We are always talking about compensations. We have worn out our statement “what you see in someone’s gait is not their problem, ti is their compensation stratetgy(s).”
Here is a study with an interesting thought.
Just remember, try to fix the underlying problems. But, realizing sometimes you cannot, especially in the elderly population, sometimes you have to give a strategy to help them even though it is not the solution you want. And remember also that driving the anterior compartment with appropriate exercises as our “shuffle walk” might stop any loss of ankle dorsiflexion that might be met with the extra calf work that this article seems to suggest.
From the study: “ Of particular importance were the compensatory mechanisms provided by the plantar flexors, which were shown to be able to compensate for many musculoskeletal deficits, including diminished muscle strength in the hip and knee flexors and extensors and increased hip joint stiffness. This importance was further highlighted when a normal walking pattern could not be achieved through compensatory action of other muscle groups when the uniarticular and biarticular plantar flexor strength was decreased as a group. Thus, rehabilitation or preventative exercise programs may consider focusing on increasing or maintaining plantar flexor strength, which appears critical to maintaining normal walking mechanics.”

The motion needs to occur somewhere…Make sure you look at the whole picture
Since the knee was bent, perhaps we should be looking at the soleus? And the talo crural articulation?

GOT GLUTE MEDS?
Want to strengthen that gluteus medius we were talking about Monday? Have you considered walking lunges with dumbbells? These seem to activate the side contralateral to a better extent than split squats.
We wonder if you get the same effect with a medicine ball. Anyone out there have some data or experience with that?

We all see people with patellofemoral pain. Some of those cases may have responded to orthotic therapy. Some studies show that the effects on frontal plane kinematics are minimal (1 degree); this doesn’t mean it didn’t work, or this amount is not clinically significant. So why do they help? Perhaps it is a “timing” issue and the knee abduction moment.
“Our results are consistent with a 2003 study by Mundermann et al that compared the effects of custom orthoses (with posting, molding, or a combination of both) to flat inserts. For each orthotic condition, these authors reported a significant delay in the timing of the peak knee abduction moment. This finding may be related to the aforementioned clinical effects, as delaying the peak knee abduction moment would effectively decrease the rate of loading at the knee joint. The rate of loading has been previously implicated as a possible contributing factor in running-related overuse injuries, as runners with a history of injury have demonstrated a higher rate of loading of the vertical ground reaction force than runners with no history of running-related injury.”
This is an interesting take. If you have a few moments, give it a read:

It makes sense…but which came 1st?
Just make sure you ask your foot patients about their back, and your back patients about their feet

Just because it looks good, doesn’t mean that it is.
We have all had patients with seemingly negative knee x rays and pain, only to develop arthritic changes at a later date. Find and treat the cause!
“Our analysis found that incident radiographic knee osteoarthritis is preceded by prodromal symptoms lasting at least 2-3 years. This has potential implications for understanding phasic development and progression of osteoarthritis and for early recognition and management.”
