The world is facing rapid population aging, the health needs of the elderly are complex, and their physical capabilities are degraded, and increased the possibility of having one or more chronic conditions. In 1900 to 2000, there were 7,600 million people in the United States, aged 65 and above age increased to 4.1% up to 12.6%, by 2050 is expected to increase 20.3%.In Taiwan, the elderly population have 83.5% is health and sub-health, in order to allow them to perform activities of daily living independently, in particular, need to pay attention to the diverse needs of the elderly, Assist the elderly to increase self-care skills, reduce disability is a very important issue.
From literature review of LED phototherapy can effectively improve symptoms in the elderly, such as hair loss, dermatitis, rotator tendonitis, epicondylitis of the tibia, wound healing, back pain, patellofemoral pain, spinal neuropathy, chronic pain relief, insomnia and depression. Comprehensive Phototherapy and Traditional Chinese medicine(TCM) perspective, LED phototherapy is the use of physical light energy stimulation and temperature to improve the body's microcirculation and meridian dredge, Enhance the body's energy of the health and sub-health elderly, increasing physical activity perform daily functions. Taiwanese Elderly to take self-care by the dilemmas of the many aspects. There are 21.52% physical health problems, affecting work or daily activities are limited; there are 35.12% physical or emotional health problems affecting social activities; there are 13.01% incapable perform activities of daily living. The aim of this study was to explore the effectiveness of LED phototherapy on physiological symptoms among elderly in long-term care institutions in Taiwan. To examine the effects of physiological symptoms, such as mental state, muscle bone system, metabolism, autonomic balance and other meridian energy tests, it is expected to improve the body energy of healthy and sub-healthy elderly to increasing physical activity perform daily functions.

Chong-En Group Long-term Care Center for the Elderly
Kaohsiung City, Taiwan
Pittsburgh Sleep Quality Index/PSQI
Insomnia was measured by the Pittsburgh Sleep Quality Index (PSQI), Global PSQI \>5 score，good sleep；Global PSQI ≦5 score，poor sleep。
Time frame: Change before, through intervention completion (average 6 weeks).
Brief Fatigue Inventory-Taiwanese (BFI-T)
Fatigue was measured by the Brief Fatigue Inventory-Taiwanese (BFI-T), BFI-T=0 score，no fatigue；1\~3 score，A little tired (not tired most of the time)；4\~6 score，Ordinary tired, tolerable (about half the time to feel tired)；7\~9 score，very tired (most of the time feel tired)；10 score，most tired (I feel tired all the time)。
Time frame: Change before, through intervention completion (average 6 weeks).
Cold Limbs
Cold Limbs was measured by the Yes / No Questionnaire elderly subjective feeling, "Yes" in the questionnaire means cold limbs；"No" in the questionnaire means no cold limbs。
Time frame: Change before, through intervention completion (average 6 weeks).
Braden-Pressure ulcer risk factor assessment scale
Pressure ulcer was measured by the Braden-Pressure ulcer risk factor assessment scale, ≧16 score，Low-risk；12-15 score，Moderate risk；≦11 score，High-risk。
Time frame: Change before, through intervention completion (average 6 weeks).
Meridian Energy
Meridian energy was examined by using the Meridian Energy Analysis Device(M.E.A.D.), Parameters and normal values：Mental health status：0.78-1.09；Musculoskeletal status：0.88-1.14；Metabolism status：0.82-1.24；Autonomic nervous system status：1.0-1.5；Overall energy：28-64。
Time frame: Measured 1 week before and 1, 4, 6 weeks after intervention
HRV
Autonomic nervous system activity was examined by using the Heart Rate Variability (HRV), Parameters and normal values：Low Frequency power(LF)：0.04\~0.15 Hz；High Frequency power(HF)：0.15\~-0.4 Hz；Standard deviation(SD)：All normal to normal intervals, the larger the SD, the greater the HRV；mean Heart Rate；LF/HF ratio。
Time frame: Measured 1 week before and 1, 4, 6 weeks after intervention
Body Temperature
Cold Limbs was measured by the body temperature (BT), Ear temperature measurement normal BT 36 \~ 37.5。
Time frame: Measured 1 week before and 1, 4, 6 weeks after intervention
