In the fast-paced modern workplace and academic life, white-collar workers, students and other people who sit for long periods of time work or study at desks, and stiffness and soreness in the shoulders and neck have become common problems. Maintaining the same posture for a long time causes continuous tension in the shoulder and neck muscles and poor blood circulation. This not only affects work efficiency and learning state but may also trigger a series of health problems. Against this backdrop, the four-channel physiotherapy device, with its unique functions and technologies, has brought new hope for shoulder and neck relaxation to people who sit for long periods.

Technical principle: TENS and EMS work in synergy
The core technology of the four-channel physiotherapy device lies in the perfect combination of TENS (transcutaneous Electrical nerve Stimulation) and EMS (muscle electrical stimulation). The TENS unit for shoulder pain and TENS unit for neck pain modes input specific low-frequency pulsed currents into the human body through the skin, acting on sensory fibers and blocking the transmission of pain messages to the brain, thereby effectively alleviating shoulder and neck pain. This non-pharmaceutical pain relief method avoids the possible side effects of drugs and provides a safe and convenient treatment option for patients with shoulder and neck pain.

The EMS massager mode simulates the brain's bioelectrical signals, "deceiving" the muscle nerves and causing the muscles to contract autonomously. This "passive" fitness method does not impose additional burdens on the joints, but it can enhance muscle endurance and support, and relieve the pressure on the joints and bones. For sedentary people, EMS technology can help them exercise their shoulder and neck muscles, improve muscle condition, and fundamentally alleviate shoulder and neck stiffness.

Scenario-based usage guide: Relieve shoulder and neck discomfort anytime and anywhere
（1）Office scene: The "Invisible Physiotherapist" at the workstation
For white-collar workers, it would be great if they could easily relieve stiffness in their shoulders and necks in the office. The portable design of the four-channel physiotherapy device enables it to be placed at the workstation for use at any time. During breaks at work, such as before the lunch break or after completing an important task, simply wear the physiotherapy device on the shoulder and neck area and select the appropriate mode and intensity. For example, you can first use the TENS mode to relieve pain, and then switch to the EMS mode for muscle training. This intermittent usage method will not affect normal work, but can effectively relieve shoulder and neck fatigue, allowing white-collar workers to maintain a comfortable state even in their busy work.

（2）Learning scene: The "Relaxation companion" beside the desk
The student group also faces shoulder and neck problems caused by prolonged sitting. During the learning process, reading or doing homework with the head down for a long time keeps the muscles in the shoulders and neck in a tense state for a long time. The four-way physiotherapy device can serve as a "relaxation companion" for students during their studies. During the break between classes or after completing some study tasks, use the physiotherapy device for a brief shoulder and neck massage. You can choose the gentle TENS mode to relax tense muscles and relieve pain. Or use the EMS mode to enhance the strength of the shoulder and neck muscles and prevent muscle strain. This can not only improve the learning efficiency, but also protect students' physical health.

（3）Home Scene: The "Health Guardian" in the family
After work or school, sedentary people can enjoy longer periods of physical therapy at home. The dual-zone large-area hot compress function of the four-channel physiotherapy device can bring a more even sense of warmth, as if a warm current is surrounding the neck, promoting blood circulation and further relieving muscle tension. Before going to bed, using a physiotherapy device, choosing the relaxation mode, gentle massage and comfortable hot compress can help the body relax, relieve the fatigue of the day and improve the quality of sleep. For sedentary people with poor sleep quality, this is undoubtedly a good way to improve their sleep.

（4）Post-exercise scene: The "Recovery Magic Tool" for sports enthusiasts
Even sedentary people do some exercise occasionally to keep fit. After exercising, the muscles in the shoulders and neck may experience soreness and fatigue. The EMS function of the four-channel physiotherapy device can help sports enthusiasts recover quickly. By simulating the brain's bioelectrical signals, it enables muscles to contract voluntarily, promotes blood circulation, accelerates lactic acid metabolism, and relieves muscle soreness. Using a physiotherapy device for a massage after exercising can help sports enthusiasts regain their energy more quickly and get back to the next workout.

User witness: The real effect is obvious to all
Many users have personally experienced the remarkable effects brought by the four-channel physiotherapy device. A white-collar worker who has been working in an office for a long time said, "Before, my shoulders and neck would be extremely sore after work every day. After using the four-channel physiotherapy device for a period of time, the stiffness in my shoulders and neck improved significantly, and my work efficiency also increased." Another student gave feedback: "When using the physiotherapy device while studying, I feel much more relaxed in my shoulders and neck, and my attention is also more concentrated." These real user testimonies fully demonstrate the effectiveness of the four-channel physiotherapy device in alleviating shoulder and neck stiffness in the office.

Reason for choice: Technology integration, effect guarantee
The four-way physiotherapy device has become a blessing for sedentary people not only because of its advanced technology, but also because of its technological integration and effect guarantee. In terms of technology integration, 3D pulse simulation human hand massage has a precision that surpasses traditional physical therapy. It can penetrate deep into the muscle layer and effectively relieve shoulder and neck pain. In terms of scene adaptation, the workstation first aid technique and deep conditioning are seamlessly integrated into workplace life, allowing people who sit for long periods to receive shoulder and neck care anytime and anywhere. In terms of effect guarantee, 90% of the users experienced a 70% reduction in shoulder and neck pain within 7 days and a 50% improvement in posture straightness within 14 days. These data fully demonstrate its excellent results.

In this fast-paced era, sedentary people no longer have to worry about stiff shoulders and necks. The four-channel physiotherapy device, with its advanced technology, convenient usage and remarkable effects, has become an ideal choice for people who sit for long periods to relieve shoulder and neck discomfort. Let's embrace the four-way physiotherapy device together, bid farewell to stiff shoulders and necks in the office, and enjoy a healthy and comfortable life.
