Improvement In Neck Curve and Posture Using the Denneroll Improves Long Standing Dizziness, Neck Pain, and Disability in Cervico-Genic Dizziness Sufferers.

Dizziness
Cervicogenic dizziness is a frequent disorder that is strongly associated with delayed recovery, persistent disability, psychologic distress and increased health care utilization and costs.1, 2 Despite the relatively high prevalence of this condition, its management has long been a challenge for both clinicians and patients.3-5 In general there is mild-moderate (30-50% improvement in the condition) short term treatment outcomes immediately after intervention and 3- month follow up, however, there is no strong evidence for the effectiveness of most treatments at long-term management follow-ups of 1 year or longer.

Causes of Cervico-Genic Dizziness

There is evidence that cervicogenic dizziness is a result of perturbation in the information from sensory afferents in the cervical spine.6 Abnormal alignment of the cervical lordotic curve from the side view (straightening and kyphosis) has been found to result in degenerative changes in the muscles, ligaments, intervertebral discs and bony structures of the cervical spine.7,8 This altered alignment and degenerative cascade could potentially lead to mechanoreceptive dysafferentation (abnormal and altered barrage of afferent neurological input). A correction of altered cervical spine alignment therefore, might be required to achieve optimal information from sensory afferents in the cervical spine, where the signs and symptoms of patients with cervicogenic dizziness can be decreased. The development of effective intervention strategies and trials testing this concept in Dizziness patients is thus sorely needed.

New Breakthrough Randomized Trial9

Recently a breakthrough randomized trial was conducted at Cairo University in Egypt and co-authored by CBP NonProfit President Dr. Deed Harrison, DC. The Cairo University team was led by Professor Ibrahim Moustafa, PT, PhD and included collaborating author Professor Aliaa Diab PT, PhD.9

Clinical features: The study investigated 72 patients (47 males) aged 40-55 years with chronic pain and disability with a primary complaint and diagnosis of cervico-genic dizziness. The short (10-weeks) and long term (1-year) outcomes of neck pain, dizziness severity and frequency, and cervical positioning sense were assessed in the project.

Interventions: The investigation used a standard intervention frequency and duration of 3x per week for 10 weeks or 30 total treatment sessions. Patient participants were assigned equally to one of two groups: Denneroll group and Non-Denneroll Group. Of interest both groups received a standardized multiple treatment procedure protocol including:

  • Cervical Spinal joint mobilization therapy for the cervical spine,
  • Myofascial stretching and release techniques to the sub-occipital spine,
  • Tens and hot packs to the cervical region,
  • Functional and strengthening exercise protocol designed to improve strength, flexibility, posture, and reduce pain,
  • A series of home care instructions.

Only the Denneroll group received the cervical denneroll in addition to the standardized multiple treatment techniques. Figure 1. shows the Cervical Denneroll device.

All treatments were applied 3x per week for 10 weeks. At the end of the 30 treatments, following a minimum of 1-day with no treatment, all subjects were re-evaluated. Lastly, treatment was then stopped and all subjects were followed for an additional 1-year to see if the 10-week outcomes were maintained at this long term follow up.

Important Findings and Conclusion: The addition of the cervical denneroll orthotic device to a multi-modal physical therapy intervention program was found to improve the cervical lordotic curvature by an average of 14° and improve anterior head translation by 2.4cm. This improvement in cervical curvature and posture in the Denneroll group was found to be associated with improvement in dizziness disability and severity and frequency, chronic neck pain, and head repositioning accuracy. In the group receiving the denneroll and consequent curve correction, their results were maintained at 1-year follow up whereas the control subjects regressed back to baseline values for all clinically relevant measures.16
