Services
Physical Therapy
Our physical therapy services focus on restoring mobility, reducing pain, and improving overall function through personalized treatment plans. We address post-injury recovery, post-surgical rehabilitation, and chronic condition management using evidence-based techniques. Patients receive one-on-one care from experienced therapists who combine manual therapy with movement retraining to promote long-term healing.
Manual Therapy
Manual therapy involves skilled hands-on techniques to improve joint mobility, relieve pain, and enhance tissue healing. Our therapists use methods like myofascial release, osteopathic mobilization, and muscle energy techniques to address musculoskeletal imbalances. This approach targets the root cause of discomfort rather than just symptoms.
Back and Neck Pain
We specialize in treating back and neck pain caused by poor posture, injuries, or degenerative conditions. Our therapists assess spinal alignment, muscle imbalances, and nerve involvement to create targeted treatment plans. Techniques include posture correction, spinal stabilization exercises, and nerve mobility interventions for lasting relief.
Balance and Stability
Our balance and stability program addresses vestibular disorders, post-concussion symptoms, and age-related balance issues. Therapists use sensory integration training and fall risk assessments to improve coordination. Customized home exercise programs help retrain the brain to maintain stability in various environments.
Bike Fit
The bike fit service analyzes cycling posture and biomechanics to enhance performance and prevent injuries. Therapists assess saddle height, handlebar positioning, and pedal mechanics using motion analysis technology. Adjustments improve efficiency while reducing strain on knees, hips, and the lower back during rides.
