Lateral Neck Flexor Endurance and Hyperlaxity

The lateral neck flexor endurance test has been proposed to assess for unilateral muscular deficits. It is not known if individuals with hyperlaxity have different muscular endurance than individuals without hyperlaxity.

About this study

Thirty individuals with systemic hyperlaxity as determined with the Beighton scale will be assessed for lateral neck flexor endurance and compared to age and gender matched controls. Basic demographic information will be collected, and all individuals will report Neck Disability Index (NDI) and Numeric Pain Rating Scales (NPRS) for their neck, as well duration of any neck pain. All participants will then undergo testing of lateral neck flexor muscle endurance, repeated twice on each side. Average hold times will be compared for individuals with hyperlaxity (5 or greater on Beighton scale) and the healthy age and gender matched controls. Analysis will also include covariates of NDI scores, pain scores, and chronicity of symptoms.

Inclusion criteria

systemic hyperlaxity of 5 or greater on Beighton Index, healthy age/gender matched controls

Exclusion criteria

  • neck pain that spreads into the arms;
  • whiplash injury within the last 6 weeks;
  • diagnosed neuropathy or other nervous system disorders;
  • a history of spinal surgery in their neck;

lateral neck flexor endurance test

Other

Individuals will maintain the head in a neutral position off the ground in sidelying for as long as possible.

Primary outcomes

  1. lateral neck flexor endurance

    Time frame: single testing session at enrollment

    maximum hold time

Secondary outcomes

  1. Beighton Hyperlaxity Scale

    Time frame: at enrollment

    Assessment of systemic hyperlaxity, 0-9 points, higher indicates greater hyperlaxity

  2. Neck Disability Index

    Time frame: at enrollment

    Questionnaire assessing impact of neck symptoms on function, 0-100 points, higher score indicates greater disability

  3. Numeric pain rating scale

    Time frame: at enrollment

    assessment of neck pain, 0-10 with higher indicating greater levels of pain
