Ehlers-Danlos &
hypermobility.

At a glance

Hypermobility means joints move beyond their usual range, while Ehlers-Danlos syndromes are distinct connective-tissue disorders that can involve instability and pain. 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.

Hypermobility describes joints that move beyond the usual range; it does not by itself establish an Ehlers-Danlos syndrome diagnosis. Some people experience recurrent instability, muscle overload or persistent pain, while others have flexibility without symptoms, and Ehlers-Danlos syndromes include distinct conditions with different implications. Identifying the functional problem and reviewing an established diagnosis helps shape a joint-protective plan without assuming that every symptom has the same cause.

Common causes

  • Joint laxity contributing to recurrent sprains or episodes of instability.
  • Muscle overload while trying to stabilize joints during everyday activities.
  • Tendon irritation related to repeated loading or poorly tolerated movement.
  • Changes in movement control and awareness of joint position.
  • Nerve irritation or other coexisting conditions that need separate evaluation.

How we evaluate

History includes recurrent injuries, dislocations, established diagnoses, previous therapy and the activities that are difficult to tolerate. A hands-on osteopathic and physiatric examination considers joint motion, stability, strength and movement control, avoiding the assumption that greater flexibility should be pursued. Existing imaging and specialist records are reviewed, with diagnostic ultrasound or EMG/NCS considered when a focused tendon or nerve question warrants it rather than as routine hypermobility screening. Suspected syndromic features or symptoms outside musculoskeletal care may call for coordination with appropriate specialists, and a pain evaluation does not substitute for a formal Ehlers-Danlos subtype assessment.

Treatment options
we may discuss.

  • Performance Health / rehabilitation

    Joint-protective strengthening, gradual loading and movement-control work may be coordinated with a therapist familiar with hypermobility. Pacing and selective supports favor control within a useful range rather than aggressive stretching. Many people with hypermobility-related pain can be supported without surgery; a surgical opinion is sought only for a clearly defined problem that truly needs it, with particular attention to tissue fragility.

  • Regenerative & Cell-Based Medicine

    When appropriate, PRP or prolotherapy may be discussed cautiously for a separate tendon, joint or ligament indication, recognizing limited evidence in hypermobility and individual tissue risks. Cell-based and biologic options require careful evidence and regulatory review. These approaches are not established treatments for the underlying connective-tissue disorder and are not proposed to reverse Ehlers-Danlos syndrome; rehabilitation remains the foundation.

  • Targeted Pain Management

    Careful medication review and conservative, precise, image-guided, nerve-targeted care may be considered for a clearly identified pain source. Selected nerve blocks require attention to subtype, tissue characteristics, prior responses and procedural risks. Procedures are not assumed to correct generalized laxity or replace sustainable rehabilitation. 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 sudden severe chest, abdominal or head pain, new neurological symptoms, or an injured joint with loss of sensation or circulation.
