2. Outline Introduction Materials and Methods Conclusion and Future work 1/25

3. Introduction Low-cost sensors and wireless systems can now create a constantly vigilant and pervasive monitoring. At home work, in conventional point-of- care environments. Primary care physician offices, outpatient clinics, rehabilitation. 2/25

4. Introduction A large research community (e.g.,the UCLA Wireless Health lnstitute). Vendors of wireless and sensing hardware systems, network service providers. Enterprise data management communities. 3/25

5. Introduction Wearable devices focusing on personal health. Early disease detection are now being prototyped. 4/25

6. Introduction Previously as telehealth. Physicians located in different geographical locations for diagnosis and advice on treatment. 5/25

7. Introduction Signal monitoring, diagnosis, rehabilitation, treatment, generally referred to as wireless healthcare. Telehealth system. Remote areas such as home, schools, nursing home, military camps. Prove the quality of overall healthcare. 6/25

8. Introduction As reported by CNN, back pain affects 80% of Americans at some time in their lives. 31% of all workers compensation dollars are for lower back pain, as reported Herman Miller Inc. 7/25
