Examination of Nociscan Impact on Discogenic Low Back Pain Surgical Outcomes
Recruiting
This study is looking into how safe and useful NOCISCAN is. NOCISCAN is a software as a Service (SaaS) tool that uses Magnetic Resonance (MR) spectroscopy. Nociscan (instead of 'It') leverages MRS to noninvasively help physicians distinguish between painful and nonpainful discs in the lumbar spine. The randomized controlled trial will compare the blinded and unblinded cohorts and their corresponding surgical outcomes with the Nocigram reports, generated prior to treatment, for each patient."

Phase I Single Ascending Dose and Multiple Ascending Doses of Oral AFA-281 in Healthy Volunteers
Recruiting
Phase I Part 1 (single ascending dose):
Double-blind dosing will occur in healthy volunteers in 4 cohorts of 8 subjects each. Six subjects in each cohort will be randomized to receive AFA-281 and 2 subjects will be randomized to receive the matching placebo. At the end of the Part 1 study is to evaluate the safety and tolerability of AFA-281. Following completion of each cohort, bioanalytical analyses will be conducted to evaluate the pharmacokinetic profile.

Continuous Versus Single Injection Adductor Canal Blocks for Outpatient Total Knee Arthroplasty
Recruiting
This is a single-center pilot study to determine if an adductor canal continuous nerve block is superior to single injection nerve block following total knee arthroplasty. Investigators will randomize participants to either continuous nerve block or single injection nerve block for the adductor canal preoperatively. They will assess differences in pain (measured in numeric rating scale), opioid consumption, and physical therapy milestones from postoperative day 0 to 7.

Transcranial Magnetic Stimulation for Chronic Neuropathic Pain
Recruiting
Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stim... Read More
