The aim of the biomedical research is to determine the informativeness and prognostic factors of surface electromyography by assessing the probability of recovery of balance and gait parameters in the second stage of rehabilitation of persons with cerebral infarction.
Cerebral infarction for the first time;
Age from 18 to 89 years old;
Muscle strength according to the Oxford scale is 3-5 points;
Able to walk without the help of others;
Muscle strength according to the Oxford scale is 0-2 points;
Unable to walk without the help of others;
Sensorimotor aphasia or other perceptual disorders;
Do not sign the informed consent.
Single group
Gait and balance measurement
DeviceVirtual gait training procedures are included. Balance training procedures with Biodex Balance system are included too.
Muscle strength by Oxford scale
Testing key muscles from the lower extremities (muscle rectus femoris, muscle biceps femoris, muscle gastrocnemius, lateral head, muscle tibialis anterior) against the examiner's resistance and grading the patient's strength on a 0 (No contraction) to 5 (Movement against gravity with full resistance) scale.
Gait analysis with surface electromyography: Load change (seconds)
Time change heel to forefoot.
Gait analysis with surface electromyography: Maximum force (Newton)
The average maximum force change reached in N/cm² for the three zones: toes, mid-foot and heel.
Gait analysis with surface electromyography: Maximum pressure (Newtons /square centimeter (N/cm²))
The average maximum pressure reached in N/cm² for the three zones: toes, mid-foot and heel (left and right legs separately).
Biodex Balance System (BBS): Postural Stability Test (Overall stability index)
The BBS will be used to assess postural performance of participants. The movable platform of the BBS allows up to 20° of surface tilt in anterior-posterior and medial-lateral directions. The device is equipped with computer software (Biodex, version 3.1; Biodex Medical Systems). Platform Setting 8. Test Trial Time 20 secs. A high number is indicative of a lot of motion, which is indicative of the patient having trouble balancing. Change from baseline postural stability by overall stability index.
Biodex Balance System (BBS): Limits of Stability Test (seconds)
During test, patients must shift their weight to move the cursor from the center target to a blinking target and back as quickly and with as little deviation as possible. Platform Setting STATIC. Direction control - OVERALL. Faster - better. Time change of limit of stability test.
Biodex Balance System (BBS): Limits of Stability Test (score)
During test, patients must shift their weight to move the cursor from the center target to a blinking target and back as quickly and with as little deviation as possible. Platform Setting STATIC. Direction control - OVERALL. The goal - 65 scores and more. Score change of limit of stability test.
Biodex Balance System (BBS): A fall risk test (scores)
Test results are compared to age dependent normative data. Scores higher than normative values suggest further assessment. Platform Setting 12-8. Test Trial Time 20 seconds. Direction control - OVERALL. Patient's aged 54-71 years' normative scores are 0.9-3.7 scores, 72-89 years' normative scores are 2-4 scores, 36-53 years' normative scores are 0.7-3.1 scores, 17-35 years' normative scores are 0.7-2.1 scores. Change from baseline a fall risk by scores.
