Lighting Intervention to Improve Sleep
Study Details
Study Description
Brief Summary
50 participants with Parkinson's disease will be recruited to complete actigraphy studies to assess sleep disturbances. For this, participants will wear an Actigraph for seven days. Thirty of these participants with sleep disturbance, will go on to receive a tailored lighting intervention (TLI) to assess the effect on sleep, fatigue, and circadian entrainment via urinary melatonin levels.

Detailed Description
Participants will undergo one week of baseline data collection using the actigraph and light meter and one night of an overnight urine collection. At the completion of the baseline week, the lighting intervention will be installed in the participants home. Participants will be exposed to the lighting intervention for 2 hours each morning after awakening for 4 weeks. During the last week of the lighting, participants will be asked to wear the actigraph and light meter again for 7 days and collect one overnight urine sample. Participants will complete questionnaires before and after the intervention to further assess its effects.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tailored Lighting intervention (TLI) The TLI will be performed for 2 hours each day over a 4-week period. During the last week of the lighting, participants will be asked to wear the actigraph and light meter again for 7 days |
Device: Tailored Lighting Intervention (LIT)
The lighting intervention will provide high circadian stimulation produced by light sources that provide moderate light levels of spectra that are tuned to the sensitivity of the circadian system.
Device: Actigraph
An actigraph is a wrist worn device that measures rest and activity patterns

Outcome Measures
Primary Outcome Measures
- Sleep Duration using Actigraph [at baseline for 7 days]
Sleep duration will be calculated by the Actigraph software. A longer sleep duration would indicate an improvement.
- Sleep Duration using Actigraph [at Week 4 for 7 days]
Sleep duration will be calculated by the Actigraph software. A longer sleep duration would indicate an improvement.
Secondary Outcome Measures
- Sleep Effeciency using Actigraph [at Baseline for 7 days]
Sleep efficiency will be calculated by the Actigraph software. Sleep efficiency refers to the percentage of time a person sleeps, in relation to the amount of time a spent in bed. The percentage is calculated by dividing actual sleep time by time in bed. A higher sleep efficiency indicates better sleep.
- Sleep Effeciency using Actigraph [at Week 4 for 7 days]
Sleep efficiency will be calculated by the Actigraph software. Sleep efficiency refers to the percentage of time a person sleeps, in relation to the amount of time a spent in bed. The percentage is calculated by dividing actual sleep time by time in bed. A higher sleep efficiency indicates better sleep.
- Urine melatonin levels [at Baseline]
Melatonin levels will be assess from overnight urine collection
- Urine melatonin levels [at Week 4]
Melatonin levels will be assess from overnight urine collection
