The body doesn’t lie—when physiology changes, function follows.

Introduction
When we think about diabetes, we often picture glucose levels, insulin, and the classic complications—nerve damage, kidney disease, vision loss. But what if the condition also quietly reshapes how we move every day? A recent study by Petrovic et al. sheds light on a lesser-known consequence of diabetic neuropathy: impaired tendon mechanics, particularly in the Achilles tendon, during walking. This discovery doesn’t just add a new layer to diabetes management—it challenges how we approach rehab and movement training in these patients.

Function Follows Physiology
The Achilles tendon plays a vital role in walking by acting like a spring—storing elastic energy when your foot hits the ground and releasing it as you push off. But in individuals with diabetic neuropathy, this elegant process is disrupted.

Here’s what Petrovic’s study revealed:

• Increased tendon stiffness: Tendons are supposed to stretch and recoil, but stiffness limits that function, reducing fluid movement and shock absorption.
• Reduced energy storage and return: The tendon’s ability to act like a spring is diminished. Instead of rebounding with ease, it’s more like a rigid cable—less energy-efficient and less adaptive to movement demands.
• Higher hysteresis: More energy is lost as heat rather than being recycled into forward motion. This “energy leak” makes walking more fatiguing and less biomechanically efficient.
• Greater muscular workload: Because the tendon isn’t doing its job as a passive energy recycler, muscles have to work harder to compensate—resulting in quicker fatigue and reduced gait endurance.

Why It Matters in Rehab
These changes aren’t just biomechanical trivia—they have real implications for daily function and rehabilitation. Patients with diabetes may struggle more with walking not only due to neuropathy but because their tendons are working against them.

A few clinical considerations:

• Rehab plans should address muscle endurance and coordination since tendons can’t carry as much of the load.
• Incorporating eccentric loading and mobility-focused exercises may help improve tendon elasticity over time.
• Therapies aimed at improving metabolic health—like nutrition, glycemic control, and aerobic conditioning—may indirectly benefit tendon function.

Conclusion
Tendons may not be the first structure we think of when managing diabetes, but they are a crucial link in the movement chain. The phrase “function follows physiology” reminds us that even subtle metabolic changes can ripple through the body in profound ways. By better understanding and addressing tendon dysfunction in diabetic patients, we can design smarter, more supportive rehabilitation plans—ones that truly meet patients where they are, structurally and metabolically.

Improved Access to Chiropractic and Other Local Services Across Illinois

As of May 2025, the U.S. Department of Veterans Affairs (VA) has implemented a major policy change that could dramatically improve access to timely, high-quality care for veterans. This update eliminates a longstanding administrative hurdle that often delayed referrals to community-based providers—including chiropractors—despite agreement between the veteran and their VA clinician.

What Changed?

Previously, even if a VA provider determined that community care was in the best medical interest of the veteran, the referral required a second clinical review. This extra layer frequently caused delays, confusion, and even denial of services, preventing veterans from receiving needed care close to home.

With the new policy, VA providers can now directly refer patients to non-VA providers in the Community Care Network without unnecessary bureaucratic barriers. This applies when community care is deemed clinically appropriate and in the veteran’s best interest.

Why This Matters

• Faster access to care: Veterans can now get timely services from chiropractors and other specialists.
• Local options: Care can be delivered in community settings, reducing travel burden and wait times.
• Veteran and provider collaboration respected: Clinical judgment and patient preference now play a greater role in the referral process.

Who Benefits?

Veterans throughout Illinois—and across the U.S.—who need care outside the VA system now face fewer delays. This is especially important for chiropractic care and other specialties where community providers can often deliver faster, more accessible services.
