Effect of Pulse Width With Spinal Cord Stimulation
PainChronic Pain1 moreThe primary objective of this study is to assess the effects of varying pulse width in suprathreshold dorsal column stimulation in patients with low back pain.
Spinal Cord Stimulation Versus Nerve Blocks and Physical Therapy
Complex Regional Pain SyndromeChronic Pain1 moreThe 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.
A Safety and Efficacy Study of Sufentanil Transdermal System in Patients With Chronic Pain Due to...
Chronic PainThe study hypothesis is that the safety and efficacy of sufentanil following transdermal application is comparable to sustained release morphine sulphate tablets in patients with chronic pain due to cancer.
The Mobile PTSD Coach App in Acute Injury Survivors
Chronic PainAcute Pain Due to Trauma1 moreThis project is a preliminary randomized controlled trial testing the potential impact of the PTSD Coach mobile application at reducing posttraumatic stress and pain symptoms among acutely injured trauma patients. Immediately following the injury, patients will be randomly assigned to use the PTSD Coach app, or to the treatment as usual condition.
Marijuana Use, Strength Training, and Alcohol Consumption (MUSTAC) Study
Chronic PainSelf-medication of pain by consuming alcohol and marijuana is common. However, the research regarding pain as a determinant for alcohol and marijuana use has relied on laboratory pain induction paradigms with limited clinical relevance. The study will assess demand for alcohol and marijuana before and after delayed onset muscle soreness (DOMS) induction in co-users. This will provide a clinically relevant, but time-limited, model for the effects of musculoskeletal pain on demand.
DNIC Using Deep Learning and Artificial Intelligence
Chronic PainChronic pain (CP) is disabling for people triggering important costs for society. A deficit of diffuse noxious inhibitory controls (DNIC) is one of the CP mechanisms. DNICs are evaluated in research setting using a CPM protocol (conditioned pain modulation). There is a lack of reference values on the effectiveness of DNICs. Wider research on DNIC will help to understand CP and to develop a clinical screening test evaluating DNICs. This study aims more specifically to determine whether it is possible to develop a facial recognition system to automate pain measurement and the effectiveness of pain control mechanisms.
Flotation-REST for Chronic Pain, Stress, and Sleep
HealthyChronic Pain1 moreThis randomized crossover trial aims to examine the effects of Flotation-REST (Reduced, Environmental, Stimulation, Technique/Therapy) compared to laying in a dark room (with reduced environmental stimulation) for those with chronic musculoskeletal pain. This design will allow for comparisons between the two interventions on daily diary assessments of pain, stress, and sleep, both between groups and within individuals.
Transcranial Magnetic Stimulation (TMS) for Thoracic Surgery
Thoracic SurgeryChronic Pain2 morePatients with high severity of post-surgical pain scores will be randomized to transcranial magnetic stimulation (TMS) vs sham TMS groups. Both group of patients will have 10 TMS sessions during 5 days. Our hypothesis is that, the reduction in the severity of pain scores will be greater among those patients who are randomized to active TMS group compared to sham TMS group. The investigators will explore how improvements in pain correlate with changes in brain network connectivity.
Study on the Efficacy of Infiltration of Upper Cluneal Nerves in Chronic Pain Related to Cluneal...
Cluneal SyndromeNerve Entrapment SyndromeLower back pain is a very common complaint in the Chronic Pain Clinic. Its etiology is nonspecific in 85% of the cases. In 1957, Strong and Davila reported that the superior cluneal nerves (SCNs) and middle cluneal nerves (MCNs) can be entrapped around the iliac crest, suggesting a causal relationship between this entrapment (SCN-Entrapment, SCN-E) and low back pain symptom. This is known today as "cluneal syndrome". Cluneal syndrome remains poorly investigated and is currently a diagnostic challenge. Various types of lumbar movements exacerbate its occurence. The most common theory regarding the origin of this pain evokes that is primarily due to a mechanical cause linked to stenosis or adhesions of fibrous tissue around the cluneal nerves causing distress. The hypothesis is that the investigator can reduce the pain related to the syndrome of superior cluneal origin thanks to a "volume effect" which aims to detach adhesions and/or aponeurotic stenoses that cause a distress of cluneal nerves. The aim of this study is to assess the effectiveness of the cluneal nerve block using theThomas Dahl Nielsen ultrasound based technique in patients with chronic low-back pain related to SCN-E. To this end, the investigator will compare physiological serum injection versus local anaesthetic injection, with the aim of reducing short-term pain and improving quality of life.
