1 · What the graph read from it

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.

2 · The registry

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

objectivesMyofascial pain syndrome in the popliteus muscle may change motor control in the affected and related muscles due to changes in proprioceptive and nociceptive afferents, which can exacerbate patellofemoral pain syndrome. The primary purpose of the current study was to explore the electromyographic activity of the local and proximal muscles of the knee joint in patellofemoral pain syndrome accompanied by secondary myofascial pain syndrome specifically affecting the popliteus muscle following dry needling.

methodsMyofascial pain syndrome in the popliteus muscle may change motor control in the affected and related muscles due to changes in proprioceptive and nociceptive afferents, which can exacerbate patellofemoral pain syndrome. The primary purpose of the current study was to explore the electromyographic activity of the local and proximal muscles of the knee joint in patellofemoral pain syndrome accompanied by secondary myofascial pain syndrome specifically affecting the popliteus muscle following dry needling.

resultsDuring step-up, the onset and offset latencies of the local and proximal muscles of the knee joint, except for the offset latency of the gluteus maximus muscle (p-value=0.162), significantly decreased in the intervention group compared to the control group (p-value<0.046). Additionally, there were no significant differences (p-value>0.116) between the groups in the amplitude ratio of the local and proximal muscles of the knee joint during both step-up and step-down.

conclusionsThe present study revealed that dry needling of the popliteus muscle with secondary myofascial pain syndrome associated with patellofemoral pain syndrome constructively modified the local and proximal motor control of the knee joint during step-up.
