( If not why use anti- inflammatory treatment modalities ?) Add what is missing /create the environment. Self efficacy (The patient must understand and be educated in order to be expected to be compliant) 3 3/30/2017 TENSION (abnormal foot position or compensation for loss of flexibility . Surface of walking and running , shoe issues , weight gain. DOSAGE ( frequency , distance , speed or weight) Loss of lengthening of the Achilles complex/mechanical loss of dorsiflexion. (Tension) Eccentric weakness of the Achilles complex ( Tension) Excessive Prolonged Pronation (EPP). Think control versus motion . As we discussed in intrinsic stabilization . (Tension) Cavus foot type ( Tension ) Weight gain of obesity .( Tension and Dosage ) Change in running /walking volume (Dosage ) Change in walking /running surface (Dosage and tension ) 4 3/30/2017 Original description of this entity was Shoe gear (Tension /Shock ) “ Painful Heel “ Fatigue / prolonged standing ( Tension and Papers on this subject began to describe dosage ) inflammation being present , but there was no Proximal pronatory control weakness ( Hips as clinical .)histologic evidence that supports part of the Core ) inflammation as the underlying issue. Emerging evidence on intrinsic muscle “Itis” infers inflammation . Clinical signs of weakness / atrophy ( Chang 2012 ) inflammation: pain , heat , redness , swelling PLUS histologic findings( leukocyte accumulation macrophages ,lymphocytes , plasma and vessel proliferation ) Lemont H, Ammirati K, Usen N.

Of these 51 ruptures, 44 (86%) were associated with corticosteroid injection POST-STEROID NORMAL INJECTION 6 3/30/2017 Subjective /History : Examination ( Objective ) Pain located in the plantar heel ( not just pain Specific palpation of the calcaneal tubercle and somewhere in the foot ) along the plantar fascia middle/medial band .

AL . This article is a great review of the effects of immobilization as well as the effects of excessive tension on peri- articular soft tissues ( PAT ) . Peri-articular tissues are designed to withstand tensile stress. If tissue is deprived of tensile stress or there is excessive stress ,morphologic, biomechanical and biochemical changes occur . Loss of GAGs ( key components of connective tissue ), and water cause intermolecular and intramolecular cross links to form . This limits extensibility of tissue which further leads to degeneration . 10 3/30/2017 There is a loss of degradation / synthesis balance . Frost proposes the theory of “ minimally effective strain”…not too much and not too little This is the theoretical basis for the treatment techniques to follow . CHOICES Reduces pain with patients Use or don’t use ? with “get up and go pain. “ Short term effect ( van de ( Hawke2008 , Lynch Water2010/Van Lunen 2011 ) 1998 ) K tape /Rock tap : effective but for less time (Tsia 2010) Designed to reduce tensioning stress overload by Custom vs. Prefabricated ? compressing tarsals ( as would (Pfeffer 1999, Martin 2014 ) occur with girding intrinsic muscles ) and by creating a tripod foot with first ray plantar flexion.
