Efficacy of low-level laser therapy combined with exercise for subacromial impingement syndrome: A randomised controlled trial. (2021)

PICO

Patient/Population

Subacromial impingement
syndrome, aged 30-73.

(n=120)

Intervention

  • LASER+Exercise

  • Exercise

  • LASER

Comparison

  • LASER+Exercise

  • Exercise

  • LASER

Outcomes

  • Pain

  • Analgesics intake

  • Shoulder ROM

  • Disability

Translatability:   (3/3) Easy                                    

Comments: “Low-level laser therapy combined with exercises reduce pain intensity, improve shoulder function and reduces pain intensity and medication intake over 3 months.”

Limitations: no control group to assess the natural course of the disease; no group to combined placebo laser therapy with exercise performance.

Appraisals:

PEDro Scale  – (7/10) Blind subjects: No; Blind therapists: No; Intention-to-treat analysis: No. (by PEDro – confirmed)

Intervention – 1

  • LASER (904nm 700Hz)

Dose

  • 3J; 6J/cm2 per irradiation point (9 pints total)  – 27J total session

Periodicity

  • 3 times a week for 8 weeks

Local/Technic:

  • three insertion points each in the supraspinatus muscle tendon, on the subacromial bursa, and along the bicipital groove.  Before exercise.

    Intervention – 2

    • Exercise

    Dose

    • Stretching of each muscle group for 30 seconds, 3 times in a row.
    • 10 sets of 10 seconds of each Isometric exercise.
    • 3 sets of 15 repetitions of each Isotonic muscle strengthening exercise.

    Periodicity

    • 3 times a week for 8 weeks

    Local/Technic:

    AMuscles stretching – trapezius; pectoralis minor; posterior and inferior shoulder structures
    BIsometric/ Isotónic exercises of the scapular pivot, humeral thruster and scapula stabiliser
    1 -(first 6 sessions) – Str etching: A + , Isometric B; in 10 sets of 10 seconds each.
    2 – (next 9 sessions) – Stretching : A + Isotonic B; in 3 sets of 15 repetitions with a 1kg load.
    3 – (last 9 sessions): Stretching A + . Isotonic exercises B; in 3 sets of 15 repetitions with a 1.5kg load.
