[Use of continuous passive motion in inpatient rehabilitation after shoulder replacement-a retrospective study].

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
backgroundContinuous passive motion (CPM) devices are widely used in the therapy of joint diseases. While the use of CPM after arthroplasty of the knee is already well evaluated, this study focuses on the use of CPM-devices after shoulder arthroplasty.
methodsIn this retrospective analysis, 110 patients were examined for changes in pain perception and use of pain medication. For 45 of them, the development of the active range of motion and the ability to perform the superior and inferior Apley scratch test were investigated after regular CPM treatment as part of a multimodal rehabilitation program following shoulder arthroplasty. Additionally, the potential influence of the initiation time of CPM treatment was statistically analyzed using the Wilcoxon signed-rank test for paired samples and Pearson's rank correlation analysis.
resultsUsing CPM as a component in a rehabilitation treatment concept led to a reduction in pain perception and the need for pain medication. Furthermore, an improvement in the range of motion, was observed. A significant correlation between the timing of the therapy's initiation and the outcome at the end of rehabilitation could not be demonstrated, but the frequency of application correlated positively with changes in the range of motion.
conclusionThe results of this study imply potential for benefits from the use of CPM devices after shoulder replacement surgery as part of rehabilitation. Due to the study design without any control group, a clear distinction between the rehabilitation without intervention, the effect of a multimodal therapy, and the specific effect of CPM therapy is not possible. Furthermore, it is not possible to determine what effect is attributable to CPM therapy and what potential advantages may exist, compared to manual mobilization or purely functional exercises. These questions, as well as aspects of cost-effectiveness, should be investigated in further studies.
