Early sleep after action observation and motor imagery improved manual dexterity in patients after surgery for metacarpal and phalangeal fractures.
Trial report in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Immobilization after surgical fixation for metacarpal and phalangeal fractures induces a decay in manual dexterity. Action Observation and Motor Imagery (AOMI) mitigate motor performance decline during hand immobilization, and early sleep after such approaches has been reported to further enhance the consolidation of motor learning in healthy subjects. Here, we investigated the effects of early sleep after AOMI training sessions in subjects with immobilization after surgical fixation for metacarpal and phalangeal fractures. Fifty-four subjects with immobilization of fourth and fifth fingers after fixation of metacarpal and phalangeal fractures were randomized into 3 groups undergoing a 2-week training. AOMI-sleep and AOMI-control groups performed AOMI of transitive manual dexterity tasks between 8:00 and 10:00 p.m. or between 8:00 and 10:00 a.m. respectively, while Control group observed landscape video-clips before sleeping. AOMI-sleep group demonstrated greater manual dexterity improvements than AOMI-control and Control groups at immobilization and training end (T1) and 1-month follow-up (T2). AOMI-sleep group revealed higher active range of motion of fourth and fifth fingers at T1 and T2, and greater hand grip strength at T2 than Control group. These findings suggested that AOMI followed by early sleep during the postoperative immobilization period may improve outcomes of subjects with metacarpal and phalangeal fractures.
