Interventions
Bright light box
The light box uses a spectrally transparent prism diffuser, which can block ultraviolet rays, but will not affect the quality of the filtered light and will not turn yellow. The distance between the light box and the patient should not exceed 65cm.PD patients are selected for light intervention of different intensities. The experimental group is treated with 10,000 Lux intensity. The treatment time is 1 hour each day from 08:00-11:00 in the morning and 17:00-19:00 in the afternoon lasting for a month. The patient is asked to move under the light source, but should not fall asleep.
Dim Light box
The light box uses a spectrally transparent prism diffuser, which can block ultraviolet rays, but will not affect the quality of the filtered light and will not turn yellow. The distance between the light box and the patient should not exceed 65cm.PD patients are selected for light intervention of different intensities. The control group is treated with 300 Lux intensity. The treatment time is 1 hour each day from 08:00-11:00 in the morning and 17:00-19:00 in the afternoon lasting for a month. The patient is asked to move under the light source, but should not fall asleep.
