AbstractObjective: To investigate the effect of forward head posture correction on pain and nerve root function
in cases of cervical spondylotic radiculopathy.
Design: A randomized controlled study with six months follow-up.
Setting: University research laboratory.
Subjects: Ninety-six patients with unilateral lower cervical spondylotic radiculopathy (C5–C6 and C6–
C7) and craniovertebral angle measured less than or equal to 50 were randomly assigned to an exercise
or a control group.
Interventions: The control group (n¼48) received ultrasound and infrared radiation, whereas the
exercise group (n¼48) received a posture corrective exercise programme in addition to ultrasound
and infrared radiation.
Main outcome measures: The peak-to-peak amplitude of dermatomal somatosensory evoked potentials,
craniovertebral angle, visual analogue scale were measured for all patients at three intervals
(before treatment, after 10 weeks of treatment, and at follow-up of six months).
Results: There was a significant difference between groups adjusted to baseline value of outcome at
10 weeks post-treatment for craniovertebral angle, pain, C6 and C7 peak-to-peak amplitude of dermatomal
somatosensory evoked potentials P¼0.000, 0.01, 0.000, 0.001 respectively and at follow-up for all
previous variables (P¼0.000).
Conclusion: Forward head posture correction using a posture corrective exercise programme in
addition to ultrasound and infrared radiation decreased pain and craniovertebral angle and increased
the peak-to-peak amplitude of dermatomal somatosensory evoked potentials for C6 and C7 in cases of
lower cervical spondylotic radiculopathy.
