The purpose of this study was to determine the possibility of clinical application of 2-dimensional motion analysis system to measure spinal range of motion (ROM) in low back pain patients.
Subjects included 10 healthy males and 10 patients with low back pain. Using electronic digital inclinometer and 2-dimensional motion analysis system, thoracic, lumbar, and pelvic ROM was measured for lateral flexion and extension, and thoracic and lumbar ROM was measured for lateral flexion and rotation. Statistical significance was determined in spinal ROM between inclinometer and motion analysis system, low back pain patients and healthy subjects.
There was no significant difference between inclinometer and motion analysis system in each spinal ROM of back pain patients and normal subjects for each motion. Low back pain patients compared to normal subjects showed significantly less each spinal ROM except thoracic and pelvic ROM for extension. When looking at the change of each spinal ROM in respect to time with motion analysis system, low back pain patients took longer from the initiation to the end of each motion, and showed smaller initial change and fluctuation in each spinal ROM during each motion compared to normal subjects.
The results of this study suggest that 2-dimensional motion analysis system can be effectively used for measuring spinal ROM in patients with low back pain.
MYOFASCIAL PAIN SYNDROMES AND EEG-ANALYSIS

Objectives: The subjects were 49 patients who had been diagnosed with myofascial pain syndromes.
Methods: Compressed spectral Furie analysis (CSA) EEG was carried out in all patientS. The electrical activity in cervical monopolar EEG branch of both hemispheres was analysed. The recording was carried on taking into consideration different functional states: 1. weakened awakeness; 2. strained awakeness with varions loadings (verbal and non-verbal).
Results: Unequal paticipation of cerebral structures in causing myofascial pain syndrome was registered in right-side and left-side myofascial pain patients according to the CSA EEG data. The obtained CSA EEG data, firstly, show more significant (selective) role of the right hemisphere in the pain perception mechanism; secondly, lateral periphecal myofascial pain centre hangers (blocks) the reaction of the contralaterae hemisphere to the corresponding loading.
Conclusions: Thus, the left-side pain peripheral centre can become the starting point in the cerebral activity changes in spite of the initial level of EEG activation.
