Acoustic Radiation Force Impulse (ARFI) Elastography as a diagnostic and monitoring tool for Bell's palsy: A Prospective Study.
Article in Journal of musculoskeletal & neuronal interactions, 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
objectiveTo evaluate ARFI elastography as a diagnostic and monitoring tool in Bell's palsy by comparing affected and unaffected facial muscles, pre- and post-treatment.
methodsThirty patients with Bell's palsy (17 females and 13 males, mean age 44.6 ± 16.76, range:18-72 years) were assessed using Clinical (House-Brackmann grading), electrophysiologic (EMG), and ultrasonographic (ARFI-elastography). In order to assess the diagnostic value of elastosonography, we compared the scores between the paretic and nonparetic sides of the face. Measurements were obtained bilaterally at baseline and after four weeks of physical therapy.
resultsThe initial degree of facial nerve paralysis was 5.13 ± 0.89 on the House-Brackmann scale (range 4-6). This parameter significantly decreased after the treatment, measuring 2.53 ± 0.81. Post-treatment, significant improvements were observed in EMG and ARFI values, particularly in the orbicularis oculi and masseter muscles. No significant correlation was found between EMG and ARFI elastographic parameters.
conclusionsARFI elastography is a promising, non-invasive tool for monitoring Bell's palsy recovery, though standardization is needed.
