What is carpal tunnel syndrome?
Carpal tunnel, due to compression of the median nerve at the wrist, may cause numbness, tingling, nighttime waking, and in advanced cases loss of strength, particularly in the thumb, index, and middle fingers. In diagnosis, clinical examination, electrophysiological tests when needed, and concomitant diabetes, thyroid disease, or repetitive wrist loads are important.
How can laser help?
The effects of HILT and photobiomodulation on the perineural inflammatory response, pain transmission, and tissue metabolism have been investigated. The goal is to reduce symptoms and support daily function. Laser does not physically eliminate the anatomical compression in the carpal tunnel.
The role of 980 nm
It can be considered as the primary wavelength due to more appropriate penetration at the wrist and along the median nerve path. A significant portion of the clinical HILT literature is based on NIR wavelengths.
The role of 1470 nm
1470 nm concentrates energy more superficially. It is not recommended as a routine primary wavelength in median nerve compression; if there are superficial accompanying soft tissue targets, it may be used selectively by taking skin temperature into account.
What does the scientific evidence say?
Level of evidence: A-. A meta-analysis dated 2025 reported that HILT may provide benefits in pain, disability, and some nerve conduction parameters. Nevertheless, due to the number of studies, sample sizes, and protocols, the certainty of evidence is limited.
Is laser sufficient on its own?
In most cases, no. Night splinting, ergonomics, median nerve gliding exercises, and evaluation of underlying metabolic factors are important. In advanced nerve damage, options such as surgical decompression should not be delayed.
Our approach in our Bodrum clinic
Our approach in our Bodrum clinic is to distinguish whether the numbness is due to median nerve compression or another issue originating from the neck/peripheral nerves, and then to evaluate 980 nm laser as part of the conservative treatment plan in appropriate patients.
When is a different evaluation needed first?
In cases of thenar muscle atrophy, persistent sensory loss, progressive weakness, or severe electrophysiological damage, further evaluation and decompression options take priority.
Frequently asked questions
Does laser open the nerve in carpal tunnel?
No. Laser does not eliminate anatomical compression; in some patients, it may provide an adjunctive effect on pain, numbness, and function.
Which wavelength is more appropriate?
980 nm is more rational as the primary option. 1470 nm is not a routine primary wavelength due to its more superficial thermal effect.
