Hypothesis: A mechanical device when applied to the back of the neck at the onset of a menopausal hot flash will attenuate the severity and duration of symptoms providing women with a reassuring non-hormonal intervention to improve quality of life in the menopausal transition. This pilot study will evaluate the effectiveness of this unit.

The mechanism of action of the device will not be revealed in advance.

Condition Intervention Phase
Hot Flashes Device: Menopod Device: Inactive device Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Evaluation of a Novel Mechanical Device for Relief of Menopausal Vasomotor Symptoms.

Further study details as provided by Dr. Robert Reid, Queen's University:

Primary Outcome Measures:
  • Hot flash score and duration [ Time Frame: Change from baseline to end of study (week 4). ]
    Hot flash score is a product of frequency x intensity (Sloan 2001). Duration (minutes) will be recorded in diary.

Secondary Outcome Measures:
  • Quality of Life (QOL) and Anxiety [ Time Frame: Change from baseline to end of study (week 4). ]

    Subjects will complete the Hot Flash Related Daily Interference Scale once during the evaluation phase and once per week over the four week treatment phase (Carpenter 2001). This validated questionnaire assesses the impact of hot flashes on daily activities and overall QOL. They will also complete the Zung Self-Rating Anxiety Scale (Zung 1971). This validated 20-item questionnaire measures anxiety with established normal, mild to moderate, marked to severe and extreme levels.

Arms Assigned Interventions
Active Comparator: Menopod device
Device: Menopod
The mechanism of action of the device will not be revealed in advance.
Sham Comparator: Sham device
Inactive device.
Device: Inactive device
Other Name: The mechanism of action of the active device is disabled.

Detailed Description:

This is a pilot study to test logistics and gather information for planning the definite trial. We will randomly allocate 40 subjects to receive either the active Menopod device (n=20) or a sham device with the mechanism disabled (n=20).

We will recruit menopausal women with moderate to severe hot flashes (as defined by FDA standards this means a minimum of 7 per day).

The two primary outcome parameters are the hot flash score which is the product of frequency x intensity (Sloan 2001), and the average duration (in minutes) of hot flash episodes over the course of one day. These outcomes will be self-recorded by subjects in a diary designed by our research team on five separate days throughout the course of the study, once during the evaluation phase and once per week over the four week treatment phase. The two summary measures will be the changes from baseline to the last record collected for hot flash scores and average durations. Delta values (assessment phase minus fourth treatment period) will be compared between the two treatment groups (active versus sham device) using t tests (IBM SPSS Statistics version 21).
