Can isokinetic muscle strength training with hip abduction and adduction improve muscle strength, balance, and gait in patients with functional ankle instability? A randomized controlled trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrevious studies have confirmed that patients with functional ankle instability (FAI) have inadequate hip abductor muscle strength. Muscle strength training is a commonly used intervention in people with FAI. The effects investigated by previous studies have shown conflicting results. However, whether hip adduction and abduction isokinetic muscle strength training can improve muscle strength, balance, and gait in patients with FAI remains unclear.
objectiveThe aim of this study was to observe whether muscle strength, balance, Cumberland Ankle Instability Tool (CAIT) score, plantar pressure, and gait can be improved in patients with FAI via isokinetic muscle strength training of the peri-ankle muscle groups combined with hip abduction and adductor muscle groups.
participantsFAI (n=70).
interventionsThe 70 FAI patients were randomly divided into an ankle isokinetic strength training (AIT) group and a hip isokinetic strength training (HIT) group. The AIT group underwent inversion/eversion and dorsiflexion/plantar flexion isokinetic concentric strength training; the HIT group underwent hip abduction and abduction isokinetic strength training based on ankle isokinetic strength training for six weeks.
main outcome measuresBefore and after training, isokinetic concentric force tests around the ankle and hip adduction and abduction, the Star Excursion Balance Test (SEBT), and plantar pressure and gait assessments were performed.
resultsAfter 6 weeks of training, significant changes in muscle strength were observed in ankle inversion, eversion, dorsiflexion, plantarflexion, and abduction for both the AIT and HIT groups (Group*Time, P < 0.05). Furthermore, the HIT group exhibited greater increases in muscle strength compared to the AIT group (Group, P < 0.05). Additionally, both groups showed varying degrees of improvement in dynamic balance, CAIT scores, and gait patterns (Time, P < 0.05), with the HIT group demonstrating superior improvement compared to the AIT group (Group, P < 0.05).
conclusionsIsokinetic strength training through the peri-ankle muscles combined with the hip adductor and abductor muscles was more effective than peri-ankle strength training alone in improving muscle strength, balance, plantar pressure, gait, and self-reported scores in FAI patients.
