Resumen
El texto original del estudio, en el idioma en que se publicó.
Background
Carpal tunnel syndrome (CTS) is a common peripheral nerve disorder of the wrist. Nonsurgical treatments e.g. laser therapy may cause potential beneficial effects.
Aim
To compare the dose dependent effects of low level laser therapy (LLLT) and high intensity laser therapy (HILT) on pain and electrophysiology studies in patients with CTS.
Design
Double-blind randomized controlled trial.
Setting
Outpatient physiotherapy clinic.
Population
Ninety-eight participants with CTS, aged between 20 to 60 years, were randomly assigned to five groups.
Methods
All participants undertook four standard exercises, with one group serving as exercise-only controls. Patients were randomly allocated to either high or low fluence LLLT or high or low fluence HILT received over 5 sessions. All patients were assessed by visual analogue scale, median compound muscle action potential (CMAP) and sensory nerve conduction studies before and 3 weeks after the interventions.
Results
VAS was significantly lower in all groups after 3 weeks (P0.05).
Conclusions
HILT with a power of 1.6 W and low fluence of 8 J/cm2 was superior in reduction of pain and improvement of the median motor nerve electrophysiological studies compared to LLLT and exercise-only control groups.
Clinical rehabilitation impact
LLLT and HILT in conjunction with exercise program are effective in reducing pain and improving median motor nerve conduction studies of the patients with CTS. It seems that high power and low fluence laser therapy is better than LLLT and exercise interventions to treat these patients.
