The relationship between ambulation capacity, spasticity and piriformis muscle thickness in patients with chronic spinal cord injury: A controlled, clinical and sonographic 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
contextThe main rehabilitation goals for patients with a spinal cord injury (SCI) are to reduce disability, limit impairment, and regain walking ability. Many prognostic factors affect the recovery and ambulation capacity of patients. After SCI, muscles below the lesion level change morphologically.
objectiveAs the muscle thickness is a significant factor for identifying muscle strength, joint functions and joint torque, the aim of this study was to compare piriformis muscle (PM) maximum thickness in patients with incomplete SCI, with those of a sex, age, weight and height-matched control group. Maximum PM thickness was also compared between cases of incomplete and complete SCI in order to estimate whether spasticity and ambulatory status influence PM thickness after incomplete chronic SCI.
methodsThe demographic data, injury characteristics, and clinical findings were recorded for each patient. Muscle thickness was measured using ultrasonography and relationships between PM thickness and demographic and clinical findings were analyzed and compared between the groups.
resultsThe PM thickness of SCI patients was determined to be significantly lower than that of the healthy control subjects. No significant differences were observed in the comparisons of other values between patients with incomplete SCI and the control group.
conclusionSignificant muscle atrophy of the PM is seen in SCI. There is a need for further investigation of the relationship between muscle size and function, and physiological deficits in skeletal muscle and functional ability after SCI.
