Functional constipation (FC), which is characterized by conditions such as excessive straining and difficulty in defecation, infrequent bowel movements, and incomplete defecation, is a common bowel disease that causes activity limitation and decrease in quality of life in children and adults, regardless of an organic etiology.~In the literature, there are studies showing the effectiveness of different physiotherapy approaches such as behavioral therapy, exercise, neuromodulation applications, kinesiotape, abdominal massage in FC, and investigate and compare the effectiveness of connective tissue manipulation (CTM) and interferential (IF) current stimulation applied in addition to behavioral therapy and exercise program. But there was any study which compare the effectiveness of these physiotherapy methods with each other and IF current stimulation at different frequencies (100 Hz and 0-100 Hz). In addition, there are no randomized controlled studies comparing the current effects of IF applied at 100 Hz and 0-100 Hz in individuals with FC.~The treatment methods to be applied in this study are behavioral therapy, physical activity and exercise program, CTM and IF current stimulation applied at a frequency of 100 Hz and 0-100 Hz.~The diagnostic method to be used is based on the Rome IV FC Criteria and the Bristol Stool Form Scale.
This study compares the effectiveness of a more comprehensive behavioral treatment, physical activity and exercise program, as well as CTM and IF current stimulation approaches at different frequencies on functional constipation symptoms and quality of life, compared to their counterparts in the literature.
