Q: What is the difference between low-frequency and intermediate-frequency therapeutic instrument?
A: Generally speaking, many families for their own use will choose the simple operation, affordable home intermediate frequency therapeutic instrument, while the rehabilitation department, physical therapy hall will choose the medical grade intermediate frequency therapeutic instrument, intermediate frequency interference wave and transcutaneous electrical nerve stimulation instrument and other professional equipment.
First of all, let's talk about the difference in naming between products. In the product naming sequence, household IF series is to ZP or QL/ZP beginning, low frequency is QL/*-I. IF products according to the use of the scene is divided into two categories of household and medical, often customers ask me: IF therapeutic instrument for home use and medical what is the difference between it? This issue in the previous issue of the article "the difference between the word, the difference is great! The difference between home / medical intermediate frequency therapeutic instrument" has been mentioned, and here to add a little more: the form of the home is more compact, while the medical form is larger.
Let's say QL/N-IV, the output waveform of this electrotherapy device is a bi-directional asymmetric square wave, the modulation waveform is a square wave, mainly for the partial/complete nerve deactivation symptoms of auxiliary treatment. The deputy chief therapist of the Department of Rehabilitation Medicine of Shaw Hospital affiliated to Zhejiang University School of Medicine mentioned in the research paper "Observation on the efficacy of neuromuscular electrical stimulation combined with rehabilitation training in the treatment of dysphagia in the pharyngeal phase of ischemic stroke patients" that neuromuscular electrical stimulation therapy at 80Hz can effectively help patients with ischemic stroke to recover.
The QL/T-III is a bi-directional asymmetric square wave like the QL/N-IV, but the most obvious difference between the IV and QL/T-III is in the frequency of the output pulses, which ranges from 0.5hz to 5hz in the case of the III, and from 2hz to 160hz in the case of the IV. This means that the III can achieve a low frequency that is sufficiently low to trigger a muscle movement, while the IV is closer to the middle frequency. IVA does not have a fixed frequency because it outputs two sets of square waves at the same time. IVA outputs two sets of square waves with wave width (0.1~0.5ms) and frequency (0.66~1Hz) at the same time, with a time sequence of 0.1~0.3s, stimulating spasticity and its antagonist muscles to contract alternately. ql/h-IVA spasticity low-frequency therapeutic instrument is mainly aimed at this kind of spasticity paralysis for auxiliary
Ma Xiaoting, who lives in Digua Town, Pu'an County, Qianxinan Prefecture, was unfortunately stricken with spastic paralysis at the age of 6. Her mother carried her on her back for 12 years, from elementary school to university, and during the 7 years she carried her daughter on her back for 5,600 kilometers on her way to school, and we regretted that we didn't meet with her 12 years ago, and perhaps met, and was able to make her life have a different color.
