Cochlear implant is a medical device that provides direct electrical stimulation to the hearing nerve in the inner ear. Children and adults with a severe hearing lossmay be helped with cochlear implants. A cochlear implant is a prosthetic substitute directly stimulating the cochlea and it does not cure deafness or hearing impairment.
A cochlear implant completely by-passes the normal hearing mechanism and stimulates the auditory nerve directly by means of an internally implanted electrode assembly. The implant consists of an external portion that located behind the ear and an interior portion which is surgically implanted under the skin. An implant has a microphone, a speech processor, a transmitter and an electrode array. The sound from the environment is picked by microphone and transmitter and receiver/stimulator sends them to speech processor to convert them into electric impulses.
The speech processor placed with the microphone behind the ear, or it is a small box-like unit worn in a chest pocket. The speech processor digitizes the sound signals and sends them to a transmitter just behind the ear. The electrode array collects the impulses from the stimulator and sends those to different regions of the auditory nerve. The electrodes stimulate the fibers of the auditory nerve, and sound sensations are perceived.
A cochlear implant is very different from a hearing aid. Hearing aids amplify sounds so that they can be detected by damaged ears. Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve. Hearing via a cochlear implant is different from normal hearing and takes time to adjust. However, it enables many people to understand other sounds in the environment, recognize warning signals, , and understand speech in person or over the telephone.
The benefits from a cochlear implant depend on many factors, such as the age of the patient when he or she receives the implant, the hearing loss present pre or post patient developed language skills and finally the motivation of the patient and family support
Once a person is referred for cochlear implant, more testing is done which includes audio logic testing, psychological testing, medical examination, and tests performed by the surgeon. It is done to ensure that the candidate will benefit from a cochlear implant and will have the motivation to participate in the process. Once the decision is made to go ahead, the surgery is done. Sometimes it involves an overnight stay in the clinic, and sometimes it is done on an outpatient basis. Six weeks post-surgery, patient is fitted with the external microphone and speech processor and implant is activated and programmed.
The best candidates are those having severe hearing loss in both ears, limited benefit from hearing aids, medical condition that makes surgery risky. Children can be considered for cochlear implants if they have the similar conditions as adults and in addition have support from their educational institutions to development of auditory skills.
One month, the injury is still healing, two months, just a little bit longer, three months? Well, you, believe it or not, it has probably become a chronic pain and is affecting every aspect of your life. Chronic pain may be a novel notion to accept but is now understood to be a disease and generally defined as pain persisting for longer than 12 weeks. Pain management in such cases is traditionally treated through prescription drugs, the other option being amputation.104968
This is a major cause of patients having qualms about these pills and a need for an alternative. In response to this, doctors have a new tool to help decrease the perception of pain which is a small implant placed in the back to help patients shake off the pain. This small device that could bring you back to your feet is the spinal cord stimulator.
What is spinal cord stimulation?
Theoretically, the spinal cord stimulation is a type of neurostimulation which produces an effect that interferes with the brain’s ability to interpret the signal as pain by using electrical pulses. The brain, instead, experiences it as a pleasant numbing sensation. The implant is placed which takes place in two parts i.e. placing the lead device in the spine and placing the pulse generator in abdomen or buttock.
For test stimulation, the several stimulation settings are tried so that the pulse generator can be programmed using these settings. The procedure typically takes 1-2 hours and post-procedure, patients are given a handy device to control the simulations which they are to use in their day-to-day lives.
It has been observed to reduce the pain by at least 50%. However, this too has its limitations. Typical candidates are people with chronic back and limb pain who may have a failed back or disc procedure. The most common risks associated are device-related, example, unintended movement of the leads. Serious effects include hemorrhage in the epidural space or injury to a spinal cord leading to neural damage, but these are highly uncommon.
Quick facts about it
As it is said, lasting pain can lead to damage, hence don’t wait until the damage repair has a complete null chance, rather reach out to your doctor to understand more about the concept of SCS so that you can get treated in no time.

Pain is a perception by the nervous system. When a painful stimulus is applied to a body part, the nerve endings of that part will send the sensation all the way to the brain where it is perceived as pain. If the pain is experienced by the legs or hands, then the sensation travels via the spinal cord to be perceived as pain. In case of people suffering from nerve problems, there could be cases of chronic pain, therefore conservative treatment measures may fail at times. In these people, though the pain source cannot be reduced, the perception can be reduced. This is exactly what a spinal cord stimulator does, it masks the signals that are reaching the brain, and thereby reduces the perception of pain.
What is it and how does it work?
Spinal cord stimulator is implanted in patients with chronic intractable neuropathic pain when other conservative or surgical treatment has failed. Trial electrode/s are placed in the outer covering (epidural space) of the spinal cord, higher than the level of pain. Correct placement of electrode is confirmed by stimulating the electrodes through an external generator and different modes/intensity of current are tried to get best pain relief. Pain message is electrical in nature and reaches pain center in brain through multiple relays. Spinal cord stimulator converts electrical energy to a different feeling called neuromodulation and usually pleasant. Upon relief of atleast 60%, the device is implanted in the body like pacemaker for heart. An external remote device allows the device to be used when it is required. It is very safe and free from sideeffects of medications as no drug is used with this device.

The human body is so amazing yet sometimes, it is delicate. The condition of cervical spondylitis is one of the examples of this being the case. It is also known as cervical disc disease and is reputed to cause a pretty large amount of pain! That being said, it is not as if this pain cannot be reduced. After all, physiotherapy can make almost any situation better and this is pretty much the case with cervical spondylitis, as well!

Traditionally, people resort to hearing aids in order to take care of their auditory problems. The perception of hearing reduces as age progresses and people find it absolutely necessary to come up with ways by which they can improve their hearing. However, cochlear implants have become extremely popular because of the method that it uses in comparison to the traditional methods of hearing aids.
What is a cochlear implant?
A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants bypass the damaged hair cells of the inner ear (cochlea) to provide sound signals to the brain.
Who can they help?
The cochlear implant technology can help people who:
Many people have cochlear devices in both ears (bilateral). Listening with two ears can improve your ability to identify the direction of sound and separate the sounds you want to hear from those you don’t.
What are the benefits of a cochlear implant?
Many adults with cochlear implants report that they:
How is a cochlear implant different from a hearing aid?
A cochlear implant is very different from a hearing aid and is appropriate for individuals for whom hearing aids fail to provide benefit. A hearing aid makes sounds louder. Sound still travels through all the portions of the ear (outer ear, middle ear, inner ear) to the hearing nerve. A cochlear implant bypasses these structures and directly stimulates the hearing nerve with electrical energy. Because hearing aids amplify sounds and rely on the hearing system to convey the message, people with severe to profound hearing loss may be able to hear, but not understand speech well. The main objective of a cochlear implant is to improve speech understanding in quiet. Clarity with a cochlear implant is usually better than a hearing aid because the implant does not make sounds louder but delivers them to the hearing nerve.
There are a number of symptoms, which people should be looking out for before concluding that they have a hearing disorder:
If you wish to discuss about any specific problem, you can consult an ENT specialist.
Overactive bladder, also known as OAB, is a condition where sudden involuntary contractions of the urinary bladder's muscular walls cause bladder storage dysfunction. It leads to sudden and frequent urges to urinate (urinary urgency), as well as unintentional leakage or urine (urinary incontinence).
This is a condition that affects both men and women and causes tremendous discomfort in nearly every aspect of daily life. The specific causes of OAB vary from case to case but it is generally attributed to infection of the urinary tract or dysfunction of the nervous system. The symptoms are intensified by unhealthy lifestyle choices such as overindulging in caffeinated drinks, spicy foods and alcohol.
There are several ways in which you can deal with the problem of OAB, depending on the nature of the case. It is necessary for you to consult a urologist for a detailed diagnosis to formulate the best treatment option.
Following are the most effective remedies to treat an overactive bladder:
1. Lifestyle Modifications: Also known as behavioral therapy, this is the first step in the treatment of OAB. It involves inculcating simple changes into everyday habits such as avoiding food and drinks that irritate the bladder, scheduling (and in some cases, practice delaying) bathroom visits, exercising the pelvic floor and bladder muscles, keeping a record of urinating habits in a 'bladder diary' for better understanding the problem, etc. You can incorporate these habits into everyday activities for an easy alleviation of the problem with absolutely no side effects.
Lower back pain is fast becoming an epidemic not just among elderly, but across all age groups. Primary causes of back pain are quite a few including lumbar hernia, disc degenerative disease (DDD), spondylosis etc., but the symptoms are usually the same excruciating pain in the lower region of the spine, followed by stiffness. Since back pain is caused due to a number of spinal problems, it manifests differently in different patients. The pain may be dull, burning or sharp. It could also be felt at a single point or over a broad area and could be accompanied by muscle spasms or stiffness or even shooting pain in one or both legs.
Back pain can also be differentiated according to time period:
Sometimes symptoms resolve on their own, but in many cases conservative treatment, such as physiotherapy, which often work better than surgery, becomes essential. Alternate therapies like surgery, acupressure, acupuncture as well as yoga and Ayurveda also help.
Physiotherapy - Exercises that work
Since the reason for low back pain is not always same, a patient’s treatment too should be tailored for his specific symptoms and condition. This is what the physiotherapist will do design an exercise plan based on the patient’s specific problem and its cause.
Physiotherapy exercises help support the back and strengthen muscles so that the spine is cushioned properly. This is why physiotherapy is relevant as a treatment for backache. Treatments like traction help in lengthening the spine and relieving compression of nerves that cause sciatica, radiating pain into legs largely due to lumbar herniation. If back pain is extreme, a patient will require physical therapy along with medication, which will help in managing pain and bringing inflammation down. But in the long term, being physically active, going for walks, sitting properly and maintaining a good posture will help the most. If you wish to discuss about any specific problem, you can consult a physiotherapist.
