H - Wave - Coggle Diagram
H - Wave
Is this treatment fatiguing? no- does not trigger an activation of the motor nerves of the large white muscle fibres
-
How would you discuss the effects of H wave on overlying oedema over the gluteal medius bilaterally? -directly stimulates the small smooth muscle fibers within the lymphatic vessels ultimately leading to fluid shifts and reduced edema
-
Why would this be beneficial at targeting this oedema in comparison to other modalities.. Remember when choosing your modality, you need to discuss why you have not chosen the others.
How on a cellular level will H wave reduce/ aid removal of this oedema and overall enhance muscle function...
Settings
-
Pain relief:
- 60hz
- Minimum 10 mins
- Turn intensity up to effect.
A combination of the two settings may be used depending on the complexity of the condition. eg. pain setting for 10 mins followed by the therapy setting for 20 mins.
Frequency: - Induction = 3x week one, 2x week two (resolved?).
- Transition phase = 1x weekly if necessary.
- Maintenance = on regular maintenance visits (eg. 4-6 weekly).
Uses: Due to low pain, deep application & benefit on lymph system..
-
Manufacturer claims:
- Chronic pain
- Acute pain
- Post surgery
- Soft tissue / inflammation
- Muscle spasm
- Decreased ROM
- Muscle Atrophy
- Compromised circulation
- Nerve damage
Research limited/ mostly human, however anecdotally effective..
High frequency (60Hz)
- Not appreciated by all horses
- Produces short term deep analgesia / local anaesthesia
-Pain gate = Shuts down transmission of pain signals.
- Stimulates endorphins = endogenous pain reducing chemical - inhibits substance P - pain neurotransmitter.
- If tolerated, can be used to provide pain relief prior to using lower frequency for therapeutic use or before manual therapies.
Low frequency (2Hz)
- Creates visible muscular contractions
- Increase venous return of blood & stimulates lymphatic drainage.
- Increased blood & lymph flow = removal of pain producing chemicals, thus reducing pain & allows lymphatic system to work more efficiently- stimulating healing.
- Oedema:
- byproduct of cellular metabolism, pools in interstitial spaces.
- H wave directly stimulates the smooth muscle fibers within the lymphatic vessels ultimately leading to fluid shifts and reduced edema
What is it?
- Transcutaneous electrotherapy which stimulates a contraction within the muscle fibres.
- H Wave uses a bipolar exponential decaying waveform that enables greater and deeper penetration at a lower current. Supposed to mimic the body's natural nerve signal Hoffman reflex.
- Lower frequency current = non fatiguing (doesn't activate motor nerves of white muscle fibres) and more comfortable/ less painful (doesn't stim sensory delta and C pain nerve fibres) & therefore more accepted than Tens.
- Vasodilation: Stimulates release of NO which relaxes smooth muscle cells lining blood vessels.
- Also less resistance @ skin/electrode interface = stronger current used more comfortably.
- Multiple frequencies can be administered at same time = increasing therapeutic function & reducing tx time.
- Manufacturer claims that it combines both neuro & muscular stimulation- unlike other devices.
Contra's:
- Sepsis
- Heart problems (as with all electrical stim)
- Pregnancy
- Avoid brain & organs
- Animals subject to seizures
- Over carotid artery
- Tumours
Global effects:
- Reduced pain - especially chronic
- Restored functionality- quicker return to work
- Removes oedema
- Accelerates toxin removal
- Increased range of motion
- Quicker healing / recovery
