Resistance is useful: Ankle band activates hip during landing

Wearing a resistance band around the ankles during jump landings is associated with increased hip abduction moments and gluteus medius activation, and may be a more functional alternative to the therapeutic exercises typically used to train the same muscles, according… Continue reading

Out on a limb: In defense of prevention

If athletes knew that decreasing the risk of anterior cruciate ligament (ACL) injury would be accompanied by a slight decrease in athletic performance, how many of them would find that to be a reasonable tradeoff? The findings of a recent study may have lower extremity practitioners asking themselves this question.

Dorsiflexion and knee injury risk: Implications for ankle bracing

Some evidence suggests that, if ankle braces limit athletes’ motion in the sagittal plane, the risk of knee injury could be increased, but other studies have found no association between ankle bracing and knee injury rates. The conflicting findings have made for a clinical conundrum.

Offloading the diabetic foot: Effects of obesity

Increasing body mass index is associated with significantly increased peak plantar pressures regardless of the type of off­loading device used. However, it is possible to decrease plantar pressures in some regions of the foot with the use of offloading devices.

Internal vs external focus: Effects on motor learning

A growing body of research is demonstrating that the focus of actions or movements is critical to how well athletes and patients respond to feedback from instructors or clinicians, and one of the central issues is the distinction between internal focus and external focus.

AFOs and interfaces: The important role of socks

Interface use has long been the subject of study and clinical emphasis in prosthetics, but too little attention has been given to the role of interfaces—padded socks in particular—in protecting the skin and soft tissues from forces experienced during ankle foot orthosis use.

Incline walking: An offloading option for patients with knee OA

Incline walking on a treadmill results in less frontal plane knee loading and more gluteus, hamstrings, quadriceps, and triceps surae muscle activation than level walking, and therefore may benefit patients with knee osteoarthritis or those who have undergone knee replacement.

The Importance of Gross Motor Skills

Early intervention can help provide a solid foundation – Many kids with Down syndrome, autism, and other neurological conditions may experience biomechanical limitations in the form of delayed development of gross motor skills. One of the drivers of that delay can be hypotonia.

AFO tuning: Balancing function and satisfaction

Tuning of ankle foot orthoses (AFOs) and AFO-footwear combinations can significantly improve gait in patients with neuromuscular impairments. Even so, some pa- t­ients still prefer their untuned devices, which has led researchers and clinicians to reexamine their approach to intervention.

Dynamic compression for recovery in athletes

US Olympic Committee researchers have found that peristaltic pulse compression of the lower extremities may provide a means of enhancing the rheological properties of the lower extremities without resorting to extreme temperatures, expensive body work, or stretching.

Prevention of ACL injuries targets youngest athletes

Some evidence suggests that neuromuscular training before puberty can help further reduce anterior cruciate ligament (ACL) injury rates. But young children respond differently to instruction than their older counterparts, which means early intervention requires some creativity.
