Acute effect of precise manual tasks on physiological tremor of both upper limbs in young and elderly people.

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
objectivesThe aim of the study was to assess physiological tremor as a result of fatigue related to manual activities, taking into account age, gender and upper limb (dominant and non-dominant). MATERIAL AND
methodsThe study included participants from 2 age groups, 25-35 years and 55-65 years. Work fatigue was induced during a 3-hour (180 min) 2-handed upper limb control task which consisted of 3 stages. The first stage lasted 30 min, the second stage - 60 min (90 min from the beginning of the effort) and the third stage - 90 min (180 min from the beginning of the effort). Measurements of physiological tremor were performed before exercise and at 30 min, 90 min and 180 min of exercise duration. An acceleration measurement set-up for both upper limbs was used to collect tremor time courses. The power spectral density functions of the tremor signals were analyzed.
resultsAmplitude indicators from the frequency range 1-5 Hz and 8-14 Hz were extracted for analysis. The age of the subjects did not significantly affect the parameters of physiological tremor. Amplitude indicators from lower (1-5 Hz) and higher (8-14 Hz) frequencies take lower average values for women. For both indicators, a significant difference was observed in the subsequent measurements. The mean values of both indicators for the non-dominant limb were significantly higher.
conclusionsPhysiological tremor measurement carried out simultaneously for both upper limbs to analyze muscle fatigue during repetitive work can improve the efficiency of assessing the occurrence of fatigue on the job and increase the efficiency of assessing adaptive capabilities.
