Effect of Hand Grip Exercise on Rotator Cuff Strength and Shoulder Function Recovery after Arthroscopic Rotator Cuff Repair: A Prospective Randomized Controlled Trial.
Trial report in Clinics in orthopedic surgery, 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
Background: This study aimed to evaluate the effect of hand grip exercise on rotator cuff strength and shoulder function after arthroscopic rotator cuff repair. Methods: Ninety patients who underwent arthroscopic rotator cuff repair were randomly allocated into the grip exercise group (n = 45) and control group (n = 45). The hand grip strengthening exercise (3 sets of 15 repetitions, twice daily) was applied only to the grip exercise group immediately after surgery up to 3 months. From 3 months postoperatively, the same rotator cuff and periscapular muscle strengthening exercises were applied to both groups. The isometric strength of the shoulder joint (abductor, external rotator, and internal rotator) and periscapular muscles, tone and stiffness of the upper trapezius muscle, range of motion (ROM), pain visual analog scale (VAS) score, American Shoulder and Elbow Surgeons score, Constant score, and University of California, Los Angeles score were measured preoperatively and at 3, 6, and 12 months postoperatively. Changes in the supraspinatus muscle atrophy and repair integrity were assessed via magnetic resonance imaging at 6 months postoperatively. Results: At 3 months, abductor, external rotator, and internal rotator muscle strengths were not significantly different between groups, but at 6 months, the grip exercise group showed significantly higher external rotator and internal rotator strengths (all Conclusions: Hand grip exercise affected the rotator cuff and periscapular muscle strengths at 6 months after rotator cuff repair. The grip exercises can effectively and safely promote a faster recovery of shoulder muscle strength and function, without compromising rotator cuff healing.
