Knee flexion after TKA: The significance of squatting

The ability to achieve a 90° squat appears to have important functional implications for patients rehabilitating from total knee arthroplasty. However, detecting impairment may require more rigorous methods than conventional sit-to-stand testing.

Out on a limb: Flop watch

Mark Cuban, the brash billionaire owner of the National Basketball Association’s (NBA) Dallas Mavericks, has pledged $100,000 to fund a study to determine if biomechanical analysis can distinguish legitimate falls during a basketball game from “flops.” The perfectionist in me really likes this idea. But the pragmatist in me wonders whether there might be better uses for that money.

Inserts improve symmetry, velocity in stroke patients

Learned disuse of the affected limb can lead to weight-bearing asymmetries in patients with stroke-related hemiparesis. Compelled body-weight shift therapy, using shoe inserts to force loading of the affected limb, can help patients achieve a more symmetrical gait.

Retraining fixes faulty gait in injured runners

Although the technique is still in its infancy, early research suggests gait retraining can be used to address medial collapse, primarily in runners with patello­femoral pain (PFP) syndrome, and to reduce impact loading in runners with PFP or tibial stress fracture.

Rockers and rollovers: Implications for AFOs

Practitioners and researchers are redefining rocking and rolling as key components of gait, and designing ankle foot orthoses and other orthotic and prosthetic devices to specifically address impairments in the way certain patients rock and roll.

Soft tissue composition and bone injury risk

Documenting how shock propagates through the leg and is attenuated by the soft tissues appears to be a critical step toward advancing practitioners’ and researchers’ understanding of lower extremity injury mechanisms related to running and landing activities.

Relieving pain in patients with diabetic neuropathy

Given the limitations of pharmacotherapy options for treating painful diabetic peripheral neuropathy, practitioners are also considering the merits of cognitive therapy, orthotic management, and combination therapies to relieve patients’ pain.

Minimalist miss: Even over time, gait differs from barefoot

The biomechanical differences between barefoot running and running in minimalist shoes appear to amount to more than just a matter of time.

Altering landing to reduce ACL load may decrease jumping performance

Changes in landing mechanics that are intended to decrease risk of anterior cruciate ligament (ACL) injury may also inadvertently decrease jumping performance in athletes, according to research presented in late May at the annual ACSM meeting.

Kinetic changes postmeniscectomy mimic those associated with knee OA

One to five years after partial medial meniscectomy, young adults demonstrate kinetic alterations associated with knee osteoarthritis (OA), according to research presented in late May at the annual ACSM meeting.
