Here’s a breakdown of the key components and features of such a device:

1. Microcontroller-Based Design: The microcontroller serves as the brain of the device, controlling the different functions and treatment modes. It allows for precise customization of treatment parameters and ensures accurate delivery of electrical stimulation.
2. Diagnostic Muscle Stimulation: This feature involves using electrical impulses to stimulate muscles. It can be used for various purposes, such as muscle strengthening, relaxation, and rehabilitation. Muscle stimulation is commonly employed in physical therapy settings to improve muscle tone and strength.
3. TENS (Transcutaneous Electrical Nerve Stimulation): TENS therapy involves applying low-frequency electrical pulses to the skin’s surface to alleviate pain. It works by blocking pain signals from reaching the brain and promoting the release of endorphins, which are natural pain-relieving chemicals.
4. Soft Keys or Buttons: Soft keys are touch-sensitive buttons that allow users to easily navigate through the device’s settings and modes. These buttons provide an intuitive interface for adjusting treatment parameters, selecting therapy modes, and controlling the device’s functions.
5. Customizable Treatment Parameters: Users can typically adjust settings such as intensity, frequency, pulse duration, and treatment duration. This customization ensures that the therapy can be tailored to an individual’s specific needs and comfort level.
6. Pre-Set Therapy Modes: The device may offer pre-programmed therapy modes that are designed for specific conditions or treatment goals. These modes can simplify the user’s experience by providing preset settings optimized for different scenarios, such as pain relief, muscle relaxation, or rehabilitation.
7. LCD Display: An LCD display provides visual feedback to users, showing selected treatment settings, therapy mode, treatment time, and other relevant information.
8. Electrode Pads: These adhesive pads are placed on the skin at the targeted treatment areas. They serve as the conduits through which the electrical stimulation is delivered to the body. High-quality electrode pads are reusable and designed to be comfortable during use.
9. Safety Features: Modern combo units often come with safety features such as automatic shut-off, lock functions, and adjustable timers to prevent overuse and ensure safe treatment.

      10. Guidance from Healthcare Professionals: Just like any medical device, it’s important to consult with healthcare professionals before using                   a combo unit of this type. They can provide guidance on proper usage, treatment parameters, and whether such a device is suitable for                         your specific health condition.
