The purpose of this study is to examine the relationship between reflexes in the leg and the presence of neuropathic pain. The researchers are recruiting 30 individuals with spinal cord injury (SCI) total, 15 individuals with neuropathic pain due to SCI and 15 individuals without neuropathic pain. For this portion of the study, there are 2 visits. The first visit will examine cutaneous reflexes in the leg. During the second visit, the study team will assess sensation in the leg and administer questionnaires about pain, functioning, and quality of life.

The purpose of the second part of the study is to examine the effect of reflex training in the leg to decrease neuropathic pain. For this, the researchers are recruiting 15 individuals with neuropathic pain due to spinal cord injury to participate in the reflex training procedure. The study involves approximately 50 visits with a total study duration of about 6.5 months (3 months for baseline and training phases followed by 1 month and 3 month follow-up visits).

The purpose of this research study is to determine how well and safe deucravacitinib, an investigational/non-approved United States Food and Drug Administration (US FDA) medication, is in treating Systemic Lupus Erythematosus (SLE, lupus).

Participation in the study will involve being assigned deucravacitinib or a placebo (a drug that looks likes the study medication but does not contain any medication) and completing a series of in person clinic visits much like those completed as part of standard of care. Blood and urine samples will be collected for both routine health and safety tests as well as research/experimental testing.

The study will require 16 visits over a period of 14 months. There is an optional extension to the study possible, should you wish to continue and the study doctor feels that you remain a good candidate for participation. Study medication is provided and compensation is available for participation.
