Effectivenessof Isometric And Stretching Exercises with and Without Ergonomics in Mechanical Neck Pain among Dental Students
Keywords:Mechanical Neck Pain, Standardised Nordic Questionnaire, Neck Disability Index, Numeric Pain Rating Scale, Dental Students
Background & Purpose: In the practice of dentistry, stress, tension and postural practices can contribute
to neck and lower backache problems. This is due to the limited work area with a limited scope of
movement and narrow visual field associated with the oral cavity. The prevalence and severity of various
musculoskeletal disorders decreased by performing regular specific exercises among large group of the
dentists. The ergonomic hazards, caused by strained posture and prolonged repetitive movements, can
induce musculoskeletal disorders. The symptoms begin to appear early in their dental carrier. Objectives:
This study is to compare the effectiveness of isometric and stretching exercises with and without ergonomic
advice in mechanical neck pain among dental students.
Methods: The investigator personally visited two different dental colleges in Bengaluru, obtained permission
from the concerned authorities and screened final year students and interns using standardized Nordic
Questionnaire forms. Students with mechanical neck pain were then selected according to the inclusion and
exclusion criteria. The selected students from two dental colleges were grouped as Group A and Group B.
The students were asked to fill NDI and NPRS forms prior the intervention. Group A were given isometric
and stretching exercise along with ergonomic advice, whereas group B were given isometric and stretching
exercises only. The students were asked to follow the protocol for 4 weeks. NDI and NPRS were the outcome
Result: The incidence of mechanical neck pain among 152 dental students screened was 52.63%. 14 out
of 60 students who participated in the study were male. Paired t-test and unpaired t test were used for
statistical analysis within the group and between the group respectively. Both the groups improved in pain
and disability associated with mechanical neck pain. But improvement in neck related complications in
group A was more significant than group B in this study. The difference in P value for both NDI and NPRS
between both the groups was highly significant.
Conclusion: Isometric and stretching exercises with ergonomic advice were more effectiveness than
isometric and stretching exercise without ergonomic advice in mechanical neck pain among dental students.
