fulfilment of the Inclusion and Exclusion criteria. 30
employees were selected randomly and equally divided into 2
groups- Control group and Experimental group.
Control group continued with their usual activities without the
therapeutic exercise program and experimental group
underwent therapeutic exercise program for neck and
shoulder pain. The treatment duration was 30 minutes thrice
in a week.
On statistical analysis of Numeric Pain rating scale scores, the
mean pre-treatment pain score of control and experimental
group was 6.33 and 5.93 and mean post treatment pain scores
of control and experimental group was 4.27 and 6.33
respectively. This result shows that there is an increase of -0.4
units of pain in control group and a decrease of 2.06 units of
pain in experimental group; which indicates that there is a
considerable decrease in pain in experimental group.
Bruno et al., (2008) found that maintaining static posture for a
prolonged time as seen in occupational setting compresses the
veins and capillaries inside muscles thereby causing micro-
lesions from the absence of oxygenation and nutrition.
Handloom workers needs static working postures for
prolonged durations which leads to compression of veins and
capillaries, which in turn leads to decreased oxygen supply to
the muscle and decreased waste removal, this causes muscle
imbalance, fatigue, discomfort and pain as a result of
disruption of tissues. Stretching lengthens the muscles which
are shortened, deprived of oxygen, makes the muscle pliable,
increases oxygen supply, remove waste products thus
decreasing pain.
On statistical analysis, the mean pre-treatment SPADI scores
of control and experimental group were 48.57 and 39.84and
mean post treatment SPADI score of control and experimental
group was49.03 and 50.39 respectively. Since there is a
significant difference existing between the pre-test and post-
test SPADI scores among individuals in the experimental
group.
From the statistical analysis we understood that experimental
group who were undergone stretching and strengthening have
more effects than that of persons who didn’t undergone
therapeutic exercise
The mechanism for which can be similar to the one explained
by Magnusson et al., 1996. In their study they found that
stretching reduces pain and following that there is consequent
improvement in function by elongation of the muscle tendon
unit, reduction in peak force, decrease in rate of force
production and tensile stress on the muscle tendon unit, and
alteration of the visco- elastic property of the muscle-tendon
unit, thus resulting in less tight tissue.
On the basis of the finding is can be assumed that the
Handloom workers must be engaging in regular and
systematic exercise routines such that they can prevent the ill
effects of prolonged static posture which is an integral part of
their profession.
Conclusion
Statistically it is observed that, the stretching and
strengthening exercise leads to a significant improvement in
strength and decrease neck and shoulder pain of the subjects
under study. Based on the performed study, it can be
concluded that stretching and strengthening exercise therapy
can be performed as a daily routine to improve strength and to
decrease pain on neck and shoulder.
