DM

A

reduced gait speed
reduced ankle mobility
hip circumduction
increased knee flexion
shorter step length/stride
wide stance width
increased double limb support time

29
Q

pt education w DM

A

daily foot inspection
LEAP monthly sensation screening
daily shoe checks
daily warm foot wash and moisturizer
cut toenails straight across
white socks to check for wounds/drainage
proper shoes
no barefoot walking
no hot water/heating pads
followup w Dr on new wounds

30
Q

LEAP: LE amputation prevention

A
  1. annual foot screening
  2. pt edu
  3. daily foot inspection
  4. footwear
  5. manage simple foot problems
31
Q

recommended shoes for diabetic foot wounds

A

min-no risk factors: athletic shoes
some risk factors: large toe box, inserts
minor deformity/single problem: prescription/off shelf shoes
major deformity: Klenzak brace/AFO, custom molded
uncontrolled deformity: crow boot

31
Q

footwear considerations DM

A

offloading abnormal pressure on ulcer
- contact casting
- modified shoes
- wound dressing

32
Q

charcot foot cause and stages of development

A

cause: severe peripheral neuropathy and repeated trauma with loss of protective sensation; abnormal response to repeated injury causing severe destruction of foot architecture
stages:
0: inflammatory, warmth/swelling/pain
1: destruction, weakened ligaments, joint subluxation
2: bone callus, consolidation of fractures
3: fixed deformity and instability

33
Q

benefits of ther ex for DM

A

improved glycemic control
weight reduction/adipose reduction
decreased hyperlipidemia/HTN
slow down CV disease
reduced stress
improved QOL

34
Q

ACSM recommendations for diabetes

A

aerobic: 3-7x week, no more than 2 days w/o activity; mod-vigorous, 150 min/wk, prolonged rhythmic activities
resistance: 3x week nonconsecutive, 50-85% 1RM, 8-10 major m groups, 1-3 sets 10-15 reps
flexibility/balance: 2-3 x wk, light-mod, 10-30 s 2-4x stretch, static/dynamic/stretching/yoga

35
Q

relative contraindications to exercise for DM

A

blood GLC levels:
70-100: snack every hour of exercise w hydration, or more often for intense
100-300: proceed, 1-2+ hours requires more carbs and water
300+ oral meds: try 10-15min exercise and recheck BG, stop if rising, if not continue monitoring
300+ on insulin: check for ketones, stop if positive, continue if not and monitor

36
Q

absolute contraindications to exercise DM

A

BG: <70, hypoglycemia - s/s shaking, dizzy, hunger, headache, pale, jerky, seizure, tingling
hyperglycemia: >300 w ketones, SOB/fruity breath, nausea/vomiting, dry mouth
both emergency

37
Q

diabetic foot exam

A

examine appearance and wounds at all surfaces/under/between toes, toenails
temperature/color
cap refill
monofilament, 3 types in 10 std positions
shoe examination
