Section 1

Question Answer
Define TendinitisInflammation of a tendon.
Define Loading in relation to tendonsA load on a tendon causes the collagen fibers to straighten causing temporary deformation. Accounting for 4% of the increase in length.
What happens when a tendon load is less than 4%?Nothing, tendon reverts back to normal shape/size.
What happens if a tendon's load is greater than 8%?Collagen links begin to fail, causing microtearing, partial tearing, and complete rupture.
Define Chronic overload in relation to tendons.Excessive load leading to microtears and inflammation.
What are some contributing factors to chronic overloading of tendons?Muscle imbalances, poor biomechanics, lack of flexibility, chronic degenerative changes in tendon, poor blood supply and improper equipment/training errors.
Define Grade 1 tendinitisPain during activity only.
Define Grade 2 tendinitisPain at beginning and end of activity.
Define Grade 3 tendinitisPain at beginning, during and after activity. May limit activity.
Define Grade 4 tendinitisPain with ADL's that gets progressively worse.

Section 2

Question Answer
What is ParatendinosisInflammation of the paratendon or tendon sheath. Irritated when rubbing against bony prominences.
What is TenosynovitisIrritation of the inner surface of tendon sheath.
What is TenovaginitisIrritation and thickening of the sheath itself.
Define TendinosisDegenerative changes with overuse. May progress to microtearing, partial or complete rupture. May begin with acute inflammation that passes. No signs of inflammation in tendon, though biopsy shows damage to tendon that causes pain.
What other pathologies are/can be related to tendinitis?Impingement syndome- inflammation/edema/pain in tissues within coracromial arch. Rotator Cuff tears, overuse/impingement/aging to rotator cuff muscles. (especially supraspinatus)

Section 3

Question Answer
What are the three progressive stages of impingement?Stage 1- edema and hemorrhage of subacromial bursa. Stage 2- Tendinitis and fibrosis, reversible with conservative care. Stage 3- Incomplete tears or complete ruptures. Surgery usually req'd.
What symptoms are seen in acute tendinitis?Gradual onset of local tenderness for one to two days post activity, initially pain diminishes with continued activity, progressive pain with increasing severity, microtearing with adhesion formation, inflammation, heat, swelling, crepitus possible, reduced ROM.
What symptoms are seen in chronic tendinitis?Pain during and after activity, chronic inflammation, fibrosis and adhesions present, chronic swelling + thickening, crepitus possible, reduced ROM + strength, acute flareups with overuse, tendon degeneration and possible rupture.
