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

Summary

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.

Conditions

• Frozen Shoulder

Interventions

OTHER

Rehabilitation exercise

Rehabilitation exercise use the methods that suggested by previous studies including finger wall climbing, pendulum exercise, and arms lifting.

DEVICE

joint mobilization device treatment

The joint mobilization treatment used the mobilization device that developed in this research.It is a device developed by using the design of the vibration force generated by the vibration mechanism and the technologies to simulate the mobilization of the shoulder joint.When the subject uses the device, first sit on a seat that can be adjusted according to the user's body shape and buckle the shoulder fixation device. Then use the specially designed shoulder movement setting mechanism of the device to set the user's shoulder movement and movement angle.The next step is to set the direction and magnitude of the vibration force applied by the device to the shoulder joint in accordance with the joint mobilization technique (posterior, anterior, and inferior) that the therapist or user intends to perform to achieve the effect of simulating joint mobilization and increasing joint mobility.

DEVICE

laser acupuncture device treatment

The laser acupuncture treatment use the laser acupuncture device that developed in this research. A gallium-aluminium-arsenide (GaAlAs, infrared laser) continuous wave diode laser device with a wavelength of 850nm (invisible), a power output of 100 mW, and a spot area of 0.07cm2 was used for laser acupuncture.When performing laser acupuncture treatment, the laser emitted by the device is irradiated on the selected acupuncture points .The acupuncture points (GB 21, LI 4, LI 11, LI 14, LI15, LI 16, SI 9, SI 10, SI 11, TE 14, and TE 15) were determined according to the literature regarding acupuncture application in shoulder pain based on traditional chinese acupuncture.
