It was once thought that chiropractic increased muscle strength by reducing weakness secondary to pain. This theory has been proved true.

Since then, research has also shown that after a chiropractic adjustment, even those without pain get gains in muscle strength!

This research has shown that chiropractic literally charges the brain, which is the power source to muscle, and therefore increases muscle strength - no matter if you are in pain or not.

Who should care about this?

Here’s a list of what this means to you by age group:


A baby with low muscle tone can have the following problems:

  • Difficulty breastfeeding due to:
    • Poor / weak latch
    • Falling asleep before finished feeding
    • Taking forever to feed or frequent ‘snacking feeds’ (feeding all day)
  • Poor Tummy time endurance
  • Delayed milestones of development
  • Open mouth breathing / snoring


  • Feet rolling in and knocked knees
  • Clumsy (more than a usual toddler)

Teenager and Adult:

  • Performance: If you’re an athlete you’ll want your muscles to be getting full voltage of power for optimal performance.
  • Posture: poor connection between your brain and body leads to poor posture


  • Improved Balance and Decreased Risk of Falls
  • Seeking a prolonged active high quality of life.
