Use of Transcutaneous Electrical Nerve Stimulation for Reducing Biologic Injection Site Pain(TENS Study)

The purpose of this research study is to determine the efficacy of TENS therapy in reducing the pain experienced by patients during and after the injection of biological medications. The study team is interested in recording the level of pain reduction from TENS therapy to determine if this intervention is effective at reducing discomfort associated with medication administration so that it may possibly be applied to other patients in an effort to reduce treatment-related discomfort, anxiety, and possibly increase adherence. A total of 10-20 subjects at one research site will be recruited to participate, specifically, individuals who receive the injection of medication in two separate sites. The inclusion criteria will be an age of \> 18 years old, a diagnosis of psoriasis, and currently receiving biologic medication injection in two sites during their dermatology clinic visit. The first step is to administer the biologic medication in one thigh without the use of TENS therapy. This is done to establish a control, or baseline, for how painful the injection experience is. The second step involves a study team member applying two to four TENS unit pads (made of adhesive gel) to the skin of your thigh approximately two centimeters from the site where injection of the biological medication takes place. The device will be turned on during the injection of the medication. Medication injection will take place by either the patient or nursing staff as it would normally take place without involvement in this study. Immediately after both steps, subjects will be given a brief survey to determine their pain level.
