About

Carpal tunnel syndrome is considered to be the most common entrapment neuropathy. Conservative treatment is recommended in the mild and moderate stage of CTS. The aim of this trial is to evaluate the effectiveness of physical therapy modalities in carpal tunnel syndrome.

Full description

Conservative treatment is recommended in the mild and moderate stage of CTS and should involve splinting, steroid injections, oral steroids and ultrasounds .

However, the results of some research studies have showed the beneficial effect of photobiomodulation as well as nerve and tendon gliding exercises in non-operative treatment .

Patients were divided into two groups. The one group received low-level laser therapy (LLLT); the other group underwent ultrasound treatment. Additionally, nerve and gliding exercises were administered in both groups.

The purpose of this trial is to assess the therapeutic efficacy of ultrasound treatment and low-level laser therapy combined with nerve and tendon gliding exercises and to compare the two regimens.

70 participants in 2 patient groups

Group with low-level laser treatment

Experimental group

Description:

The group received low-level laser therapy (LLLT). The application of a GaAlAs infrared laser with a pencil probe (BTL 5000 Combi, United Kingdom; at 830 nm, 9J/cm2 per point, power output of 100 mW, beam diameter of 5 mm) was performed at five points along the median nerve on the palmar side of the wrist 7. The time of exposure was 10 minutes (2 minutes per point). Both the patient and the therapist wore protective glasses during every session.A total of 10 therapeutic sessions were performed during a period of two weeks (five session times per week). Additionally, nerve and gliding exercises were administered.

Treatment:

Other: Low-level laser therapy

Group with ultrasound treament

Active Comparator group

Description:

The group underwent ultrasound treatment. Ultrasound treatment was administered at a frequency of 1 MHz, intensity of 1 W/cm2 ,pulsed mode duty cycle of 1:4 and with a handhold transducer of 5 cm2 (BTL 5000 Combi, UK). The time of application was 6 minutes over the area of the carpal tunnel. Aquasonic gel was used as a couplant. A total of 10 therapeutic sessions were performed during a period of two weeks (five session times per week). Additionally, nerve and gliding exercises were administered.

Other: Ultrasound treatment
