Effects of Ankle-Foot Orthoses on acceleration and energy cost of walking in children and adolescents with cerebral palsy
TLDR
The use of ankle-foot orthoses does affect trunk acceleration that may indicate a beneficial effect on postural control, and using measures of trunk acceleration may contribute to clinical understanding on how the use of orthoses affect posturalcontrol.
Individual stiffness optimization of dorsal leaf spring ankle–foot orthoses in people with calf muscle weakness is superior to standard bodyweight-based recommendations
TLDR
In people with calf muscle weakness, current supplier’s recommendations for the CA7 stiffness level result in the provision of DLS-AFOs that are too stiff and only achieve 80% of the reduction in energy cost achieved with an individual optimized stiffness.
Design principles, manufacturing and evaluation techniques of custom dynamic ankle-foot orthoses: a review study
Ankle-Foot Orthoses (AFO) can be prescribed to allow drop-foot patients to restore a quasi-normal gait pattern. Standard off-the-shelf AFOs are cost-effective solutions to treat most patients with
The Effects of Combining High-Top Shoes with Twister Wrap Orthoses on Balance Parameters of Children with Spastic Diplegic Cerebral Palsy
TLDR
High-top shoes alone and the combination of high-top Shoes with TWO conditions may enhance the stability of children with spastic diplegia more than barefoot.
The Interzonal Distribution of the Load on the Plantar Surface of the Foot During Walking in the Patients with Cerebral Palsy as an Objective Criterion of Functional Impairment Severity
TLDR
It is advisable to use the revealed indicators of roll-over-the-foot impairment in the functional diagnosis of the condition and in assessing the effectiveness of rehabilitation of children with cerebral palsy.
Orthotics lower limbs in children with spastic forms of cerebral palsy: (literature review)
TLDR
World literature review in open electronic databases PubMed and Elibrary for the last 30 years found no articles covering the effectiveness of combined use of several types of orthoses, and further research of the role of orthotics in the medical rehabilitation of children with cerebral palsy appears to be an urgent task.
Increased trunk movements in people with hereditary spastic paraplegia: do these involve balance correcting strategies?
TLDR
An association between increased trunk movements and reduced balance capacity is found, as an increase in trunk movements may partly reflect balance correcting strategies.
Perspectives on assistive technology for improving gait performance of children with Cerebral Palsy in daily-life: requirements,needs and wishes
TLDR
The stakeholders’ needs and criteria reported here may serve as insights for the design of future assistive devices and for the follow-up care of patients with Cerebral Palsy.

The Effects of Varying Ankle Foot Orthosis Stiffness on Gait in Children with Spastic Cerebral Palsy Who Walk with Excessive Knee Flexion
TLDR
The effects of varying AFO stiffness on gait biomechanics and efficiency in children with CP who walk with excessive knee flexion in stance are investigated to suggest that the vAFO stiffness that maximizes gait efficiency is primarily determined by its effect on knee kinematics and kinetics rather than by itsEffect on push-off power.
Rigid Ankle Foot Orthosis Deteriorates Mediolateral Balance Control and Vertical Braking during Gait Initiation
TLDR
The present study examined the effects of wearing an AFO on biomechanical variables and electromyographic activity of tibialis anterior and soleus muscles during gait initiation (GI) and found passively- or actively-powered assistive AFOs could correct for the reduction in muscle activity and enhance balance control during GI of patients.
The influence of the use of ankle-foot orthoses on thorax, spine, and pelvis kinematics during walking in children with cerebral palsy
TLDR
Wearing ankle-foot orthoses not only gives more stability at the pelvis and ankle joint but also influences trunk motion, and it can be concluded that wearing ankle- foot orthoses influences the postural control during walking in children with bilateral spastic cerebral palsy.
Optimising Ankle Foot Orthoses for children with Cerebral Palsy walking with excessive knee flexion to improve their mobility and participation; protocol of the AFO-CP study
TLDR
The AFO-CP trial will be the first experimental study to evaluate the effect of individually optimised FROs on mobility and participation, and include outcome measures at all levels of the International Classification of Functioning, Disability and Health, providing a unique set of data with which to assess relationships between outcome measures.
The efficacy of the floor-reaction ankle-foot orthosis in children with cerebral palsy.
TLDR
The floor-reaction ankle-foot orthosis is effective in restricting sagittal plane ankle motion during the stance phase of gait in patients with cerebral palsy and improvements in knee extension and the sagittal Plane knee extensor moment in stance phase are achieved.
Defining the mechanical properties of a spring-hinged ankle foot orthosis to assess its potential use in children with spastic cerebral palsy.
TLDR
The results suggest that the two stiffest available springs should improve joint kinematics and enhance push-off in children with SCP walking with excessive knee flexion.
Effect of Hinged Ankle-Foot Orthoses on Standing Balance Control in Children with Bilateral Spastic Cerebral Palsy
TLDR
Hinged AFOs for children with CP may be helpful in improving the postural control mechanisms but not the posturally stability in quiet side-by-side standing.
Effect of ankle-foot orthoses on trunk sway and lower limb intersegmental coordination in children with bilateral cerebral palsy.
TLDR
Ankle-foot orthoses affect postural control and intersegmental coordination in children with cerebral palsy and should be taken into account when planning therapeutic management.
