Detailed Description
Ulnar neuropathy of the elbow is the second most common entrapment neuropathy of the upper extremity. The ulnar nerve is prone to entrapment due to its anatomical location in the elbow. The most important cause of entrapment occurs as a result of frequent chronic mechanical compression or stretching. Repetitive flexion-extension movement of the elbow increases the pressure in both the cubital tunnel and other potential entrapment sites, causing tension in the ulnar nerve and increased intraneural pressure.
Ulnar neuropathy of the elbow, a detailed history and a comprehensive physical examination are the essential first steps in making the correct diagnosis. In case of doubt, electrophysiological studies, in particular, play an important role in diagnosis by determining both the location of nerve compression and the severity of the disease. There are conservative and surgical methods for the treatment of ulnar neuropathy in the elbow. In most patients, especially in mild and moderate entrapments, conservative treatment is preferred instead of surgery as initial treatment.
Low-level laser therapy, one of the physical therapy modalities, creates photochemical reactions and biostimulation in the cells, interstitial tissue, vascular structure and immune system. Its anti-inflammatory effect is through inhibition of Cyclooxygenase-2 enzyme and a decrease in Prostaglandin E2 levels, and its analgesic effect is by inhibiting nociceptive pathways in peripheral nerves, thus reducing pain. It has been shown to increase nerve regeneration and nerve conduction, reduce the effects of nerve compression, and may stimulate nerve healing thanks to its biophysical effect.
There is no sham-controlled study showing the effectiveness of low-level laser therapy in elbow ulnar neuropathy, the second most common entrapment neuropathy. The study was planned to investigate the effectiveness of low-level laser treatment on symptoms, clinical and electrophysiological parameters in elbow ulnar neuropathy.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Low-level laser therapy group
Low-level laser therapy was applied to the patients with the elbow at 45° flexion, creating a total of 5 areas by drawing 2 cm intervals 4 cm below the elbow and 6 cm above the elbow.
The patients in the group used the elbow rest splint throughout the night during the treatment.
|
Low-level laser therapy was applied to each area for 1 minute, with a wavelength of 808 nm and a dose of 2j/cm2 for a total of 5 minutes,10j/cm2 in continuous mode.
A total of 15 sessions were applied 5 days a week for 3 weeks.

Sham Comparator: Sham group
Sham group was applied with a laser probe by the elbow in 45° flexion, creating a total of 5 areas by drawing 2 cm intervals 4 cm below the elbow and 6 cm above the elbow.
The patients in the group used the elbow rest splint throughout the night during the treatment.
|
Sham therapy was applied to each area for 1 minute, with a wavelength of 0 nm and a dose of 0j/cm2 for a total of 5 minutes, 0j/cm2.
A total of 15 sessions were applied 5 days a week for 3 weeks.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Visual Analog Scale (VAS)
Time Frame: Baseline, Days 15 and Months 3
|
The patient's symptoms were filled in, with the VAS score increasing from 0 to 10.
The end of a 10 cm line with 0 cm indicating no complaints (best) and the end with 10 cm indicating very severe complaints (worst).

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hand Grip Strength
Time Frame: Baseline, Days 15 and Months 3
|
The hand is squeezed to grasp with maximum force, with the shoulder in adduction and neutral rotation, the elbow in 90° flexion, the forearm in midrotation and the wrist in neutral.
Jamar hand dynamometer was used in measurements.
Three measurements were written in kilograms (kg), with a one-minute rest between each measurement, and the average value was recorded.
|
Baseline, Days 15 and Months 3
|
Provocative Tests
Time Frame: Baseline, Days 15 and Months 3
|
Tinel's test involves tapping the ulnar nerve in the medial epicondylar groove.
In the elbow flexion test, the elbow is held in maximum flexion, the forearm is in supination, and the wrist is in full extension for 60 seconds.
In the ulnar nerve compression test, the elbow is kept in 20° flexion and the forearm is kept in supination position.
The examiner places his index and middle fingers over the cubital tunnel and applies pressure for 60 seconds.
In all of these tests, if paresthesia or numbness occurs in the ulnar nerve distribution, the test is considered positive.
|
Baseline, Days 15 and Months 3
|
QuickDASH score
Time Frame: Baseline, Days 15 and Months 3
|
Quick-DASH score, which quickly evaluates arm-shoulder-hand problems, consists of 11 questions.
Functional evaluation of the patients' upper extremities and strains during daily living activities are questioned.
The best score in total is determined as 0, and the lowest score is determined as 100.
