drugs delivered by iontophoresis in two ways
locally under electrode
systemically though blood / lymph
which modality do you expect redness
iontrophesis
wound healing evidence level order
HVES
Level b: US, UVC
Level c: laser
pneumatic compression
30-60 mins
pressure below diastolic
3:1 on off ration
NMES stimulates the motor nerve or mm
motor nerve
Critical fusion frequenct
35 hz
is phase charge or shape critical in waveform
phase charge
Effect on /off, where is greater fatigue
1:1
mm grade what should NMES be
Grade 1: 1:5
Grade 2: 1:4
Grade 3: 1:3/2
how to reduce fatiguability in electric stim
mimic voluntary contraction to recruit MU in physiological order
multiple electrodes to reduce MU discharge
decrease frequency
where can you do metal implant
all
where can do you electric implant
none
where is recent fracture , suture or osteoporosis safe
HVPC and TENS
whats monopolar and bi polar
mono - one bigger
bi - two equal areas
is monopolar or bipolar for small mm
mono
monophasic or assym biphasic is bi or mono polar
mono
symmetrical biphasic ci mono or bi polar
bi
difference between small and large electrode
smaller: higher density, less comfortable, higher resistance, specifically , specific
NMES Spasticity mangament
35-65 Hz
gradual rise and fall
1;1
6 days/wk for 1 month
E slim with denervation CONS
repulse growing fibres
disrupt bridge forming
impair recovery
E stim w denervation PROS
accelerates reinnervation environment for growth maintaining elasticity Reverse atrophy Limit skeletal adaptations
to maintain mm force need __ to -_ contractions / day. __ to maintain mm mass
200-800

NMES for quad strength
with exercise , yes it helps
but on functional performance alone - not sure
Knee OA, stroke, COPD has support for NMES?
yes
pain TENS or EMS
no diff
best practice for pressure ulcer with SCI
electric stim w standard wound care
HVES effects
bioelectrical potential galvanotaxis new tissue wound strength edema bflow reoxygenation anti bacterial
optimal schedule for laser for wounds
MTW
benefits of UVC for wounds
antibacterial debridement chemical mediators wound closure wound healing
hydrotherapy for wounds
burns
surgical incisions
pressure ulcers
good for skin temp, below and reduce bacteria
whats MIRE
