An interventional study of TENS and Conventional rehabilitation in Hemiplegia and Stroke, sponsored by Bezmialem Vakif University. Completed at 1 site in Turkey. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-04-10.

This study evaluates how cross-education (unilateral training) affects muscle strength of the paretic limb in acute stroke patients. Half of the hemiplegic patients will receive conventional treatment and transcutaneous electrical nerve stimulation (TENS) to non-paretic side, while other half will receive conventional treatment and electro muscular stimulation (EMS) to non-paretic side.
Cross-education, which means the performance improvement in the untrained homologous muscle after unilateral exercise training, is studied in various orthopedical and neurological conditions affecting the body unilaterally. For those with asymmetrical weakness and immobility after stroke, training the non-paretic side can be utilized to increase the strength of the paretic side and improve functional symmetry. In this study, investigators aim was to examine whether training non-paretic upper extremity wrist flexor muscles by EMS in adjunct to conventional training program, has additional benefits upon the muscle powers of the homologous agonist and antagonist muscles. Investigators will use low frequency antalgic TENS stimulation at barely sensible level, which is considered not to cause muscle strengthening, as a control intervention.

Exclusion Criteria:
30 sessions (5 sessions/week, 6 weeks) of training including 40 minutes of lower limb training including a mixture of lower limb gait training, balance training and aerobic training and a combination of task-oriented treatment, fine motor skill training, range of motion exercises stretch exercises and strength training (75% repetition maximum (RM), 6 repetitions) for 20 minutes. After that training program, patients will receive 30 minutes of conventional antalgic TENS (100 Hz) program as controls with electrostimulation device to the non-paretic wrist flexors.
Device: TENS · Procedure: Conventional rehabilitation
0 sessions (5 sessions/week, 6 weeks) of training including 40 minutes of lower limb training including a mixture of lower limb gait training, balance training and aerobic training and a combination of task-oriented treatment, fine motor skill training, range of motion exercises stretch exercises and strength training (75% repetition maximum (RM), 6 repetitions) for 20 minutes. After that training, the patients will receive 20 minutes of electrical stimulation to their non-paretic forearm upon wrist flexors by an intermittent maximum strength program (6 seconds of contraction, 10 seconds of rest) along with 5 minutes of pre and post warm-up with the same device.
Procedure: Conventional rehabilitation · Device: EMS

The Fugl-Meyer motor function assessment for upper extremity
This scale is designed to assess reflex activity, volitional activities (within synergies, mixing synergies, with little or no synergy), wrist and hand joint functioning, and coordination of the upper extremity in patients with post-stroke hemiplegia. This scale is an ordinal scale that has 3 points for each item. A zero score is given for the item if the subject cannot do the task. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully. However, reflex activity is measured using 2 points only, with a score of 0 or 2 for absence and presence of reflex respectively. Maximum score in the upper limb is 66 and higher scores represent a better outcome
Time frame: 6 weeks
The functional independence measure
This scale is an assessment tool which evaluate the functional status of patients throughout the rehabilitation process. Degree of disability depends on the patient's score in 18 categories, focusing on motor and cognitive function. Each category or item is rated on a 7-point scale (1 = \<25% independence; total assistance required, 7 = 100% independence. Total score varies between 18 to 126 and higher scores represent a more independent patient
Time frame: 6 weeks
Brunnstrom stage of recovery for hand
This staging evaluates patient according to six sequential stages of recovery as stage 1: flaccidity, 2: basic limb synergy with minimal spasticity, 3: synergy with marked spasticity, 4: limited ability to move normally with reduced spasticity, 5: complex movement combinations, and 6: motor control is almost fully recovered. A patient can plateau at any stage but if able to reach stage 6 he or she makes full recovery
Time frame: 6 weeks
Maximum and mean strength of paretic wrist flexors
While the patient lays in supine on a bad, a physician stabilizes the forearm of the patient and measures the wrist flexion power with a manual muscle tester device while patient's forearm is in supination. This device can measure maximal power and mean power during 10 seconds of pressure. Circular cap of the device is used as application surface and the cap is placed on palm for wrist flexion for measurement. Then the patient is asked to perform a maximum wrist flexion for ten seconds. The device notices the patient for time with two sounds at starting or finishing the measurement. The maximum and mean wrist flexion force, wrist extension force is recorded in kilograms after the measurement.

Maximum and mean strength of paretic wrist extensors
While the patient lays in supine on a bad, a physician stabilizes the forearm of the patient and measures the wrist extension power with a manual muscle tester (Lafayette instrument company, IN, USA) device while patient's forearm is in pronation. This device can measure maximal power and mean power during 10 seconds of pressure. Circular cap of the device is used as application surface and the cap is placed on the middle of hand dorsum for wrist extension measurement. Then the patient is asked to perform a maximum wrist extension for ten seconds. The device notices the patient for time with two sounds at starting or finishing the measurement. The maximum and mean extension flexion force is recorded in kilograms after the measurement
