Comparison of Training Load With/Out Blood Flow Restriction Training in Rheumatoid Populations
Rheumatoid Arthritis, Myositis, Osteoarthritis
About this trial
This is an interventional treatment trial for Rheumatoid Arthritis focused on measuring rheumatoid arthritis, osteoarthritis, myositis, blood flow restriction, strength training, weight training
Eligibility Criteria
Inclusion Criteria:
- diagnosis from LSUHSC-SHreveport Rheumatologist of rheumatoid arthritis (RA), osteoarthritis (OA), or myositis
- stable medication for at least 3 months
- OA in weightbearing joints, and limited to non-advanced OA per Kellgren Lawrence grading
- cleared by rheumatologist for participation in high intensity training and blood flow restriction training
Exclusion Criteria:
- cardiovascular or other disease preventing exercise participation
- within past 6 months, have performed regular physical activity training or physical therapy
- one or more arthroplasty in weight-bearing joints
- taking more then 5mg of prednisone in past 3 months
- unable to perform timed up and go test, 10 meter walk test, or 6 minute walk test without more than supervision assistance; assistive devices can be used

Experimental
Experimental
No Intervention
Traditional High-Intensity Training
Low Intensity plus Blood Flow Restriction Training
Control
Participants will perform their training at ~70% of their 1-repetition maximum, as traditionally advocated in strengthening literature. Each of the diagnoses (RA, OA, myositis) will have a High-Intensity arm.
Participants will perform their training at ~30% of their 1-repetition maximum, and will have blood flow partially occluded (60-70%) to the training limb. Each of the diagnoses (RA, OA, myositis) will have a Low-Intensity plus Blood Flow Restriction arm.
Each of the diagnoses (RA, OA, myositis) will have a control arm. The control groups will be evaluated at time 0, 4 weeks, and 8 weeks but will not receive intervention.
