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

backgroundAbdominal spasticity in spinal cord injury (SCI) patients may remain unrecognized, despite its impact on quality of life. CASE PRESENTATION: We report a 47-year-old white Dutch man with incomplete C4 SCI (AIS D) presenting with dyspnea, abdominal pain, and discomfort from involuntary abdominal muscle contractions. Five year post-injury, the patient developed bloating and pronounced abdominal pain, pain in the lower back, and in the intercostal muscles. In addition, a 7-cm diastasis developed in the abdominal midline. These complaints reduced ambulatory capacity and quality of life. Initial management with systemic antispasticity treatment (tolperisone 50 mg, 3×/day) relieved leg spasticity and closed the diastasis, yet failed to alleviate dyspnea. Ultrasound imaging confirmed spasticity predominantly in the internal oblique and transverse abdominal muscles. Given the persistence of abdominal spasticity complaints, we initiated a series of ultrasound-guided botulinum toxin (100-150E incobotulinum toxin-A) injections to the internal and external oblique muscles-with one session also targeting transversus. The injection protocol was refined over successive treatments to achieve an optimal distribution while minimizing side effects on core stability. Although the patient experienced transient balance issues and lower back pain during the initial adjustment period, these effects were minor and resolved within 2-3 weeks.

conclusionsThis case underscores that in ambulatory SCI patients, systemic treatments alone may not sufficiently address abdominal spasticity and concomitant symptoms like dyspnea. Low-dose ultrasound-guided botulinum toxin injections targeting the abdominal muscles can provide significant symptom relief and improve overall functional capacity, offering a safe and effective addition to low-dose systemic treatment.
