Study summary

Objective To determine the optimum treatment protocol of auriculotherapy (AT) on the improvement of sleep conditions and quality of life on the elders with insomnia.

Research hypothesis The use of combined LAT plus MAT is more effective than MAT/LAT alone on the improvement of sleep conditions and quality of life in the elderly with insomnia.

Design and subjects This is a 3-arm double-blinded randomised trial. Subjects aged ≥65 and exhibit poor sleep conditions are recruited.

Interventions Group 1: Subjects will receive a deactivated laser treatment followed by MAT. Group 2: Subjects will receive LAT and placebo MAT. Group 3: Subjects will receive a combined approach (LAT plus MAT).

The treatment will be delivered 3 times/week, with a 6-week treatment period, on seven specific auricular points.

Main outcome measures Sleep conditions and quality of life will be evaluated at baseline; end of 6-week treatment; and at 6-week, 12-week, and 6-month follow-up periods.

Data analysis Descriptive statistics, chi-square analysis, ANOVA, paired t-test, and mixed effect modeling will be conducted as appropriate.

Expected results This study would advance our knowledge the optimum treatment protocol of AT in the improvement of the sleep conditions of the elderly population.

Study arms

  • Active comparator
    Treatment arm 1

    To achieve a blinding and placebo effect of the subject, the laser device will be switched to "power off" mode (i.e. deactivated laser) for acupoint "stimulation" before the application of MAT. The subjects will be asked to wear a pair of laser protective goggles so as to "blind" them during treatment.

    Device: magneto-auriculotherapy (MAT)

  • Active comparator
    Treatment arm 2

    Subjects will receive LAT. A laser device (Pointer Pulse™) will be used in this study.

    Device: Laser auriculotherapy (LAT)

  • Experimental
    Treatment arm 3

    Subjects will receive a combined approach that includes the use of LAT plus MAT. LAT will be administered prior to MAT application on the selected auricular points, and the procedures used will be similar to the procedures described for Group 1 and Group 2.

    Device: magneto-auriculotherapy (MAT) · Device: Laser auriculotherapy (LAT)

Interventions

  • Devicemagneto-auriculotherapy (MAT)

    Subjects will then receive MAT. The magnetic pellets will have \~200 gauss/pellet magnetic flux densities on average, with a diameter of 1.76 mm.The experimental object will be applied to the seven selected acupoints as detected by an acupoint detector. Only one ear will receive treatment at a time, and the pellets will remain in situ for two days before the next change.

  • DeviceLaser auriculotherapy (LAT)

    A laser device (Pointer Pulse™)15 will be used in this study. This device has a wavelength of 650 nm, an average output power of 2.5 mW, an energy density of 1 minute with 0.54 J/cm,2 and a pulse of 10 Hz, which is a common acceptable dosage for clinical use. 16, 17 This application is a low-energy laser therapy (LLLT), in which the energy level emitted from the device is approximately comparable to a teaching pointer. A 1-minute treatment using the continuous mode of the device will be directly applied to the selected acupoints. Laser protective goggles will be provided to the subjects and the researcher for eyes protection

What researchers measure

Primary outcomes

  1. Pittsburgh Sleep Quality Index (PSQI)

    for collecting data related to the sleep patterns of the subjects. The total score ranges from 0 to 21, with a score greater than five indicating poor sleep quality. Chong and Cheung19 have validated the Cantonese-PSQI and have reported a high internal consistency of 0.75.

    Time frame: up to 6-month follow up

Secondary outcomes

  1. Sleep latency

    Actiwatch 2 Device with 0.025G ultra-high sensitivity will be used for data collection. Sleep parameters, including sleep latency, waking after sleep onset, total sleep time, and sleep efficiency are identified. Participants have to wear the device for 7 consecutive days, 24 hours a day, for each timepoint measurements on the wrist of the non-dominant hand to determine the overall sleep conditions within a certain period. Removal (if any) of the actiwatch should be recorded in a logbook. Sleep latency refers to the length of time it takes from lying down for the night until sleep onset.

    Time frame: up to 6-month follow up

  2. Wake after sleep onset

    Actiwatch 2 Device with 0.025G ultra-high sensitivity will be used for data collection. Sleep parameters, including sleep latency, waking after sleep onset, total sleep time, and sleep efficiency are identified. Participants have to wear the device for 7 consecutive days, 24 hours a day, for each timepoint measurements on the wrist of the non-dominant hand to determine the overall sleep conditions within a certain period. Removal (if any) of the actiwatch should be recorded in a logbook. Wake after sleep onset refers to the amount of time test subjects have spent awake after initially falling asleep and before they awaken for good.

    Time frame: up to 6-month follow up

  3. Total sleep time

    Actiwatch 2 Device with 0.025G ultra-high sensitivity will be used for data collection. Sleep parameters, including sleep latency, waking after sleep onset, total sleep time, and sleep efficiency are identified. Participants have to wear the device for 7 consecutive days, 24 hours a day, for each timepoint measurements on the wrist of the non-dominant hand to determine the overall sleep conditions within a certain period. Removal (if any) of the actiwatch should be recorded in a logbook. Total sleep time refers to the actual sleep time in a sleep episode.

    Time frame: up to 6-month follow up

  4. Sleep efficiency

    Actiwatch 2 Device with 0.025G ultra-high sensitivity will be used for data collection. Sleep parameters, including sleep latency, waking after sleep onset, total sleep time, and sleep efficiency are identified. Participants have to wear the device for 7 consecutive days, 24 hours a day, for each timepoint measurements on the wrist of the non-dominant hand to determine the overall sleep conditions within a certain period. Removal (if any) of the actiwatch should be recorded in a logbook. Sleep efficiency is the ratio of total time spent asleep (total sleep time) in an evening to the total amount of time spent in bed.

    Time frame: up to 6-month follow up

  5. The Chinese (HK) specific SF-12 v2©

    to evaluate the quality of life of the subjects, and has been found to have positive psychometric properties for use in the local population

    Time frame: up to 6-month follow up

  6. Patient Health Questionnaire

    to evaluate the depression status

    Time frame: up to 6-month follow up

  7. Insomnia Severity Index

    to evaluate sleep conditions

    Time frame: up to 6-month follow up

Other outcomes

  1. The 'Subjects' expectation questionnaire'

    Time frame: up to post-intervention at 6 weeks
