Lower Extremity Care That Treats the Whole Chain

Lower extremity conditions rarely stay isolated. A foot issue can be driven by the hip. A knee problem may come from the ankle. Plantar fasciitis can originate in poor glute function. The lower extremity works as an integrated chain from the pelvis to the floor, and when one part does not do its job, another part absorbs the consequences.

At Function Performance Sport Chiropractic in Oregon City, we treat lower extremity conditions with a full-chain approach. That means a thorough assessment of how you move, targeted treatment at the real source of your symptoms, and progressive rehabilitation that restores the strength and coordination you need to stay better.

The lower extremity functions as an integrated chain from the pelvis to the floor. Poor hip control creates knee problems. Restricted ankle mobility produces knee and hip compensations. Foot mechanics affect everything above. Treating one joint in isolation often misses what is actually driving your symptoms. Our integrated approach considers all of it, then targets the actual source.

I have been experiencing shoulder discomfort and elbow pain for over 10 months, nothing was sticking for me and I was almost completely ready to give up. I decided to give Function performance a call and even explained to the receptionist I wasn’t super convinced I could get better, she had told me this place had given her life back after 5 years of back problems, man she was right - I have only been going for about a month now, but my progress has been unbelievable thus far compared to any other alternative treatments and therapies I have had before. Ben is a super respectful guy, always greets me and shakes my hand when I arrive, nothing but positives from me here!

 Trustindex verifies that the original source of the review is Google. As a massage therapist who has seen many chiropractors over the years I can be picky, and I am very impressed with Dr. Ben. He has a large skill set and knowledge base, and can adjust his approach depending on what you need. I always feel better after seeing him and I always refer anyone I can to him.

 Trustindex verifies that the original source of the review is Google. Dr. Kyle and Dr. Ben are truly incredible. From helping my daughter recover from a cheer sports injury to supporting me after my car accident, their care has been life-changing for our family. What meant the most to me was how they approached my daughter’s recovery, they didn’t just pull her from the competition season. They created a modified training plan that allowed her to continue competing during the season while still treating properly. That balance made such a difference for her both physically and emotionally. I’ve also recommended them to my brother, who was dealing with a rotator cuff injury. His primary care doctor was already suggesting an MRI and possible surgery. After just three visits with Dr. Kyle, he’s nearly back to normal function—no surgery, no expensive imaging. I can’t recommend them enough. If you’re looking for thoughtful, effective care that truly prioritizes healing and quality of life, they are the best.

 Trustindex verifies that the original source of the review is Google. Dr. Ben is AMAZING. I’ve seen various chiropractors over the years for back and neck issues, but what sets him apart is his holistic approach. Adjustments, body work, rehab programming, and attention to detail. I feel so much better since I started coming to Function Performance. 10/10 recommend.

 Trustindex verifies that the original source of the review is Google. The entire team at Function Performance Sports Chiropractic is incredible. I've been working with Dr. Kyle for quite some time now and he's helped me through several challenges addressing injuries with more than just chiropractic work, but focused recovery exercises, shockwave therapy, and more. I was REALLY pleased recently to learn than they added Mika to the team. She is an incredible addition providing both relaxing and healing massage. She listens so well, asks great questions, and goes out of her way to make sure you have a positive experience. I can not say enough about the great service, support, and care I recieve every time I walk through those doors and get greeted by Sierra and/or Peace (and don't forget the friendly puppy who often walks me back to my appointment). What a phenomenal team!!!

 Trustindex verifies that the original source of the review is Google. I’ve been coming to Function Performance for almost two years and have consistently been impressed with the care and professionalism of the whole team. Dr. Kyle did an excellent job helping me rehab a bad ankle sprain so I could return to running. Mika has also been amazing and has helped me work through knee and hip pain so I can keep moving. Grateful for their support and expertise.

 Trustindex verifies that the original source of the review is Google. Nika is the massage therapist. She’s fantastic! So professional, caring and skilled. I get excited when it’s massage day! I know relief is on its way!! So grateful for Dr Ben and his professional staff. They get me in when I need help. Dr Ben spends as much time working my muscles and body as needed for me to feel a difference before I leave. Definitely recommend!
