The aim of the study is to test the effect of tDCS stimulation on upper and lower limb function in neurological patients and to reduce pain in gynaecological patients. And the impact of tDCS stimulation on patients' quality of life. Standardised questionnaires will be used for pre- and post-stimulation evaluation.
Neurological patients: 1. Main objective: The aim of the study is to see whether the use of tDCS stimulation incorporated into a rehabilitation programme in post-stroke patients and patients with spinal cord and nerve root dysfunction following neurosurgery and non-surgery will improve upper and lower limb function. 2. Specific aim: To test whether the application of 1, 5 or 10 tDCS stimulations is sufficient to achieve improvements in upper and lower limb function, taking into account the dominant limb. 3. Description of the study group The study will include women and men after stroke and spinal cord and nerve root dysfunction admitted for rehabilitation after surgery and not qualified for surgery, as well as healthy subjects. Study participants will be aged between 20-90 years. Post-stroke subjects with spinal cord and nerve root dysfunction will undergo individual rehabilitation using the PNF (Proprioceptive Neuromuscular Facilitation, Polish for proprioceptive neuromuscular facilitation) neurophysiological method performing upper and lower limb patterns. Rehabilitation will last between one and three months. Inclusion criterion: impairments of upper and lower limb function. Exclusion criterion: no written consent to participate in the study. Due to the assessment to be carried out, participants will be divided into groups: * women and men after stroke with and without tDCS stimulation 1, 5 or 10 treatments, * women and men with spinal cord and nerve root disorders after surgery with and without tDCS stimulation 1, 5 or 10 treatments, * women and men with spinal cord and nerve root disorders not qualified for surgery with tDCS stimulation 1.5 or 10 treatments and without, * healthy women and men undergoing all procedures including tDCS stimulation 1.5 or 10 without rehabilitation, * women and healthy men undergoing all procedures without tDCS stimulation and rehabilitation. 4. Methods used in the research: For the purpose of the study to be conducted, the subjects will have an assessment of: * body weight, body height, body composition using the Tanita BC-418 MA device before the start of the study, the subject stands barefoot on the electrodes in the shape of the foot, in his/her hand he/she also grasps the electrodes while being only in underwear and a measurement is taken, body composition indicators like BMI (Body Mass Index), muscle mass, fat mass, lean body mass and water content will be assessed, measured before the start of the study * biomechanical and viscoelastic properties of the skin using the MyotonPRO: during the measurement the subject will be in a standing position, the limbs of the subject will be exposed, the skin of both upper limbs (arm and forearm) and lower limbs (thigh and shank) will be assessed, on the anterior, posterior, lateral and medial sides, measurement before and after the test, * postural stability using the stabilometric platform Coordination, the subject will stand on the platform barefoot only in underwear, upper limbs placed along the torso, measurement will be done with eyes open and closed for a period of 30 seconds, measurement before and after the test, * upper limb reaction time using the Witty SEM Microgate, taking into account the dominant and non-dominant upper limb, the test person will stand in front of special sensors (semaphores) which will display letters and numbers in different colours, when ready the test person will have to find the small green letter 'a' 20 times as fast as possible. The total time of the test will be counted, the test person will be advised to be in comfortable sportswear (not restricting the movement of the upper limbs), the dominant and non-dominant limbs will be evaluated separately, measuring before and after the test, * assessment of the squeezing force of the right and left limb (hand dynamometer), test subjects will be asked to grasp the dynamometer and squeeze their hand with maximum force within 5 seconds. * lower limb reaction time using the Balance Toutor MedTouch platform, the test person will be in comfortable clothing, will be attached by a special harness to the device's extension arm to avoid a possible fall during the test, the test time for one person will last five minutes, the test person will walk on the device's treadmill at a speed of 3 m/s for two minutes, in order to adapt to the walking pace, in front of him/her on a monitor the test subject will see an image of the path in the forest on which he/she is walking in order to divert his/her attention, the device will then elicit a simulated fall reaction in forward, backward and sideways taking into account the test for the dominant and non-dominant lower limb, at the end of the test a record will be obtained for each test subject, recorded by the device in reaction time values, the test will be performed before and after the test, * tDCS Sooma DUO stimulation, the subject will be subjected to neuromodulation of the motor cortex, the treatment will be carried out in the sitting position, the subject will wear a cap with electrodes attached to the head, the treatment time will be 20-30 minutes, the maximum direct current will be 2 mA, the number of treatments will be 1, 5 or 10 (5 or 10 treatments daily from Monday to Friday) in the afternoon. Before and after the neuromodulation, tests will be carried out for the dominant and non-dominant hand: tapping on a tablet for 30 seconds, reflex flop test on a tablet (there will be glowing points that the subject must touch, the shorter the time to touch all the points, the better the score) and nine-hole peg test. In the course of neurostimulation, after 10 minutes the test person will perform mirror therapy, i.e. The subject will then perform mirror therapy, i.e. movements of the dominant hand controlled in the mirror image (wrist extension - 1 minute and 30 seconds pause, wrist flexion - 1 minute and 30 seconds pause, finger flexion and extension - 1 minute and 30 seconds pause, fist clenching and opening - 1 minute and 30 seconds pause, finger inversion and adduction - 1 minute and 30 seconds pause, middle finger tapping - 1 minute and 30 seconds pause, all fingers tapping - 1 minute). Completion of questionnaires, the questionnaires used are: * Roland-Morris disability questionnaire, the questionnaire is completed by the examiner before and after examinations in patients with spinal cord and nerve root disorders, * Barthel scale, a questionnaire to be filled in by the examiner before and after examinations in stroke patients, * ASIA scale classification of spinal cord injuries, questionnaire to be filled in by the examiner before and after examinations in patients with spinal cord and nerve root disorders * Oswestry questionnaire assessment of lumbar spine pain intensity in various activities, questionnaire to be completed by the subject before and after the study, * Neck Disability Index questionnaire for cervical spine pain before and after the study, * Sexual Satisfaction Scale for Women (SSS - W - R15), assessment of satisfaction with current sexual life as well as communication with partner and sexual adjustment, questionnaire to be completed by the subject before and after the study, * male sex life evaluation questionnaire IIEF-5 is filled in by the subject before and after the study, * Katz scale is filled in by the subject before and after the study, * Lawton scale is filled in by the subject before and after the study, * WHOQOL BREF quality of life questionnaire to be completed by the subject before and after the study.
