Study aim: To assess the effect of one term of stretching exercise on primary dysmenorrhea in high school students. Material and methods: 179 single girls aged 15-17 years with moderate-to-severe primary dysmenorrhea were selected from 6 high schools located in 2 different city zones. The students were non-athletes and volunteered for the study. The participants were randomly divided into 2 groups: an experimental group (n = 124) and a control group (n = 55). In the intervention group, the subjects were requested to complete an active stretching exercise for 8 weeks (3 days per week, 2 times per day, 10 minutes each time) at home. In the pre-test, all of subjects were examined for pain intensity (10-point scale), pain duration, and the use of sedative tablets in 2 continuous menstruation cycles. The posttest was examined 8 weeks later. Results: After 8 weeks, pain intensity was reduced from 7.65 to 4.88, pain duration was decreased from 7.48 to 3.86 hours, and use of sedative tablets was decreased from 1.65 to 0.79 tablets in the experimental group (p<0.05). In the control group, a significant decline was only noted for pain duration (p<0.001). Conclusions: Stretching exercises are effective in reducing pain intensity, pain duration, and the amount of painkillers used by girls with primary dysmenorrhea.

The purpose of this study was to evaluate self-rated musculoskeletal complaints and their association with computer use time in the adolescent population in Lithuania. The cross-sectional study done in 2008–2009 in Lithuania. 1806 students aged 13–18 years from randomly selected schools were questioned (response rate 95.8%). Logistic regression analysis results show that musculoskeletal complaints in adolescence are associated with duration of computer use as related to age and gender. Compared with adolescents using computer <2 hours daily, a statistically significant probability of experiencing back pain was determined for younger boys and girls groups (13–15 years) who reported working on a computer >4 hours (OR=2.36 and OR=2.50, respectively) in older age groups (16–18 years); in girls only the ORs of back pain significantly increased with increased time of computer use. the probability of experiencing the neck-shoulder pain was determined only in girls aged 16–18 years who reported working on a computer 2–4 hours (OR=1.62, p=0.020). Musculoskeletal complaints in adolescence are related to duration of computer use. Increasing the time spent at the computer increased complaints of musculoskeletal pain among Lithuanian adolescents. The main guidelines for prevention point to restriction of time of computer use.
