Background & Aims
Background: Delayed muscle soreness (DOMS) is a myogenic condition often caused 24 to 72?h after performing exercises that overload the muscles and is not inflammatory in nature. the symptoms of DOMS pain, tenderness alleviate over a period of time but is seen to affect the training schedules of athletes and daily activities of the general population and increases the risk of injuries.
Aim: To study the effect of LASER therapy on pain pressure threshold in individuals with delayed onset muscle soreness (DOMS) in biceps brachii muscle.
Methods
Methods: 68 young healthy individuals aged 18 to 25 years who did not participate in regular exercise were included and DOMS was introduced in the non -dominant arm by performing eccentric contraction of elbow flexors at 75% of 1RM using dumbbell until failure. participants were assessed for pain pressure threshold at 24 hours post induction of DOMS using pressure algometer device. They were given 2 sessions of LASER therapy at 24 hours and 48 hours and were assessed again post treatment.
Results
Results: Significant improvement was seen for pain pressure threshold (p<0.001) post 48 hours for the participants.
Conclusions
Conclusion: LASER therapy is effective in reducing pain and improving pain pressure threshold in individuals with delayed onset muscle soreness (DOMS) in biceps brachii muscle.
