Purpose

We examined the effects of exercise therapy on postural stability, multifidus thickness, and pain intensity in patients with low-back pain.

Materials and methods

Subjects were divided into a chronic low-back pain (CLBP; n = 10) group and a healthy control (C; n = 10) group. Group CLBP took part in an 8-week training programme, whereas group C did not. The thickness of the multifidus in both groups was assessed using ultrasonography before and after 8 weeks, in prone and kneeling positions, in relaxed and contracted states. A standing heel-raising test was used to assess postural stability.

Results

After the intervention in group CLBP, the thickness of the contracted multifidus increased in the prone position, whereas the thickness of both the contracted and relaxed multifidus decreased in the kneeling position. In group C after 8 weeks, multifidus thickness decreased in both positions, while both relaxed and contracted. Group C performed the standing heel-raising test significantly better than group CLBP before the 8-week period. After the training, group CLBP improved significantly, but no changes were found in group C.

Discussion and conclusions

Changes in thickness of the multifidus correlate with improved postural stability and decreased pain intensity. Decreasing thickness in healthy individuals may be an early sign of developing CLBP.

Sprouts contain minerals, vitamins, and other compounds, which may have antimicrobial activity. Antimicrobial compounds are released from homogenized sprouts and diffuse into the culture medium inhibiting the growth of pathogenic bacteria. These antibacterial compounds may influence the multiplication of contaminating pathogens. In this study the antimicrobial effects of 55 different homogenized sprouts were investigated with agar well diffusion method on human pathogenic bacteria. Homogenizates of different radish, early kohlrabi, and red cabbage sprouts caused inhibitory zone around the wells on the surface of inoculated agar plates. Mustard, zucchini, medical (German) chamomile, spicy fenugreek, and adzuki bean sprouts had antimicrobial effect only against a few human pathogenic bacteria. Twenty-nine other spicy and vegetable sprouts had no antibacterial activity against the investigated human pathogens. The results suggest that a few sprouts have antimicrobial properties, but different cultivars of the same species have different effects against different bacterial strains. The sprouts of radish cultivars contained the most effective antibacterial compounds.

Artificial sweeteners are widely used all over the world. They may assist in weight management, prevention of dental caries, control of blood glucose of diabetics, and also can be used to replace sugar in foods. In the animal experimentation mice were given oral doses of water solutions of table top artificial sweeteners (saccharin, cyclamate based, acesulfame-K based, and aspartame) the amount of maximum Acceptable Daily Intake (ADI) ad libitum. The controls received only tap water with the same drinking conditions as the treated groups. The mice were fed chow ad libitum.We measured food intake and body weight once a week, water and solutions of artificial sweeteners intake twice a week. The data were analysed by statistical methods (T-probe, regression analysis).Consumption of sweeteners resulted in significantly increased body weight; however, the food intake did not change.These results question the effect of non-caloric artificial sweeteners on weight-maintenance or body weight decrease.
