What are the differences between NMES and TENS
NMES is for Muscle Weakness targeting MOSTLY Type I (slow twitch cardio) muscles fibers after initial Type II (fast twitch strength) fibers to create tetanic contractions of selected muscle groups WITHOUT PAIN
TENS is for Pain relief and uses hyper stimulation of nociception (pain gate theory) to release enkephalins (sensory level) and/or endorphins (motor level)
How can Non-noxious stimulation reduce pain?
Activates “closed” gate control mechanisms to reduce pain
Ex: soothing, rubbing, ice/heat, TENS
What are the indications for RICE?
Acute inflammatory response day 1 to 5
What are the indications for TENS?
Pain relief; acute/chronic pain
What are the indications for NMES?
Treat muscular weakness, disuse atrophy, early post-op edema
What are indications for ESWT?
Great for horses; OA, tendon/ligament injuries, nonunion or delayed healing fractures
What are indications for Therapeutic US?
Breakdown of scar tissue, increase elasticity of muscles, aid in healing, increase circulation, reduction of pain/spasms
What are indications for PEMF?
Wound healing, pain management, inflammation, post surgical healing, OA
What are the SENSORY settings for TENS?
Pulse duration: 2-50 pulses/usec
Frequency: 50-150 Hz (pulse/sec)
Duration: 20-30 min, no cycle time
Amplitude: comfortable tingling for the patient
GOAL: Produce enkephalin release
What are the MOTOR settings for TENS?
Pulse Duration: >150 pulses/usec
Frequency: 2-4 Hz (pulses/sec)
Duration: 30-45 minutes, no cycle time
Amplitude: visible muscle contraction
Goal: Endorphin release (long half life)
What are the settings for NMES?
Waveform: symmetrical or biphasic
Pulse duration: 100-300 usec
Frequency: 30-50 Hz (pulse/sec)
On/off time; strengthening: 1:3-1:5, Endurance: 1:1-1:2
Electrode size: larger more comfortable but appropriate for muscle groups you are trying to isolate
Treatment time: 15-20 min
Goal: tetanic contractions of selected muscle group WITHOUT PAIN
What are the settings for Therapeutic U/S?
Frequency:
1 MHz: longer wavelength penetrate 2-5 cm requires higher intensities
3.3 MHz wavelength penetrates 0.5-2cm requires lower intensities
Pulsed vs. continuous waves
What are contraindications for ESWT?
Infectious arthritis
Immune mediated joint disease
Immature bone
Cancer
Unstable fractures
Neurological deficits
Neural tissue
Lung tissue
What are contraindications for Therapeutic U/S?
Neoplasia
Areas of hemorrhage
Immediate injury
Eyes
Gonads
Gravid uterus
Ischemic tissue/devitalized tissue
Spinal cord post laminectomy
Phase two incision sites (wait at least 14 days)
What are contraindications for PEMF?
Tumors
Pregnant uterus
Open growth plates
Over the heart
Electro medical devices
Acute/active inflammation
Eyes
What are the healing qualities of PEMF?
Electrical currents—>increase Ca2+ concentrations—>creates short burst of NO prodxn—>vasodilation, osteoblasts proliferation, immune response, down regulation of Cox2, cellular proliferation, chondrocyte proliferation, reduction of cytokines
What are the healing qualites of therapeutic U/S?
Increase metabolic rate
Increase enzyme activity
Increase circulation
Increase extensibility in tissues
Decrease pain
What are the healing qualities of ESWT?
Reducing inflammation
Short-term analgesia
Increase neovascularization
Increase osteoblast activity
Realign fibers for more parallel healing
What are the healing qualities of NMES?
Selective contraction of a muscle group
Less strong than voluntary contraction
Recruitment of type II muscle fibers (strength fast twitch)
MOSTLY affects Type I muscle fibers (slow twitch cardio)
What are the healing qualities of TENS?
Stimulation of the A-Beta fibers via the TENS blocks smaller fiber activity.
Hyper stimulation of nociceptors (pain gate theory)
What are the settings for PEMF?
Acute/post op: every 2 hours self cycle option
Chronic: 2-3x/ week
Which manual therapies require specialized training?
Chiropractic work (joint mobilization)
What is massage?
The rubbing and kneading of muscles and joints of the body with the hands, especially to relive tension or pain; Tui Na in Vet med
What is effleurage?
Rhythmic stroking-mild/moderate pressure parallel with muscle fibers. Increase pressure with the larger areas, decrease with the smaller areas.
