Brief Summary
Carpal tunnel syndrome (CTS) is a chronic compression of the median nerve, which can lead to symptoms such as nocturnal pain and paresthesia in the area innervated by the median nerve. The affected patients also describe discomfort and hypoesthesia in the nerve supply area. Due to the COVID (Coronavirus disease) pandemic, CTS operations have been postponed and delayed. A promising and safe alternative for improving CTS-related symptoms appears to be non-invasive, non-thermal low-level-laser therapy. As a possible conservative, alternative method, low-level-laser therapy has the potential to enable patients with CTS to improve their disease-related symptoms or at least to alleviate the symptoms until the indicated CTS operation (carpal tunnel release). The aim of this randomized, single-blind, placebo-controlled clinical trial is to investigate the influence of 3 weeks of low-level-laser therapy on the symptoms typical of CTS in patients with surgery-indicated carpal tunnel syndrome and its influence on quality of life.

Outcome Measures
Primary Outcomes (6)
Pain: at rest (Numerical Rating Scale for Pain, NRS)
Pain at rest (NRS), scale 0-10, higher score indicates worse pain
baseline, after 3 weeks, after 6 weeks
Pain:movement pain (Numerical Rating Scale for Pain, NRS)
Pain at activity (NRS), scale 0-10, higher score indicates worse pain
baseline, after 3 weeks, after 6 weeks
Pain: Night pain (Numerical Rating Scale for Pain, NRS)
Pain over night (NRS), scale 0-10, higher score indicates worse pain
baseline, after 3 weeks, after 6 weeks
Health-related quality of ife (SF-36 )
Health-related quality of life assessed by SF-36 questionnaire, scores 0-100 for each SF-36 subdomains (out of eight subdomains), higher scores indicates better qualitiy of life
baseline, after 3 weeks, after 6 weeks
Hand function (Quick-DASH)
Hand function assessed by Quick-DASH (Disabilities of Arm, Shoulder and Hand) questionnaire, 19-95, lower scores indicates better hand function
baseline, after 3 weeks, after 6 weeks
Hand function and CTS severity (Boston CTS Syndrome Questionnaire)
Hand function and CTS severity assessed by Boston CTS Syndrome Questionnaire (BCTQ)), score range 19 - 95, a higher score indicates lower hand function and more severe CTS symptoms
baseline, after 3 weeks, after 6 weeks
Secondary Outcomes (9)
Demographic patient data: smoking status
1 day (baseline)
Demographic patient data: previous illnesses
1 day (baseline)
Medication (painkillers / immunosuppressives)
baseline, after 3 weeks, after 6 weeks
Hofmann-Tinel sign (positive / not positive)
baseline, after 3 weeks, after 6 weeks
Phalen test (positive / not positive)
baseline, after 3 weeks, after 6 weeks
- +4 more secondary outcomes

- The patient is capable of giving consent.
- Isolated surgery-induced CTS
- CTS patients with pain (NRS between 2 and 6) and/or paresthesia and/or nocturnal pain that has been present for at least 3 months (pain reported using the "Numerical Rating Scale for Pain" (NRS) between 0 and 10).
- Compliance with 3 weeks of cold light therapy.
You may not qualify if:

- Previous operations in the area innervated by the median nerve or in the area of the affected upper extremity/hand
- CTS recurrence of the affected hand
- Thenar atrophy of the affected hand
- Nerve diseases that affect the upper extremity including the hand (e.g. polyneuropathy)
- Cervical radiculopathy C6/C
