Unimorph active rigidity joints, constructed from Shape Memory Alloy and Shape Memory Polymer and capable of bending actuation, are reported in this work. An embedded aluminum shim was added to each joint as a structural element to facilitate actuation. Joints were actuated using ohmic Tri-Phase and pulse heating processes with different results. It

Active knee joint flexibility and sports activity
Scandinavian Journal of Medicine & Science in Sports, 1999The aim of the study was to estimate active knee flexion and active knee extension in athletes and to investigate the potential association of each to different types of sports activity. Active knee extension and active knee flexion was measured in 339 athletes.

Athletic Activity after Joint Replacement
The American Journal of Sports Medicine, 2001The first decade of the 21st century has been declared the “Bone and Joint Decade” by 35 nations and 44 states in the United States as of March 2001. It is not surprising that Americans are interested in musculoskeletal disease and the treatment of bone and joint disorders because our population is aging, the prevalence of arthritic joints is ...

Assessing activity in joint replacement patients
The Journal of Arthroplasty, 1998Outcome evaluations of lower extremity joint reconstructions should include an assessment of patient activity. In vivo wear assessments of total joint prostheses should be based on a measure of use, not time in situ or a proxy such as age or gender; however, clinicians lack a simple method to reliably assess the activity of patients with joint ...

Adenosine Deaminase Activity in Joint Effusions
Scandinavian Journal of Rheumatology, 1988The activity of adenosine deaminase (ADA) was determined in serum and synovial fluid of 98 patients with joint effusions of various causes. Compared with osteoarthritis, there were significantly higher mean synovial fluid ADA activities in seropositive rheumatoid arthritis (p less than 0.01), chronic seronegative polyarthritis (p less than 0.001 ...

Athletic Activity After Total Joint Replacement
Orthopedics, 2002Total hip and knee replacement surgery is a successful treatment for the arthritic hip and knee ensuring proven pain relief and return of function. Younger, more active patients who have greater expectations and higher demands are receiving hip and knee replacements. With current surgical techniques and implant designs, athletic participation should be

Athletic Activity After Total Joint Arthroplasty
The Journal of Bone and Joint Surgery-American Volume, 2008Demand for total joint arthroplasty is projected to increase in the first three decades of the twenty-first century. With increasing frequency, patients who have a hip or knee replacement expect to, and choose to, participate in athletics following rehabilitation.
