Comparing hamstring activity with three different kettlebell swings

I found this paper, Hamstring Myoelectrical Activity During Three Different Kettlebell Swing Exercises.  

The paper compared how 3 different swings, the hinge swing, the squat swing, and the double knee extension swing (used in those who train for kettlebell sport) affected the hamstring muscles. The 3 hamstring muscles were divided into 2 parts a medial part (semitendinosus and semimembranosus) and the lateral part (biceps femoris).

What they found was that for all three swings the medial hamstring worked more than the lateral hamstring.  They also found that the hinge swing produced the most hamstring muscle activity throughout the entire movement compared to the other swings.

What this means is that when a person is rehabilitating a hamstring strain we may want to progress from a swing that produces less strain to one that produces more.

 

A Spinal Manipulative Therapy or Lumbar Nerve Root Injections comparative study

Herniated discs, especially those that result in pain down the leg are troubling for  athletes, weekend warriors or just the regular Joe/Jane.  I am sure there are people who avoid seeing a chiropractor because they have been told that they have a herniated disc. They have been told by others that a chiropractic adjustment would make them worse and to not go see one.

I treat people with herniated discs, sciatic, and back pain every day.  This is what I treat the most in my practice.  Spinal Manipulative Therapy, the chiropractic adjustment,  is often a part of a person’s treatment.  It does help and this paper shows that. The paper even shows that spinal manipulation has similar effects to medical procedures.

Chiropractic care helping the medical system

This is how Chiropractic care an help with the medical system.  We can help take the stress off of the medical system in Canada for those with headaches, back and neck pain.  In the USA, we can find Chiropractors in the hospitals, working along side medical doctors. I would love to see the day that we could work along side each other to help our mutual patients.

This study was performed in the United States so the numbers would not be the same but the evidence shows how Chiropractic care can help reduce the stress and burden on the medical system.

Collectively, these studies suggest that coverage of chiropractic care among adults is associated with reduced spending on medicine and use of diagnostic tests in the population with private insurance.

Efficacy of Spinal Manipulation for Chronic Headache: A Systematic Review

Found this systematic review on spinal manipulative therapy (SMT) and chronic headaches.  Though the authors note that the research isn’t based on strong studies this is their conclusion:

SMT appears to have a better effect than massage for cervicogenic headache. It also appears that SMT has an effect comparable with commonly used first-line prophylactic prescription medications for tension-type headache and migraine headache. This conclusion
rests on a few trials of adequate methodological quality. Before any firm conclusions can be drawn, further testing should be done in rigorously designed, executed, and analyzed trials with followup periods of sufficient length.
