Brief Summary

It is aimed to investigate the immediate effect of vibrotactile stimulation on pain, sense and functionality in patients with lateral epicondylitis.

Detailed Description

Lateral epicondylitis (LE) is a chronic degenerative disease of the attachment site of the extensor tendons to the lateral epicondyle of the humerus. The annual incidence is 1-3% of the world population and is most common between the ages of 30 and 60. Although LE is often called "tennis elbow," a small percentage of patients play tennis. The etiology of the disease is multifactorial, and it is generally thought to be caused by repetitive wrist activities that include gripping, wrist extension, and supination. Most patients recover spontaneously within 1-2 years. However, loss of work capacity is quite common in jobs that require the use of the upper extremity.

The pathophysiology of the disease is currently explained by degenerative mechanisms instead of the idea of inflammatory infiltration. Microtears and tendinosis caused by increased force on the tendon are supported by ultrasonographic examinations. However, currently, pain and functional disability in daily life are explained by sensory changes such as pain pressure threshold, impaired vibration perception and joint position sense rather than tendon structure changes. Clinically, lateral elbow pain results in decreased grip strength and proprioception, and consequently loss of function.

In LE management, the aim is to relieve pain, minimize excessive loads on the arm and restore the patient to optimal daily life activities and former functionality.

While there is insufficient evidence on the effectiveness of surgical interventions in treatment, nonoperative methods are frequently preferred. Patient education, use of splints, medical treatments, biological treatments, physical agents, taping, and manual therapy approaches are frequently used. While conservative treatments remain up-to-date for pain and disability, the most appropriate treatment strategy is controversial.

The use of technology in physiotherapy has been increasing in recent years. In addition to motor movement, the development of sensory skills is also emphasized. On the other hand, vibrotactile stimulation has been reported to contribute to the sensory processing mechanism by causing different activity levels in the brain. There are no studies in the literature investigating the effects of wearable vibration technology on sensory parameters in LE patients. The aim of this study is to investigate the effects of wearable vibrotactile application on pain, sensation and upper extremity function compared to traditional physiotherapy in patients with LE.

Patients diagnosed with LE will be included in the study. Participants will be randomized into two groups. Patients in both groups will receive one session of conventional physiotherapy on the affected extremity. In addition to the intervention group, the use of a wearable vibrotactile device will be provided. Immediate effects will be evaluated before and after the application in both groups.

Primary Outcome Measures
NameTimeMethod
Pain Severityfrom pre-interventional time to post-interventional about 1st hour

A 10 cm visual analog scale (VAS) was used to assess pain intensity. A horizontal 10 cm ruler was used (0 = no pain and 10 = worst pain).

Pressure pain thresholdfrom pre-interventional time to post-interventional about 1st hour

The J tech brand algometer device will be used for the pressure pain threshold measurement. The trigger points will be found by palpation. The person will be told that the device will apply pressure to the trigger point and that they will give the command "stop" when they first feel the pain.

Joint position sensefrom pre-interventional time to post-interventional about 1st hour

Elbow joint position sense will be measured with an inclinometer for 45 and 60 degree flexion target angle. The elbow will be brought to the target angle and they will be asked to memorize the movement by holding it for 10 seconds. Then, they will be asked to bring the target force they learned themselves. The absolute value of the difference between the target value and the last measurements will be taken as the error score.

Secondary Outcome Measures
NameTimeMethod
Hand grip sensitivity levelfrom pre-interventional time to post-interventional about 1st hour

Pneumatic dynamometer will be used for measurement. The individual's maximum grip strength will be measured and half will be taken to determine the target strength. First, the target strength measurement will be made, then the target measurement will be asked to repeat it without seeing the target measurement value. The absolute value of the difference between the targeted value and the measurements will be calculated and recorded as an error score.

Grip Strengthfrom pre-interventional time to post-interventional about 1st hour

Takei Hand Grip Dynamometer will be used to assess painless grip strength. Subjects will be instructed to increase their grip strength and stop if they feel pain or discomfort. Painless grip strength will be measured 3 times with 30 seconds between measurements and an average score will be obtained.

Functional assessment2 weeks

The Turkish version of the Disability Score for the Arm, Shoulder and Hand (DASH) will be used to assess upper extremity physical function. The questionnaire consists of 30 questions. Scores range from 0 to 100. Higher scores indicate lower functionality.
