Low back pain (LBP) is the second most common symptom-related reason for clinician visits in the United States (skin disorders was number one) and is THE most common indication for Chiropractic care. In fact, up to 84% of the US population has been found to report LBP symptoms at some point during their lifetime. However, the etiology of LBP is not well understood considering the evidence that people without LBP have structural changes and many LBP patients have no structural changes on imaging studies of the lumbar spine. Long and colleagues performed a standardized mechanical assessment on 312 patients with LBP, with and without sciatica. They were able to successfully subgroup 230 (74%) of these patients, however 26% of the patients did not fit into a subgroup   (Long A, 2004). So, the question remains: how do health care providers best assess people with LBP in order to develop a specific and successful treatment recommendation? Might we look beyond the spinal column for the source of, or contributor to, pain and loss of function?

Research now shows that limited hip internal rotation can significantly contribute to low back pain. This may be caused by hip joint variants but more commonly by trauma causing adhesion of the hip joint capsule or even prolonged sitting which over activates the hip flexors and abductors and under activates the hip extensors and adductors. This article explores the relationship between hip mobility and lower back health, highlighting how restricted hip internal rotation can lead to various issues in the lumbar spine. 


Biomechanics

Hip internal rotation plays a crucial role in normal gait, balance, and functional movement. When this range of motion becomes restricted, it forces compensation in other parts of the body, particularly the lumbar spine (Sadhegisani, 2015). This compensation can lead to several problems:


Lumbar Over-rotation: Reduced hip mobility causes the lumbar spine to over-rotate during everyday movements, increasing pressure on intervertebral discs, muscles, and ligaments.

Pelvic Dysfunction: Limited internal rotation, especially when asymmetrical, can cause pelvic imbalances that pull the lower spine into abnormal positions.

Altered Biomechanics: The lack of hip internal rotation changes overall movement patterns, altering the natural biomechanics of the spine and pelvis.


What Does the Research Say?

The correlation between limited hip internal rotation and low back pain is elucidated in many recent studies. Sadhegisani reported that asymmetrical and limited hip internal rotation ROM were common findings in patients with LBP. Reduced and asymmetrical total hip rotation was also observed in patients with LBP. However, none of the studies explicitly reported limited hip external rotation ROM. Proving that not all hip rotation ROM affects low back pain, just internal rotation. 

Ellison et al. reported that deficits in hip internal rotation are related to both LBP and sacroiliac joint pain (JB, 1990). Another study found that patients with low back pain and positive hip findings such as a positive anterior hip impingement test, FABER test, and/or log-roll test, have more pain and worse function compared to those without positive hip findings. Research has also demonstrated that a loss of hip internal rotation can prevent the pelvis from rotating properly over the stance limb during gait, affecting the coupling mechanics of the sacrum and lumbar spine (Yoon, 2024).


What Causes Hip-related Low Back Pain?

The development of low back pain due to limited hip internal rotation can occur through several mechanisms such as compensatory spinal motion, pelvic and lumbar muscle imbalances, and repetitive stress syndrome (Sadhegisani, 2015). When hip rotation is limited, the spine may compensate by rotating, extending, or flexing more than it should. Restricted hip mobility can lead to muscle imbalances through overactivity and tightness related muscles such as the piriformis, potentially compressing the sciatic nerve. Repetitive stress injuries also come into play. Even small amounts of repeated rotation in the spine, compensating for lack of hip mobility, can produce microscopic injuries to spinal structures over time.


How to Make the Diagnosis

Limitations in hip internal rotation can be diagnosed through several assessments such as:

Seated Test: The patient sits on the edge of a treatment table with feet dangling, knees and hips flexed to 90 degrees. They are asked to keep their knees together while moving their ankles apart. The Chiropractor may apply overpressure to add a passive component.

Prone Test: With knees together and flexed to 90 degrees, the ankles are allowed to fall apart. Overpressure can be applied for a passive component.

Gait Observation: While assessing gait you may notice movement compensations such as overpronation of feet, knee valgus, reduced step length, external rotation of the foot during stance phase, increased lumbar and knee extension. 


How to Correct 

To correct limited hip rotation, it is best to use a combination of hip joint mobilization, stretches, and strengthening exercises. Joint play assessment with mobilization in the direction of limited movement through manipulation and hip scouring techniques as well as soft tissue mobilization to the ipsilateral psoas, glute medius and piriformis muscles are a great place to start. Followed by hip stretching and strengthening exercises such as:

Twisted Legs Hip Internal Rotation: Sit on the ground, let both knees fall to one side, and place the top foot on the opposite knee.

Seated Hip Internal Rotation: Sit with knees at 90 degrees, flex one foot, and turn the inner thigh toward the ground. Perform 20-30 reps per side.

90/90 Hip IR Lift Offs: In a 90/90 position, lift the back leg while focusing on internal rotation.

Step Across: In a staggered stance, step across the midline with the back foot while keeping the front leg still. Repeat 20 times.

Band Lateral Distraction IR Rockbacks: Seated patient uses a band for lateral distraction while rocking and maintaining internal rotation of the hip against resistance, focusing on keeping a flat back.

Swivel Chair (not pictured): This is a great stretch your patients can do right in their office. Place your knee on a swivel chair and swing your foot outward, keeping the pelvis still. Repeat 20 times. 


By incorporating hip internal rotation assessment into their evaluations, chiropractors can develop more effective and comprehensive treatment strategies that address both spinal and hip dysfunction as a cause of low back pain, leading to improved patient outcomes and long-lasting relief.

Low back pain is something nearly everyone experiences at some point in life. In fact, research estimates that up to 80% of adults will deal with low back pain, making it one of the leading causes of disability worldwide. When back pain becomes chronic, many people wonder: "Should I just strengthen my core?" Or... "Can I still lift weights?" A recent randomized controlled trial suggests the answer may surprise you. The Study Researchers followed adults with chronic low back pain for 12 weeks . Everyone participated in a weekly rehabilitation exercise class. However, half of the participants also completed one additional 45-minute whole-body strength training workout each week using resistance machines. The researchers wanted to know if adding full-body strength training would improve: Pain Strength Function Pain sensitivity compared to rehabilitation exercise alone. The Results Both groups reported improvements in pain over time. But the group performing whole-body strength training experienced several additional benefits. They demonstrated: Increased trunk (core) strength Reduced sensitivity to pressure over the low back Continued pain improvements one month after the program ended Perhaps most importantly, the researchers found that stronger trunk muscles were associated with lower pain sensitivity. What Does "Pain Sensitivity" Mean? Pain isn't always about damaged tissue. When someone has chronic low back pain, the nervous system can become more sensitive over time. Think of it like a car alarm that's become overly sensitive. Instead of only going off when someone hits the car, it starts sounding because of rain or wind. The same thing can happen with chronic pain. Normal movement begins to feel painful even though the tissues themselves may be healthy. The study found that whole-body strength training helped decrease this sensitivity, suggesting it may positively influence how the nervous system processes pain—not just strengthen muscles. Why Whole-Body Strength Matters Many rehabilitation programs focus almost entirely on "core exercises." While core stability remains important, your spine doesn't function in isolation. Everyday activities require your entire body to work together. Whether you're: Carrying groceries Lifting your child Playing golf Gardening Returning to the gym Working a physically demanding job your hips, legs, shoulders, and trunk all contribute to protecting your back. Improving total-body strength allows these muscles to share the workload, reducing unnecessary stress on the lumbar spine. Does This Mean Heavy Lifting Is Safe? For many people—yes. When appropriately prescribed and progressed, resistance training is considered one of the recommended treatments for chronic low back pain. That doesn't mean jumping into maximal deadlifts on day one. Instead, it means gradually building strength with exercises matched to your current abilities and goals. Movement Is Medicine One of the biggest messages from this study is that avoiding movement isn't usually the answer. Many people with chronic back pain become fearful of bending, lifting, or exercising. Unfortunately, prolonged inactivity often leads to: Muscle weakness Deconditioning Reduced confidence Increased stiffness Greater pain over time A structured strengthening program helps reverse that cycle. How Occupational Therapy Can Help At Thrive Sports & Spine, occupational therapy isn't just about reducing pain—it's about helping you return to the activities that matter most. Treatment may include: Progressive strengthening Functional lifting mechanics Core stabilization Mobility exercises Balance training Manual therapy Activity modification Home exercise progression Rather than avoiding movement, we help you build confidence so you can safely return to work, exercise, hobbies, and everyday life. Chiropractic Care Can Complement Strength Training Joint stiffness can contribute to altered movement patterns and muscle compensation. Our chiropractors work alongside occupational therapy to restore mobility where needed, allowing strengthening exercises to be performed more comfortably and efficiently. Acupuncture May Help Manage Chronic Pain For patients whose pain limits exercise participation, acupuncture may help: Reduce pain Decrease muscle tension Improve relaxation Support recovery between therapy sessions This can make it easier to stay active while progressing through rehabilitation. The Takeaway For years, chronic low back pain was often treated with rest. Today's research tells a different story. This study suggests that adding whole-body strength training to a rehabilitation program can improve trunk strength and reduce pain sensitivity, while also supporting meaningful improvements in chronic low back pain. The goal isn't simply having a "strong core." It's building a stronger, more resilient body that allows you to move with confidence again. Ready to Get Stronger?

Running is one of the easiest and healthiest forms of exercise. Whether you're training for your first 5K or your tenth marathon, running improves cardiovascular health, strengthens bones, and boosts mental health. Unfortunately, it also comes with a downside. Research shows that 25-30% of all running-related injuries occur at the knee , making it the most commonly injured joint in runners. The good news? Many of these injuries are preventable.  What Causes Running Knee Injuries? A recent systematic review analyzed 20 different studies involving endurance runners to identify what consistently increases the risk of knee injuries. Instead of finding one single cause, researchers discovered that knee pain usually develops from multiple factors working together. The three biggest risk factors were: Previous knee or running injury Training too much or progressing too quickly Biomechanical factors (how your body moves while running) The Biggest Predictor: Previous Injury One of the strongest findings from the review was that runners who had been injured before were much more likely to get injured again. Why? After an injury, many runners return to training before they've fully recovered. Even if the pain is gone, there may still be: Muscle weakness Poor balance Reduced flexibility Changes in running mechanics Decreased shock absorption Without addressing these issues, the body often compensates, increasing stress on other joints and tissues. More Miles Isn't Always Better Many runners believe that more training automatically leads to better performance. Not necessarily. The review found that rapid increases in weekly mileage, longer training hours, and higher overall training loads consistently increased the risk of knee injuries. Your body needs time to adapt. When muscles, tendons, and joints don't have enough recovery time, repetitive stress begins to build faster than your body can repair it. This is when overuse injuries begin to develop. Running Form Matters Researchers also found that movement patterns can influence injury risk. Some runners demonstrated: Increased pelvic tilt Poor hip control Excessive trunk lean Abnormal knee loading Reduced shock absorption These movement patterns may place additional stress on structures around the knee, especially during longer runs. It's important to remember that there is no single "perfect" running form. Instead, the goal is to identify movement patterns that may be contributing to your specific pain. Common Running Knee Injuries The review highlighted three conditions that occur most often. Patellofemoral Pain Syndrome (Runner's Knee) Often felt around or behind the kneecap. Pain usually worsens with: Running hills Stairs Squatting Sitting for long periods Contributors include poor hip strength, altered mechanics, and training errors. Iliotibial Band Syndrome (IT Band Syndrome) Pain develops on the outside of the knee. This condition is commonly associated with: Increased training volume Hip and pelvic control deficits Running biomechanics Previous injury history Patellar Tendinopathy (Jumper's Knee) Pain occurs just below the kneecap where the patellar tendon attaches. Risk increases with: High training volume Tight hamstrings Previous knee injury Poor load management How Occupational Therapy Can Help At Thrive Sports & Spine, occupational therapy focuses on helping runners return to the activities they love. Treatment may include: Strengthening weak hips and legs Improving flexibility and mobility Addressing balance and stability deficits Correcting movement patterns during functional activities Building a gradual return-to-running program Reducing pain while improving performance Rather than simply treating symptoms, we work to identify why the injury developed in the first place. Chiropractic Care Can Improve Movement Restricted joints can alter the way forces travel through the body while running. Our chiropractors evaluate spinal, pelvic, and lower-extremity mobility to help restore efficient movement and reduce unnecessary stress on the knees. Acupuncture Can Help Manage Pain For runners dealing with persistent soreness or overuse injuries, acupuncture may help: Reduce pain Decrease muscle tension Promote relaxation Support recovery between training sessions Prevention Is Better Than Recovery The biggest lesson from this review is that most running injuries don't happen because of one bad run. Instead, they develop gradually through a combination of previous injury, excessive training, and movement patterns over time. If you're preparing for a race—or simply enjoy running for fitness—taking the time to improve strength, mobility, and recovery can help keep you healthy for miles to come.

Many people think chronic low back pain is simply caused by sore muscles or a "bad back." However, new research suggests that long-lasting back pain affects much more than the spine. It can change how your body processes pain, reduce your physical fitness, and even impact your mental well-being. What Did the Study Find? Researchers compared adults with chronic low back pain to healthy individuals to better understand how pain affects the body. They discovered that people with chronic low back pain had: Higher levels of anxiety and depression More pain catastrophizing (expecting the worst from pain) Greater signs of pain sensitivity, also known as central sensitization Reduced walking endurance during a 6-minute walking test The researchers also found that pain sensitivity and psychological stress explained about 60% of the differences in walking ability , showing that chronic pain affects much more than just the muscles and joints. Your Nervous System Can Become More Sensitive When pain lasts for months, your nervous system can become overly sensitive. This process, called central sensitization , means your brain and spinal cord begin to amplify pain signals. As a result: Normal movements may feel painful. Minor aches can feel much worse than expected. Pain may continue even after tissues have healed. This helps explain why many people continue experiencing back pain even when imaging shows only mild changes. Chronic Pain Can Affect Your Fitness The study found that individuals with chronic low back pain walked significantly shorter distances than healthy adults. This often happens because people begin avoiding movement due to fear of pain. Unfortunately, less movement can lead to: Muscle weakness Reduced endurance Poor conditioning Increased stiffness Greater disability over time The good news is that safely increasing movement can help reverse this cycle. Your Mind and Body Work Together One of the biggest findings from this research is that psychological health and physical health are closely connected. People experiencing more: Anxiety Depression Fear of movement Pain catastrophizing also tended to have poorer walking performance and greater pain sensitivity. This does not mean the pain is "all in your head." Instead, it shows that chronic pain is influenced by both the body and the nervous system. Treating only one piece of the puzzle often isn't enough. How Our Team Can Help At Thrive Sports & Spine, we use a team-based approach to address the many factors contributing to chronic low back pain. Occupational Therapy (OT) Our occupational therapists help patients: Restore strength and endurance Improve movement patterns and body mechanics Increase walking tolerance Reduce fear of movement through graded exercise Return to work, hobbies, exercise, and everyday activities safely Chiropractic Care Our chiropractors help improve: Joint mobility Spinal mechanics Overall movement efficiency This can decrease stiffness and improve how the body moves throughout the day. Acupuncture Acupuncture may help: Reduce pain Calm an overactive nervous system Improve relaxation Support the body's natural healing process Medical Providers Our medical team can: Evaluate persistent pain Rule out underlying medical conditions Coordinate medications or additional treatments when appropriate Ensure you're receiving the right care at the right time The Best Results Come From Treating the Whole Person This study reinforces an important message: Successful treatment of chronic low back pain goes beyond treating the spine alone. By improving: Strength Endurance Movement quality Pain sensitivity Confidence with activity patients can often move with less pain and enjoy a higher quality of life. Don't Let Chronic Back Pain Control Your Life If you've been living with back pain for months—or even years—you don't have to simply "learn to live with it." Our multidisciplinary team works together to identify the factors contributing to your pain and create a personalized treatment plan that helps you: Move better Feel stronger Reduce pain Improve confidence Get back to doing the activities you enjoy Every journey starts with a comprehensive evaluation and a plan tailored specifically to your goals.

Heel pain can make even simple activities like walking the dog, exercising, or standing through a work shift uncomfortable. One of the most common causes of heel pain is plantar fasciitis, a condition involving irritation of the thick band of connective tissue that supports the arch of your foot. While many people improve with stretching, supportive footwear, and activity modification, others continue to experience pain for months despite trying multiple treatments. A recent study published in the Journal of Clinical Medicine examined how radial extracorporeal shockwave therapy (ESWT) affects patients with chronic plantar fasciitis that had not responded to conservative care.
