to better design rehabilitation programs. Therefore, this study examined the effects of fatigue on hip and knee kinematics and kinetics in ACLD patients compared with healthy individuals during single-leg drop landing. We hypothesized the ACLD patients would display different hip and knee

jumping. No current consensus exists regarding the optimal frequency and dosage of augmented feedback. However, more investigations appear warranted. Limitations Despite drop landing being widely used in studies to evaluate kinematics and kinetics that may be related to knee injury, this task may lack
Posttraumatic Ankle Osteoarthritis Alters Stair Ascent and Descent Kinetics
Erik A. Wikstrom, Robert B. Anderson, and Tricia Hubbard-Turner
Those with posttraumatic ankle osteoarthritis have a variety of sensorimotor impairments. However, no investigation has determined the effect of posttraumatic ankle osteoarthritis on stair climbing. The purpose of this study was to determine if stair ascent and descent kinetics are altered in those with posttraumatic ankle osteoarthritis. Those with posttraumatic ankle osteoarthritis had lower self-reported function than age-matched controls. Normalized peak vertical ground reaction forces during the weight acceptance phase of stair ascent and descent were also different between groups. The results suggest that those with ankle osteoarthritis have a reduced ability to control their body mass while stair climbing.
The Effect of Maximalist Running Shoes on Impact Loading: A Critically Appraised Topic

Of interest to this CAT, IP and LR were not different between trials in the different shoes. The researchers found that the participants
Patellar Tendon Straps Decrease Pain and May Alter Lower Extremity Kinetics in Those With Patellar Tendinopathy During Jump Landing
Adam B. Rosen, Jupil Ko, Kathy J. Simpson, and Cathleen N. Brown
Patellar tendinopathy is often managed with a patellar tendon strap, however, their effectiveness is unsubstantiated. The purpose of this study was to determine if straps altered pain or lower extremity kinetics of individuals with patellar tendinopathy during landing. Thirty participants with patellar tendinopathy and 30 controls completed drop jumps with and without patellar tendon straps. Wearing the strap, tendinopathy participants demonstrated significantly decreased pain and reduced knee adductor moment; all participants displayed significantly decreased anterior ground reaction force while wearing a strap. Patellar tendon strapping may reduce pain due to alterations in direction and magnitude of loading.
