Invention of Portable Laser Acupuncture and Joint Mobilization Device on Frozen Shoulder and Therapeutic Effects

Invention of Portable Laser Acupuncture and Joint Mobilization Device on Frozen Shoulder and Therapeutic Effects

the volunteers with frozen shoulder will be recruited to this experiment and use devices under a designed experimental procedure. After subjects use device , R&D team will collect subject feedback, efficacy assessments, and various device data. This step will not only help investigators to improve and refine the device but also find the best operating mode and using standard of the device to help the frozen shoulder patients.

Subjects in this study will also enter a designed course of treatment. All patients will be distributed equally and randomly to three groups (control , mobilization device, laser acupuncture plus mobilization device) to receive treatment. All groups receive three therapy sessions per week for 8 consecutive weeks. At last, investigators will compare the differences between the three groups to understand the effect of portable laser acupuncture and joint mobilization device on frozen shoulder.

Adhesive capsulitis (also known as frozen shoulder) is a painful and disabling disorder of unclear cause in the shoulder capsule. There are many ways to treat frozen shoulders. Laser acupuncture and joint mobilization are both ways to treat frozen shoulders. According to the literature, laser acupuncture has the effect of pain control for frozen shoulder and joint mobilization can increase the patient's shoulder range of motion. As a creative inspiration, the R&D team uses application and principle of these treatment to design the device. After cooperation and effort, the R&D team developed two devices that are 「portable laser Acupuncture device for frozen shoulder」and「the joint mobilization simulation device」. During the development of two devices, collecting various usage data and user's feelings, feedback and clinical effects are very important. So, R&D team will use this research project to help device development. This project will recruit volunteers as objects for device development and advancement.
