John Gibbons is a world renown osteopath, he teaches physical therapy methods worldwide and is also the creator of the body master course. He also writes books to spread professional knowledge (can be bought on amazon). As someone who was examined by him, what I found was he would do an elimination and checklist strategy; this avoids misdiagnosis in 99% of the cases. He checks everything, nerves, strength, muscle length tests to really paint a perfect picture of what is going on to organise a treatment.
Extract From John Gibbons Book Vital Glutes
The research results of Janda (1983) indicate that tight (short) or overactive Short muscles not only hinder the agonist (opposing muscle) through Sherrington’s law of reciprocal inhibition as stated by Sherrington (1907) but also become active in movements that they are not normally associated with.
This is the reason why, when trying to correct a musculoskeletal
imbalance, you would encourage lengthening of an overactive (shortened) by
using a muscle energy technique (MET or PNF stretching), prior to attempting to
strengthen a weak elongated muscle.
A tight muscle will pull the joint into a dysfunctional position and
the weak muscle will allow this to happen, therefore we lengthen the short
before we strengthen the weak. For example, we would lengthen the shortened
pectoral muscles prior to strengthening the weakened rhomboids.
If muscle imbalances are not addressed, the body will be forced into a
compensatory position, which increases the stress placed on the musculoskeletal
system, eventually leading to tissue breakdown, irritation and injury. You are
now in a vicious circle of musculoskeletal deterioration as the tonic muscles
shorten and the phasic muscles lengthen.
Muscle imbalances are reflected in posture, as mentioned earlier,
postural muscles are innervated by a smaller motor neuron and therefore have a
lower excitability threshold. Since the nerve impulse reaches the postural
muscle before the phasic muscle, the postural muscle will inhibit the phasic
(antagonist) muscle, thus reducing the contractile potential and activation.
When muscles are subject to faulty or repetitive loading the postural muscles
shorting and phasic muscles weaken, thus altering their length tension
relationship. Consequently, posture is directly affected because the
surrounding muscles displace the soft tissues and skeleton. This leads to
altered movement patterns which cause compensation, pain and injury.
End of Johns Extract (you will be surprised how many therapists do not know this knowledge and instead make people’s situation worse by prescribing wrong treatment.
Common mistakes people make:
- A sensation of tightness does not always mean its tight a locked long muscle can feel tight too. (Muscle Length test is needed)
- When a weak muscle is found they don't check the opposing muscles for shortness, they just give strength exercises for weak muscle which won't solve issue if the opposing muscle is shortened. If it is , it must be stretched first every time before you try to strengthen the weakened. Aim is to correct altered reciprocal inhibition and length tension relationships.
