Task-dependent muscle activation during functional upper-Limb tasks in adults with and without chronic non-specific neck pain: A cross-sectional study.
Observational study in Journal of back and musculoskeletal rehabilitation, 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
BackgroundAlthough many studies explore surface electromyography (sEMG) in static postures, research on muscle activation during dynamic tasks in chronic non-specific neck pain (CNNP) is limited.ObjectivesTo compare trapezius and sternocleidomastoid (SCM) activation and functional capacity during five upper limb tasks between individuals with CNNP and asymptomatic controls.MethodsThis was a cross-sectional comparative observational study. Twenty-seven individuals with CNNP and 25 asymptomatic controls completed five tasks: repetitive reaching (RRT), sustained overhead work (OW), waist-to-overhead lift (OL), fingertip dexterity (FD), and hand-forearm dexterity (HFD). sEMG recorded upper (UT), middle (MT), and lower trapezius (LT), and SCM activity. Functional capacity was assessed using selected WorkWell Systems Functional Capacity Evaluation (WWS-FCE) tasks.ResultsCNNP individuals showed greater UT activation across all tasks (p < 0.01, d = 0.78-1.67) and significant MT differences in most conditions (p < 0.01, d = 0.84-1.44). LT showed smaller but significant differences (p < 0.05, d = 0.47-0.84). SCM activity increased during OL (p < 0.01, d = 0.73-1.08) and in one RRT subtask (p = 0.011, d = 0.73). CNNP performed worse than controls in RRT (p < 0.001, d = -1.32 to -1.61), OW (p < 0.001, d = -2.17), OL (p = 0.006-<0.001, d = -0.80 to -1.26), and HFD (p < 0.001, d = -1.06 to -1.36), with no significant FD differences (p > 0.05).
