At 15 days, LLLT with exercises showed significantly greater improvement than ultrasound with exercises in both VAS pain score (4.23±0.69 vs 5.17±1.02, p<0.001) and shoulder abduction ROM (51.63±3.96 vs 44.60±4.88, p<0.001).

Overview

Supports preferring LLLT over ultrasound with exercises for short-term pain and ROM gains in acute subacromial impingement; extends evidence on laser adjuncts in shoulder rehabilitation.

Structured PICO

Does low-level laser therapy with exercises improve pain and range of motion compared to ultrasound therapy with exercises in young adults with acute subacromial impingement syndrome?

P
Population
60 patients aged 18-30 years with acute Subacromial Impingement Syndrome (SAIS) Neer stage I or II, residing in Bangalore.
I
Intervention
Low-level laser therapy (LLLT) of Ga-As (Wavelength 850 nm, Power output 100 mV, Dosage 5 J/cm2) for 5-6 minutes along with shoulder exercises, 5 times per week for 2 weeks.
C
Comparator
Ultrasound therapy (Intensity 0.5-0.8 W/cm2, Pulsed Mode, 3 MHz) for 3-4 minutes along with shoulder exercises, 5 times per week for 2 weeks.
O
Outcome
Pain measured by Visual Analogue Scale (VAS) and active range of motion (ROM) of shoulder abduction measured by Universal Goniometer at 15 days.patient reported

Low-level laser therapy combined with exercises provides greater short-term improvement in pain and shoulder abduction range of motion than ultrasound therapy with exercises in young adults with acute subacromial impingement syndrome.

Limitations

  • Small sample size
  • Prolonged follow-up was not possible due to drop outs
  • Study was done only between 18 to 30 years
  • Study is limited only to NEER stage I & II of SAIS
  • Duration of the study is only 2 weeks
