Abstract :

Vibration therapy has gained increasing recognition as an effective modality for promoting musculoskeletal health, rehabilitation, and pain management. In this study, we introduce a novel vibration massager equipped with a frequency-controlled actuation system and a dual-peak cam mechanism. The design enables precise modulation of vibration frequency within the therapeutic range of 75-225 Hz while minimizing motor speed requirements, thereby improving energy efficiency and system durability. Frequency stabilization is achieved through a reflective optical sensor in combination with a PID controller, ensuring consistent vibratory output under varying operational conditions. The modular nature of the device further allows for versatile deployment, whether as a handheld tool, fixed to the body via a fixture, or integrated with robotic arms in clinical environments. By combining engineering innovations with adaptability in use, this work provides a foundation for advancing vibration-based therapeutic technologies and opens new pathways for integration in clinical practice.
