The role of hip extensor strength during cutting

Although most clinicians tend to emphasize hip abductor and external rotator muscle  strengthening in injury prevention and rehabilitation, recent research suggests exercises to increase explosive hip extensor strength may be critical for controlling frontal plane motion during cutting tasks.

Using wearable sensors to characterize CP gait

Inertial measurement units (IMUs) facilitate the creation of a gait analysis system that is portable and suited for use in the clinic. Research suggests IMUs can be used to measure clinically important gait metrics in children with cerebral palsy, which may improve patient outcomes.

Fluoroquinolones and risk of tendon damage

As ciprofloxacin and other fluoroquino­lones are prescribed more frequently, tendon-related adverse effects are also becoming more common. Experts often do not recommend these drugs, particularly for athletes or elderly patients, and emphasize that all patients should know the risks.

Peroneal tendinopathy management in tennis

Although not as common as Achilles tendinitis, peroneal tendinitis is seen in a certain group of patients with chronic ankle instability or with a cavovarus foot.1 Peroneal tendinitis presents as lateral foot pain and may also be of unknown etiology or associated with an acute inversion injury.

AFO stiffness can help optimize patient function

Decisions related to the stiffness of an ankle foot orthosis (AFO)—whether they involve device design or the materials from which it’s fabricated—can help lower extremity clinicians customize stability, biomechanics, and muscle function to meet individual patients’ needs.

How foot and ankle injury trends reflect today’s NFL

Professional football players are enduring higher levels of force than ever, and foot and ankle injury rates are increasing as a result. Advances in surgery and rehabili­tation have helped get players back on the field more quickly, but injury prevention remains a significant challenge.

Adjacent-joint arthritis after ankle arthrodesis

Altered biomechanics after ankle arthro­desis often increase stress on the adjacent joints in the foot, which can cause or exacerbate osteoarthritic degeneration in those joints. Clinicians and researchers are working to better understand this process and how to minimize patients’ risk.

Psychological aspects of ACL rehabilitation

The ability to identify and treat patients at risk for mental health issues after anterior cruciate ligament (ACL) injury may help improve psychological readiness for reconstructive surgery, attitudes toward postoperative rehabilitation, and successful surgical and rehabilitation outcomes.

Management of athletes with excessive pronation

Pronation is a triplanar movement and is the combination of rearfoot eversion, midfoot abduction, and talocrural dorsiflexion.1 Pronation in normal gait allows flexible, adaptive changes to varying types of terrain; it dissipates ground reaction forces; and encourages lower extremity internal rotation.

Role of bariatric surgery in patients with knee OA

Weight loss following bariatric surgery can have biomechanical and symptomatic benefits for obese patients with knee osteo­arthritis (OA). But it’s less certain whether that weight loss can also reduce the risk of obesity-related complications following total knee arthroplasty.

Crossover consequences of unilateral treatments

The mechanisms underlying the so-called crossover effect—when a unilateral intervention results in bilateral changes—are still unclear, but clinical applications related to lower extremity strengthening, fatigue, and stretching are already being explored by rehabilitation specialists.

Insole research explores postural control effects

A growing body of evidence suggests that foot orthoses may be a helpful addition to other therapies for improving balance and potentially reducing the risk of falls. The findings have been mixed, however, and clinical enthusiasm for this type of insole intervention also varies.

Support for dry needling builds among clinicians

Dry needling is gaining momentum as an alternative therapy for myofascial pain, and is supported by a small but growing body of research as well as anecdotal evidence. But the training and expertise required to perform the procedure has become a topic of debate.

Chronic ankle instability, gait, and muscle activity

New research suggests lower extremity clinicians should consider implementing gait training in combination with targeted strengthening of the peroneus longus and gluteus medius muscles to help restore normal gait patterns in patients with chronic ankle instability.

Reducing postoperative thromboembolism risk

Preventing deep venous thrombosis and pulmonary embolism after lower extremity surgery can involve pharmaceutical therapies or mechanical interventions. The type of prophylaxis used depends on the type of surgery, pre-existing risk factors, and patient preference.

Step-rate manipulation and foot-strike pattern

In distance runners, step-rate manipulation of at least 10% above a runner’s preferred rate may be an effective clinical gait retraining method to decrease the severity of foot inclination angle at heel strike and…

Management of Achilles tendinopathy in runners

Achilles tendinopathy is a common lower extremity injury in athletes as well as nonathletes. The Achilles tendon is often a site of injury in runners and is the second most common running-related musculo­skeletal injury, after medial tibial stress syndrome, with an…

Uneven terrain: Tactics for orthotic-device users

Helping patients manage an orthotic device can be challenging, but doing so in the face of uneven terrain is a balancing act between stability, mobility, and strength. Device adjustments and rehabilitation pro­tocols can help patients avoid asymmetries and reduce the risk of falling.

Foot rotation during gait in patients with knee OA

Rotating the foot in or out during gait is associated with significant decreases in frontal plane knee load during early or late stance, respectively, and can be effective for reducing pain and potentially slowing the progression of…

Understanding turf toe: The role of foot orthoses

Turf toe is a common injury in football players competing on artificial turf, but it also occurs in soccer and baseball players on natural grass and other playing surfaces. Turf toe is a sprain of the capsule of the first metatarsophalangeal (MTP) joint; increasing grades of injury may include…

Lower extremity strength and injury risk in runners

Study findings regarding strengthening interventions in runners with patello­femoral pain syndrome have been inconsis­tent, perhaps because specific subgroups are more responsive than others. Preliminary research suggests high school runners may make up…
