Effectiveness of Low-level Laser Therapy

Summary

During rotator cuff tear healing stages, there are complex interactions between a variety of tissue growth factors and cells, ultimately resulting in tissue that is markedly different from that of normal, uninjured tendon. Hence, there is a strong drive to investigate the role of potential therapies in the form of biological augments that may restore the pathologic tissue to a near normal physiological state. In this context, low-level laser therapy (LLLT) may be an effective choice in the treatment of nonoperative small and medium-sized rotator cuff tears (RCT). To the best of our knowledge, there is no randomized controlled study investigating the effects of the LLLT in patients with a arthroscopic rotator cuff repair (ARCR). Therefore, the aim of the current study is to investigate all the possible effects of the LLLT in terms of functional status, pain-free mobility, and quality-of-life.

Interventions

OTHER

In addition to the conservative treatment, Low-level laser therapy

For Experimental Group A Gallium-aluminum-arsenide (Ga-Al-As) diode laser instrument (Roland Serie, Elettronica Pagani, Paderno, Italy, Mod IR 27/1) will be used (wavelength 904 nm, 5500 Hz frequency, 27 W maximum power output per pulse, 13.2 mW average power, 0.8-cm2 spot size, 1.6 J of total energy will be delivered per point at each session at a power density of 16.5 mW/cm2, and the cumulative energy per point for all sessions was 16 J). Ga-Al-As laser therapy will be applied to experimental group patients two times per week for 6 weeks in 10-min sessions. LLLT will be applied over the tuberculum majus and minus, the anterior and posterior faces of the capsule, and the subacromial regions. Each point will be treated for 120 sec. The head of the instrument will be held perpendicular to the body surface and in skin contact without pressure.

OTHER

In addition to the conservative treatment, Low-level laser therapy (turned off)

For Placebo Group In the placebo group, laser instrument will be applied in the same way but the device will be turned off during treatment sessions. Patients and physiotherapist will be asked to use protective eyeglasses during therapy for safety.

OTHER

Conservative treatment solely

For Control Group All patients using an immobilization bandage up to post-operative 6th week will receive the standardized 6-week supervised rehabilitation program advocated by the same physiotherapist (CK), 7 years of experience in the clinical treatment of rotator cuff tear, after the baseline assessment. Composed of 30 treatment sessions (five days/week) of 45 to 60 minutes, the rehabilitation program will be provided individually to all participants. Physiotherapy sessions will be devoted to strength, mobilizations, stretching, perturbation, and sensorimotor training using motor control exercises, hence, to restore adequate shoulder neuromuscular control. The treatment program will also be included patient education.
