Study summary

A randomized controlled study with six months follow-up will be conducted to investigate the effects of sagittal head posture correction on 3D spinal posture parameters, back and leg pain, disability, and S1 nerve root function in patients with chronic discogenic lumbosacral radiculopathy . Participants will include 80 patients between 40 and 55 years experiencing chronic discogenic lumbosacral radiculopathy with a definite hypolordotic cervical spine and forward head posture and will be randomly assigned a comparative treatment control group and a study group. Both groups will receive TENS therapy and hot packs, additionally, the study group will receive the Denneroll cervical traction orthotic.

Read the detailed description

Despite the fact that there is some evidence of a link between low back pain and head posture , there is limited experimental data to support a cause-and-effect relationship and interventional outcomes. Accordingly, a prospective, randomized, controlled study will be conducted at a research laboratory of our university to investigate if cervical curve restoration and forward head posture correction will have short and long term effects on three dimensional spinal posture parameters as well as lumbar radiculopathy management outcomes such as symptoms, disability, and neurophysiological findings .In this study we will use an orthotic cervical traction termed the Denneroll to help restore normal sagittal spinal configuration based on principles of 3-point bending traction methods. Interventions will be applied at a frequency of 3 times per week for 10 weeks and groups will be followed for an additional 6-months.

Study arms

  • Experimental
    Deneroll cervical extension traction

    The study group will receive 3-point bending cervical extension traction following the protocol of Deed Harrison . The duration of each session will start at approximately three minutes and increased one minute per session until reaching the goal of 20 minutes per session

    Other: Deneroll cervical extension traction · Other: Traditional treatment

  • Active comparator
    Traditional treatment

    The participants will receive hot packs (15 minutes) and TENS therapy to control pain and eliminate the causal role of muscle spasms and/or tightness in changing the posture parameters.

    Other: Traditional treatment

Interventions

  • OtherDeneroll cervical extension traction

    Participants will lie flat on their back on the ground with their legs extended and arms by their sides. The denneroll will placed on the ground and positioned in the posterior aspect of the neck depending on the area to be addressed . The apex of the Denneroll orthotic will be placed in one of three regions based on lateral cervical radiographic displacements: 1. In the upper cervical region (C2-C4) region. 2. The apex of the Denneroll orthotic is placed in the mid-cervical region (C4-C6) region. 3. The apex of the Denneroll orthotic is placed in the upper thoracic lower-cervical region (C6-T1) region.

  • OtherTraditional treatment

    The participants will receive hot packs (15 minutes) and TENS therapy .During TENS application. Patients will be asked to adopt a prone position. The TENS therapy will be delivered at the lumbosacral region for 20 min. The frequency will set to 80 Hz and pulse width to 50 µs due to its analgesic effect . These conventional treatments will be repeated three times per week over the course of 10 weeks for 30 total sessions

What researchers measure

Primary outcomes

  1. The Change in cervical absolute rotatory angle

    Cervical absolute rotatory angle is formed by two lines intersecting from the posterior body margins of C2-C7 and forward head distance

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

  2. The Change in anterior head translation

    anterior head translation is measured as the horizontal displacement of the posterior superior body corner of C2 vertebra relative to a vertical line extending superiorly from the posterior inferior body corner of C7..

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

Secondary outcomes

  1. The change in 3D spinal posture parameters

    Rasterstereography sagittal plane parameters (lumbar angles, thoracic angles, and trunk inclination), the frontal plane parameters (trunk imbalance and lateral deviation) and the transversal plane parameters (vertebral surface rotation and pelvis torsion) will be selected to cover the posture profile in three planes

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

  2. The change in pain intensity

    Measurement of pain will be performed by using a visual analogue scale (VAS). The subjects will be asked about the perception of pain using a 10-cm line with 0 (no pain) on one end and 10 (worst pain) on the other. subjects will be asked to place a mark along the line to denote their level of pain

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

  3. The change in disability level

    Disability will be measured using the Oswestry Disability Index. The total score is transferred onto a scale ranging from 0 to 100, where 0 indicates no disability and 100 indicates worst possible disability

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

  4. The change in peak to peak amplitude of H reflex

    The H-reflex (or Hoffmann's reflex) is a reaction of muscles after electrical stimulation of sensory fibers (Ia afferents stemming from muscle spindles) in their innervating nerves

    Time frame: will be measured at three intervals :pretreatment, 10 weeks post treatment, and at six months of follow-up

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2011 to primary completion in May 2012, 12 months.

Of 180 non-industry interventional studies with no phase under Intervertebral Disc Displacement, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 27. This study's 12 months is close to that.

Counting every sponsor, half of 196 studies reached it within 12 months; a quarter within 6 and three quarters within 30.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 23, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
