Self-Injury: Diagnosis and Treatment Clinical Trials Data presented on Clinical Trials Search isn't meant to be a substitute for qualified health advice, calls or treatment using a genuine doctor. We are not docs. Always consult your dr. on Self-Injury: Diagnosis and Treatment conditions. Clinical Trials Search.org is a site dedicated to listing clinical research studies in human subjects. Self-Injury: Diagnosis and Treatment Clinical research trials and Self-Injury: Diagnosis and Treatment healthcare trials occur in a lot of of places throughout the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the potency of new drugs. The intent of the studies / undertakings is to figure out certain human medical questions. Clinical trials are a popular means for mDs, government agencies, and private sector corporations to locate remedies for all kinds of circumstances, including Self-Injury: Diagnosis and Treatment. Self-Injury: Diagnosis and Treatment Clinical Trials and other clinical trials allow volunteers to obtain health treatment alternatives before they are available to the masses. Many times the participants undergo treatment for free, and sometimes they are paid for their time. Occasionally there is a cost for a Self-Injury: Diagnosis and Treatment clinical trial. Participants typically obtain the most effective healthcare available for their Self-Injury: Diagnosis and Treatment condition. Dangers are a reality, nonetheless, and can include extra or frequent mD trips, medical hazards (potentially life-endangering), and/or the treatment being uneffective. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Self-Injury: Diagnosis and Treatment
For Condition: Self-Injurious Behavior,Mental Retardation
Status: No longer recruiting
Sponsor(s): National Institute of Child Health and Human Development (NICHD) ,
Synopsis: Self-injurious behavior is behavior in which a person hurts or harms himself. This behavior sometimes occurs in people with mental retardation or autism. This study will evaluate self-injurious behavior in people with mental retardation or autism and will test the effectiveness of new treatments.
Details: It is unknown why some people with mental retardation and/or autism repeatedly and persistently injure themselves, some to the point of tissue damage and permanent scarring. Unraveling this mystery poses paradoxical biomedical and behavioral science questions and creates deeply troubling problems for practitioners and family members of affected individuals. Over the past decade, many cases of self-injurious behavior (SIB) have been treated successfully using behavioral interventions that teach communication and other functional skills. However, practical problems of implementation, costs associated with long-term treatment, and cases with no clear social profile suggest that there is still much to be learned about why people self-injure. Some forms of self-injury may involve intense stimulation of body sites sufficient to elicit the release and receptor binding of endogenous opioid peptides. This study will evaluate variables common to SIB and the neurophysiology of pain regulation. The study will also clarify the role of the endogenous opioids and pain mechanisms in self-injury. Participants with mild to profound mental retardation and/or autism will be observed for frequency of self-injury, duration and intensity of self-injurious behavior, and where on the body that behavior is directed. Following this characterization, participants’ saliva will be noninvasively examined for substance P, met-enkephalin, and cortisol as markers for altered pain transmission and predictors of response to treatment. After screening and SIB subtyping (i.e., social, nonsocial, or mixed), 37 participants whose self-injury is primarily nonsocial or mixed will be evaluated over 16 weeks. Participants will be randomized to receive either transcutaneous electric nerve stimulation (TENS, an opioid agonist treatment) or naltrexone (an opioid antagonist treatment). Participants whose self-injury is primarily socially motivated will be evaluated with TENS and will receive behavioral interventions through a technical assistance service delivery model. Follow-up evaluations will occur at Months 3 and 6.
