Abstract

Background: Den􀆟 st sits in a chair and leans forward towards
the pa􀆟 ent, lumbar curve fl a􀆩 ens and the bony infrastructure
provides very li􀆩 le support to the spine. Si􀆫 ng in chair forces
the hamstrings to become inac􀆟 ve and places them in a
shortened posi􀆟 on. Repe􀆟 􀆟 ve, prolonged si􀆫 ng eventually
leads to hamstring muscles that adapt to a new shortened
length, and the result is Hamstring 􀆟 ghtness which induces
posterior pelvic 􀆟 lt and decreased lumbar lordosis, which can
result in low back pain
Objec􀆟 ve: We inves􀆟 gated eff ects of hamstring stretch with
pelvic control on pain, disability and work ability in Den􀆟 st
with mechanical low back pain.
Methods: Thirty Den􀆟 st from Dental professional were
randomly assigned to pelvic control hamstring stretching
(Group A) (n = 15) and Supine hamstring stretching (Group
B) (n = 15). All interven􀆟 ons were conducted 3 days per week
for 6 weeks, and included in the hamstring stretching and
lumbopelvic muscle strengthening.
Outcomes: Outcomes were evaluated through Numeric pain
ra􀆟 ng scale (NPRS) for Pain, Oswestry disability index (ODI) for
Disability, and Work ability index (WAI) for Work ability.
Results: The paired t-test was used to compare within group
diff erences and unpaired t-test was used to compare the
between group diff erences. All sta􀆟 s􀆟 cal analyses were
performed using SPSS sta􀆟 s􀆟 cal so􀅌 ware version 21.Signifi cant
diff erences found between Group A and group B in all three
variables.(p<0.05).between pre and pos􀆩 est of subjects.
According to the results of the present research, it could be
concluded that for reducing pain, disability and work ability
in den􀆟 sts pelvic control hamstring stretch and lumbopelvic
strengthening exercises are recommended.
Conclusions: The pelvic control hamstring stretch exercise
would be more helpful in back pain reduc􀆟 on and improvement
of work ability in Den􀆟 st with mechanical low back pain.
