Impact of forearm fatigue on the postural response to an externally initiated, predictable perturbation.
Article in European journal of applied physiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe objective was to examine the impact of non-postural muscle fatigue on anticipatory postural control, during postural perturbations induced by platform translations. The experimental setup investigated the central changes caused by fatigue without the potential confounding influence of peripheral fatigue within the postural muscles.
methodsFatigue induced in forearm muscles by a maximal handgrip contraction has been previously shown to influence forearm force production for 10 min, reduce ankle plantarflexion force for 1 min and create measureable central fatigue for 30 s. The peak-to-peak anterior/posterior displacement of the center of mass and center of pressure (COP) and muscle activity were measured during the postural perturbation tasks performed before the fatigue protocol and for 10 min post-fatigue.
resultsThe fatigue protocol decreased the peak-to-peak COP displacement from 128.0 ± 12.3 mm pre-fatigue to 81.9 ± 7.8 mm post-fatigue during the forwards platform translation (p < 0.05) and from 133.8 ± 12.0 to 89.2 ± 7.9 mm during the backwards translation (p < 0.05). The fatigue protocol also caused the tibialis anterior (TA pre-fatigue = -0.25 ± 0.04 s, TA post-fatigue = -0.41 ± 0.02 s, p = 0.001) and medial gastrocnemius muscles (MG pre-fatigue = -0.39 ± 0.03 s, MG post-fatigue = -0.48 ± 0.02 s, p = 0.028) to be recruited significantly earlier relative to the pre-fatigue condition.
conclusionThis experimental setup ensured that peripheral fatigue did not develop in the postural muscles; therefore, a general fatigued-induced modification of the postural strategy is proposed as the origin of the postural changes and delayed recovery.
