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
