To evaluate the effect of abdominal electrical stimulation (EE) on bowel movement frequency and feces consistency and expelled amount in people with constipation due to spinal cord injuries (SCI).
This is an experimental, crossover, randomized pilot study with two treatment groups: conventional intestinal rehabilitation and conventional rehabilitation associated with EE via 8- and 20-Hz Functional Electrical Stimulation (FES) of the abdominal muscles. Both groups were followed for two weeks with daily 30-minute EE sessions. Participants were hospitalized in a rehabilitation institute in the municipality of São Paulo. Data were analyzed using descriptive and inferential statistics.
This study included 10 people with SCI, of which most were male (70%), with a mean age of 39 years (SD = 16.37). EE, associated with conventional treatment, was more effective in increasing defecation frequency (p = 0.029) and amount of feces expelled (p = 0.031).
Abdominal EE, associated with conventional treatment, helped to increase defecation frequency and amount of feces expelled in people with constipation due to SCI. This pilot study will serve as the basis for a future clinical trial with greater sampling and statistical evidence.
评估腹部电刺激（EE）对脊髓损伤（SCI）相关便秘患者的排便频率、粪便稠度和排出量的影响。
这是一项实验性、交叉、随机的初步研究，有两个治疗组：常规肠道康复和常规康复联合 8Hz 和 20Hz 腹部肌肉功能性电刺激（FES）的 EE。两组均接受为期两周的每日 30 分钟 EE 治疗。参与者在圣保罗市的一家康复机构住院。使用描述性和推断性统计分析数据。
本研究纳入了 10 名 SCI 患者，其中大多数为男性（70%），平均年龄为 39 岁（SD=16.37）。与常规治疗联合的 EE 更有效地增加了排便频率（p=0.029）和粪便排出量（p=0.031）。
与常规治疗联合的腹部 EE 有助于增加 SCI 相关便秘患者的排便频率和粪便排出量。这项初步研究将为未来的临床试验提供依据，包括更大的样本量和更强的统计学证据。
