what pathway is pain through & how is it testedlateral spinothalamic tract; test with sharp-dull ad pinprick test
test moving touchwith 2 point discrimination test
test measuring threshold levels of sensory receptorsSemmes-Weinstein Monofilament test
goal of sensory reeducatonmaintain/restore cortical hand representation and regain use of sensation of the hand
phases of sensory reeducation1: preserve cortical representation (positioning, open-close movements, massages, elevation, work with eyes closed and perform mental practice, alternative senses used); Phase 2 happens when able to feel deep touch and moving touch (eyes closed open closed procedure through 5 stages)
deep and moving touch happent through which tractanterior spinothalamic tract
5 stages of phase 2 of sensory reeducation1. object recognition using feature detection 2.prehension with refined prehension pattern 3.control of prehension force while holding objects 4.maintain prehension force during trasnfer 5.object manipulation
common damage from no protective sensation1. continuous pressure (frequent position changes and cushions) 2.concentrated high pressure (careful strategies) 3.excessive heat/cold (awareness) 4.repetitive mechanical stress (avoid friction and high repetitions) 5.pressure on infected tissue (edcuate on skin care)


Question Answer
untreated pain may lead tolow effective vascular circulation, high oxygen needs, compromised immune system, high risk for venous thrombosis/pulmonary embolism
painful diagnosis with no clear explanation, sympathetic NS is involved (in thoracic spinal cord region)complex regional pain syndrom (CRPS)
types of CRPS type 1 (no known n. injury) or type 2 (direct n. injury); or can be blocked SNS or nonblocked SNS (blocking SNS either helps or doesnt)
interventions for CRPSmust get movement through extremity, bilateral activities/ADLs, TENs, mirror therapy, placebo treatments
physical illness that can't be explained by organic disease and no structural lesion/biomechanical changefunctional somatic syndrome
symptoms are out or proportion to the impairment (but not conscious and unintentional)somatoform disorders (such as hypochondriasis, body dysmorphic disorder, conversion disorder)
have symptoms without objective medical evidence of impairment (occurs frequently)somatization disorder
fatigue not explained, longer than 6 months, know definit onset time, and low activity level not from exertion (and not relieved with rest)chronic fatigue syndrome
