Abstract :
Background and Objective - Shoulder
Impingement Syndrome (SIS) is a common cause of
shoulder pain in adults. People with this condition
experience pain related to the shoulder's tendons and soft
tissues when lifting the arm overhead. The Pectoralis
Minor muscle was found to be significantly more active
during elevation in subjects with SIS. Increased activity is
indicative of a shortened muscle. When this muscle is in a
shortened position however, it can limit scapular upward
rotation, which is necessary for shoulder elevation, while
causing excessive anterior tilting and internal rotation of
the scapula. The increased anterior tilt and internal
rotation caused by Pectoralis Minor tightness
mechanically reduce the Subacromial space, and has been
associated with symptoms commonly seen with SIS.
Physiotherapy techniques like Myofascial Release (MFR)
and Muscle Energy Technique (MET) have been
proposed as an adjunct to Conventional therapy to treat
Shoulder Impingement Syndrome. Both the techniques
have been proven to be effective on increasing Pectoralis
Minor length, reducing Pain, improving Function in
Subjects with Shoulder Impingement Syndrome and
studies are limited on their Comparison. Hence need of
the Study arise.
Methods - Prospective study design. 64 subjects with age
groups between 18 and 35 years having a Clinical
Diagnosis of Shoulder Impingement Syndrome were
randomly allocated in to two groups. In Group A (n=32)
subjects were treated with Myofascial Release (MFR)
whereas in Group B (n=32) subjects received Muscle
Energy Technique, Participants were given intervention
thrice a week for 6 weeks. The outcome measures of this
intervention were measured in term of VAS for Pain,
SPADI for Function and PMI for Pectoralis Minor
Length.
Result - Independent‘t’test was used to compare the mean
significance difference between continuous variables.
Paired‘t’test was used to assess the Statistical significance
difference between Pre and Post test scores. Statistical
analysis of the data revealed that within the group
comparison, both groups showed significant
improvement in all parameters. Whereas in between the
group’s comparison Muscle Energy Technique showed
better improvement when compared to Myofascial
Release.
Conclusion - After 6 weeks of intervention, Both
Myofascial Release and Muscle energy technique
intervention showed significant improvement on
Pectoralis minor length, Pain and function. However,
Muscle Energy Technique group is found to be more
effective when compared to Myofascial Release group.
From the findings of the current study, it is recommended
that Muscle energy technique protocol may be
incorporated in the management of Shoulder
Impingement Syndrome
