PRIMARY AIMS: (1) To compare the effects of cannabis versus oxycodone versus placebo on spontaneous chronic spine pain relief, as measured by change in score on the 10-point Numeric Rating Scale (NRS); (2) To compare the effects of cannabis versus oxycodone versus placebo on experimental pain analgesia, as measured by change in Experimental Pain Threshold (EPTh), in both patients with chronic spine pain and healthy controls. SECONDARY AIMS: (1) To compare the effects of cannabis versus oxycodone versus placebo on chronic spine pain, as measured by the Patient Global Impression of Change (PGIC) scale; (2) To compare the effects of cannabis versus oxycodone versus placebo on subjective reports of drug effects, psychoactive effects, and mood; (3) To compare the effects of cannabis versus oxycodone versus placebo on tests of neurocognitive functioning (Wechsler Adult Intelligence Scale (WAIS-III) Digit Symbol Test, the Hopkins Verbal Learning Test Revised (HVLT), and the Grooved Pegboard Test); (4) To compare the effects of cannabis versus oxycodone versus placebo on Standardized Field Sobriety Tests (SFST).

If you join the study, you will be placed by chance into one of two research groups: 1) exercise and a study pill or 2) no exercise and a study pill. The study pill could be DHEA (50 mg/day) or a placebo. A placebo is a pill that looks like medicine but is not real. DHEA is a naturally occurring hormone that declines with age. In postmenopausal women, nearly all estrogen and most testosterone comes from DHEA. DHEA is considered a food supplement.

The Program for Individuals with an Elevated Risk of Spondyloarthritis (PIERS) is a registry proposed by the affiliate members of the University of Colorado Program to Advance Spondyloarthritis Treatment (U.C.PAST). The purpose of PIERS is to identify individuals at risk for spondyloarthritis and study these individuals in a longitudinal manner in order to better understand the development of spondyloarthritis. Results from this study may provide information that contributes to our understanding of the complex relationships among immune dysregulation, genetic risk, subclinical phenotypes, and established spondyloarthritis phenotypes.

Regular physical activity is known to have positive effects on many health outcomes. In research, physical activity is often measured using activity monitors worn on the hip, wrist or ankle. These instruments determine how much physical activity a person does based on the amount of movement the person does. This is done with equations that use the data collected by the activity monitors. However, these equations are usually developed using measurements on healthy people. People who have movement disorders related to diseases such as Parkinson?s and Multiple Sclerosis, or conditions such as knee replacement, stroke, or arthritis have very different movement patterns than people without these diseases. Thus, the equations used to convert activity monitor data will not work well in people with these diseases or conditions. The purpose of this study is to develop equations to measure physical activity using activity monitors in people with movement limitations. Rather than creating specific equations for each individual disease and condition, we will perform simple tests to measure upper and lower body function, and then group people into different clusters based on these tests. Our preliminary studies show that these equations are more accurate than equations based on specific diseases or conditions.

This is a prospective, multi-center registry of patients treated in accordance with the cleared indications for the Smart, Penumbra Coil 400, and the Penumbra Occlusion Device. Data for each patient are collected in accordance with the standard of care at each participating hospital through one-year follow-up.

This is an unblinded, multi-center, pragmatic randomized controlled clinical trial of operative versus non-operative treatments for atraumatic rotator cuff tears. A sample size of 700 patients will be enrolled with approximately equal numbers of patients randomized to operative treatment (surgery + post-op physical therapy) and non-operative treatment (physical therapy only without surgery).

The results of the ultrasound will help determine if there are any significant radiologic findings or patterns seen in patients with CECS. Evaluation of ultrasonographic findings will be dependent on tissue density as measured by hypoechoic versus hyperechoic signal as well as muscle compartment thickness at its largest dimension.

i. To compare differences in muscle recruitment, gait patterns (kinematics & kinetics), spaciotemporal variables, functional movements (squats, lunges, sit-to-stand, and single leg steps), and pelvic tilt between patients with femoroacetabular impingement (FAI) and age-matched morphologically normal controls. ii. To compare differences in muscle recruitment, gait patterns, spaciotemporal variables, functional movements, and pelvic tilt between symptomatic and asymptomatic patients with FAI morphology. iii. To compare changes in muscle recruitment, gait patterns, spaciotemporal variables, functional movements, and pelvic tilt pre- and post-intra-articular hip injection in symptomatic FAI patients. iv. To test if anatomical variables (alpha angle, center edge angle, FAI version) are predictors of change in gait and movement patterns.
