Change From Baseline to Week 4 for Worst Pain Secondary · Baseline and Week 4

The Brief Pain Inventory (BPI) includes a 'worst pain' severity scale. Subjects rate their worst pain in the last 24 hours on a scale from 0 (no pain) to 10 (pain as bad as you can imagine).

Number of Subjects With a PGI-C Response (Defined as "Much Improved" or "Very Much Improved") at Week 4 Secondary · Week 4

The Patient Global Impression - Change (PGI-C) is the patient-reported counterpoint to the CGI-C (Guy, 1976). The qualitative assessment of meaningful change is determined by the patient in response to the question, "Compared to your condition at the beginning of treatment, how much has your condition changed?" Scores are as follows: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; and 7=very much worse.

Number of Subjects With a CGI-C Response (Defined as "Much Improved" or "Very Much Improved") at Week 4 Secondary · Week 4

The Clinical Global Impression - Change (CGI-C) is a 7-point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to the baseline state at the beginning of the intervention. The rater selects one response based on the following question, "Compared to your patient's condition at the beginning of treatment, how much has your patient changed?" Scores are as follows: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; and 7=very much worse.

Change in the Weekly Average of the Daily Sleep Score on the DSIS From Baseline to Weeks 1, 2, 3, and 4 Secondary · Baseline to Weeks 1, 2, 3 and 4

The Daily Sleep Interference Scale (DSIS) is an 11-point response scale that quantifies sleep interference due to pain. It is a single-item measure that is completed once daily, upon awakening, to accurately capture variability in sleep interference due to pain on a daily basis, thus minimizing recall bias. Patients are asked to select the number that best described how much their pain has interfered with their sleep during the last 24 hours on a scale from 0 (pain does not interfere with sleep) to 10 (pain completely interferes with sleep). The subjects were to record the value that most clo

Change in BPI - Interference Scale From Baseline to Week 4 Secondary · Baseline to Week 4

The Brief Pain Inventory (BPI) interference score measures how much pain has interfered with seven daily activities scored on a scale from 0 (does not interfere) to 10 (completely interferes). It is scored as the mean of the seven interference items.

Change in the BPI - Pain Scale From Baseline to Week 4 Secondary · Baseline to Week 4

The Brief Pain Inventory (BPI) pain score is a composite of 4 items assessing pain severity (worst, least, average and right now). Subjects rate their pain in the last 24 hours on a scale from 0 (no pain) to 10 (pain as bad as you can imagine). It is scored as the mean of the four pain items.

Change in the RMDQ From Baseline to Week 4 Secondary · Baseline to Week 4

The modified Roland-Morris Disability Questionnaire (RMDQ) is a self-administered, 24-question physical disability measurement assessment that evaluates the effect of back pain on functioning. Each question requires a "yes" or "no" answer; 1 point is scored for each positive response. The total scores are determined on a scale of 0 ("no disability") to 24 ("severe disability").
