Spinal
stenosis.

At a glance

Spinal stenosis is narrowing around spinal nerves or the spinal cord that can affect walking tolerance, sensation, strength or coordination. 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.

Spinal stenosis describes narrowing of the spaces within the spine, which can reduce room around the spinal cord or nerves. In the lower back it often causes leg pain, heaviness or numbness with walking that eases with sitting or leaning forward; in the neck it may affect balance, coordination or hand function. Distinguishing stenosis from vascular or hip causes of leg symptoms is the first step toward a plan that preserves walking tolerance and independence.

Common causes

  • Age-related thickening of ligaments and enlargement of facet joints.
  • Disc bulging or herniation narrowing the spinal canal or nerve openings.
  • Bone spurs associated with spinal arthritis.
  • A vertebra that has shifted forward relative to its neighbor.
  • Less commonly, congenital narrowing of the spinal canal.

How we evaluate

History focuses on the relationship between symptoms and walking, standing and sitting, plus any changes in balance, hand dexterity or bladder function. A hands-on osteopathic and physiatric examination assesses strength, sensation, reflexes, gait and provocative positions. Prior MRI or CT is reviewed in the context of the examination, since narrowing on imaging does not always explain symptoms, and EMG/NCS may help separate stenosis from peripheral nerve problems. Examination findings determine whether a rehabilitation plan, a procedure or a surgical opinion fits best.

Treatment options
we may discuss.

  • Performance Health / rehabilitation

    Rehabilitation may address flexion-tolerant movement strategies, hip and trunk strength, balance and graded walking programs to extend comfortable activity. Pacing and bicycle-based exercise often suit people whose symptoms limit walking. Many people with spinal stenosis can be managed without surgery; a surgical opinion is sought only when function is declining, neurological findings are progressing or conservative care has been given a fair trial.

  • Regenerative & Cell-Based Medicine

    Regenerative care may be discussed for a separate, clearly identified joint or tendon contributor to spine-region pain. PRP, prolotherapy and cell-based or biologic therapies are not established treatments for narrowing around the spinal cord or nerves. Any separate tissue indication requires its own review of evidence, risks and applicable law, with rehabilitation remaining central.

  • Targeted Pain Management

    Medication review and precise, image-guided, nerve-targeted procedures may be discussed for an identified pain source. When it's needed, an image-guided epidural steroid injection can calm an inflamed nerve root and support participation in rehabilitation. Benefits, limitations and risks are weighed alongside the overall plan. Procedures are image-guided, using ultrasound or X-ray guidance depending on the target.

Common
questions.

When to seek
care urgently.

Seek emergency care for new bladder or bowel dysfunction, numbness around the groin, rapidly worsening leg weakness, or new difficulty walking with hand clumsiness.
