Effects of motor imagery in recovery of nerve blockade in patients undergoing total knee replacement under spinal anesthesia: a randomized prospective controlled study.
Trial report in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSpinal anesthesia (SA) is widely used for total knee arthroplasty (TKA) due to its advantages in postoperative pain control and reduced opioid use. However, prolonged motor and sensory blockade remains a concern, delaying recovery and increasing patient discomfort. Given the limitations of current pharmacologic and physical therapy strategies in accelerating neural recovery, motor imagery (MI)-a cognitive technique that activates motor and sensory pathways without physical movement-has emerged as a potential neuromodulatory intervention. This study aimed to evaluate the effects of MI combined with active ankle range of motion (ROM) exercises on neural recovery after SA.
methodsIn this prospective, randomized controlled trial, 76 female patients undergoing TKA under SA were enrolled and allocated to either an MI group (n = 40), who performed structured MI-ROM exercises during their post-anesthesia care unit (PACU) stay, or a non-MI group (n = 36), who received guided relaxation. Motor and sensory recovery were assessed at 30, 60, and 90 min postoperatively using the modified Bromage scale, pinprick test, and alcohol cotton test.
resultsThe MI group demonstrated significantly faster motor recovery at all time points (P = 0.002) and superior sensory recovery via pinprick testing at 60 and 90 min (P = 0.003), while no significant difference was found in alcohol cotton test results (P = 0.314).
conclusionThese findings suggest that MI is a feasible, non-invasive intervention that may enhance early motor and sensory recovery after SA, supporting its potential role in improving postoperative outcomes in TKA patients.
