Brief Summary: The goal of this study is to determine if mind body therapies can help people suffering from chronic back pain. The study is a randomized, partially blinded trial examining the effectiveness of mind body interventions (treatment arms) in reducing disability from back pain and alleviating back pain in participants as compared to usual care (control arm ). The investigators will secondarily investigate whether mind body interventions improve participant quality of life and reduce the need for pain-related hospitalization.

The purpose of this study is to assess the feasibility, acceptability, and efficacy of self-administered transcranial direct current stimulation (tDCS) in older adults with knee osteoarthritis (OA).

Study Description: Brief Summary: Specific Aims Significance: Intra-articular, prearthritic hip disorders (PAHD) result in substantial dysfunction in young adults and are proposed precursors to hip osteoarthritis (OA). Our long term goal is to develop effective treatment strategies for people with PAHD that will improve function, decrease pain and prevent or delay the onset of OA. The purpose of this study is to compare movement pattern training (MoveTrain) and manual therapy (ManTher) in their effect on post-treatment, patient-reported outcomes and targeted impairments thought to contribute to PAHD.

Study Description: Brief Summary: Chronic knee pain from osteoarthritis (OA) is commonly treated with total knee arthroplasty (TKA) when conservative therapies fail to provide pain relief. More than 600,000 TKAs are performed in the U.S. annually, a number that continues to increase. A logistic-regression model suggests that the incidence rate of TKA will increase by 143% in the United States by 2050 compared to 2012. Although TKA is successful in reducing knee pain and joint stiffness in most cases, it can be associated with a 7-35% incidence of persistent refractory post-surgical knee pain.
