ABSTRACT

OBJECTIVE: To evaluate the effects of analgesia by sacral surface electrical stimulation on lower abdominal pain in women with primary dysmenorrhoea. DESIGN: Explorative study. PARTICIPANTS: Eleven female university students, who regularly experience difficulty in their university work due to menstrual pain, or who use analgesics for more than one day each month, were recruited. METHODS: Sacral surface electrical stimulation, 5 Hz for 15 min, was performed after the onset of menstruation. Electrodes were placed on the skin, directly above the second and fourth sacral foramina. Visual analogue scale and degree of pain (calculated by using a low current to assess pain) were determined before and after electrical stimulation. RESULTS: Visual analogue scale score and degree of pain decreased significantly immediately after electrical stimulation (p < 0.001). A correlation was observed between visual analogue scale score and degree of pain before and after electrical stimulation (r=0.516, p <0.001). No side-effects were observed in any participant. CONCLUSION: Sacral surface electrical stimulation may provide immediate pain relief in women with dysmenorrhoea and lower abdominal pain.

ABSTRACT

OBJECTIVE: We examined the toe flexor strength, foot morphology, and falls in community-dwelling elderly women who could walk outdoors independently without aids. METHODS: The presence or absence of falls in 1 year, the toe flexor strength, and foot morphology were recorded in 70 women. Hallux valgus was defined as a first phalangeal angle ≥16°. Falls were compared based on the presence or absence of hallux valgus using the chi-squared test. The toe flexor strength, arch height ratio (medial longitudinal arch), and spread ratio (lateral arch) were compared using the Mann-Whitney U-test according to the presence or absence of hallux valgus. Spearman's correlation coefficient was used to compare toe flexor strength and foot morphology. RESULTS: No difference in the fall rate was noted between those with hallux valgus on at least one foot and those without hallux valgus. No difference in toe flexor strength was noted between feet with and without hallux valgus. Correlations were found between the hallux valgus angle and the arch height (r=-0.228, P<0.01) and spread ratios (r=0.494, P<0.001). CONCLUSIONS: Among community-dwelling elderly women who can walk independently outdoors without aids, the presence or absence of hallux valgus does not affect the incidence of falls. The lack of correlation between toe flexor strength and foot morphology may support this conclusion.

ABSTRACT

The aim of the study was to investigate the effect of cathodal transcranial direct current stimulation to the supplementary motor area to inhibit involuntary movements of a child. An 8-year-old boy who developed hypoxic encephalopathy after asphyxia at the age of 2 had difficulty in remaining standing without support because of involuntary movements. He was instructed to remain standing with his plastic ankle-foot orthosis for 10 s at three time points by leaning forward with his forearms on a desk. He received cathodal or sham transcranial direct current stimulation to the supplementary motor area at 1 mA for 10 min. Involuntary movements during standing were measured using an accelerometer attached to his forehead. The low-frequency power of involuntary movements during cathodal transcranial direct current stimulation significantly decreased compared with that during sham stimulation. No adverse effects were observed. Involuntary movement reduction by cathodal stimulation to supplementary motor areas suggests that stimulations modulated the corticobasal ganglia motor circuit. Cathodal stimulation to supplementary motor areas may be effective for reducing involuntary movements and may be safely applied to children with movement disorders.
