1. Biostress feedback instrument: Pressure biofeedback instruments are used to monitor body movements, especially spine movements, during training. They help determine if you are performing certain muscle exercises correctly, preventing pain in different parts of the body and improving core stability. 2. Improve core stability: This device combines a measuring unit connected to a pressure sensor and an inflatable bulb, providing accurate and reliable feedback for joint protection and stabilization training. Dynamic, realtime biofeedback during exercise indicates whether the correct muscles are being targeted and strengthened. 3. Biological pressure biofeedback device: Specifically designed to prevent lower back and neck pain, this tool promotes effective movements while enhancing core strength and stability. 4. Biofeedback device for strengthening the core: With consistent and proper use, it activates deep muscles and improves posture, making it an essential tool for those seeking relief from lower back pain and aiming to enhance their quality of life.
