Filter by:This project is a prospective observational study that will involve the participation of 25 volunteers that qualify for having knee osteoarthritis, are going to be having gastric bypass surgery and are willing to participate in this study which is designed to last up to two years. Potential candidates will be interviewed using a standard set of questions related to the study
The purpose of this study was to examine a low and high dose of tapentadol extended release tablet taken orally twice a day to reduce pain in subjects suffering from chronic moderate to severe pain due to osteoarthritis of the knee during a 4-week period. Subjects steadily increased their dose up to the low (100 mg) or high (200 mg) dose. Pain relief was compared to subjects taking placebo tablets or oxycodone extended release tablet, 20 mg. The serum concentrations and safety of tapentadol and oxycodone were also examined.
Pain at the front of the knee is a common condition treated by physical therapists. Treatment may consist of generalised strengthening exercises directed at the quadriceps muscle or specific retraining aimed at restoring motor control at the knee. This study compared these two exercise programs in a group of people who were painfree at the time to evaluate their effect on motor control. It was hypothesised that only the motor retraining program would influence motor control at the knee.
The purpose of this study is to gain a better understanding of the effects of lumbopelvic manual therapy on lower extremity biomechanics and arthrogenic muscle response. As a result of this study, we also hope that physical therapists, athletic trainers, and other physical medicine rehabilitation providers will gain a better understanding of lower extremity injuries and have the scientific evidence to provide patients with techniques which would allow for efficient return to activities of daily living without restrictions and possibly prevent future injuries and minimize risk of osteoarthritis. The objectives of this study are to: - Determine the amount and duration of arthrogenic muscle response of quadriceps muscles following lumbopelvic joint manipulation. - Determine the effects of lumbopelvic joint manipulation on temporospatial parameters of gait such cadence, step length, velocity and mean peak lower extremity joint moments. - Determine if a correlation exists between patellofemoral joint pain and lumbopelvic joint dysfunction. - Determine the amount of change in clinical outcome measure scores following lumbopelvic joint manipulation.
Primary Total Knee joint replacement surgery is highly successful surgery for relieving pain and improving function in patients with disabling arthritis. Unfortunately, like all biomedical devices, prosthesis failure is a complication of knee replacement surgery that leads to disabling pain, stiffness and loss of function. Approximately 1% of the knee replacements fail every year leading to a 20% failure rate over 20 years. The common causes of failure of prosthetic joint are infection, loosening, trauma or wear of the prosthesis. Currently, a revision surgery is the best option for long term pain relief (analgesics or other pain medications are options but are of limited benefit). Surgery may not be feasible in patients due to advancing age, other medical conditions and surgical/technical difficulties or patient's choice. In addition, the results from revision surgery are not as good as the initial knee joint surgery. Therefore, there is a great need for a novel, targeted therapy that provides an option to patients who are unfit, unable, or unwilling to undergo surgery. In the investigators' recent pilot study, a single injection of Botulinum toxin A (Botox) in painful natural knee, ankle and shoulder joints of patients with various types of arthritis led to significant and durable improvement in pain and function and was safe to use. The investigators propose this 6-month study to compare pain relief, improvement of function and safety of an injection of Botulinum toxin compared to placebo in patients with a painful prosthetic knee joint. Both patients and investigators will be blinded to the treatment assignment to a patient until the study is completed. The investigators will assess the amount and duration of pain relief, improvement in function and short term safety of Botulinum toxin using standard validated measures. Patients will be evaluated at baseline, 2 weeks, 1-, 2-, 3-, 4- and 6-months after a single injection of either placebo or BoNT/A in the hip or knee prosthesis. The six-month follow-up is to assess the duration of meaningful pain relief. If successful, this will offer a new treatment option for patients with a chronically painful knee prosthetic joint, provide more insight into the origin and cause of pain in prosthetic joints and direct future investigations in new directions.
