Methods
The protocol of this exploratory prospective cohort study was registered in clinicaltrials.gov (NCT02398760).
Results
A total of 96 participants were assessed for eligibility between July 2014 and August 2015, and 70 participants were considered eligible. Six participants did not complete the program. Reasons for noncompletion were (1) lack of time (n=5) and (2) refusal to participate with no reasons provided (n=1). Therefore, 64 participants (91%) completed the lumbar stabilization exercise program. Table 1 describes the sample characteristics.

Discussion
Our findings show that scores from the DMC scale, CTTD, and PLE test measured at baseline do not predict improvements in pain intensity and disability following an 8-week lumbar stabilization exercise program. Our results are in accordance with recent evidence questioning the utility of this subgroup because of limited effectiveness, credibility, and validation.33, 34, 35
The CTTD failed to predict changes in clinical outcomes in patients with chronic LBP undergoing an 8-week lumbar
Conclusions
Our findings revealed that the DMC scale, CTTD, and PLE test clinical tests assessing motor control dysfunctions do not predict improvements in pain intensity and disability in patients with chronic nonspecific LBP undergoing an 8-week lumbar stabilization exercise program. The results from this study do not support claims that it is possible to identify a subgroup of patients with chronic LBP who would respond to a course of lumbar stabilization exercise program with clinical tests.
