Physical Therapy
Our physical therapy services focus on personalized, one-on-one treatment plans for orthopedic injuries, post-operative recovery, and chronic pain management. Using evidence-based techniques like manual therapy and dry needling, we help patients regain mobility and strength. Our Omaha clinic emphasizes injury prevention and functional restoration, ensuring each patient achieves their unique health goals through tailored interventions.
Sports Performance Training
Designed for athletes of all levels, our sports performance training integrates strength conditioning, agility drills, and biomechanical analysis to enhance athletic capabilities. We utilize cutting-edge equipment and sports-specific programming to improve power, speed, and endurance while minimizing injury risks. Our team of certified strength coaches and physical therapists ensures safe, effective training tailored to individual sport demands.
Dry Needling
Dry needling at C.O.R.E. targets muscle tension and trigger points to alleviate pain and improve mobility. This advanced technique, performed by certified therapists, accelerates recovery by releasing tight muscle bands and promoting healing. Combined with manual therapy and corrective exercises, it offers a comprehensive approach to resolving musculoskeletal issues and restoring optimal function.
Manual Therapy
Our manual therapy techniques include joint mobilizations, soft tissue work, and muscle energy techniques to address musculoskeletal dysfunction. These hands-on interventions improve range of motion, reduce pain, and correct postural imbalances. Delivered by licensed physical therapists, this service is integrated with exercise prescription to ensure long-term recovery and functional improvement for patients.
Gait Analysis
Gait analysis at C.O.R.E. uses slow-motion video and laser feedback to evaluate walking and running mechanics. This detailed assessment identifies inefficiencies and asymmetries contributing to pain or injury. Customized corrective strategies, including exercise and taping, are then implemented to enhance movement patterns, performance, and injury prevention for active individuals and athletes.
