Somatosensory Assessment and Rehabilitation of Allodynia (SARA)

Complex Regional Pain SyndromePeripheral Nerve Injuries1 more

This pilot study will test a new therapy, somatosensory rehabilitation, for the painful sensitivity experienced by persons with nerve injuries and/or complex regional pain syndrome (CRPS). Several methods for measuring pain and sensitivity that emphasize the person's evaluation of their own symptoms and the impact of these symptoms on their daily activities will also be tested to make sure they are consistent and accurate. Previous research has suggested one of the assessments may also be used to assist in the identification of CRPS: this simple test will be evaluated to see if it can accurately identify persons with this disorder (for which there is currently no diagnostic test). Together, this will improve treatment of CRPS through early, accurate diagnosis and the ability to measure important changes in this painful condition, and set up future studies for this new rehabilitation treatment method.

"Liposomal Encapsulated Vitamin C in Complex Regional Pain Syndrome"

Complex Regional Pain Syndrome I of Lower Limb

Abstract: Complex regional pain syndrome (CRPS) is a significant complication in operated osteoarticular pathology and may adversely affect patient's quality of life. Vitamin C is an anti-oxidant and a neuro-modulating agent. Intake of vitamin C appears to be the only preventative factor. The objective of this study seeks to assess the effectiveness of liposomal conditioning of vitamin-C in reducing CRPS and to show evidence that it is more effective than taking vitamin C in its usual form.

Offset Analgesia as a Measure of Central Sensitization in Children

Chronic Pain SyndromeChronic Daily Headache3 more

Pediatric chronic pain disorders are common and consequential in Western societies, occurring in 25-80% of population-based samples with a median prevalence of 11-38% and significant pain-related disability in 3-5% of these children. Pediatric chronic pain disorders have a negative impact on many aspects children's lives including mobility, night sleep, school attendance, peer relationships, family functioning, and overall quality of life. Parents caring for these children risk loss of parental earnings, and these disorders place a high financial burden on healthcare. In a nationally representative sample in the United States, costs related to health care were significantly higher ($1,339 per capita) for children with chronic pain disorders compared to children with common pediatric health conditions of ADHD, asthma and obesity. In children with clinical chronic pain conditions, such as daily headaches or fibromyalgia, chronic pain is presumably a persistent state of an overly excitable nervous system. This phenomenon known as central sensitization is characterized by excessive pain sensitivity that occurs in response to non-painful stimuli, such as light touch or contact with clothing, and slightly painful stimuli, such as a light pinprick. This hypersensitivity results from peculiar changes in the working of the central nervous system, including the spinal cord and brain, and leads to unusual intensification of pain that is out of proportion to the inciting stimulus. For example, light touch from clothing on the skin is perceived as intensely painful. Central sensitization is also thought to contribute to the spreading of pain to other body sites in several chronic pain disorders. In chronic pain disorders, the function of the central descending inhibitory modulating system is likely impaired and is traditionally measured by a phenomenon identified as "conditioned pain modulation (CPM)" and more recently measured by a phenomenon of "offset analgesia" (OA). The OA test is more robust than the CPM test and likely more acceptable to most patients, especially children, because it is shorter in duration and uses a more tolerable painful stimulus. Compared to CPM, the OA test is more tolerable because it is conducted using a painful test stimulus that is less than the maximal (suprathreshold). Additionally, the time of exposure to the painful stimulus is significantly shorter, a few seconds, in the OA test compared to CPM. The central descending inhibitory pathway that modulates pain as tested by OA is functional and mature in healthy children as young as 6 year of age, but it has yet to be investigated in children with chronic pain disorders. The investigators plan to test OA responses in a population of common pediatric pain disorders with overlapping symptomology attributed to central sensitization (such as chronic musculoskeletal pain, chronic abdominal pain and chronic headaches and chronic regional pain syndromes) and compare their responses with an age- and sex-matched control group. The characteristics of OA responses in each group will allow for assessment of the presence or absence of central sensitization as a mechanism driving the persistent, abnormal pain in a subgroup of these chronic pain disorders. The investigators hypothesize that central sensitization is the potential contributory mechanism of the central nervous system heightened sensitivity to two testing stimuli of painful (moderate heat discomfort sensation) and non-painful (warmth sensation) in children with chronic pain disorders. These types of sensations mimic those that children would be expected to experience their natural environment during typical activities of daily living such as showering/bathing in warm water or hand washing. Additionally, the Pain Sensitivity Questionnaire (PSQ) and Central Sensitization Inventory (CSI) will be used as clinical screening tools for subjective report of sensitization symptoms, and are simple and easy to administer in a clinical setting. The investigators hypothesize that these measures will correlate with the objective offset analgesia responses thus allowing for assessment of central sensitization in children with chronic pain disorders. These tests are advantageous because they are feasible to perform rapidly in a clinic setting and have utility for measurement of patient responses to therapeutic interventions. If this concept is supported by this study, future studies could utilize OA to examine the effects of various pharmacological and physical interventions used to manage children with chronic pain disorders including intensive interdisciplinary rehabilitation or specific interventions such as aerobic exercise, which likely modulates pain via similar mechanisms.

Spinal Cord Stimulation Versus Nerve Blocks and Physical Therapy

Complex Regional Pain SyndromeChronic Pain1 more

The primary objective of this study is to compare the efficacy of SCS using the Precision implantable neurostimulation device and conventional medical treatment (nerve blocks + physical therapy) in subjects with recently-diagnosed Complex Regional Pain Syndrome (CRPS) after some more conservative treatments have failed. There are significant numbers of patients with CRPS in whom conventional treatment is ineffective and SCS is used only as a last resort. If SCS is effective earlier in the treatment continuum, it would provide a much needed treatment alternative and increase awareness of the utility of SCS for this indication. It is also possible that early intervention with SCS may limit disease progression.

Prophylactic Administration of Vitamin C in Wrist Fractures

RSD (Reflex Sympathetic Dystrophy)Algodystrophy1 more

Complex Regional Pain Syndrome or posttraumatic dystrophy is a pain syndrome which develops after a trauma, surgery or for unknown reason. The incidence after wrist fractures varies in literature from 2 - 37%. The female sex is involved three times as much as the male sex. There is one study in literature which describes a prophylactic effect of vitamin C after wrist fractures. Goal of this study is to search for a dose dependent effect of vitamin C and to replicate these earlier findings.
