Osteoporosis (OP) –
Patients with spine fractures have chronic pain syndrome and functional limitations, which causes quality of life decrease, possibility of becoming disabled, and makes them continuously appeal for medical help.
Dynamic electroneurostimulation (DENAS) is one of the alternatives to drug therapy of pain, that is because impulse of alternating current is effecting biologically active points and zones, triggers neuro humoral reactions, and anesthetic and anti-
Speaking about patients with osteoporotic spine fractures, there are some indications in a literature that electrostimulation could reduce pain, but there are no evidences of its efficiency .
An evaluation of dynamic electroneurostimulation (DENAS) impact on a pain in a back and quality of life of patients with osteoporotic spine fractures was the purpose of the present research.
Women over 50 years old with osteoporotic spine fractures, which were confirmed with X-
Patients with repeated osteoporosis and spine fractures of different etiology, patients with individual intolerance to electric current, patients with implanted heart pacemaker, patients with neoformations of any kind in the places of electrodes application were not included into research.
33 women with osteoporotic spine fractures (from 1 to 11 vertebra for some persons) and chronic back pain were randomized into 2 groups: main group consisted out of 17 people, control group included 16 people.
Patients of the main group were healed with Denas-PCM-6 apparatus. An application was carried out in the area of thoracic or lumbar spine at the place of the maximal painfulness with the help of remote zonal electrode DENS-
An imitation of DENAS-
Level of DENAS efficiency in therapy of pain syndrome and quality of life change were evaluated with the help of QUALEFFO-
Patients of both groups continued to receive basic therapy of osteoporosis and concomitant diseases without the changes during all the period of the research.
Statistical processing was accomplished with non parametric tests assistance (Wilkokson’s test, Mann-
According to VAS back pain of patients of the main group reduced from 57.5 to 38.5 points; p = 0.003. An uncertain pain reduction from 63.2 to 56.2 points was observed in the control group.
A reliable pain syndrome reduction (from 3.45 to 3.19; p = 0.02) and physical abilities improvement, especially homework (from 2.55 to 2.28; p = 0.01) and mobility (from 2.38 to 2.15; p = 0.001), were received in patients of the main group when having QUALEFFO-
There were no reliable changes on stated indices in the control group.
There were no difference between the main and the placebo group when evaluating everyday activity, general level of health and state of mind.
92 % of patients of the main group and 46 % of patients of the control group (p = 0.02) stated the pain reduction in the thorax when evaluating the pain dynamic. 69 % of patients of the main group and 36 % of patients of the placebo group noticed the pain reduction in the lumbar region, however, statistically significant differences between the groups were not achieved.
Mobility of the spine measuring did not demonstrate any reliable differences neither in main, nor in control group. Walking test demonstrated time reduction both in the main and in the control group.
Number of fybromyalgia points (painful points on the body) decreased after the therapy in all the patients, but the differences are not reliable for the control group, and they are reliable for the basic group (7.58-
Thus, the research confirmed that dynamic electroneurostimulation reduces the pain and improves the quality of life of patients with osteoporotic spine fractures, and it could be included in a complex program of therapy of such patients. It is necessary to continue the research increasing an amount of sampling.
