In the field of chronic pain management, a quiet revolution is taking place. Traditional treatment methods that rely on painkillers or hormone injections are gradually being replaced by non-invasive and sustainable physical therapies, among which rehabilitation devices centered on dynamic cold and hot circulation technology have become the focus. A 65-year-old patient with periarthritis of the shoulder successfully reduced the Visual Analogue Scale (VAS) pain index from 7 to 3 by using the Cryptherapy Recovery System for 8 consecutive weeks. At the same time, the range of motion of the shoulder joint increased by 40% and the number of hormone injections was reduced to zero. This case reveals the breakthrough potential of non-pharmaceutical treatment in the management of chronic pain.

Periarthritis of the shoulder, as a disease with a high incidence among middle-aged and elderly people, traditional therapies often fall into a "remission - recurrence" cycle. Patients need to take non-steroidal anti-inflammatory drugs for a long time or receive intra-articular hormone injections, but the side effects of the drugs and the injection risks have always been unavoidable problems. The hot and cold compression therapy machine provides a new way to break this predicament through the alternating action mechanism. This device takes precise temperature control technology as its core. In the hot compress mode, it promotes local blood circulation and relaxes muscle spasms. Then, it seamlessly switches to low-temperature therapy to inhibit the release of inflammatory factors, forming a dual closed loop of "repair - pain relief".

Clinical evidence shows that the innovative design of the iceless therapy machine has significantly improved patient compliance. Traditional cold therapy requires frequent replacement of ice packs, while this system achieves a wide range of adjustment from -5℃ to 45℃ through semiconductor temperature control technology, avoiding the risk of frostbite while extending the duration of a single treatment session. Combined with the intelligent compression function, the device can simulate the techniques of a rehabilitation therapist to perform dynamic compression on the shoulder joint, promoting lymphatic return and softening adhered tissues. The above-mentioned 65-year-old patient achieved an abduction Angle recovery from 90° to 150° in the fourth week of treatment, and daily actions such as dressing and combing hair were no longer restricted.

Experts in the field of Body pain relief point out that the core advantage of hot and cold circulation therapy lies in "multi-target intervention". Hot compresses dilate blood vessels and increase oxygen supply, while low temperatures constrict blood vessels and reduce the accumulation of metabolic wastes. This periodic stimulation can reshape the microenvironment of joints and activate the release of endogenous analgesic substances. More importantly, the AI algorithm equipped on the device can adjust the treatment curve based on real-time feedback from patients, avoiding overstimulation or insufficient effect, making family-based rehabilitation possible.

With the popularity of the Cryptherapy Recovery System in rehabilitation centers in Europe and the United States, its clinical data is subverting traditional cognition: 83% of patients with periarthritis of the shoulder can reduce drug dependence within 12 weeks, and the recurrence rate of joint stiffness decreases by 67%. This new paradigm of "physical factor dominance and patient active participation" not only provides a green solution for chronic pain management, but also indicates a profound transformation of the medical model from "passive treatment" to "active rehabilitation". For hundreds of millions of people suffering from chronic pain, the day when they break free from the shackles of medication and regain control of their bodies may no longer be far away.

In this transformation, Chinese technology enterprises are playing an important role. Xiamen Weiyou Intelligent Technology Co., Ltd. has become a benchmark enterprise in the field of global hot and cold cycle therapy with its independently developed hot and cold compression therapy machine. The company has been deeply engaged in the field of rehabilitation medicine for over a decade. Its products include air wave pressure therapy devices, intelligent rehabilitation robots and other series. Its ice-free refrigeration technology and dynamic pressurization algorithm have obtained multiple international patents. At present, Weiyou's equipment has entered medical institutions in over 30 countries around the world, providing non-pharmaceutical treatment options for millions of patients with chronic pain and redefining the future landscape of pain management.
