Orthopedic Impairments

Definition: Orthopedic impairment occurs when an orthopedic disability adversely affects a child’s educational performance. The impairments include the effects of congenital anomalies, effects of disease, and other causes. Orthopedic impairments can be classified into three different categories; neuromotor impairments, degenerative diseases, and musculoskeletal disorders. Neuromotor impairments are caused by damage to the brain, spinal cord, or nervous system. It sends impulses through the body that cause complex problems in multiple body systems. The two most common impairments are spina bifida and cerebral palsy. Degenerative diseases effect motor development. The most common disease is muscular dystrophy. This is caused by progressive muscle weakness from muscle fibers degenerating. Musculoskeletal disorders compose of many different impairments that occur in different levels of physical limitations. These may include the loss of limbs and juvenile rheumatoid arthritis. According to the US Department of Education, approximately 1.1% of children receiving special education services where because of orthopedic impairments. Orthopedic impairments may be acquired at or before birth, inherited, or be caused by accidents.

Implications: Teaching students with orthopedic impairments can be very challenging. I plan to teach first, second, or third grade. At this age, the students may still be trying to become accustomed to their impairment. For the student, I would first meet with them and their parents to find what they may have difficulty with. Depending on what impairment the student may have, different adaptations will need to occur. First, special seating arrangements may need to be assigned due to assistive devices or different body contractures. For impairments of the upper extremities, students may need lectures or instructions tape recorded. Desks, blackboards, sinks, and workstations may need to be lower for wheelchairs. Students may need extra time for tests or timed quizzes due to slower writing time. For breaks and classroom changes, the student may need extra time to get from one area to the next.

Specific Technology:

Tape Recorder: To record lectures and instructions for students that may write slower

Computer: Can be used for students that may need extra time for writing or research

Walker: Can be used to help students walk or balance

Cane: Can be used with balance or instability issues

Crutches: Can be used for keeping weight off of limbs or for missing limbs

Splints/Braces: Cab be used to stabilize joints due to weak muscles

Traumatic Brain Injury

Definition: Traumatic brain injury is damage to the brain caused by some type of trauma. The trauma can be from a blow, strike, jolt, lack of oxygen, tumors, infections, stroke, or chemical exposure. These different traumas cause different changes to the brain. The brain can bruise, which happens when the brain is smashed into the skull causing blood vessels to break causing a bleed. The brain can also tear. This can cause tears in the “wires” of the brain. The brain can also become swollen. The increase in size will damage structures of the brain when it becomes too large for the skull. There are also open head injuries and closed head injuries. The open head injury occurs when the skull actually breaks open. The closed head injury occurs when there is damage to the brain, but the skull is intact. A traumatic brain injury can range in severity from mild to severe. A mild traumatic brain injury may cause little to no problems including headaches, temporary memory loss, or loss of balance. A severe traumatic brain injury can cause many problems such as language difficulties, sleep disorders, impaired senses and even severe as death. There are approximately 5.3 million Americans that require long-term or lifelong help from traumatic brain injury. There are multiple different scans that can help diagnose a traumatic brain injury. These may include CAT scan, MRI scan, SPECT scan or PET scan. A doctor may also include evaluations from a neuropsychologist, speech therapist, physical therapist, or occupational therapist. The first step of treatment is medical care including monitoring, surgery, stabilization, or even resuscitation. Once the main cause is stabilized and such, the rehabilitation process begins. This can last for only a short time or can be lifelong. The rehabilitation team can consist of all of the personnel that assisted with diagnosis.

Implications: How I approach a student with traumatic brain injury will greatly depend on the severity of the injury. I plan to teach in the general classrooms of first, second, or third grade. In the cases of severe traumatic brain injury, I will more than likely have little to no interaction with them. The para will have more of the interaction. In milder cases, I will have to make adjustments. The first step would be to meet with the parents, faculty, and student to get an IEP for them. The next step would be for me to find that students best style of learning. Because traumatic brain injuries can cause such a wide variety of problems, I would take their issues step by step. First if they have a speech or language problem, I would work with the therapist. I could use flashcards, posters, or computer programs to help them. If my student had memory or sensory deficits, I would write my instructions, express my instructions, and do whatever necessary to make sure they know what they are supposed to do and how they are supposed to do it.

Specific Technology:

Computer: Students may use the computers to use software for memory, for speech or language difficulties, or just to research.

CAT Scan: Computerized Axial Tomography used to diagnose TBI

MRI Scan: Magnetic Resonance Imaging used to diagnose TBI

SPECT Scan: Single Photon Emission Computed Tomography used to diagnose TBI

PET Scan: Positron Emission Tomography used to diagnose TBI

Gifted and Talented

Definition: A gifted or talented student is one that has high achievement capability in intellectuality, creativity, or leadership. They may be exceptional in other specific areas, but need more services than provided in the regular classroom to reach their full potential. A gifted student posses many different qualities such as having a good memory, quick learner, motivated, involved in many things, independent, and self-motivated. Indicators for giftedness or talented may start at a very young age. Therefore, a parent may be able to watch for these and begin challenging right away. Some of these might include walking and talking early, long attention spans, or being very intuitive. Students that are gifted need to be accepted as individuals and not placed into a group. They may need help dealing with frustration and need extra emotional support and acceptance. Gifted and talented students have many great qualities, but do have some challenges. They are considerably hard on themselves and others, impatient, strong-willed, and be more prone to depression and being “bossy.” For this reason, gifted students are just like any other child and need help with emotional support. They may need extra help making friends or dealing with things such as life changes and trauma.


Implications: I would like to teach first, second, or third grade. At this age, I feel I would need to be more involved with assessing whether a child is gifted or not. Once we give a student the term “gifted,” I would get the student an IEP. Of course, this student would get as much inclusion time as possible. This would not cause much problems at all. However, I would need to make sure that this student is challenged. By doing this, I would have to give them harder assignments, different spelling words, and more difficult projects. It would be very important for me to challenge all of my students, but I would need to make each student, whether challenged or gifted, work at their full potential. I would still incorporate different games and activities into the lesson. These students are like any child and may get bored or burnt out on school.

Specific Technology:

PowerPoint, Excel, Word, Access: These different software can help any student gain more knowledge in technology, math skills, research skills, and social skills.

SMART Board: This interactive board is a great way to challenge any student by interacting them with the material.

Computers/Laptops: Can be used to research, write papers, create presentations, ect.

DVD/Videos: A great way to show students a new concept or use as a field trip.

Deaf Blindness

Definition: Deaf-blindness is a condition in which an individual experiences difficulty in both hearing and vision. They do not have to have a total inability to hear or see. According to IDEA, it can cause severe communication, developmental, and educational problems. This cannot be accommodated by special education programs for children that are just deaf or just blind. A person that is deaf-blind, their world is significantly more narrow than a person with full vision and hearing. A person with deaf-blindness must rely on touching and feeling to experience the world. There are many different terms used to describe deaf-blindness; dual sensory impairment, combined vision and hearing loss, dual sensory loss, and dual sensory disability. There are many different challenges for a deaf-blind individual. They must rely on another individual at times, learn not only to communicate, but different methods, learn to navigate, find new methods of socializing and living, and degrading attitudes from other people. Deaf-blindness is caused by many different things. It can have hereditary/chromosomal causes such as Usher, Charge, or Down syndrome. Premature birth, prenatal or congenital complications, or meningitis could also cause deaf-blindness.

Implications: I plan on teaching somewhere in the lower grades. I would prefer first, second, or third grade. At such a young age, this condition may be a bit more difficult. They would probably just be figuring out some things that we take for granted. I think that this condition would be very difficult to incorporate in the regular classroom. I do think inclusion is very important. However, if I cannot allow myself enough time to help this child, that would not be fair. I would first do all the research I could on how best to educate him/her. Then I would make sure we got an IEP for them and began to do all the necessary steps including getting the technology and related services. It would be hard, but I would have to try to put myself in his/her place to educate them.

Specific Technology:

TTD: device that is used to communicate over the phone; the modem converts digital data from the computer into audio tones. They are then transferred through the phone line
TTY: a term used interchangeable with TTD
FSTTY: device similar to TTD and TTY, but the information is turned into Braille

Spina Bifida

Definition: Spina bifida (“split spine”) is a neural tube defect that is caused by incomplete development of the brain or spinal cord. Spina bifida is caused by the spine not fully closing in the first month of pregnancy. This can sometimes create an open lesion that has caused damaged nerves or spinal cord. This hole can be repaired but nerve damage is permanent so paralysis may occur. This is the most common birth defect that causes permanent disability. One out of every 1,000 births is affected by spina bifida. There are three types of spina bifida; occulta, meningocele, and myelomeningocele. Occulta is sometimes called hidden spina bifida because there is no opening in the back and the spinal cord and nerves are intact. The problem occurs because there may be a defect or opening in the vertebra. Sometimes this may not cause any problems at all. They may never even know they have spina bifida unless an x-ray is taken. However, some people experience bowel problems, back and leg problems, or brain deficits. Meningocele is the rarest type of spina bifida. It is caused by the bones not closing around the spinal cord. This causes the meninges to push through creating a sac filled with fluid. The spinal cord and nerves are rarely affected and this can usually be cured by surgery. Myelomeningocele is the most common and most severe type of spina bifida. In this type, a part of the spinal cord actually protrudes through the back. The type of neurological problems depends on the location of protrusion. It may be only small bowel problems up to total paralysis of both legs. The most common cause of spina bifida is a deficiency of folic acid during pregnancy. Some research has shown that genetics may play a part. The only treatment for spina bifida is surgery and it is never fully cured. Some problems that may also occur with spina bifida are hydrocephalus, Chiari II malformation, tethered spinal cord, urinary tract disorders, latex allergies, learning disabilities, obesity, digestive tract disorders, and psychological and sexual issues.

Implications: Teaching a student with spina bifida may require absolutely no changes. If they experience no problems as with occulta, they will require no special assistance. However, if they have medical problems such as paralysis or bowel problems, I will discuss with the family and a health professional as to what I need to watch for and how to care for my student throughout the day. As for the rest of the class, I would ask the parents if they would like to come in and discuss spina bifida with them. I feel that if the students understand it more, they will be more likely to accept the differences. If the student experiences neurological deficits, I would deal with them as they came along. My opinion is that a child should be included in the regular classroom as much as possible. If this begins to cause problems for them, I would send them to a resource room. However, in my regular classroom, I would try to have a paraprofessional to assist my student. I would work with my student to see what they have problems with and adapt my lesson plans for their benefit. If the spina bifida caused a learning disability, I would treat them as if they were no different from any other student with a learning disability. I would adapt to their deficits and gain information on how to better educate them.

Specific Technology:

Surgical shunt: A valve inserted to make cerebrospinal fluid go into the bloodstream instead of the brain

CIC: (clean intermittent catheterization) method used for problems with bladder and urinary incontinence

Assistive Technology: wheelchairs, braces, crutches, ect.

Myopia

Definition: Myopia is a condition that allows someone to see objects that are close clearly, but objects that are far are blurry. They may not have any trouble reading road signs or seeing a blackboard, but activities such as reading and sewing can be difficult. Myopia is caused by the eyeball being too long or the cornea is too curved. This causes the light entering the eye to focus correctly. The light focuses in front of the retina, rather than right on the surface. Symptoms can include squinting, fatigued from driving or such, headaches, eye strain, or blurry vision. Myopia is usually passed down from generations and gets worse with age. It can be caused by visual strain from things such as reading or using the computer. Myopia can be caused from someone having diabetes or from the beginning of a cataract. Myopia can be treated by contacts, eye glasses, laser surgery, or orthokeratology. Orthokeratology is the use of rigid contacts to reshape the cornea.

Implications: If I had a student that had myopia and wasn’t diagnosed, I would do everything I could to get it diagnosed and corrected. Once that happened, I would meet with that student and their parents to see what works best and how the student is affected. Because textbooks and paper assignments would not cause any problems, that would not be my focus. My focus would be put on the use of computers and distance things such as blackboards or overhead projectors. I would limit the on screen computer use because this can actually cause myopia and could actually make it worse. For activities that I may be writing on the board or using an overhead projector, I would make sure to write it up before hand to hand to this student. They should not miss out of any activities because of myopia.

Specific Technology:

Phoropter: instrument used to measure how your eyes focus light
Retinoscope: hand held instrument used to place light in your eye
Orthokeratology: use of rigid contacts to shape the cornea
PRK: removes piece of cornea to shape the cornea
LASIK: removes inner layers of cornea to shape it

Otitis Media

Definition: Otitis Media is the inflammation or infection of the middle ear. This can be caused from a cold, sore throat, or other respiratory problems that spread to the ear. These can be either a bacterial or viral infection. The Eustachian tubes connect the middle ear cavity to the outside and acts as a pressure equalizer. They also drain any fluid and mucus out of the middle ear cavity. When the infection moves to the Eustachian tubes, they become inflamed and the fluid and mucus becomes trapped. The four most common causes are allergy, infection, blockage of Eustachian tubes, and nutritional deficiency. There are two types of otitis media; acute and chronic. Acute usually occurs suddenly and only lasts for a short while. Chronic otitis media is a persistent infection and lasts for a minimum of a month. Children are at a higher risk of getting otitis media because their Eustachian tubes are shorter and more horizontal. At least two-thirds of all children experience at least one infection before the age of two. Because it occurs usually in younger children, it may be hard to recognize symptoms. These may include loss of hearing, loss of balance, pulling at ears, fever, or fluid drainage. To treat otitis media, there are several options. The most common is to treat the infection with antibiotics. If the infections occur over and over, tubes may be placed in the Eustachian tubes to keep them open. If the conditions worsen, surgery may become an option. These may include myringotomy, adenoidectomy, or tonsillectomy.

Implications: Because most cases of otitis media are temporary and not too severe, most teaching techniques may not need any change. However, if there is a case of chronic, there are several things I would do. First off, I would have a meeting with the child and his/her parent(s). I would speak to them about how they communicate and such. If the child knew or wanted to learn sign language, I would help him/her and learn it myself. I would also concentrate on speaking slower so that if they could read lips, it would make it easier. The next step would be to get an IEP. This student may need extra help including some of the following technologies or certain people. I would use many different visual aids. This would not only help them understand, but I believe it would be helpful for the entire class.

Specific Technology:

Hearing Aids: May be needed for individuals that can hear somewhat but needs it to be louder

Cochlear Implants: This device is surgically placed under the skin behind the ear to stimulate the auditory nerve.

TDD: (telecommunication device for the deaf) This could be used on a telephone line for people to use text to communicate over the telephone.

Telephone Ring Signalers: This device plugs into your phone directly and causes a lamp to flash when your phone rings.

Door Signalers: This unit requires wiring, but also flashes a lamp when someone rings your doorbell.
