Abstract

Aim of the study: 1.  Evaluation of the relationship between the change in the stimulation sequence of muscles in the lumbosciatic area and the occurrence of functional pain in the L section of the vertebral column, as compared to the Janda’s model.
2. Analysis of the differences in the superficial electromyography (sEMG) record of a correct and disturbed pattern of muscle recruitment during the prone hip extension test in two sub-groups of patients: suffering from pain (sub-group A) and without pain (sub-group B).
3. Evaluation of the suitability of the sEMG measurement for making diagnoses in patients with pains in the lumbar section of the vertebral column.
The material and method: For the research, 61 persons were qualified, aged 20-35 years, with the average age 25 years (+/- 6). The tested group was divided into two sub-groups. 33 persons were qualified to sub-group A, and to sub-group B (reference group) 28 persons were qualified. Among the participants, a questionnaire was spread, prepared for the needs of the survey, to be filled in. For testing the sequence of stimulations, the measurements were used which had been obtained from the sEMG record during the Prone Hip Extension (PHE )Test.
Results: The results obtained during the examination of the muscles recruitment pattern in PHE test showed a changed sequence of muscles activation in the Patients from sub-group A vs. these from sub-group B. The results of chi-square test (χ²) confirmed the statistically significant dependence: the persons with pain symptoms in the lumbar spine statistically less frequently showed the correct sequence of muscles engagement:  χ²=5.05,  p=0.041, R= – 0.59 (strong negative dependence).
Conclusions: Changes in the pattern of muscles recruitment during the hip joint extension lead to overloads in the lumbosciatic area, consequently causing pain in the lumbar section. Superficial electromyography, because of the possibility of obtaining the quantitative outcome, is a useful method of evaluating muscles performance.

M. Krzyżanowski, R. Hansdorfer-Korzon, E. Rajkowska-Labon – The physiotherapeutic estimation of the act of temporal-mandibular joints among students of Medical University of Gdańsk. FP 2014; 14(4); 14-22

Abstract

Aim of the study. 1. Evaluating the activity of temporomandibular joints manifesting features of dysfunction in students of the Medical University Gdańsk, 2. Quantitative analysis of the disorders occurring in temporomandibular joints. 3. Proving the correlation between the investigated parameters and the analysed dysfunctions in temporomandibular joints
The materials and research method. For the examination, 40 students in the age of 19 to 27 years (21 women and 19 men) were classified, representing the average age of 23 years.  For the needs of this study, a card of patient examination had been constructed. The evaluation covered, among others, such parameters as: the mobility range of the jaw, the Rozencwaig’s dyskinesia index, the movement of the joint head during the jaw abduction, acoustic symptom, pain index, the presence of trigger points, the cervical spine mobility range.  The obtained results were subjected to statistical analysis with the application of Statistica 10 software .
Results. Analysis of the investigated parameters revealed that dysfunctions of mobility range, at least in one direction, occur in 87,5% (n=35) of the examined persons. The Rozencwaig’s dyskinesia index was proven in 37,5% (n=15). Asymmetric movement of the joints heads occurred in 67,5% (n=27) of the examined persons; and the disorders of the jaw guiding track and the presence of the acoustic symptom were revealed in 80% (n=32) out of the total 40 of the examined persons. Among 57,5% (n=23) of the examined, the presence of trigger points was revealed within the masseter and the temporalis muscles, or in one of them. Dysfunction of the temporomandibular joints correlates, among others, with a reduction of the mobility range in the cervical spine, with acoustic symptoms and presence of parafunctions.
Conclusions. A significant percentage of the temporomandibular joints dysfunctions was observed among students. Attention was attracted by the high percentage of people performing parafunctions. Correlations statistically significant for the temporomandibular joints were proven.
