A: Generally speaking, many families will choose a simple and affordable intermediate frequency therapeutic instrument for their own use, while rehabilitation departments and physiotherapy halls will choose professional equipment such as medical-grade intermediate frequency therapeutic instrument, intermediate frequency interference wave and transcutaneous electrical nerve stimulator.
First of all, let's talk about the difference in naming between products. In the product naming sequence, the household intermediate frequency series starts with ZP or QL/ZP, and the low frequency is QL/*-I. According to the usage scenarios, intermediate frequency products are divided into two categories: household and medical. Customers often ask me: What is the difference between domestic and medical IF therapeutic instruments? This question is in the last article "The difference between words, big difference! The difference between home/medical IF therapeutic instrument is mentioned in the article, and I would like to add one more point here: the home form is smaller, while the medical form is larger.
Suppose it is QL/N-IV. The output waveform of the electrotherapy instrument is bidirectional asymmetric square wave, and the modulation waveform is square wave, which is mainly aimed at the auxiliary treatment of partial/complete nerve inactivation symptoms. The therapist, Deputy Chief Physician of the Department of Rehabilitation Medicine of Run Run Run Shaw Hospital, mentioned in the research paper "Observation on the therapeutic effect of neuromuscular electrical stimulation combined with rehabilitation training on dysphagia in patients with ischemic stroke" that neuromuscular electrical stimulation therapy can effectively help patients with ischemic stroke recover at 80Hz.
The treatment square wave type of QL/T-III is bidirectional asymmetric square wave like QL/N-IV, and the most obvious difference from IV is the output pulse frequency. The frequency of III is between 0.5Hz ~ 5hz ~ 5hz, and the frequency of IV is between 2hz ~ 160Hz, which means that the low frequency of III can directly trigger muscle movement. And the IV high frequency is closer to the intermediate frequency. Because IVA outputs two sets of square waves at the same time, it does not represent a fixed frequency. IVA simultaneously outputs two groups of square waves with the width of (0. 1 ~ 0.5 ms) and the frequency of (0.66 ~ 1.0 Hz, with the time sequence of 0. 1~0.3s, which stimulates spasticity and its antagonistic muscles to contract alternately. QL/H-IVA spastic muscle low-frequency therapeutic instrument is mainly used for the auxiliary treatment of this kind of spastic paralysis. Lilac Garden, a famous medical authority website in China, defines the application scope of spastic muscle low-frequency therapeutic instrument as: children with cerebral palsy, spastic paralysis caused by spinal cord injury and patients with increased muscle tension caused by other diseases. One of the direct functions of QL/H-IVA spasmodic muscle low-frequency therapeutic instrument is to excite neuromuscular tissue, which is usually used to cooperate with drugs to promote the repair of human motor neurons.
Ma Xiao Ting, who lives in Sweet Potato Town, Pu 'an County, Southwest Guizhou Province, unfortunately suffered from spastic paralysis at the age of 6. Her mother carried her on her back for 12 years. In 7 years, she carried her daughter on her way to school for 5,600 kilometers. We are very sorry that we didn't meet her before 12 years ago. Maybe meeting her will make her life a different color.
