1 PHYSICAL DISABILITIES

2 Physical Disabilities May Be A Result Of... Neuromuscular (Spina Bifida, Spinal Cord Injury) Neuromuscular (Spina Bifida, Spinal Cord Injury) Orthopaedic (Amputations) Orthopaedic (Amputations) Cardiovascular (Stroke) Cardiovascular (Stroke) Pulmonary disorders (COPD, Cystic Fibrosis) Pulmonary disorders (COPD, Cystic Fibrosis)

3 WE ARE GOING TO FOCUS ON....

4 Spina Bifida Dr. Amanda Faith Casey Department of Human Kinetics St. Francis Xavier University

5 What is Spina Bifida? What? Congenital defect of spinal column involves failure of vertebrae to completely enclose the spinal cord or it’s coverings (meninges). What? Congenital defect of spinal column involves failure of vertebrae to completely enclose the spinal cord or it’s coverings (meninges). When?: 4 th - 6 th week of pregnancy. When?: 4 th - 6 th week of pregnancy. Bifida: Latin word “cleft” or “split into two parts”. Bifida: Latin word “cleft” or “split into two parts”. How many? 11,000 children born each year (CDC, 2010). How many? 11,000 children born each year (CDC, 2010).

6 Important Considerations… Lack of fusion of the bone plates that form the spinal arch may affect any level of the vertebrae. Lack of fusion of the bone plates that form the spinal arch may affect any level of the vertebrae. Several vertebrae may be fused together (shorter back). Several vertebrae may be fused together (shorter back). Bony protrusion in the midline of the back. Bony protrusion in the midline of the back. Leg, bladder and bowel difficulty possible (Shin, 2010) Leg, bladder and bowel difficulty possible (Shin, 2010)

7 Diagnosis Of Spina Bifida Prenatal Tests 1. Alpha-fetoprotein (AFP) Test –Between 16 and 18 weeks –Blood sample taken from mother –High AFP reading linked to Spina Bifida 2. Ultrasounds - Spinal defects visible. 3. Folic acid - ↓ folic acid = ↑ risk of Spina Bifida -

9 Types of Spina Bifida Type 1: Spina Bifida Occulta Type 1: Spina Bifida Occulta Type 2: Spina Bifida Meningocele Type 2: Spina Bifida Meningocele Type 3: Spina Bifida Myelomeningocele Type 3: Spina Bifida Myelomeningocele

10 Occulta Mildest form. Mildest form. Affects any level of the spine. Affects any level of the spine. Signs (Williamson, 1987) Signs (Williamson, 1987) –A tuft of hair –Birthmarks –Dimple mark on the occulta Mainly in the lower part of the back. Mainly in the lower part of the back. Symptoms Symptoms –Back stiffness and pain –Fat pat over the occulta Skin covers spinal deformity. Skin covers spinal deformity. Does NOT cause paralysis or muscle weakness Does NOT cause paralysis or muscle weakness Associated with adult back problems. Associated with adult back problems.

11 Meningocele Meninges push through the hole in the vertebrae Meninges push through the hole in the vertebrae When Sac (meningocele) NOT covered by skin surgery becomes urgent. When Sac (meningocele) NOT covered by skin surgery becomes urgent. Hydrocephalus may occur. Hydrocephalus may occur. May have few/no symptoms or May have few/no symptoms or –Incomplete paralysis with urinary and bowel dysfunction. –A fluid filled sac protruding from the spinal cord.

12 Myelomeningocele Myelomeningocele Most severe. Most severe. Differs from meningocele in that the spinal cord is also pushed through the hole in the vertebrae. Differs from meningocele in that the spinal cord is also pushed through the hole in the vertebrae. Classified as defect of the neural tube. Classified as defect of the neural tube. Death 10% of infants. Death 10% of infants. Bowel/ bladder control problems. Bowel/ bladder control problems. ADHD or other learning disabilities. ADHD or other learning disabilities. Some paralysis (Tarby, 1991) Some paralysis (Tarby, 1991) Severity depends on where opening occurs on the back. Severity depends on where opening occurs on the back. –The higher the position = More severe paralysis % hydrocephalus 80-90% hydrocephalus (Shin, 2010).

13 Hydrocephalus... Cerebral spinal fluid (CSF) does not flow properly and builds up in the ventricles of the brain causing pressure. Cerebral spinal fluid (CSF) does not flow properly and builds up in the ventricles of the brain causing pressure. Surgically relieved by shunting procedure. Surgically relieved by shunting procedure. Shunts (tubes or catheters) sometimes become clogged and must be replaced. Shunts (tubes or catheters) sometimes become clogged and must be replaced. Symptoms of shunt problems: Symptoms of shunt problems: –Headaches -irritability –Vomiting -swelling –Seizures –Lethargy No activity restrictions except avoidance of trauma to the head. No activity restrictions except avoidance of trauma to the head. Only visible evidence of shunt is a small scar behind the ear. Only visible evidence of shunt is a small scar behind the ear.

14 Treatment: Pre Versus Post Natal Surgery???? Traditionally post natal surgery performed. Traditionally post natal surgery performed. Surgical repair of a spinal birth defect before birth may improve mobility and reduce risk of serious complications from MM. Surgical repair of a spinal birth defect before birth may improve mobility and reduce risk of serious complications from MM. New research: Infants who received prenatal surgery less likely to need follow-up procedure to divert or shunt, fluid away from the brain. New research: Infants who received prenatal surgery less likely to need follow-up procedure to divert or shunt, fluid away from the brain. Prenatal surgery resulted in significant improvements to both mental and motor functions. Prenatal surgery resulted in significant improvements to both mental and motor functions. Children in prenatal surgery twice as likely to be able to walk without orthotics or crutches (42%) as children who received postnatal surgery (21%). Children in prenatal surgery twice as likely to be able to walk without orthotics or crutches (42%) as children who received postnatal surgery (21%). Prenatal surgery more likely to cause preterm labour. Prenatal surgery more likely to cause preterm labour. See Adzick et al., 2011 See Adzick et al., 2011

15 Planning Physical Activity Initiate PA early to facilitate functional movement. Initiate PA early to facilitate functional movement. Need to ascertain movement potential. Need to ascertain movement potential. Exercise should involve wide-range of activities (Horvat, 2007). Exercise should involve wide-range of activities (Horvat, 2007). Flexibility exercise – To delay contractures. Flexibility exercise – To delay contractures. Resistance exercise – To increase functional strength Resistance exercise – To increase functional strength Aerobic training – To promote healthy lifestyle & aid weight management. Aerobic training – To promote healthy lifestyle & aid weight management. Aquatics may offset weakness in lower extremities. Aquatics may offset weakness in lower extremities. HR elevated 20-45mins (ACSM, 2010). HR elevated 20-45mins (ACSM, 2010). Teach gross motor skills to facilitate coordination. Teach gross motor skills to facilitate coordination. Triceps & shoulders important to train as aid in wheelchair transfers (O’Connell, 1992). Triceps & shoulders important to train as aid in wheelchair transfers (O’Connell, 1992). Latex Allergy Latex Allergy Possible weight gain added complication to reduced functional status (Dixon & Rekate, 1991). Possible weight gain added complication to reduced functional status (Dixon & Rekate, 1991). Complete fitness program = decreased obesity, stronger bones, better bowel function (Horvat, 2007) Complete fitness program = decreased obesity, stronger bones, better bowel function (Horvat, 2007)

17 Benefits of Physical Activity for Individuals w/ Spina Bifida ResearcherParticipantsPurposeResults Wright, C.M., Parker, L., Lamont, D., & Craft, W. (2001). 932 members of thousand families 1947 birth cohort. 412 attended for clinical examination. To determine whether being overweight in childhood increases adult obesity and risk of disease. BMI at age 9 was significantly correlated with BMI at age 50. Only children who were obese at 13 showed an increased risk of obesity as adults. Andrade,C-A., Kramer, J., Garber, M., & Longmuir, P. (1990). 16 children with SB born between 1976 and boys and 8 girls (10 community ambulators and 6 wheel chair users). Documented self-concept, cardiovascular endurance & isometric muscular strength of children with SB, and examine the changes during a 10 week exercise program. Improved self-concept, cardiovascular endurance, and isometric strength. An, J., & Goodwin, D.L. (2007). An, J., & Goodwin, D.L. (2007). Seven mothers of children with SB. Each of their children used wheelchairs as a mode of transportation. This study was examining the role mothers play in inclusive physical education for students with SB, and what their perspectives were on it. Analysis revealed three main themes: a) a good thing but… b) connection to sports & c) beyond the curriculum. Mita et al. (1993) 35 chidren with spina bifida and 129 children without a disability were a control group. To determine the percentage body fat of children with SB, using underwater weighing and skinfold thickness to assess their obesity. The percentage body fat of children with hydrocephalus was significantly greater than children without hydrocephalus. Skinfold error was not substantial compared to underwater weighing (Nagamine & Suzuki method). Groff, D., Lawerence, E., & Grivna, S. (2006) 11-year-old male who had cerebral palsy, was deaf, and cortical visual impairment. To increase the boys physical activity to prevent physical regression of his physical abilities while responding to a medical treatment. The aerobic endurance, muscular strength and gross motor skills of the boy were slightly improved. Rimmer, J.H., Connor-Kuntz, F., Winnick, J.P., & Short, F.X. (1997) 32 children and adolescents with spina bifida.(11 have thoracic lesions and 21 have lumbar lesions). Seventeen females and 15 males from years old. To determine the feasibility of the TAMT in a group of children and adolescents with SB++. That TAMT was accurate for assessing moderate activity for people with spina bifida.
