a chain of events culminating in a chronic
inflammatory disorder with abnormal
immunological reactions.
– Autoantibodies “Rheumatoid Factor”
5. Stage 2 destruction :
– Articular cartilage erode & tendons may
rupture.

35. • Treatment:
– Judicious splintage to prevent deformity.
– Topical skin preparations.
– NSAIDs.
– Surgery for unstable joints.
36. • Triad: polyarthritis, conjunctivitis &
non-specific urethritis.
•Synoivitis is due to abnormal
immune response to infection

urogenital or bowel
infection
Lymphogranuloma venereum

GUT.
Shigella, Salmonella &
Yersinia enterocolitica in GIT.

• Abnormality of ”sensory processing” i.e. ”low pain
threshold”.
• Activation of stress responses by sudden

– Physiotherapy & daily exercise.
– Injections into painful areas.
– Psychotherapy.
Editor's Notes
LOM: limitation of motion
Spine Mobility: Assessment Description:Occiput-to-wall distance (left): The patient places his or her heels and back against a wall and attempts to touch the wall with the occiput, keeping the chin horizontal. The distance in cm from the wall to the tragus is measured. Fingertips-to-floor distance (center): With straight knees, the patient bends forward to touch the floor. When in fullest flexion, the distance b/w fingertips &floor is measured in cm. Chest expansion (right): Measurement is taken at max. expiration & then at max. inspiration at the 4th ICS (nipple line); however, other areas may be used as long as the measurement is consistent over time. The patient should stand with hands on head. The best of three efforts should be recorded in cm. The difference b/w max. exhalation & max. inhalation should be 7 - 12 cm. Less than 3 cm is abnormal.
