Abstract
Objectives: Lateral ankle sprain is one of the most common injuries to the musculoskeletal system, especially among active people. This injury causes complex complications, such as recurrent sprain because of reduced postural control. Foot orthoses are among the interventions used to improve postural control in this population. This review aims to investigate foot orthoses to improve postural control among patients with an acute or chronic lateral ankle sprain.
Methods: Four electronic databases (Scopus, PubMed, Web of Sciences, and Google scholar) were searched for experimental studies. Articles were selected using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) method. The articles were reviewed for their quality based on the standards for reporting diagnostic accuracy statements and then entered into this review.
Results: The search results in all databases provided a total of 48 articles. After reviewing the documents, we excluded 38 articles that did not pass the inclusion criteria, resulting in 10 remaining articles. Data extraction from population, interventions, and outcome measures was done for these 10 articles.
Discussion: Foot orthoses are effective in improving the postural control of individuals with an acute or chronic lateral ankle sprain. Considering the existence of mechanical and functional instability, foot orthosis which is made to affect the proprioception and follow the biomechanics of the body seems to be the most effective in this field; however, more studies are required to confirm this

Abstract
Objectives: Among the foot orthoses prescribed to improve postural control in chronic ankle instability, foot orthoses designed to affect both types of mechanical and functional instability have a limited research background. In the present study, a type of foot orthosis named the custom mold with a raised ridge around the perimeter was designed, and manufactured, and its effect on the dynamic posture control of the subjects was investigated.
Methods: This study was a quasi-experimental type in which 30 active young people with chronic ankle instability were selected from sports clubs and divided into two groups. One of these groups used custom mold foot orthoses (CFO) and the other group used custom mold with a raised ridge around the perimeter foot orthoses (CRFO). Dynamic postural control of the participants was evaluated before and after one month with the star excursion balance test (SEBT). A repeated measured statistical test was used to evaluate the obtained data.
Results: Both types of foot orthoses increased the reaching distance of the SEBT, but the result of CRFO was significant in this field, so that after one month in medial (P=0.045), posteromedial (P=0.002), and anteromedial (P˂0.001) directions, significant differences were observed between the two groups.
Discussion: The CRFO can put the subtalar joint in optimal conditions and change the amount of input resulting from the stimulation of the mechanoreceptors in the plantar area of the foot, thus increasing the improvement of dynamic postural control; however, more studies are needed to prove this claim.

Abstract
Objectives: Ankle orthoses are one of the interventions used to prevent first and repeated lateral ankle sprains. We conducted this systematic review of the literature to investigate the effect of ankle orthoses on postural control in individuals with acute, chronic, or functional ankle sprains.
Methods: Three electronic databases (Scopus, PubMed, and Web of Science) were searched for experimental studies using predefined keywords. We used the PRISMA method to select articles. Initially, the articles were examined for inclusion criteria and then assessed for their quality based on the physiotherapy evidence database scale.
Results: In the initial search, we retrieved 156 articles. After following the steps of the PRISMA flowchart and reviewing the entire text, only 14 reports met the inclusion criteria of this study. We extracted data from population, intervention, and outcome measures.
Discussion: Overall, ankle orthoses were effective in improving the static postural control of patients with lateral ankle sprains; however, the dynamic postural control results were unclear. Since most people who experience lateral ankle sprains have both functional and mechanical instability, ankle orthoses may affect both types of instability and thereby improve postural control.

Abstract
Objectives: The focus of patients’ attention during the physiotherapy program has been reported to affect the rehabilitation goals. The study aimed to investigate the effectiveness of an external focus of attention (EFA) on static balance and functional ability in individuals with chronic ankle instability (CAI).
Methods: Fourteen subjects with CAI, aged from 19 to 25 years, were randomly assigned to two groups: external and internal focus of attention (IFA) group. The outcome measures of the study were static balance and functional ability. A pre-intervention evaluation was performed. Following instructions to an external or an IFA, subjects practiced on a balance board 3 times per week for 4 weeks. At the end of each week, they performed evaluation tests, including a time balance test, foot lift test, side hop test, figure-8 test, and star excursion balance test (SEBT). Parametric (mixed analysis of variance) and non-parametric analysis (the Mann–Whitney and Friedman tests) were performed between measurements and groups.
Results: The intervention program showed a statistically significant improvement in static balance and functional ability in both groups. The results indicated the main effect of time (F(2.488, 29.855)=43.880, P<0.001). For the time in balance test, analysis of variance revealed a main effect of time (F(2.571, 30.855)=11.188, P<0.001). Regarding the SEBT, every direction indicated a main effect of time for both groups. No significant differences between the two groups were found in static balance and functional ability.
Discussion: Even though there were no statistically significant differences between the two groups, both types of focus of attention contributed to the improvement of static balance and functional ability, which may reveal an increase in motor control and neuromuscular ability of the subjects with CAI.
