Question 1

I’m facing an amputation. What should I do first?

Accepted Answer

Contact our office for a presurgical consultation information packet at no charge. Call 844-583-6801.

Question 2

What kind of prosthesis will I get?

Accepted Answer

Gathering information about your level of physical fitness and health, the amputation level, the demands you place on the prosthesis and your future goals are just a few of the considerations that will help us to determine what type of prosthesis would be most appropriate for you.

Question 3

What’s the difference between a temporary and definitive prosthesis?

Accepted Answer

A temporary prosthesis is used for up to a year in situations where you are likely to experience volume loss/shrinkage resulting in a very loose fitting socket. A definitive prosthesis could last years due to minimal changes in your residual limb.

Question 4

How long does it take to get a prosthesis?

Accepted Answer

On average, it can take four to six weeks from the time you are evaluated to the time that you are fit with a prosthesis, depending upon what prosthesis you choose.

Question 5

Will my prosthetist teach me how to walk again?

Accepted Answer

The prosthetist’s goals are to ensure that the prostheses fit and function properly which usually involves some training. However, learning how to walk again and/or achieve functional goals while wearing the prosthesis is where physical therapy can be of great benefit.

Question 6

How often should I see my prosthetist?

Accepted Answer

See your prosthetist every six months or sooner if the prosthetic is not functioning or fitting properly, your activity level has changed, or if you have had a weight gain/loss.

Question 7

Do I need any other help in learning to wear a prosthesis?

Accepted Answer

A physical therapist can help you to wear and use your prosthesis while improving strength, balance and coordination. We can help you to find this health professional if you wish.

Question 8

What is a peer counselor?

Accepted Answer

This is an individual who has experienced limb loss and can provide personal insights to assist with questions you may have. They are a good source of information and we can recommend one for you upon request.

Question 9

Will I be able to do the things that I was doing before losing my leg?

Accepted Answer

Typically, after getting your strength back and learning to walk with a prosthesis, you should be able to return to your normal activities.

Question 10

Why is my prosthesis so heavy?

Accepted Answer

The anatomical amputated leg usually weighs more. The sense that the prosthetic device is heavy is more related to the need to adjust to wearing the device. Wearing the prosthesis loosely and generalized weakness can also create a perception that the device is heavy.

Question 11

Can I wear my prosthesis 24-hours per day?

Accepted Answer

Most prostheses are not meant to be worn around the clock. If you have difficulty in getting to the bathroom during the night without putting on your device, it may be helpful to keep a walker, wheelchair or other assistive equipment near your bed to help you safely reach the restroom.

Question 12

Will my prosthesis look like my real leg?

Accepted Answer

Yes. Foam can be used to cover the structural components and provide a more anatomical shape.

Question 13

Can I get my prosthesis wet?

Accepted Answer

Most prosthetic devices are not waterproof. Slight exposure such as walking briefly through the rain is usually fine, but they should not be worn while swimming or bathing unless specifically directed. If your device becomes wet, remove and dry it before putting it back on.

Question 14

Can I drive with my prosthesis?

Accepted Answer

Some devices can be worn while driving but others may interfere with your ability to operate the controls of the vehicle. Contact the DMV to see what is required for you to do so legally and safely.

Question 15

Can I wear my device through airport security?

Accepted Answer

Many prosthetics contain metal parts that will be recognized by scanners. We recommend talking with the security professional conducting the screening about your device and your needs. Do not remove your device if it risks injury or goes against medical advice.

Question 16

Why are prostheses so expensive?

Accepted Answer

Insurance companies establish the pricing for all prosthetic components through a Fee Schedule, which accounts for both the components and the practitioner’s time in fabricating, fitting, and adjusting them.

Question 17

Will my insurance cover the cost of a prosthesis?

Accepted Answer

Coverage depends on your specific health plan. Refer to your policy to see if prosthetic services are covered.

Question 18

What insurance do you accept?

Accepted Answer

Bio Dynamic Technologies accepts many insurances. Call us and we will research your coverage.

Question 19

Can I make payments if I do not have insurance or partial coverage?

Accepted Answer

Yes. We will work with you to find the best treatment plan for your budget.

Question 20

Can I use my workers’ comp or auto insurance?

Accepted Answer

Yes. We work with many different workers’ comp and auto/no fault insurance policies.

Question 21

Is there a warranty for my device?

Accepted Answer

All prosthetics we provide are covered by warranty, though the length of time varies with each device.

Question 22

Can my prosthesis be repaired?

Accepted Answer

Many custom-made devices can be repaired or refurbished depending on the exact nature of the problem.

Question 23

My doctor prescribed a custom or ready-to-fit brace for me. How do I get it and will my insurance cover that?

Accepted Answer

Our certified orthotists and/or orthotic fitter will review your doctor’s prescription. You may visit our offices in Manhattan, East Rutherford, NJ, or Greenwich, CT for fitting. Depending on your insurance plan, all or part of the cost may be covered. You are responsible for any uncovered amount.

Question 24

What are the benefits of wearing an osteoarthritis knee brace?

Accepted Answer

The benefits of wearing an osteoarthritis knee brace include reducing bone-on-bone friction, relieving long-term pain, and potentially postponing or eliminating the need for surgery. The brace also reduces reliance on medication and can be worn comfortably throughout the day. Its low profile allows it to be worn under clothing, such as slacks.

Question 25

What is osteoarthritis (OA)?

Accepted Answer

Osteoarthritis (OA) is the most common form of joint pain, affecting over 20 million Americans. It occurs when the cartilage at the end of bones wears away, causing the bones to rub together. This leads to pain, stiffness, and swelling in the affected joint, typically in the knees, hips, back, or feet.

Question 26

Who should use an OA knee brace?

Accepted Answer

An OA knee brace can help individuals with mild to severe knee OA. They are available in both off-the-shelf and custom-fit designs, making them suitable for any leg size.

Question 27

How does an OA knee brace work?

Accepted Answer

An OA knee brace works by applying gentle pressure on the sides of the knee, using 3-point leverage. This helps to reduce bone-on-bone friction and restore mobility, especially when cartilage degeneration causes the lower leg to bend inward or outward.

Question 28

Does an OA knee brace replace surgery?

Accepted Answer

An OA knee brace does not replace surgery but can help postpone it. While the brace won't repair the damaged joint, it can alleviate pain and delay the need for knee replacement, especially in mild to moderate cases.

Question 29

Does an OA knee brace replace physical therapy?

Accepted Answer

No, an OA knee brace does not replace physical therapy. In fact, it can make physical therapy more effective by reducing pain and improving the ability to exercise, helping you strengthen the muscles around your knee joint.

Question 30

Does an OA knee brace reduce the need for medication?

Accepted Answer

Yes, many patients who use an OA knee brace report a reduction in their reliance on pain and anti-inflammatory medications. This can be beneficial, especially since some medications have serious side effects. Always consult your doctor before altering your medication regimen.

Question 31

Can an OA knee brace replace costly drug injections?

Accepted Answer

Yes, in many cases, an OA knee brace can replace the need for expensive drug injections like corticosteroids or hyaluronic acid. Although these injections provide short-term relief, they can be costly, and their effectiveness varies. An OA knee brace may help extend the benefits of such treatments.

Question 32

What is Continuous Passive Motion (CPM) therapy?

Accepted Answer

CPM is a therapy prescribed after surgery or joint trauma to help avoid stiffness. It allows for a slow, controlled range of motion to promote healing and reduce discomfort in affected joints such as the knee, shoulder, elbow, or hand.

Question 33

Will my insurance cover CPM therapy?

Accepted Answer

Most insurance plans consider CPM therapy a medical necessity. We will assist in obtaining pre-authorization and confirm the extent of your coverage with your insurance carrier.

Question 34

What is cold therapy and how does it help after surgery or injury?

Accepted Answer

Cold therapy helps reduce inflammation, pain, swelling, and stiffness after surgery or injury. It can speed up recovery and decrease the need for narcotic pain medications, making it a safer alternative for managing post-surgical pain.

Question 35

What are the benefits of cold therapy?

Accepted Answer

Cold therapy offers several benefits, including decreased pain, reduced swelling and inflammation, and a decreased need for narcotic pain medications.

Question 36

What are the benefits of combined cold and active compression therapy?

Accepted Answer

Combined cold and active compression therapy provides better pain control, increases the likelihood of reducing narcotic usage, improves range of motion during post-op recovery, and contributes to better short-term clinical outcomes.

Question 37

Does insurance cover cold therapy systems?

Accepted Answer

Cold therapy systems, including cold and compression devices, are typically not covered by insurance. However, they are an investment in recovery and may reduce the need for other treatments.

Question 38

How long should I use cold therapy after surgery or injury?

Accepted Answer

Cold therapy should only be used as prescribed by your healthcare provider. Your provider will give specific instructions on frequency, duration, and the temperature settings to follow for your recovery.

Question 39

What are the common uses for cold therapy?

Accepted Answer

Cold therapy is commonly used after surgeries like ACL, MCL, or Meniscus repair, as well as for chronic conditions such as osteoarthritis. It is also useful in physical therapy and post-trauma recovery.

Question 40

What are the risks of cold therapy?

Accepted Answer

Cold therapy products can cause serious injury if not used properly. It is important to follow the instructions provided by your healthcare provider to avoid any potential risks.

Question 41

What is bone growth therapy and who needs it?

Accepted Answer

Bone growth therapy is prescribed for patients with healing complications, such as fractures or spinal fusions. It may also be recommended for individuals with risk factors that hinder bone healing, like smoking, diabetes, or obesity.

Question 42

How long will it take to heal with a bone growth therapy device?

Accepted Answer

The duration of bone growth therapy depends on the individual’s healing process, risk factors, and compliance with wearing the device. Most patients wear the device for three to nine months.

Question 43

Is there financial responsibility for patients using a bone growth stimulator?

Accepted Answer

Even if bone growth therapy is deemed medically necessary, some insurance plans may require patients to pay a portion of the cost, such as a deductible, co-payment, or co-insurance.
