Sports &
overuse injuries.

At a glance

Sports and overuse injuries affect muscles, tendons, joints or bones after a single event or repeated loading beyond their current tolerance. 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.

Sports and overuse injuries can follow a single event or develop when repeated demand exceeds the current tolerance of a tendon, muscle, bone or joint. Pain during training is not always a sign of the same tissue problem, and pushing through it can obscure an injury that needs a different approach. An accurate diagnosis helps distinguish a manageable loading issue from a structural injury and gives rehabilitation a clear clinical starting point.

Common causes

  • Tendon overload after changes in training volume, intensity or recovery.
  • Muscle strain during acceleration, lifting or unfamiliar physical activity.
  • Ligament sprain or joint injury following a twist or impact.
  • Bone stress injury associated with repetitive loading and limited recovery.
  • Recurring pain related to movement control or incomplete prior rehabilitation.

How we evaluate

History considers the injury mechanism, training changes, previous injuries and the demands of the person's sport or daily activity. A hands-on osteopathic and physiatric examination assesses the involved tissues, strength, joint stability and movement patterns, including nearby regions that may influence loading. Prior imaging is reviewed, and diagnostic ultrasound may help clarify selected tendon or soft-tissue findings, while EMG/NCS is reserved for an appropriate suspected nerve problem. A possible fracture, major tendon rupture or unstable joint may need additional imaging or specialist referral before planning a return to exercise or considering a procedure.

Treatment options
we may discuss.

  • Performance Health / rehabilitation

    An individualized plan may address load adjustment, progressive strengthening, movement technique and staged return to sport. Recovery planning reflects training demands rather than a fixed timetable, with therapist coordination and progression guided by symptoms and examination. Most sports and overuse injuries can be managed without surgery; a surgical opinion is sought only when a major rupture, unstable injury or other structural finding truly requires it.

  • Regenerative & Cell-Based Medicine

    When appropriate, PRP may be discussed for selected tendon or joint injuries, and prolotherapy for selected ligament-related problems, according to the evidence for the diagnosis. Cell-based and biologic options require separate review of evidence, risks and applicable law and are not interchangeable with PRP. Regenerative care complements graded rehabilitation, not necessary structural assessment or treatment of a bone stress injury.

  • Targeted Pain Management

    Medication review and precise, image-guided care may be considered for a clearly identified pain source, with nerve-targeted procedures such as nerve blocks reserved for a relevant focal indication. An injection is not automatically appropriate for a fresh tendon injury or suspected bone stress injury. Tissue, timing, alternatives and rehabilitation guide decisions. Procedures are image-guided, using ultrasound or X-ray guidance depending on the target.

Common
questions.

When to seek
care urgently.

Seek urgent care for deformity, inability to bear weight after injury, sudden loss of limb function, or severe swelling with numbness or a cold limb.
