Objective We compared gains in range of motion in patients who underwent manipulation within 12 weeks of total knee arthroplasty (TKA) and after this period. We also evaluated maintenance of the arc obtained from knee manipulation in late follow-up, along with factors associated with poorer outcomes. Method The study was divided into two groups according to the time after TKA; the surgeries t...

Arthrofibrosis after total knee arthroplasty (TKA) is a potentially devastating complication, resulting in loss of motion and function and residual pain. For patients in whom aggressive physical therapy and manipulation under anesthesia fail, lysis of adhesions may be the only option to rescue the stiff TKA. The purpose of this study is to report the results of arthroscopic lysis of adhesions a...

Well-organized acute and intermediate rehabilitation after stroke can provide patients with the best functional results. Several studies led to major changes in recommendations concerning remobilization therapies following stroke. Controlled studies including early mobilization in stands and training with partial body weight support on treadmills and "gait training" systems showed superior resu...

Moon, of Dundee, in November 1893. He was then reported to be childish in manner, usually absolutely taciturn, although cheerful and talkative at times ; patellar reflex absent; loss of control of bladder and rectum ; walking and standing steadily ; occasionally sliding off his chair on to the floor with a thump, and remaining stiff; eyes sometimes open, sometimes closed; no spasm. I found him ...

Post-traumatic knee stiffness and loss of range of motion is a common complication of injuries to the knee area. The causes of post-traumatic knee stiffness can be divided into flexion contractures, extension contractures, and combined contractures. Post-traumatic stiffness can be due to the presence of dense intra-articular adhesions and/or fibrotic transformation of peri-articular structures....

1.1 Anatomy and knee joint function The knee joint is classified as a modified hinge joint, with its structure providing a highly mobile and complex joint (fig.1). It consists of two condylar joints between the medial and lateral condyles of the femur and the corresponding plateaus of the tibia, and anteriorly a synovial plane patellofemoral joint. The articular surface of the knee is covered b...

Although leg spring stiffness represents active muscular recruitment of the lower extremity during dynamic tasks such as hopping and running, the joint-specific characteristics comprising the damping portion of this measure, leg impedance, are uncertain. The purpose of this investigation was to assess the relationship between leg impedance and energy absorption at the ankle, knee, and hip durin...

Let a,d be two elements in rings and a∥d the inverse of a along d. When exists, we obtain several characterizations for invertibility aa∥d−a∥da, which is related to expressed by certain functions suitable from center ring. On other hand, some equivalent conditions equality aa∥d=a∥da, as complement previous sense, are given means group inverses ring units, respectively. Then, results obtained ap...
