Effect of Sensorimotor Training on Upper Extremity in Parkinson's Patients

There are many factors affecting the upper extremity such as tremor, bradykinesia, rigidity, and postural instability in Parkinson's patients. According to the International Classification of Functioning, Disability and Health (ICF) model, there are restrictions on people's activities and participation in life due to structural and functional disorders affecting the upper extremity in PD.

In PD, integrating and using proprioceptive feedback, sensorimotor integration and peripheral sensory functions are reported to be impaired. Numerous studies show that the main source of motor problems in PD is dysfunction of sensorimotor integration. Since the cervical region contains a dense concentration of proprioceptive organs such as muscle spindles, it plays an important role in providing afferent proprioceptive information for postural control. Therefore, sensorimotor training targeting the cervical region gains importance. In this study, we aim to reduce PD-specific upper extremity disorders and related activity and participation limitations by increasing motor control in the cervical region with sensorimotor training. Patients with Parkinson's disease will be included in the study and randomly divided into 2 groups. While the general physiotherapy program will be applied to the control group, sensorimotor training will be given in addition to the exercise group.

Treatment and study plan

Control Group

Other

Treatment protocol; It will be applied to improve posture, strengthen muscles, eliminate shortness, increase flexibility, balance/coordination, sit up/stand up and in-bed mobilization, and improve gait. Before taking the treatment, a general evaluation will be made and as a result of this evaluation, muscle shortness, loss of strength, postural disorders and the activities and positions they have the most difficulty in daily life will be determined. Treatment programs will be shaped according to the problems determined in line with the evaluations made.

Exercises Group

Other

In addition to the standard physiotherapy program, sensorimotor training including the cervical region will be given to the this group. Deep cervical flexor and extensor muscles, which provide stability in the cervical region, will be trained. A Pressure Biofeedback Device will be used to train the deep cervical flexors. Both positional and kinesthetic sensory training will be provided by maintaining the stability of the cervical region by means of the laser kit that provides visual feedback.Additionally, oculomotor exercises will be given.

Primary outcomes

  1. Posture Analysis

    Time frame: Change from baseline at 8 week

    New York Posture Rating Chart

  2. Tremor

    Time frame: Change from baseline at 8 week

    Fahn; Tolosa, Marin Clinical Tremor Rating Scale will be used to evaluate tremor. Each item was scored between 0-4. A lower score is an indicator of better status.

  3. Unified Parkinson's Disease Rating Scale

    Time frame: Change from baseline at 8 week

    Unified Parkinson's Disease Rating Scale is a scale that evaluates disability and disorders related to Parkinson's and consists of 4 main subtitles and 42 questions in total . Each item was scored between 0-4 . A lower score is an indicator of better status.

  4. Proprioception

    Time frame: Change from baseline at 8 week

    For proprioception, joint position error in the cervical region and upper extremity will be evaluated with the laser kit.

  5. Tactile acuity

    Time frame: Change from baseline at 8 week

    For upper extremity tactile acuity, moving 2-point discrimination test (MTPD) will be performed using an esthesiometer.

  6. Touch threshold

    Time frame: Change from baseline at 8 week

    Semmes Weinstein Monofilament Test will be used to evaluate upper extremity touch threshold.

  7. Pain threshold

    Time frame: Change from baseline at 8 week

    Algometer will be used to evaluate upper extremity pain threshold.

  8. Pain intensity

    Time frame: Change from baseline at 8 week

    Visual pain scale (VAS) will be used to evaluate upper extremity pain.In the evaluation, pain averages ranging from 0 to 10 cm are given. "0" indicates that there is no pain, while as the score increases, the severity of pain increases.

  9. Hand Grip Strength

    Time frame: Change from baseline at 8 week

    Hand Dynamometer will be used to measure hand grip strength.

  10. Pinch Grip Strength

    Time frame: Change from baseline at 8 week

    Pinch meter will be used to measure pinch grip strength.

  11. Endurance of Cervical Muscles

    Time frame: Change from baseline at 8 week

    Craniocervical Flexion (CSF) test, Evaluation of cervical flexor-extensor muscles

  12. Fatigue

    Time frame: Change from baseline at 8 week

    Parkinson's Fatigue Scale will be used to evaluate fatigue. It is consists of 16 items related to presence of fatigue. All items are scored by patients using a five-point Likert-type scale including response options ranging from '(1) strongly disagree' to '(5) strongly agree'. A higher score indicates a higher level of fatigue.

  13. Hand functions

    Time frame: Change from baseline at 8 week

    Purdue Pegboard Test (PPT)

  14. Dual Task Performance

    Time frame: Change from baseline at 8 week

    During the Purdue Pegboard Test, the second task will be added and the completion time will be recorded.

  15. Disabilities of the Arm, Shoulder and Hand Questionnaire

    Time frame: Change from baseline at 8 week

    It will be used to determine the problems experienced in the use of the upper extremity. It consists of 3 sections. All questions are answered according to a 5-point Likert system. A score between 0-100 is obtained from each section. The higher the score, the higher the disability.

  16. Quality of life evaluation

    Time frame: Change from baseline at 8 week

    Parkinson's Disease Questionnaire (PDQ-39) will be used to evaluate quality of life. It contains 39 items in total. A score between 0 and 4 is given for each question. A high overall score indicates worsening quality of life.

  17. Evaluation of Environmental Factors

    Time frame: Change from baseline at 8 week

    Questions structured by the researchers will be used on the issues of support and attitudes under the environmental factors heading of the ICF model. Questions are scored between 0 and 10. A high score indicates high satisfaction.
