At Reaction Physical Therapy in Arlington, WA, your Physical Therapist will create an individual therapy program that is specifically developed for you based on a complete evaluation of your condition. Our rehabilitation philosophy is to promote healing through a combination of exercise and manual therapy, as well as to educate our patients in injury prevention, body mechanics and self-help techniques. We aim to provide you with the best physical therapy in Arlington.

We work with each individual patient and their physicians to design a treatment program that fits their lifestyle to ensure that our patients have the best possible outcome. The ultimate goal is for you to return to normal activities of daily living, work and participation in sports or recreational activities. Our treatment approach first focuses on decreasing pain, edema and muscle guarding to improve joint motion.

As you improve, your exercise program will progress to fit your needs for coordination, balance, endurance and strength training. You can expect your physical therapy experience to be unique, one on one and allow you to meet your individual goals. We are able to assist you with transitioning from exercise for rehabilitation to exercise for health maintenance, cardiovascular improvement, return to work and/or enhanced athletic performance.

Same Day Appointments Available.  Call to schedule today (360) 363-4246.

– Custom Orthotics –

Orthotic devices are used to alter or modify foot function. They are designed to treat, adjust, and support various biomechanical foot disorders, aches and pains. The most effective orthotics are custom-made and are crafted to meet the specifi c needs of a particular individual. Custom orthotics are created using a cast of the foot to replicate the exact shape and contour. Your PT will determine misalignments in foot structure, directing the orthotic lab to make adjustments to improve function and support.. The finished orthotic keeps the foot properly aligned by eliminating abnormal biomechanics. Depending on the need, the orthotic can be customized with padding or dimpled for relief points around spurs

 – Gait Analysis –

Repetitive training such as running and cycling, often lead to muscular strength and flexibility imbalances. An example of this would be a cyclist’s quadriceps muscles becoming highly developed, and the smaller stabilizing muscles becoming weak in comparison. Similarly, this imbalance can exist in terms of flexibility, where a runner’s calves and hamstrings become very tight and strong while the quadriceps becomes relatively weak. Persistent training can drive these imbalances to the point of injury.

A gait analysis will help identify imbalances of alignment, flexibility and strength. Specific stretches and strengthening exercises may be recommended to help minimize and correct these imbalances. Walking and/or running gait will be assessed, and advice on running shoe selection will be offered.
