Whiplash &
car accident injuries.

At a glance

Whiplash is a neck injury from rapid back-and-forth movement that can affect muscles, ligaments, joints, discs or nerves after a collision. Institute of Function starts with diagnosis and rehabilitation, considering the least invasive effective option and procedures only when examination supports them. Dr. Benjamin (Ben) Klyachman, D.O., board-certified in pain medicine and physical medicine and rehabilitation, leads care at Institute of Function in Nassau County, NY, which welcomes patients from across Long Island, New York City and beyond.

Whiplash describes a neck injury caused by a rapid back-and-forth movement, most often in a motor vehicle accident, and it can involve muscles, joints, discs and nerves. Symptoms may include neck pain, headache, shoulder discomfort or arm symptoms, and they sometimes appear days after the collision. Early evaluation documents the injuries, rules out serious problems and establishes a plan, with careful documentation of the injuries from the first visit.

Common causes

  • Rear-end or side-impact collisions producing rapid neck acceleration.
  • Muscle and ligament strain from the sudden movement.
  • Facet joint or disc injury identified on examination or imaging.
  • Nerve irritation causing arm pain, numbness or tingling.
  • Headache related to neck structures or, less often, concussion requiring separate assessment.

How we evaluate

History covers the collision mechanics, the timing of symptoms, prior injuries and any imaging performed after the accident. A hands-on osteopathic and physiatric examination assesses neck motion, strength, sensation, reflexes and signs that the spine, nerves or brain may need further evaluation. Prior imaging is reviewed, diagnostic ultrasound may assess selected soft-tissue questions, and EMG/NCS may be considered for persistent arm symptoms. Documentation is maintained carefully to support care coordination, and findings that suggest fracture, instability or concussion direct prompt referral.

Treatment options
we may discuss.

  • Performance Health / rehabilitation

    Early, graded movement and a progressive rehabilitation plan are generally favored over prolonged rest or immobilization. Care may address neck and shoulder strength, comfortable mobility and a staged return to work and driving. Most whiplash injuries can be managed without surgery; a surgical opinion is sought only when evaluation identifies a structural problem that truly requires it.

  • Regenerative & Cell-Based Medicine

    When appropriate, PRP or prolotherapy may be discussed for selected ligament or joint injuries once the acute phase has passed, with evidence that varies by structure. Cell-based and biologic options require a separate review of evidence, risks and applicable law. These are not treatments for concussion or nerve injury, and rehabilitation remains the foundation.

  • Targeted Pain Management

    Medication review and precise, image-guided, nerve-targeted procedures may be discussed for an identified pain source, such as facet joint pain confirmed by diagnostic blocks, with radiofrequency ablation considered after appropriate assessment. When it's needed, an image-guided injection can also calm an inflamed joint or nerve. Procedures are image-guided, using ultrasound or X-ray guidance depending on the target.

Common
questions.

When to seek
care urgently.

Seek emergency care after an accident for severe neck pain with deformity, new weakness or numbness, difficulty walking, loss of bladder control, or worsening headache, confusion or vomiting.
