Measure Description |
Time Frame |
---|---|---|
Mean Change in Quality of Life From Baseline to 6 Months Post-permanent Implant, Assessed by the EuroQuol-5 Dimensions (EQ5D) Questionnaire
Time Frame: Baseline to 6 Months
|
EQ5D is a standardized instrument for use as a measure of health outcome applicable to a wide range of health conditions and treatments.
It provides a simple descriptive profile and a single index value for health status.
The EQ5D-3L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each dimension has 3 levels: no problems, some problems, extreme problems.
A visual analog scale (VAS) for health is also included in the measure as a patient-reported estimate of overall health status.
EQ5D Index scores range from - 0.594 (min) to 1 (max).
An EQ-5D summary index is derived by applying a formula that attaches values (weights) to each of the levels in each dimension.
Higher values represent better outcomes.
|
Baseline to 6 Months
|
Mean Change in Pain Catastrophizing From Baseline to 6 Months Post-permanent Implant, Assessed by the Pain Catastrophizing Scale (PCS)
Time Frame: Baseline to 6 Months
|
The PCS is a validated scale that measures the magnitude of catastrophizing (negative thoughts and feelings while a patient is experiencing pain).
Subjects answer questions about how they feel and what they think about when they are in pain (i.e., not at the current moment).
The scale includes 13 statements concerning pain experiences that are rated on a scale between 0 'not at all' and 4 'always'.
The scale is self-administered and takes 5 minutes to complete.
A higher score indicated a higher level of catastrophizing.
PCS total scores range from 0 (min) to 52 (max).
Three sub-scales consists of rumination, magnification, and helplessness.
Rumination scores range from 0 (min) to 16 (max), Magnification scores range from 0 (min) to 12 (max), and helplessness scores range from 0 (min) to 24 (max).
The total PCS score is the sum of the three subscales.
|
Baseline to 6 Months
|
Mean Change in Anxiety From Baseline to 6 Months Post-permanent Implant, Assessed by the State-Trait Anxiety Inventory (STAI)
Time Frame: Baseline to 6 Months
|
The State-Trait Anxiety inventory is a self-administered screening for anxiety.
The STAI has 40 items, 20 items allocated to each of the S-Anxiety and T-Anxiety subscales.
All items are rated on a 4-point scale from 1 to 4. It clearly differentiates between the temporary condition of "state anxiety" and the more general and long-standing quality of "trait anxiety" by providing a score for each.
Higher scores suggest greater levels of anxiety.
The range of possible scores for the STAI varies from a minimum score of 20 to a maximum score of 80 on both the trait and state subscales.
The total score is the sum of the two subscales.
STAI total scores range from 40 to 160.

Time Frame: Baseline to 6 Months
|
The PHQ9 is a multipurpose, validated instrument for screening, diagnosing, monitoring and measuring the severity of depression.
The questionnaire consists of 9 questions that rate the frequency of the symptoms of depression.
A follow up non-scored question screens and assigns weight to the degree to which depressive problems have affected the patient's level of function.
The responses range between 4 choices (0=not at all to 3=nearly every day).
Higher scores indicate a higher likelihood of major depression.
PHQ-9 scores range from 0 (min) to 27 (max).
|
Baseline to 6 Months
|
Mean Change in Fear Avoidance From Baseline to 6 Months Post-permanent Implant, Assessed by the Tampa Scale for Kinesiophobia (TSK)
Time Frame: Baseline to 6 Months
|

The scale is based on the model of fear avoidance, fear of work related activities, fear of movement and fear of re-injury.
The TSK has also been linked to elements of catastrophic thinking.
The scale can be useful in measuring unhelpful thoughts and beliefs about pain in people with chronic pain.
Total TSK-11 scores range from 11-44 points.
Higher scores represent worse outcomes.
|
Baseline to 6 Months
|
Mean Change in Sleep From Baseline to 6 Months Post-permanent Implant, Assessed by the Medical Outcome Study (MOS) Sleep Scale
Time Frame: Baseline to 6 Months
|
The MOS sleep scale is intended to assess the extent of sleep problems and measures 6 dimensions of sleep, including initiation, maintenance, quantity, adequacy, drowsiness and respiratory impairments.
It includes 12 questions with the first question assessing how long it takes the subject to fall asleep.
The second question asks how many hours each night the subject slept.
The remaining 10 questions have a range of 6 responses from 1="all of the time" to 6="none of the time".
The scale is self-administered and validated.
MOS Sleep scale scores range from 0 (min) to 100 (max).
Higher scores represent worse outcomes.
|
Baseline to 6 Months
|
Mean Change in Physical Function From Baseline to 6 Months Post-permanent Implant, Assessed by the Patient-Reported Outcome Measure Information System (PROMIS) Physical Function Scale
Time Frame: Baseline to 6 Months
|
The PROMIS Physical Function short form is an 8-item instrument designed to measure physical capability rather than actual performance of physical activities.
The scale measures universal physical function rather than disease-specific impairment and assesses current function rather than function over a specified time period.
Each question has five potential response options ranging in value from one to five to give a total score ranging from 8 to 40.
Scores are converted into t-scores where the average for the general US population is 50 and the SD is 10.
Higher scores indicate better physical function.

Mean Change in Physical Function From Baseline to 12 Months Post-permanent Implant, Assessed by the Patient-Reported Outcome Measure Information System (PROMIS) Physical Function Scale
Time Frame: Baseline to 12 Months
|
The PROMIS Physical Function short form is an 8-item instrument designed to measure physical capability rather than actual performance of physical activities.
The scale measures universal physical function rather than disease-specific impairment and assesses current function rather than function over a specified time period.
Each question has five potential response options ranging in value from one to five to give a total score ranging from 8 to 40.
Scores are converted into t-scores where the average for the general US population is 50 and the SD is 10.
Higher scores indicate better physical function.

Mean Change in Pain From Baseline to End of Trial System (Post-permanent Implant), Assessed by the Numeric Rating Scale (NRS)
Time Frame: Baseline to end of trial system evaluation, approximately 5 to 7 days of BurstDR stimulation
|
The pain NRS consists of 1 question that will be asked by interviewing the subjects.
Patients will be asked to rate, from 0 (no pain) to 10 (worst imaginable pain), their average pain over the past 24 hours specific to the area(s) of chronic pain being treated.
A higher score indicates greater pain intensity.

Rate of Global Improvement of the Patient by Using the Patient Global Impression of Change (PGIC) at the End of Trial System Evaluation
Time Frame: End of trial system evaluation, approximately 5 to 7 days of BurstDR stimulation
|
The PGIC is a categorical rating scale used to evaluate the subject's impression of change in his/her condition since the beginning of the study treatment.
The subject rates their overall change in activity limitations, symptoms, emotions and overall quality of life related to his/her condition on a seven-point categorical scale via an interview technique.
The categories are as follows: 1-no change, 2-almost the same, 3-a little better, 4-somewhat better, 5-moderately better, 6-better, and 7-a great deal better.
Although this tool does not specify the area of change (e.g., pain, function, quality of life, etc.), it allows for an overall integrated assessment from the prospective of the subject.
PGIC values of 6 or 7 are reported to correlate best with actual change.
