4. H-Wave Electrotherapy
In our opinion, the H-Wave machine by Electronic Waveform Lab, Inc., is one of the iconic electrotherapy devices on the market today (Table 1). It has become a staple in our core service provisions and is one of the few devices that all our clinics are encouraged to have on site. I do not sell, assist in selling, advertise, or in any way endorse this or any product for financial or other gains. I have always distanced myself from the products tested to avoid any conflict of interest.
This technology is popular because of its simplicity, ease of use, and patient response. The mechanism of action is rather unique in that H wave stimulation targets the lymphatic system, and flow dynamics in particular. Research supports one of the positive effects to be an enhanced lymphatic flow allowing for improved cellular waste clearance and increased tissue oxygenation. The H wave pathophysiological model represents somewhat of a paradigm shift in the field of electrotherapy.
Strength of Treatment
Most patients who undergo H wave treatment will have an opinion on whether it helps with their problem or not. It is rare to have a non-committal treatment response—the bane of treatment responses. Our practices have had good success at treating a wide range of conditions, including tendinopathies, arthropathy, and myofascial pain, with virtually no adverse effects being reported by patients. Some patients insist on having a home unit, which can sometimes be arranged, depending on the insurance carrier.
Ease of Treatment
The device is very user friendly and does not require an extensive training in-service for providers. The user simply chooses from 2 frequency settings and then adjusts for intensity based on patient comfort. This treatment is unassisted and does not require the provider to administer the treatment, other than simply setting a patient up and turning the machine on.
Patient acceptance typically is above average, especially as treatment success builds over time. The H-Wave is a powerful adjunctive treatment, and although I cannot attest to the precision of the postulated mechanism of action (for any device), our empirical observations confirm the positive effects patients experience with lymphedema, acute swelling. and pain.
