Wrist muscle performance in students with chronic nonspecific neck pain: an isokinetic assessment.
Observational study in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06240611 (Isokinetic Assessment of Wrist Muscle Performance Among Egyptian Physical Therapy Students With Chronic Non-Specific Neck Pain), which is not on this 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.

Abstract
backgroundWork-related musculoskeletal disorders (WMSDs) are highly prevalent among physiotherapy students and therapists. This high prevalence highlights the specific link between sustained cervical loading which can precipitate nonspecific neck pain and upper extremity dysfunction, clarifying that proximal neck pain may contribute to distal upper extremity impairment. This observational cross section comparative study investigated whether chronic nonspecific neck pain (CNSNP) influences wrist flexor and extensor performance metrics, such as peak torque, average power, total work and work fatigue.
methodsNinety participants (n = 36 females, n = 54 males, age: 18–23) were allocated to either the CNSNP group (n = 44 participants with CNSNP) or the asymptomatic control group (n = 46 participants without CNSNP). A Biodex isokinetic dynamometer operating at an angular velocity of 180°/s was used to measure the endurance parameters of the wrist flexors and extensors.
resultsChronic nonspecific neck pain did not significantly affect wrist muscle performance parameters (peak torque, average power, total work, work fatigue) measured by isokinetic dynamometry at 180°/s (F (1,86) = 1.40, p = 0.241, η²partial = 0.06). While there was no difference in muscle performance across groups, there was a significant difference in flexion and extension movements (F (1,86) = 7.86, p < 0.001, η²partial = 0.27). Wrist flexion peak torque and pain intensity showed a positive correlation (r = 0.47, p = 0.03), but no other significant correlations were found. DISCUSSION AND
conclusionsCNSNP did not significantly impair overall wrist muscle performance in these young physiotherapy students and interns, revealing preserved neuromuscular capacity and movement‑specific modulation of wrist motor control rather than a global loss of force output, clarified by the pain-related increase in wrist flexor peak torque.
