BIOPHYSICAL
functional mobility assessment: take if the modality would improve the thing that is limiting mobility (pain, motor control, edema, etc)
before modalities: pain assessment, ROM, strength, skin (metal implants)/sensation assessment
modalities: US/ultrasound, NMES, ESTIM: TENS/IFC, Biofeedback, HVPC, EMG/electromyography, ESTR, EMR
target pain:
US (chronic and acute)
ESTIM (acute: sensory analgesia, painful procedure, noxious stimulus/chronic: endogenous opiate, noxious stimulus, sensory analgesia)
improve ROM:
from pain: US, ESTIM
from tightness: US, NMES
provide heat:
US: with head or continuous
indications:
US:
continuous: pain from chronic inflammation, decreased ROM, scar remodeling
pulsed: pain from acute inflammation, edema
ESTIM:
acute/chronic pain
NMES:
weakness, hypertonicity/spasticity, edema, orthotic substitution (decreased motor control), endurance
stroke population weakness, CVA
shoulder subluxation
Biofeedback:
decreased motor control
ESTR:
wounds (pressure/decubitus, venous insufficiency, arterial insufficiency, diabetes mellitus)
EMR:
muscle guarding, tightness, pain, acute/chronic conditions, inflammation, etc.
contraindications:
US:
infection, hemorrhage, DVT, medical devices, abscess, cancer, psoriasis
relative: lack of sensation, PVD, growth plates, pregnancy, cognition, open wound, deep metal/cement
ESTIM:
absolute: malignancy, pacemaker, lacking sensation
relative: epilepsy, impaired sensation, cardiac disease
NMES:
absolute: demand pacemaker, pregnancy 3rd
relative: malignancy, impaired sensation, superficial metal, cardiac problems, cog., skin irritation
Biofeedback:
open wounds
relative: impaired mental status, skin irritation
ESTR:
metal
EMR:
metal
sensation
US: literally nothing unless to intense
ESTIM:
sensory analgesia: strong tingling, no twitching
painful procedure: non-rhythmic contraction, strong tingling
endogenous opiate: muscle twitch
noxious stimulus: highest toleration
NMES:
muscle contractions, sensory input, stabilization, correct timing of contraction, strengthen
limitation: discomfort
settings
US:
continuous: 10 min
pulsed: 5 min (used for healing)
1 (deeper) or 3MHz
ESTIM:
sensory analgesia: 75-150pps, 60-100 microseconds, tx time, surrounding
painful procedure: 150+pps, 150+ microseconds, 15-30min, dermatome lvl
endogenous opiate: 1-5pps, 200-300 microseconds, 30-45 min, motor points
noxious stimulus: 1-4 pps, 1 msec, 30 sec, on point
IFC:
sweep (prevent/decrease sensory habituation), beat frequency, vector scan
NMES:
pps: higher is more comfortable and less fatiguing, mA: 70% strength, 50% endurance (guestimate it bud), microseconds: higher is more stimulation, time: intervention activity, on/off: 5x off for power, 3x off for endurance, or just what’s needed, waveform: asymmetrical for small muscles, IFC: 2 agon. and 2 antag.
more fatiguing: polyphasic waveform, shorter off time, higher frequency
won’t affect strength: ramp up/down
small muscles: 150-200 microseconds
Russian current: alternating current of 2,500 Hz, burst-modulated at 50 bursts per second using 10-msec burst duration
interferential current: crossing electrical fields, third field is produced that effects deeper tissue in a larger tx area
