Analyzing Variation Where Does it Come From?
Studies of Righting • Rising to Standing • Older Adults (Luehring) • New Patterns Discovered • Apparent Regression • Activity Level makes a difference • Teenagers (Sabourin) • Symmetry incidence peaks in middle teen years • Middle Aged Adults (Cromwell, Deo, et al) • Patterns related to body dimensions
Studies of Righting • Rising to Standing • Infants (Schiarappa) • New Movement Patterns Added • Developmental Sequences Validated • Later Childhood (Maracheski, et al) • Body Dimensions make a difference
Studies of Righting • Special Populations • Down Syndrome Children (Coleman, et al) • Developmental Delay within component action • Body dimensions may be the issue • Children with Visual Impairments (Lee, et al) • Developmental Delay in component action • Vision effects incidence of movement patterns used
Studies of Righting • Special Populations • Adults with Moderate and Severe Brain Injury • Recovery follows a “developmental sequence” • Balance is a factor in rising: fractionated movement • Women who are pregnant (Zapotchny, et al) • Body topography makes a difference • Young adults with traumatic BK and AK amputations (Carter, et al) • Those with AK amputation demonstrate early appearing patterns • Those with BK amputations demonstrate age appropriate patterns
Studies of Righting • Special Populations • Adults with MS (Linde, et al) • Developmentally early appearing patterns more common • Balance appears to be a factor affecting performance • Women in a weight loss program (Pope) • Those who lose weight demonstrate age appropriate patterns • Adults with TKR (Doyle, et al) • Early appearing patterns more common • Flexibility and Balance are factors
Studies of Righting • Children who are Healthy • BMI makes a difference
Other Tasks • Rising from Bed • Sarnacki – young adults • O’Neil-McCoy - teenagers • Ford-Smith – middle aged adults • Bodden, et al, - older adults • Sherwin – adults with back pain, • M. King, et al. – children • Allard – women through 1st ; 2nd and 3rd trimester of pregnancy
Other Tasks • Rolling Supine to Prone • Richter – young adults • Boucher - teenagers • Lewis – children • Richter et al. – middle aged adults • MacDonald - infants • Miller, et al – older adults
Other Tasks • Posture of Children while Using a Computer • Chase, et al • Novak, et al • Posture of Children while Horseback Riding • Belissary
Other Tasks • Scooting in Bed • Cohen, et al – young adults • Mount, et al – older adults
Paradigm Shift • Active Organism • Progression & Regression • Gains & Losses • Could factors other than the nervous system cause change? • Systems Theory • Different systems influence movements at different times during the life span • Dynamical Systems • Ecclesiastes 3:1-8 • To every thing there is a season...
Studies of Factors Affecting Righting Performance • Rising with Weighted Vest (Dehadrai) • 15% of body weight affects rising patterns • Rising with SAFOs (L. King) • Constraints to Ankle movement alter rising pattern • Rising with Bledsoe Boots (L. King) • Fixed plantar flexion affects rising pattern • Loss of toe break affects rising • Rising with Knee Cages (Brodovsky) • Constraints to knee movement alter rising pattern
Studies of Factors Affecting Righting Performance • Rising in aging active adults (VanSant, Haywood & Williams) • Health status • Rising in active and inactive young adults (Williams and Greene) • Activity level • Rising in active and inactive older adults (Leuhring) • Active adults more frequently demonstrate patterns more common in younger adults
Factors that Push Variability in Rising • Activity Level • Age • Balance ability • Body weight • Body dimensions • Body Topography • Intention (fast, slow, vary form, pretend) • Perceived Health Status • Restricted Range of Ankle motion • Restricted Range of Knee motion
Characteristics of the Individual • Age • Balance ability • Health Status • Activity Level • Body Weight • Body Dimensions • Body Topography
