Exam 1 Flashcards
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?

Immune mediated joint disease
Immature bone
Cancer
Unstable fractures
Neurological deficits

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.
What is petrissage/kneading?
Skin rolling, wringing or squeezing with moderate pressure.
Benefits: breaks up adhesions/knots, relives muscle spasms, contractions, improved blood flow
What is tapotement?
Rhythmic percussion
Benefits: stimulates skin and provides warmth, parasympathetic NS stimulation for longer periods of time
What is massage friction?
Soft tissue manipulation with thumbs and fingers perpendicular to fibers.
Benefits: Great for joints and tendons, trigger points and to break up scar tissue
What is massage vibration?
Trembling movement with hands, fingers or massage gun
Benefits relax before deeper massage, stimulates soft tissue, relives tensions, decrease stress
What is “normal end feel”?
When the joint has FULL ROM and the range is stopped by the anatomy of the joint
What is soft end feel?
Involving ST such as knee flexion (contact between ST of posterior leg and posterior thigh)
What is “Abnormal end feel”?
When the range of the joint is less or greater than normal. It is PAINFUL or when a structure other than the normal anatomy of the joint stops the motion
What are the grades of joint mobilization?
Grade I: small amplitude at the beginning of the ROM
Grade II: Large amplitude not reaching the end of the ROM
Grade III: Large amplitude reaching the limited ROM
Grade IV: Small amplitude at the end of the limited ROM
Grade V: Small amplitude and high velocity at the end of limited ROM (manipulation or thrust)
What is physiologic mobilization?
Motion that mimics voluntary movements
What is accessory mobilization?
Motion that could NOT be accomplished by voluntary movement
What are firm normal end feels?
Muscular stretch: ex hip flexion with the knee straight
Capsular stretch: Ex: extension of the metacarpophalangeal joints of the fingers
