Objective: 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 (n = 48) received ultrasound and infrared radiation, whereas the exercise group (n = 48) 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 P = 0.000, 0.01, 0.000, 0.001 respectively and at follow-up for all previous variables (P = 0.000).
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.
