Agendas for O&P professional development in India

2015-05-27T08:18:00.001-07:00

Hello everybody,

Since you have all joined the group in Whatsapp named "O&P Doctors", I would like to present three agendas for the forthcoming meeting on 30th May 2015. As suggested by our past ISPO chairman, Dr. Mehta Sir, on behalf of him the agendas are as followed. Here I would like to add the points suggested by Dr. Rajiv Verma Sir & Dr. Vinod Bhanti Sir.

1. Prefixing "Dr." before our name, any graduate/post graduate O&P running clinical practice or working for NGO or MNCs or government sectors should have the legal authority to use so. Gone are the days when O&P worked under the referrals of Doctors, now O&P is gradually becoming an independent profession. Here we are not going to prescribe drugs to our patients, rather the form of medicine that we deal with "Orthosis or Prosthesis". Members please dont be skeptical by comparing our profession with the failure of PT to do so.

2. Only an RCI registered O&P would be the licensed professional to deal with purchase and sale of OTS items, none others, same way drugs are only sold by an licensed Pharamcist. I, during my initial days struggled hard but got this big pot hole in our judiciary system; Leading OTS manufacturers like Vissco, United Medicare, Tynor, Dyna etc are pushing their product i.e. spinal brace, knee cap etc. with a tag mark "this item would be used by a disable person so tax exempted", whereas we are the only professional who can write the same none others are legally eligible. In our judiciary system, non VATed items can be sold by anybody without an original bill, so orthopedicians and physios are using this opportunity for black money generation. Our professionals who are practicing individually must have Tax Identification Number (TIN), in order to fight with them.

3. Our fellow practitioners working in any Government organization should have their own identity; from appropriate designations to free private practice (same as many of our orthopedic colleagues are doing in all NIs and state run hospitals). We have been fighting for salaries lets try a new way, ultimately dignity matters.

Apart from these agendas, as per suggestions by many yesteryear practitioners who were the founding member of OPSI; reviving the lost glory of OPSI by re-elcting the last EC of OPSI.

Dr. Rajiv Verma Sir have included:

- To stop e-marketing of OTS products and others associated with us.
- To appoint only P&O as chairman of RCI, P&O expert committee and 60-70% reservation for P&Os as it's committee members. (this point was a talk of town a few days before questioned by Dr. Thakur Sir and Dr. A. N. Nanda Sir).

Nike and Össur Collaborate on Breakthrough Running Sole for World Record Holder Sarah Reinertsen

2012-03-06T08:53:00.000-08:00

Nike is introducing a new sole utilizing state-of-the art design methods and technologies to create a lightweight, durable composite sole that can easily be used with Össur's Flex-Run prosthetic blade for amputee athletes.

Not all competitive athletes have the privilege of competing without obstacles, so Nike has designed the new Nike Sole in conjunction with amputee triathlete and World Record Holder Sarah Reinertsen and Össur, a leader in the orthopedics industry known for their advanced prosthetic innovations.

"The Sarah Sole project is a special one for Nike," said Tobie Hatfield, Nike Innovation Director. "The Nike Sole is a shining example of our passion and commitment to serve athletes and provide them the solutions they need to achieve their goals - we're always listening to the voice of every athlete."

The Nike Sole features an integrated layered sole including an outsole, midsole and thermal plastic urethane called Aeroply, made of recycled Nike Air Bag units, serving as moderator between Nike Sole and the Össur Flex-Run's carbon fiber blade. Nine nylon plastic tabs serve as fingers that wrap snugly around the Flex-Run carbon fiber blade for secure lock down and easy on-off. A stretch rubber leash with tactile grip tab for easy placement over medallion fastener provides additional security.

"The Össur Flex-Run enables amputees of all abilities to achieve their athletic goals," said Jon Sigurdsson, Össur's president and CEO. "This exciting collaboration has leveraged Össur's unmatched research and development in running prosthetics with Nike's first-class technologies, resulting in a product unlike any other."

The first Nike prototype sole used by Reinertsen was made from a Nike Free 5.0 Trail outsole, which was adhered to a plastic-based sleeve that would slide onto the blade. Tobie Hatfield, Nike's Innovation Director, worked closely with Reinertsen to tweak the next round of prototypes based on her feedback wear testing the sole unit.

Reinertsen, who faced the constant challenge of an unstable and unpredictable footwear solution, was born with proximal femoral focal deficiency. She had a bone-growth disorder which eventually led to her becoming an above-the-knee amputee at seven years old. Following the amputation she began to run track and broke the 100-meter world record for female above-the-knee amputees at the age of 13.

Like most competitive amputee athletes, Reinertsen competes today in marathons and triathlons using an Össur Flex-Run prosthetic carbon fiber blade and Nike Sole. In 2006, she began working with Hatfield and the Nike Innovation Kitchen on a solution for her prosthetic outsole needs.

Previously, Reinertsen would use the outsole of a traditional running shoe as her prosthetic "shoe." With limited innovations with prosthetic soles, this cobbling approach to creating solutions using regular running footwear had become the norm. The new Flex-Run with Nike Sole provides a reliable advantage and is now available through prosthetists' offices globally.

Reinertsen's career success includes seven marathons (NYC 1997, 1998; LA 1998, 1999; Millennium New Zealand 2000; London 2002; and Boston 2004) and she was the first female above the knee amputee to complete the Ironman(R) World Championship in Hawaii in 2005. She's hungry for more success.

CMT (Charcot–Marie–Tooth disease)

2012-01-03T23:34:00.000-08:00

Charcot-Marie-Tooth disease (CMT) is one of the most common inherited neurological disorders, affecting approximately 1 in 2,500 people in the United States. The disease is named for the three physicians who first identified it in 1886 - Jean-Martin Charcot and Pierre Marie in Paris, France, and Howard Henry Tooth in Cambridge, England. CMT, also known as hereditary motor and sensory neuropathy (HMSN) or peroneal muscular atrophy, comprises a group of disorders that affect peripheral nerves. Currently incurable, this disease is one of the most common inherited neurological disorders, and was considered a type of Muscular Dystrophy for years.

Cause:

Charcot–Marie–Tooth disease is caused by mutations that cause defects in neuronal proteins. Nerve signals are conducted by an axon with a myelin sheath wrapped around it. Most mutations in CMT affect the myelin sheath. Some affect the axon.

Types:

CMT can be categorized first into major clinical categories, and then into subtypes according to those mutations. Type 1 primarily affects the myelin sheath, and is either dominant, recessive or X-linked. Type 2 primarily affects the axon, and is either dominant or recessive. Other types are mixed.

Signs & Symptoms:

-Begin in late childhood or early adulthood

-Both motor and sensory nerves involvemen

-Neuropathic pain

-Mild Tremor

Deformity:

-Gross deformity like foot drop, scoliosis, hammer toe.

-Difficulty with carrying out fine motor skills (the coordination of small movements usually in the fingers, hands, wrists, feet, and tongue).

-The lower legs may take on an "inverted champagne bottle" appearance due to the loss of muscle bulk.

-Breathing can be affected in some; so can hearing, vision, as well as the neck and shoulder muscles.

Diagnosis:

-The diagnosis of CMT begins with a standard medical history, family history, and neurological examination.

-This testing consists of two parts: nerve conduction studies and electromyography (EMG).

Management:

There is no cure for CMT, but physical therapy, occupational therapy and even orthopedic surgery can help individuals cope with the disabling symptoms of the disease. In addition, pain-killing drugs can be prescribed for individuals who have severe pain.

Orthotic management:

-Gait abnormalities can be corrected by the use of either articulated or unarticulated AFOs which helps to control foot drop and ankle instability and often provide a better sense of balance for patients.

-Appropriate footwear is also very important for people with CMT, but they often have difficulty finding well-fitting shoes because of their high arched feet and hammer toes.

Case Study I

2012-01-02T00:34:00.000-08:00

Pt. Name: Aniket Kotak
Age: 10 years
Address: Belda, Mednipore, WB
Deformity: Right Mild Calcaneus Valgus, TA spasticity
Cause: Mild cerebral cortex dysfuntion
Gait: Steppage gait with toe dragging

Management: A regular PT can show some effectiveness but it may take months, hence a Carbon fibre laminated Dynamic AFO with Otto Bock ankle dorsiflexion assist joint was intervened to stretch the TA and maintain normal gait cycle without any deviation.

Result: Pt. is called for a follow-up after three months

Doubt: Can the stimulus, to the TA, by the orthotic joint add in correcting the deformity and reduction of the tone??

ABOUT THE BOOK WITH A FEW SCREEN SHOTS

2009-12-30T07:24:00.000-08:00

OBJECTIVES:

The main objective of this book is to uplift the knowledge and standard of Indian P&O students and to bring them as par with their foreign counterparts. This book is specially tailored for Indian P&O industry with accordance to their need and to upgrade their level of education. The level of prosthetics and orthotics education has risen along with the technical sophistication of the materials, methods and use of components. Now the time has come when all should join hands and bring back the glory which the Indians were once enjoying during the Vedic period of being highly scientifically sound among all others in the whole world. The main problem in India for P&O professionals are that there is no such streams that deal with the thing that we deal with i.e. let’s consider the CAD/CAM part that we have in our course curriculum, we need P&O components to be taught rather designing mechanical parts of any automobiles or machines, this is because we have to depend on normal mechanical engineers who are least consent what is needed for us hence, we suffer. This can be eradicated if we tie up with those mechanical engineers and share our ideas as in designing any mechanical parts of any prosthetics and orthotics components which is exactly done in this book.

In brief the features of this book are:

-This book is 1^st of its kind that is specially meant for any P&O student as well as the vast Indian P&O industry.

-This book is prepared strictly with accordance to the RCI syllabus and standard.

-This book is simple in language and highly illustrative.

-This book can be a handy guide for any computer related problems.

BIONIC ARM MECHANISM

2008-10-10T23:36:00.000-07:00

This bionic arm can do things like picking up fragile items such as a glass, just by the wearer just thinking about it. The arm is connected directly to the wearer, Jesse Sullivan's brain, so he's able to use it like any other appendage. The device weighs 12 pounds, and at this rate, I don't think it will be long to see a 'million dollar man' make headlines.
Electrodes intercept the limb's residual nerve firings and feed them to a computer embedded in the forearm, which then commands six motors to move the device's shoulder, elbow and hand in unison. Thanks to hand sensors, the wearer can even gauge pressure and fine-tune his grip.
