Physical therapists could soon have something new in their toolbox to improve outcomes for survivors of stroke whose gait has been affected, thanks to a $100,000 Magistro Family Foundation Research Grant awarded to a University of Southern California (USC) Division of… Continue reading
Researchers from Korea have developed a new type of AFO that uses neoprene and a novel wire configuration for use with foot drop after stroke. Foot drop can be a sequela of stroke. An ankle–foot orthosis (AFO) is the most widely used method to prevent foot drop in patients with stroke, and is used during weight-bearing training of the limb on the affected side or when there is ankle spasticity or deformity.

A research group from Tohoku University in Japan has developed a new, lightweight and motor-less device to aid stroke patients in their rehabilitation, improving their gait, and preventing falls. The new device can be easily attached to an ankle-foot orthosis (AFO). Continue reading
The Honda Walking Assist Device (HWAD) powered exoskeleton consists of a lumbar frame with motors on both sides to transfer force to the legs via thigh frames. This training device supports walking, based on the inverted pendulum model. Honda has been conducting research on the device since 1999. Continue reading
Stroke often impairs walking, particularly by altering foot clearance during the swing phase. Activity of the tibialis anterior (TA) plays an important role in foot clearance; clinicians often prescribe an ankle-foot orthosis (AFO) for post-stroke patients to help with foot clearance.

Physical therapists with post-stroke clients are invited to participate in Des Moines University (DMU) College of Podiatric Medicine and Surgery’s seventh annual stroke camp on the DMU campus August 20 to 24. Clinicians can earn 4 continuing education contact hours. Continue reading
Spasticity occurs in 20% to 40% of stroke patients. Two new studies add to the body of evidence supporting the use of botulinum toxin type A (BT-A) injections for post-stroke spasticity: the first looked at the ideal timing of injections for plantar flexor spasticity, and the second looked at ultrasound-guided injections for spastic equinovarus.

Canadian researchers have demonstrated that that arm exercises—specifically, cycling the arms—improves post-stroke gait. The authors said this is the first study to test the effect of arm training on post-stroke leg function, even years after the event. The results appear in the Journal of Neurophysiology.

Multiple techniques can help improve gait speed after stroke, from therapeutic exercise to task-specific training to orthotic devices. Despite a growing body of research in this area, however, it is still not clear which intervention is most appropriate for which patients.

Seattle, WA-based Cadence Biomedical in October announced a National Institutes of Health-funded research collaboration with the University of Nebraska-Omaha (UNO) to study stroke survivors’ ability to adapt and… Continue reading
Gait speed improvements associated with 30 weeks of functional electrical stimulation (FES) in poststroke patients are maintained at 42 weeks, according to research presented in June at the 2015 ISPO World Congress. Continue reading
Seattle-based Cadence Biomedical finalized a distribution agreement in April with Ooltewah, TN-based TruMedical Solutions to sell its Kickstart neuro-rehabilitation device across the southeastern US “Stroke Belt” and to national and regional rehabilitation providers. Continue reading
Increasing the plantar flexion resistance of an ankle foot orthosis (AFO) reduces knee hyperextension and changes foot strike pattern during gait in chronic stroke patients, according to research presented in… Continue reading
People who use an ankle foot orthosis (AFO) after a stroke retain significant deficits in neuromuscular function and blood flow many years later, according to research from the University of Oklahoma in Oklahoma City.

Ankle foot orthoses (AFOs) improve self-reported balance confidence and may also improve physical functioning in individuals with chronic poststroke hemiplegia, according to a study published in the April issue of… Continue reading
Chronic stroke patients who can walk independently but retain gait deficits experience greater gains in both walking speed and quality with an overground walking intervention than with body-weight supported treadmill training (BWSTT), according to results of a pilot study epublished by Clinical Rehabilitation in February.
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.

The medical literature suggests that changes in bone density and other bone characteristics after stroke persist after patients have regained ambulatorystatus. Whether ankle foot orthoses have a shielding effect on bone remodeling, however, remains unclear.

Functional balance test scores rise – Use of an ankle foot orthosis (AFO) within six weeks of stroke results in better balance outcomes and earlier independent ambulation than if AFO use is delayed, according to research from the Netherlands.
Tibial bone mineral density in stroke survivors who use ankle foot orthoses (AFOs) remains significantly higher in the unaffected limb than the affected limb after more than a decade, according to research from the University of Oklahoma in Oklahoma City. Continue reading
Gait training on a dual-belt treadmill in an adaptive virtual environment can help improve propulsive impulse in the paretic limbs of individuals with hemiparesis following stroke, according to research from the University of North Carolina at Chapel Hill.
Ankle foot orthoses (AFOs) designed to correct foot drop during swing and provide toe clearance may facilitate more accurate foot placement, according to preliminary data presented in March at the American Academy of Orthotists & Prosthetists annual meeting in Atlanta.
When prescribing an ankle foot orthosis or neuroprosthesis for a patient with acute drop foot following stroke, lower extremity practitioners should consider the device’s potential effects on neural plasticity and motor relearning in addition to its potential effects on gait.

Improving gait and coordination among stroke survivors should involve developing rehabilitation techniques that target abnormal muscle timing characteristics, suggests recent research from the Louis Stokes Cleveland VA Medical Center, OH. The study, e-published in December by Rehabilitation Practice and Research, … Continue reading
Recent research from the Netherlands suggests that a custom-made orthopedic shoe designed for temporary use can enhance early mobilization after stroke, improving functional mobility, walking speed, and gait.
