Insomnia and Osteoarthritis Study
March 13, 2019 updated by: Johns Hopkins University
The Efficacy of Eszopiclone (Lunesta) for Chronic Insomnia Associated With Osteoarthritis.
This research is being done to evaluate the effects of a sleeping pill (eszopiclone, Lunesta)in patients with arthritis of the knee who also suffer from chronic insomnia.
This study will test whether Lunesta improves sleep, pain sensitivity, and daytime symptoms in patients with knee pain.

|
The ISI is made up of 7 questions, each possible of earning a score of 0-4, making the total range 0-28, where 0 indicates no severity/no problem with sleep and therefore no insomnia, or 28, being very severe with the highest level of insomnia

PPTh:a somedic algometer's 1cm2 rubber probe was placed over muscle belly, with pressure increasing steadily at constant rate (30kPA/Sec), until subject indicated that s/he "first felt pain."
PPTh ratings were obtained on right brachioradialis & right trapezius in a random order (average was taken from both areas at each time point).
During each cold pressor task, participants immersed contralateral hand (left) up to wrist, in a circulating cold water bath maintained at 4°C. 20 seconds after commencing hand immersion, PPTh was re-assessed on either right brachioradialis or right trapezius (the same site as baseline assessment).
After PPTh assessment, participants removed hands from water.
DNIC was measured as the % change in PPTh during cold pressor, relative to baseline PPTh [i.e., (mean PPTh during cold pressor / mean PPTh prior to cold pressor)*100].
Increase in PPTh during cold pressor (i.e., percentage scores above 100) reflects normal functioning of pain-inhibitory processes.

TS :maximum windup pain rating - first windup pain rating (0-100).
Contact heat stimuli at non tissue damaging temperatures were delivered using computer driven, peltier-element-based stimulator (Medoc, TSA II), with a 9 cm2 probe applied to left forearm.
In order to assess temporal summation, three sequences of 10 heat pulses each (with stimulus temperatures of 46 degrees C, 48 degrees C, and 50 degrees C, in random order) were applied to left dorsal forearm.
The thermode remains in fixed position during administration of 10 heat pulses that constitute a sequence.
Within each sequence, successive thermal pulses at a given temperature are delivered for a duration of approximately 0.5 sec each, with a 2.5-sec inter-pulse interval.
The rate of rise & fall of the thermode temp. is set at the device max .of 10 degrees C / S. Subjects verbally rate the perceived intensity of each thermal pulse on a 0-100 rating scale & may terminate the procedure at any time.100=max

Heat Pain Threshold
Time Frame: Mean of baseline, 6 week follow-up and 12 week follow-up
|
Contact heat stimuli at non tissue damaging temperatures were delivered using computer driven, peltier-element-based stimulator (Medoc, TSA II), with a 9 cm2 probe applied to the left forearm.
The thermode was affixed snugly via Velcro straps to ensure even skin contact and repositioned to an adjacent site after each trial to minimize sensitizationHPTh was assessed on the left ventral forearm using an ascending method of limits paradigm; from a non-painful 32°C baseline, the temperature was steadily increased at 0.5°C/sec.
Two trials of heat pain threshold were conducted.
Averages of both trials are presented from respective time point below.
Subjects push a button when the stimulus "first feels painful" The temperature (degrees Celsius) at the time button is pushed is automatically recorded.

Pressure Pain Threshold
Time Frame: Mean of baseline, 6 week follow-up and 12 week follow-up

The algometer's 1cm2 rubber probe was placed over the muscle belly, with the pressure increased steadily at a constant rate (30kPA/Sec), until the subject indicated that s/he "first felt pain."
PPTh was assessed 2 times each, bilaterally, at (in a randomized order) the masseter muscle trapezius muscle, and at the proximal third of the brachioradialis muscle (forearm).
The scores from each location were averaged for each participant at that respective time point.
The same site was never stimulated consecutively.
