Dynamic Cervical Orthosis (DCO)

The DCO is the most advanced system available for the treatment of head drop. This truly dynamic device is the only system available that supports a neutral, midline position, while still allowing normal movement. Through the use of the dynamic resistance bands, the DCO offers a resistance to movement helping to facilitate strengthening of the musculature of the neck, while assisting with re-centering in midline.

Uses of DCO

  • To stabilize the head for the patient population that either congenitally, pathologically or traumatically loses the ability to stabilize the head.
  • This device is primarily designed for patients with a lack of voluntary control of the head and neck, often secondary to Cerebral Palsy, Multiple Sclerosis, Spinal Muscular Atrophy and severe Hypotonia.
  • These patients are not able to consistently control the position of their heads and have a difficult time functioning normally. As a result, this device will help to better position their heads to engage the world around them and improve their function and independence.
  • To stabilize the head and neck in a neutral midline position, facilitating improved breathing, swallowing and speech patterns, as well as the ability to engage the environment.
  • To offer graded resistance to movement, creating an overall strengthening of the muscles used to control the head and neck.

DCO Characteristics

The Strapping System

  • Shoulder Straps: Via a chest strap and figure “8”, the device provide to the patient a shoulder straps that prevents from shoulder enrollment.
  • Chest Strap: Provides an attachment point for a circumferential chest strap, which anchors the DC

The Dynamic Cervical Orthosis

  • The specific durometer of the elastic bands is determined as part of the fitting and treatment of the user.
  • Stabilizes the head in neutral position
  • Movement against resistance, allowing for strengthening of the neck muscles

For a Better Head Control

  • The upright is easily contoured to match the user’s natural spinal curvature and head shape.
  • The occipital support is also lined with a soft foam interface
  • The user wears a strap around the head at about the glabella level
  • When the user dons the device, the straps are connected around the chest and around the shoulders. The head strap is donned and snugged in place
  • Head band is connected to the occipital support via elastic bands
  • These elastic bands help to stabilize the head in neutral position.
  • Movement of the head is then against resistance, allowing for strengthening of the musculature of the neck, resulting in improved head control


  • Poor Head Control
  • Neck Weakness
  • Head Drop (Ptosis)
  • Parkinson’s Disease
  • Multiple Sclerosis
  • Myopathy
  • Amyotrophic Lateral Sclerosis
  • Poor Head Control Due to
  • Hypotonic Cerebral Palsy


  • Rigidity of the Neck Musculature
  • Fusion of the Cervical Vertebrae
  • Fixed Neck Position

In Comparison with Other Orthosis

  • The other existing orthosis are considered as head support with both anterior and posterior supports.
  • They show no similarity to the function of the DCO They mainly immobilize the head in a static position (lacking functionality) such as Sternal, Occipital, Mandibular Immobilizer (SOMI), or a 4 points cervical orthosis.
  • DCO system allows to correct the head position in a dynamic way. This will allow the patient to be able to move his head in all directions (functional).
  • DCO system will provide a “Rappel System” bringing the head to a the initial corrected position after each movement.
  • DCO system provides a graded elastic assisting aid to the patient. This aid could even be modified according to the patient improvement
