A Study on Effect of Phonophoresis on the Management of Delayed Onset Muscle Sorenessin Healthy F’emale Adults

Abstract

Background: Delayed-onset muscle soreness (D OMS) is described as a sensation of pain and stiffness
in skeletal muscle following a session of rigorous or unaccustomed exercise. Many interventions have
been used in an attempt to prevent delayed onset muscle Soreness. This include stretching, massage,
cryotherapy, electrical stimulation, ultrasound, pharmacological agents, and warm up and cool-down.
Warm up (Gentle exercise preceding vigorous physical activity) is said to reduce muscle strain injuries
by increasing muscle temperatures and hence muscle compliance. The effectiveness of ultrasound on
DOMS shows that ultrasound enhanced the development of DOMS but that this enhancement was
offset by the anti-inflammatory analgesic action of salicylate phonophoresis. Study aimed to compare
the effectiveness of warm up and phonophoresis on the management of DOMS in healthy female adults.
Material & Method: This comparative study was conducted among the 40 subjects of age group
ranging frorn 18 to 25 years recruited from Yenepoya University. Prior to participation, the subjects
were explained about the study and obtained an informed consent from all the participants. Tenderness
was measured in 10 minutes 24and 48 hours after exercise by applying a pressure algometer and
recorded the measurement
Result: Total of 40 female who consented to be part of study were included and grouped as Group A
(Warm-up) and Group B (Phonophoresis). The results of this study showed effect of phonophoresis on
DOMS is more than warm up. There was a statistically significant difference in the mean between the
two groups (p<0.001), warm up and phonophoresis group
Conclusion: The study showed that phonophoresis is more effective in alleviating DOMS than warm
up.
