What is a Spinal Cord Injury ?

spinal cord injury (SCI) is generally described as damage or trauma to the spinal cord that has resulted in lost and/or impaired function resulting in reduced mobility and/or feeling.

Common causes of damage to the spinal cord are trauma (car/motorcycle accident, gunshot, falls, sports injuries, etc.), or disease (Transverse Myelitis, Polio, Spina Bifida, Friedreich's Ataxia, spinal cord tumor, spinal stenosis, etc.). This damage to the spinal cord is known as a lesion, and the paralysis is known as quadriplegia if the injury is in the cervical (neck) region, or as paraplegia if the injury is in the thoraciclumbar or sacral region.

The spinal cord injury level is usually referred to alpha numerically, relating to the affected segment in the spinal cord, ie, C7, T10, L3 etc.

Below the conus medullaris (L1-L2), the spinal canal contains a mass of nerves referred to as the cauda equina or “horse-tail”. These spinal  nerves divide off the lower end of the spinal cord and contain the nerve roots from L1-5 and S1-5. Injury to these nerve roots are referred to as cauda equina syndrome.

It is possible for someone to suffer a broken neck,or a broken back without becoming paralysed. This occurs when there is a fracture or dislocation of the vertebrae, but the spinal cord has not been damaged.

Complete and Incomplete Spinal Cord Injuries

There are typically two types of lesions associated with a spinal cord injury, these are known as a complete spinal cord injury and an incomplete spinal cord injury. A complete type of injury means the person is completely paralysed below their injury. An incomplete injury, means only part of the spinal cord is damaged. A person with an incomplete injury may have sensation below their lesion but no movement, or visa versa. There are many types in incomplete spinal cord injuries, and no two are the same.

Such injuries are known as Brown Sequard SyndromeCentral Cord Syndrome,Anterior Cord Syndrome and Posterior Cord Syndrome.

Spinal Cord Injury Rehabilitation

Rehabilitation for individuals with a spinal cord injury combines physical therapies with skill-building activities. These activities will usually take place at a specialist center such as a spinal cord injury rehabilitation center or spinal injury center. A rehabilitation team will usually oversee activities and include a doctor specialising in spinal injuries, social workers, physical and occupational therapists, sports educators, rehabilitation nurses, rehabilitation psychologists, vocational counselors and nutritionists.

Generally, a paraplegic will be in hospital for around 5 months, where as a quadriplegic can be in hospital for around 6 – 8 months. Both paraplegics and quadriplegics should have some kind of rehabilitation and physiotherapy before they are discharged from hospital, to help maximise their potential, or help them get used to life in a wheelchair, and to help teach techniques which make everyday life easier.

Disabled sports, and wheelchair based sports can be an excellent way to build stamina, and help in rehabilitation by giving confidence and better social skills. The ultimate reward for many disabled sportsmen and women, is to win at the paralympic games, which will be coming to London in 2012.

Spinal Cord Injury Cure and Treatment

A cure for long term paralysis is still some years in the future, but clinical trials are taking place with olfactory ensheathing glial (OEG) cells and embryonic stem cell based therapy.

Quadraplegic, Tetraplegic, Paraplegic and it's Definition

Quadraplegic is derived from two separate words from two different languages, Latin and Greek. The word “Quadra”, meaning “four” which is derived from Latin, relates to the number of limbs. “Plegic”, is derived from the Greek word “Plegia”, meaning paralysis.

Put the two together, and you have “Quadraplegia”.

“Tetra” is derived from the Greek word for “Four”. “Para” is derived from the Greek word for “two” Hence: Tetraplegic and Paraplegic.

In Europe, the term for 4 limb paralysis has always been tetraplegia. The Europeans would never dream of combining a Latin and Greek root in one word.

In 1991, when the American Spinal Cord Injury Classification system was being revised, the definition of names was discussed. The British are more aware of Greek versus Latin names. Since Plegia is a Greek word and quadri is Latin, the term quadriplegia mixes language sources. Upon review of the literature, it was recommended that the term tetraplegia be used by the American Spinal Cord Association so that there are not two different words in English referring to the same thing.

Which power stand up wheelchair is better?

Which Karman wheelchair is right for me?
Manual propel power stand is an option for those whom want to be able to still stay active in propelling themselves. The power stand option really acts as an assistive device and helps the person stand up. Your PT should work with your ATP or medical professions to see if the added extra power mobility and power ELR or elevated leg rest and tilt functions are a medical necessity to you. Of course if the budget allows, these options can always be helpful to someone whom needs extra care and assistance. At Karman, we have over 100 models for manual wheelchairs to choose from.  In general, if you can propel yourself in a wheelchair, you will want the lightest most comfortable wheelchair available.  Learn more about all the categories available and then choose by product weight and budget.  Here are some categories and information for your review:

Transport Wheelchair

Transport wheelchairs are the perfect choice for transporting someone to and from the places you would love to travel with.  A transport wheelchair is generally narrower and lighter than a standard wheelchair, making it a good choice for tight obstacles and narrow entryways.  There are differences between our high end Crash Tested S-ERGO series transport wheelchairs and also economy grade products.  Some great choices include our ERGO LITE and S-115TP.  We also have a wheelchair made for traveling, TV-10B.

Standard Weight Wheelchair

Most standard weight wheelchairs starts at 34 pounds, a standard weight wheelchair is a great option when you need a wheelchair that will be not be frequently used; generally 3 hours or less per day and with infrequent transfers.  Our full selection is available from the most basic models with fixed legrests and armrests to wheelchairs that have optional elevating legrests and removable armrests.  There are also models with optional accessories to enhance your wheelchairFoam cushions and/or Gel Cushions provide for additional comfort.

Lightweight Wheelchair

With weights ranging from 25-34 pounds, our lightweight wheelchair is a great choice when you need a wheelchair that is more frequently used, when you need special options, or when you have your heart set on a specific frame and/or upholstery color combination.  This category covers it all, with lightweight wheelchairs at competitive prices.  These wheelchairs offer more options and we typically recommend that a comparison be done with the next step up category which is our ultralight weight wheelchairs where the ultimate mobility equipment and features are at its very best.

Ultralightweight Wheelchair

This is the category of wheelchairs where the best of the best resides.  With wheelchair weights as low as 14.5 pounds and available in both S-ERGO and simply super lightweight models, an ultralight weight wheelchair is for the full-time user who demands performance and for those who want the lightest wheelchair possible for ease of self propel and transport.  In this category, you will have a number of features never found on any competitors like standardize crash tests on S-ERGO models and tons of options and accessories not offered on other base categories in wheelchair options.

Active Wheelchair

Our ERGO ATX offers the finest in a combination of wheelchair manufacturing disciplines. These criterias includes but is not limited to maximum adjustability, rigidness, ultra lightweight, comfort, foldability, style and outstanding performance.  Our Ultralightweight wheelchair category takes zero compromise with our R&D department pushing the latest manufacturing techniques and capabilities and transferring them to you right on the streets.

Tilt / Recline Wheelchair

A reclining back or otherwise known as a "high back" wheelchair is a great option for those who spend the majority of their time in a wheelchair as it offers more positions to recline.  And a tilt wheelchair offers alternative positioning and pressure relief for those who are requiring further pressure relief for prolonged usage of a wheelchair.  Both our categories have effectively reduced weight of traditional competitors so keep in mind when shopping on price.
