| Summary: | ObjectiveTo observe the correlation between oxyhemoglobin (HbO<sub>2</sub>) concentration changes and brain region activation under different treatment methods using functional near-infrared (fNIRS), providing objective evaluation indicators and analysis basis for the clinical research of postpartum pelvic floor rehabilitation.MethodsA total of 40 patients with postpartum pelvic floor dysfunction (PFD) treated at Dushu Lake Hospital Affiliated to Soochow University from January to June 2023 were selected and randomly divided into 4 groups: pure Kegel group, electrical stimulation group, magnetic stimulation group, and electromagnetic combination group, with 10 cases in each group. The pure Kegel group performed Kegel training for 30 minutes each time, 3 times a week; the electrical stimulation group received biofeedback electrical stimulation for 20 minutes each time, with a frequency of 5-50 Hz, and 5 minutes of Kegel training before and after each treatment; the magnetic stimulation group received pelvic floor magnetic stimulation for 20 minutes each time, and 5 minutes of Kegel training before and after each treatment; the electromagnetic combination group received alternating electrical stimulation and pelvic floor magnetic stimulation treatment for 20 minutes each time, and 5 minutes of Kegel training before and after each treatment. All four groups were treated for one course of 10 sessions. Before and after treatment, pelvic floor prolapse was assessed by pelvic floor anatomy indicators, surface electromyographic values of the pelvic floor muscles were assessed by EMG, and HbO<sub>2</sub> concentration changes and activation in different brain regions were observed using fNIRS.ResultsAfter treatment, the mobility of bladder neck in the pure Kegel group improved compared with that before treatment (<italic>P</italic><0.05), and the urethral rotation angle and levator ani fissure area improved to some extent (<italic>P</italic><0.05). The electrical stimulation, magnetic stimulation and electromagnetic combination groups all showed improvements in pelvic floor anatomical indicators compared with those before treatment (<italic>P</italic><0.05), and further inter-group comparison showed that the improvement in the electromagnetic combination group after treatment was significantly better than the other three groups (<italic>P</italic><0.05). After treatment, the surface electromyography ralues of pelvic floor muscle in the pure Kegel group showed significant improvement in pre-resting potential (<italic>P</italic><0.05) and the endurance contraction (<italic>P</italic><0.05) compared to those before treatment. The pre and post resting potentials, and flick, tonic and endurance contractions the surface electromyography ralues of pelvic floor muscle in the electrical stimulation, magnetic stimulation and electromagnetic combination groups all improved (<italic>P</italic><0.05). Further inter-group comparison showed that the the surface electromyography ralues of pelvic floor muscle in magnetic stimulation group showed better improvements in pre-rest and post-rest stages than the pure Kegel group and the electrical stimulation group (<italic>P</italic><0.05). The improvement of flick contraction, tonic contraction and endurance contraction the surface electromyography ralues of pelvic floor muscle in the electromagnetic combination group was better than that in the other three groups (<italic>P</italic><0.05). Compared with that before treatment, the oxygen concentration of HbO<sub>2</sub> in L-PMC regional electrical stimulation group and magnetic stimulation group increased after treatment (<italic>P</italic><0.05). After treatment, the oxygen concentration of HbO<sub>2</sub> in L-PMC regional electromagnetic combination group increased (<italic>P</italic><0.05). The oxygen concentration of HbO<sub>2</sub> in the L-SMC regional magnetic stimulation group increased after treatment (<italic>P</italic><0.05).After treatment, the network efficiency of the electromagnetic combination group increased (<italic>P</italic><0.05). Compared with the electrical stimulation group, the difference of HbO<sub>2</sub> blood oxygen concentration in the R-PMC regional magnetic stimulation group was larger (<italic>P</italic><0.01). Compared with the electrical stimulation group, the difference of HbO<sub>2</sub> blood oxygen concentration in the R-SMC regional electromagnetic combination group was larger (<italic>P</italic><0.05). Compared with the magnetic stimulation group, the difference of network efficiency in the electromagnetic combination group increased (<italic>P</italic><0.05).ConclusionThe electromagnetic combination treatment regimen strengthens the involvement of the right hemisphere, enhances the synergistic efficiency between multiple functional brain regions, and is more conducive to enhancing pelvic floor contractility and reducing pelvic floor anatomical abnormalities. Clinically, it is recommended to use electromagnetic stimulation treatment more often, which contributes to the brain functional connectivity in the motor area. |
