Background: Foot problems are prevalent in older adults, which may increase the risk and concern for falls. Ankle-foot orthoses (AFO) have been shown to be effective in the stabilization of lower extremities, but their long-term effectiveness in improving balance and their potential to encourage older adults to become more physically active are still debated. Objective: This randomized controlled trial investigated the effectiveness of daily use of a custom-made AFO on balance, fear of falling, and physical activity in older adults. Study Design: Forty-four older adults with concern about or at risk for falling were randomly allocated to either the control group (CG; 77.3% female, age 75.6 ± 6.5 years, BMI 29.3 ± 6.4) or the intervention group (IG; 63.6% female, age 73.7 ± 6.3 years, BMI = 27.8 ± 4.8). The IG received walking shoes and bilateral custom-made AFO. The CG received only walking shoes. At the baseline and 6-month follow-ups, balance and physical activity were assessed using validated wearable instrumentation and fear of falling was assessed using the Fall Efficacy Scale-International (FES-I). Adherence and acceptability toward wearing the AFO were assessed using self-reported questionnaires at the 6-month follow-up. Results: No significant between-group difference was observed at baseline (p = 0.144–0.882). Compared to baseline and the CG, hip, ankle, and center-of-mass (COM) sways were significantly reduced at the 6-month follow-up in the IG while standing with the feet together during the eyes-open condition (p = 0.005–0.040). Within the IG, the FES-I was reduced significantly (p = 0.036) and there was an increasing trend in the number of walking bouts with a medium effect size (d = 0.52, p = 0.440) compared to baseline. However, there were no significant changes in FES-I and physical activity measures in the CG (p = 0.122–0.894). The reduction in COM sway in the IG was moderately correlated with adherence (r = –0.484, p = 0.047) and strongly correlated with baseline COM sway (r = –0.903, p < 0.001). Conclusion: Results suggest that bilateral custom-made AFO plus walking shoes is effective in improving balance compared to walking shoes alone, and it significantly reduces the fear of falling, with a nonsignificant but noticeable positive trend in physical activity, compared to baseline. The results also suggest that older adults with poor balance at baseline and higher daily adherence to using the AFO will gain more benefit from the AFO intervention.

Background: Ankle-foot orthoses are known to have a generally positive effect on gait in stroke, however the specifc type of AFO and the time point at which it is provided are highly variable in the currently available literature. Objective: The objective was to determine the immediate spatiotemporal and kinematic effect of custom-made solid ankle–foot orthoses in early stroke rehabilitation, compared to shod walking. Methods: Five male and three female participants were recruited to the study ( n = 8), with a mean age of 57 (16) years who were 3.5 (3) weeks post-stroke. Each received a custom-made solid ankle–foot orthosis to a predefined set of design criteria and tuned using heel wedges to control the shank inclination angle during shod walking. Repeated spatiotemporal and three-dimensional gait measures were taken pre- and immediately post-intervention. Study design: A pre–post-test experimental study. Results: With the solid ankle–foot orthosis, walking velocity increased from 0.22 (0.2) to 0.36 (0.3) m/s ( p < 0.05), overall average step length increased from 0.28 (0.1) to 0.37 (0.1) m ( p < 0.05), cadence increased from 45 (19) to 56 (19) steps/min ( p < 0.05) and step length symmetry ratio increased from 0.65 (0.2) to 0.74 (0.2) (not significant). No clear changes were observed in the joint kinematics of the hip and knee. Conclusion: In our small group of early stroke patients who were fitted with a solid ankle–foot orthosis, immediate significant improvements occurred in walking speed, step length and cadence, when compared to walking with shoes only. Clinical relevance This study provides evidence about the immediate effects of custom solid ankle–foot orthoses on gait of early stroke survivors. Ankle–foot orthosis design specifications are fully described for replication. This study suggests that observing global segment orientation may be more useful than joint angles when fitting and tuning ankle–foot orthoses for optimal ankle–foot orthosis/footwear alignment.

Objective: To investigate the use of custom-made knee-ankle-foot-orthoses in daily life and differences in usability factors of knee-ankle-foot-orthoses between users and discontinued users. Design: Cross-sectional survey study. Subjects: A total of 163 polio survivors provided with a knee-ankle-foot-orthosis at an outpatient clinic of a university hospital. Methods: Use and usability of knee-ankle-foot-orthoses in daily life were assessed with a postal questionnaire. Usability factors were formulated using the International Organization for Standardization (ISO) 9241-11 standard. Results: A total of 106 respondents (65%) returned the questionnaire. Of these, 98 were eligible for analysis. Seventy-four respondents (76%) reported using their knee-ankle-foot-orthosis. Compared with discontinued users (24%), users experienced more limitations when walking without an orthosis (p = 0.001), were more often experienced with wearing a previous orthosis (p < 0.001) and were more often prescribed with a locked rather than a stance-control knee-ankle-foot-orthosis (p = 0.015). Furthermore, users reported better effectiveness of their knee-ankle-foot-orthosis (p < 0.001), more satisfaction with goals of use and knee-ankle-foot-orthosis-related aspects (p < 0.001). Conclusion: The majority of polio survivors used their custom-made knee-ankle-foot-orthoses in daily life. Factors related to continued use, such as walking ability without orthosis, expectations of the orthosis, previous orthosis experience and type of knee-ankle-foot-orthosis provided, should be considered and discussed when prescribing a knee-ankle-foot-orthosis in polio survivors.

BACKGROUND: Balance impairment is a contributing factor to falls. Falls are a leading cause of injury and death in older adults. An ankle-foot orthosis (AFO) is a device that can be prescribed as an intervention to help individuals with compromised balance to ambulate safely. OBJECTIVE: The purpose of this review was to investigate the role ankle-foot orthoses have in affecting balance in community-dwelling older adults. METHODOLOGY: A scoping review was conducted searching MEDLINE, CINAHL, EMBASE, and REHABDATA databases to obtain the appropriate literature to meet the following criteria: 1) quantitative research design; 2) studies with participants over age 65; 3) studies with participants with drop-foot or sensory deficits in the lower extremity; 4) the treatment intervention was unilateral or bilateral AFOs; 5) the outcome measure was balance or stability. The retrieved articles were assessed based on the internal validity, external validity, objectivity, and reliability of the study design and the interpretation of results.  FINDINGS: 11 articles were identified that met the inclusion criteria. Four major themes emerged in the analysis about the impact that ankle-foot orthoses have on balance in older adults: (1) AFOs improved lateral stability, (2) AFOs improved balance under static conditions, (3) AFOs provided a reduction in postural sway and (4) AFOs increased walking speed in community-dwelling older adults. CONCLUSIONS: The evidence from the findings of the review indicate that ankle-foot orthoses have a generally positive affect on balance in older adults. Clinicians can consider the ankle-foot orthosis an effective intervention that can improve balance in some older adult patient populations. Layman's Abstract Falls are a serious cause of injury and death in older adults over age 65. Poor balance can lead to an increased number of falls in the older population. The use of a brace, called an ankle-foot orthosis, can be prescribed to community living older adults to augment their balance. Ankle-foot orthoses can improve the stability and positioning of the ankle joint and foot to aid in balance during walking and standing, however ankle-foot orthoses have also been found to restrict natural movements and interrupt sensory feedback from the lower leg and foot. The purpose of this article was to investigate how the balance of older adults living in the community is impacted by wearing ankle-foot orthoses. Through conducting a database search to obtain appropriate literature on the topic, four trends were identified for how ankle-foot orthoses impact the balance of older adult wearers. Based on the findings of this review, ankle-foot orthoses were found to improve stability and standing balance, decrease bodily sway, and increase the walking speed of older adult wearers. These findings suggest that ankle-foot orthoses have a largely positive impact on the balance of older adults and can be considered to help improve balance in certain patient populations.

Tone-reducing ankle-foot orthoses (TRAFOs) are said to improve the control and functioning of spastic lower limbs by their biomechanic and neurophysiologic effects. Unfortunately, there is limited evidence in literature to support the theory that TRAFOs can effectively decrease spasticity in the foot and ankle neurophysiologically. The primary purpose of this investigation was to determine the neurophysiologic effect of TRAFOs on soleus muscle reflex excitability in subjects with spasticity following stroke while standing. A repeated-measures intervention study was conducted on 15 adult subjects with stroke who were recruited from the community. Custom-made articulated ankle-foot orthoses (AFOs) and TRAFOs with orthokinetic compression garments (OCGs) were fabricated for each subject. Five conditions were tested: (1) Shoes only, (2) AFO, (3) TRAFO, (4) TRAFO with OCG, (5) shoes only, to determine if the TRAFOs were most effective in decreasing spasticity as assessed by the ratio of maximum Hoffmann reflex amplitude to maximum muscle response amplitude (Hmax:Mmax ratio) of the soleus. The results found that there were no significant treatment effects for the interventions (F = 0.992, df = 2.167, p = 0.388), however, when analysed subject-by-subject, four subjects displayed significant increases in their Hmax:Mmax ratios to at least one treatment condition. Overall, the results demonstrated that the tone-reducing devices had no significant neurophysiologic effect on soleus reflex excitability in subjects with spasticity, however individual responses showed that the TRAFOs increased spasticity in some individuals.
