Description
Week 7 What are normal movement patterns in an atypical population  Misconception that deviation from normal movmt pattern in unimpaired pop. Are wrong + need correcting, question is are they actually wrong, and which ones  Movement spectrum (clumsy vs elite athlete) different motor patterns for specific sports  What is normal? If the task is completed successfully isn’t that normal?  Motor task  understanding  control patterns + coordination execution  Involves understanding, time, control variables, reflexes + muscle tendons and external forces  Priorities, task, enviro, structure  control patterns  mvmt patterns  Any changes can impact whole mvmt  CNS elaborate new patterns to take changes into account, may be able to perform normally but prefer a different way (Christine could walk with braces but preferred wheelchair)  Limb amputation leads to biomechanical + neurophys disruptions, changing of pattern that had been lifelong dvlped, change in which muscles produce E and absorb E  Parkinson’s = tremor (alternating activity of antagonist of ms controlling a joint), bradykinesia (slow voluntary mvmts + difficulty initiating), rigidity (sustained increase in resistance to externally imposed mvmt), decreases postural reflexes (poor anticipation in postural changes)  Decrease target size + increase target distance = increase time mvmt + reaction  Dystonia – supraspinal pathology w/o gross anatomical or neurophys changes  Hesitations, reversals, may be imbalance with descending signals  Walking patterns may be consequence of unstable head  Motor mvmts in down syndrome often addressed as clumsiness, less effective looking, slowness and inability to adopt to changing enviro  Proximal to distal order mvmt is more efficient, viewed as normal Physical activity of adults with mental retardation  Increased rates of mortality and morbidity with hypoactivity (in mental R populations)  Increased bp, diabetes, obesity rates, decreased physical fitness  Indivs express want for control over life, activity would increase self-dependence/control  Physical activity = skeletal muscle mvmt that increases energy expenditure  Exercise = type of p.a that is planned/structured, purpose to increase fitness  Fitness = set of attributes related to ability to perfom p.a  Less than 1/3 engaed in recommended 30min/most days a week Barriers/Facilitators Demographic/biological Social/Cult Psych/cog/emo - education (+) - restriction (-) - time (+) - age (-) - center (+) - money (+) - behaviour probs (-) - Structure at home (+) - better appearance with p.a - health probs (-) - staff encouragement (+) - rewards (+) - transportation (+)
