Individuals with chronic low back pain and other chronic pain conditions have been shown to have altered somatosensory, the ability to sense input to the tissue, which is processed in the primary somatosensory cortex or S1. Two-point discrimination is currently the best clinical tool utilized to assess an individual's ability to sense touch. This study will assess TPD changes after a course of standard physical therapy care with the addition of sensory training.

| Tactile acuity as measured by two-point discrimation | measured using a Caroline 2-point discriminator tool. TPD is the most widely accepted objective measurement of tactile acuity in the clinical setting | Performed at baseline visit, 4th week of treatment, and at final visit (8 +/- 2 weeks). |
| Measure | Description | Time Frame |
|---|---|---|
| Pain as measured by numeric pain rating scale | The NPRS is an 11-point numerical pain rating scale used to measure pain. Patients rate pain ranging between 0 (no pain) and 10 (worst pain imaginable) | Performed at baseline, 4th week of treatment, and final visit (8 +/- 2 weeks). |

measured using the Freemont Back Awareness Questionnaire (FreBAQ), a multi-item, self-report questionnaire designed to quantify distorted perception of the back in people with CLBP |
| Performed at baseline, 4th week of treatment, and final visit (8 +/- 2 weeks). |
| Tactile Localization Accuracy | measured by the number of correct responses out of 9 attempts for stimulation of the 9-grid chart | Performed at baseline, 4th week of treatment, and final visit (8 +/- 2 weeks). |
| Function | measured by the Oswestry Disability Index (ODI), 10 patient-completed questions in which the response options are presented as 6-point Likert scales. Scores range from 0% (no disability) to 100% (most severe disability | Performed at baseline, 4th week of treatment, and final visit (8 +/- 2 weeks). |
