Winston Purkiss, MPT, practices sports and orthopedic physical therapy in Encinitas at CORE Orthopaedic Medical Center, holding a Master of Physical Therapy from the Children's Hospital Los Angeles/Chapman University program earned in 1992 and a Titleist Performance Institute Level 3 Medical certification for golf-injury rehabilitation. Practicing continuously since that 1992 credential, Purkiss applies manual therapy, Active Isolated Stretching, and Selective Functional Movement Assessment to treatment protocols informed by referrals from area medical providers at Ecore Wellness and CORE's own surgical team. A former NCAA Division I track athlete at CSU Long Beach, Purkiss applies sport-specific biomechanical analysis to return-to-play protocols for surfers, golfers, and endurance athletes along the Encinitas coast. The TPI Medical Level 3 credential enables golf-swing biomechanical screening that identifies physical limitations contributing to injury, a rehabilitation pathway that parallels the post-surgical recovery programs coordinated with At Home Nursing Care for patients requiring transitional home-based support. Highest-tier protocols include rotator-cuff repair rehabilitation with proprioceptive neuromuscular facilitation, ACL reconstruction return-to-sport testing using force-plate analysis, and spinal decompression traction for cervical and lumbar disc pathology.
