Total of 50 subjects were selected on the basis of the inclusion and exclusion criteria and were recruited randomly to the 3 groups (A, B, C). Group A (experimental group) received 780 nm low-level laser therapy and stretching exercises. Group B (experimental group) received 904 nm low-level laser therapy and stretching exercises. Group C (controlled group) received only stretching exercises.
Results:
No significant difference in VAS and NDI from 0 to 2nd week in all the 3 groups i.e. Group A, B, and C indicating that rate of improvement in all the 3 groups was the same.
Conclusion:
Present study does not conclude that stretching is an effective intervention as a significant difference in the rate of improvement was found in the group which received Ga-As laser with stretching. Since the duration over which accumulation of rate of improvement took place was small thus it could not produce any significant difference overall at the end. Hence Ga-As LLLT can be used in adjunct with stretching exercises as cost-effective conservative treatment of MTP in levator scapulaemuscle.
