Tightness & Hypertonicity occur to most people and dogs at some point in their lives. If your dog is living with a pre-existing condition, such as an orthopaedic condition or muscle injury, these two conditions can make hypertonicity worse as the range of motion is restricted, furthering pain and inhibiting movement and mobility.
Refers to a muscle resting length. Tightness can also be seen as stiffness and lack of range of motion when a dog is on the move. Tightness will over-excite sensory receptors called Muscle Spindles which are responsible for detecting changes in the length of the muscle. When the muscle is tight the fascia becomes abnormal as it begins to tighten, stopping normal muscle function and producing nociceptive pain.
A tight & hypertonic muscle is a sick muscle…
- Prone to injury i.e. a strain
- Uncomfortable on a daily basis
- Can be worse after rest and loosen up after exercise
- Dull aching chronic pain
- Formation of trigger point with associated referral papters
- Cause deviations in normal posture
