![]() If in pain, pressure on the TrP will invariably recreate your pain (which maybe in a completely different place to where pressure is applied). However clinical experience makes me and many, many other professionals believe Trigger Point therapy can affect pain (relief) in a mechanical and neurological way – one cannot treat/affect one without the other – and is part of the biopsychosocial approach to successful treatment of pain and dysfunction. This is only a theory that has been strongly refuted by some researchers and clinicians claiming the effects are purely neurological and/or placebo. Localised tension pressure in and around a nodule or ‘knot’ can create a “energy crisis” meaning starvation of oxygen and accumulation of waste products within the muscle fiber, without innervation from motor units (nerve signals). TrPs can be active (producing pain) OR latent (no pain) but will always be self-perpetuating to some degree – depending on how long the TrP has been activated. Travell & Simons hypothesized that trigger points occur when muscle fiber sarcomeres are either acutely, sustained and/or repetitively overloaded. Within muscles are thousands if not millions of microscopic muscle fibers which contract independently to make a muscle/joint move. A trigger point (TrP) was first defined by Dr Travell & Dr Simons as “a highly irritable localized spot of exquisite tenderness in a nodule in palpable taut band of muscle tissue”. ![]()
