Brief Summary

This study, it is aimed to investigate the effectiveness of applied modified constraint-induced movement therapy (MCIMT) with threshold electrical stimulation (TES) in addition to conventional therapy (therapeutic exercise program) in patients with stroke. Before and after the treatment program we will evaluate, the pain level of the participants measured with a visual pain scale; sensory functions with Semmes Weinstein monofilament test battery; muscle tone, and spasticity with the modified Tardieu scale and Digital Palpation Device, which has a very high proof value; functional status with Wolf motor function test and Motor Activity Log; quality of life will be assessed by Stroke Specific Quality of Life Scale. Participants will be included in the study according to the inclusion criteria, the first evaluation of the participants will be made according to the evaluation parameters, and the participants will be randomly distributed into three groups. The first group will be treated with M-CIMT, the second group will be treated with MCIMT with TES for 4 weeks, and the third group will be the control group. A total of 45 participants will be included in the study.

Outcome Measures

Primary Outcomes (8)

• Range of motion (ROM) of upper extremity

  A universal goniometer will be used to evaluate ROM (shoulder flexion and abduction, elbow flexion and extension, wrist flexion and extension and extension of fingers). Kendall-McCreary criteria will be considered in the assessments. Measurements will be repeated three times and the average value will be used in the statistical analysis.

  Change from baseline Range of Motion (ROM) at week 4.

• Pain of upper extremity

  Pain (pain of shoulder, elbow, wrist and fingers) will be evaulated with VAS (Visual Analog Scale). The VAS consists of a 10 cm straight line which presents a continuum of intensity and has verbal anchors at opposite ends representing 'no pain' at the bottom and 'pain as bad as it can be' at the top. The participants will be asked to mark the representing point of their pain levels. The values will be recorded in centimeters.

• Muscle tone and viscoelastic properties of muscle:

  Muscle tone will be evaluated with the Myoton®PRO Digital Palpation Device. It is an evidence-based Class 1 device that evaluates the bio-mechanical properties of soft biological tissues in a non-invasive, objective, reliable, inexpensive, quick and easy way. Myoton® PRO is used in research to evaluate superficial skeletal muscles, connective tissues such as tendons and ligaments, and other soft tissues

  Change from baseline muscle tone at week 4.

• Severity of spasticity

  The Modified Tardieu scale will be used to assess the severity of spasticity. In this method, the severity of spasticity is evaluated at different rates determined. At the joint, the first angle at which the increase in resistance is detected is recorded. The range of motion is compared to the angle at completion. The Stretching Velocities are as follows: V1: As slow as possible (slower than the gravity fall speed of the limb segment) V2: At the rate of gravity fall of the limb V3: As fast as possible (faster than the normal gravity fall speed of the limb).

  Change from baseline severity of spasticity at week 4.

• Superficial sensory function

  The Semmes Weinstein monofilament test battery will be used to evaluate the superficial sense of upper extremity. Monofilaments of varying thickness between 1.65 and 6.65 are used in this test battery. The evaluator applies in order from the smallest filament to the largest filament, the test is stopped when the monofilament is detected by the evaluator. It is a reliable method used in the superficial sensory evaluation of stroke patients.

• Health-Related Quality Of Life

  "Stroke-specific quality of life scale (SSQOL)" will be used to evaluate quality of life. SSQOL; It is a valid and reliable scale consisting of 12 subsections, including energy, family roles, language, mobility, mood, personality, self-care, social roles, thinking, upper extremity function, vision and productivity, and a total of 49 questions. It is graded with Likert-type scoring ranging from 1 to 5.

• Functional Status

  Wolf Motor Function test is used to evaluate upper extremity motor functions. For 15 activities, data is collected in 2 areas, "Functional Skill" and "Performance Time". Using the "Functional Skills Scale", each activity is evaluated between 0-5 points (0= Never used the affected hand during the activity, 5= Normal movement). The average score is calculated for the Functional Skill Scale. Performance Time" is recorded in seconds (sec).

• Motor activity

  Motor activity diary-28 (MAG-28) will be used to evaluate motor activity. The MAG-28 is a valid and reliable scale designed to examine how often and how well a person uses their affected arm outside of the treatment session. It consists of two scales that question how often the patient uses the affected side upper extremity for each activity during daily activities (turning the light switch, opening the door, etc.) (Use Frequency Scale), and if so, how well he or she can perform the activity (Movement Quality Scale). The patient scores himself between 0 and 5 (0 = I do not use my affected arm at all, 5 = I use my affected arm with the same frequency/quality as before the stroke). For the average score, the total scores of both scales are calculated separately and divided by the number of questions

Study Arms (3)

Experimental group-1 (M-CIMT group)

EXPERIMENTAL

participants in this group will be trained with Modified Constraint Induced Therapy (M-CIMT) in addition to conventional therapy. M-CIMT is shorter versions of CIMT. The original CIMT devotes six or more hours for therapy and constraining of the intact arm for 90% of waking hours per day and over a period of two weeks. Researchers have observed that such a schedule of CIMT is exhaustive and possibly resulting in non-compliance. Because of this reason,s Modified shorter versions of CIMT (mCIMT) have been designed by researchers. Duration of M-CIMT interventions varies from 2 to 10 weeks and the treatment time also varies from as short as 30 minutes to three hours per day in various studies. Nevertheless both CIMT and mCIMT have shown promising success. M-CIMT emphasizes massed practice with the affected upper limb.

Other: Modified Constraint Induced Therapy and Threshold Electrical Stimulation

Experimental group-2 (M-CIMT+TES group)

EXPERIMENTAL

participants in this group will be trained with Modified Constraint Induced Therapy (M-CIMT) and threshold electrical stimulation (TES) in addition to conventional therapy. TES is based on low-intensity (\<100 Hz) and long-duration current and is applied with superficial electrodes. TES provides a natural proprioception by depolarizing the sensory and motor nerves without causing any muscle contraction. TES can improve motor learning and motor performance by improving connections between sensory-motor cortical association regions in the brain.

Other: Modified Constraint Induced Therapy and Threshold Electrical Stimulation

Control group

NO INTERVENTION

participants in this group will be trained with conventional therapy. Conventional therapy consists of strength training, stretching exercises and functional activity training.

Interventions

Modified Constraint Induced Therapy and Threshold Electrical Stimulation OTHER

M-CIMT emphasizes massed practice with the affected upper limb with restraining unaffected limb by a mitt. Threshold electrical stimulation is based on low-intensity (\<100 Hz) and long-duration current and is applied with superficial electrodes.
