Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision. 

Hot & Cold Therapy - How It Can Treat Pain?

Neck pain is fairly common among adults. It results from the soft tissues such as ligaments, muscles and tendons. It can result from spasms and muscle strain from neck problems such as disc degeneration and spinal stenosis. Be it a chronic pain or a sudden one, addressing it is important to get on with the daily office life. 

Here is a list of some quick solutions, which when followed can give considerable relief from the pain:

Computer should be at eye level: While sitting at it you must ensure that the middle of the computer screen is parallel to the eye. If it is required that you bend your neck to view the screen, then you should adjust the screen, without bending your neck. This happens most often while working with a laptop. The chair length can be adjusted to fix this problem.
Refrain from neck straining while typing: If typing requires straining the neck, it should be ensured that the same doesn t happen. This is the case while texting in a mobile. A better solution is to fix this is to take the mobile at a level which does not require the neck bend down. It will ensure that the joints and discs of the neck are not stressed.
Use headset: If the work demands longer time on the phone, instead of bending the neck it makes sense to use a headset. Practicing the chin tuck exercise can help in this case. This exercise can strengthen the soft muscles of the neck. It also maintains the alignment of the head and the shoulder.
Stay hydrated: Enough hydration is necessary to ensure spinal alignment and disc height. Hydration also takes a eases the spine and relaxes the soft muscles. A practice of adequate hydration throughout the day can help stop the degeneration of the cervical disc. While drinking water is a matter of practice, keeping a water bottle serves as a constant reminder to drink it throughout the day. Keeping an alarm after 2 hours also serves as a constant reminder to drink water.
Carrying weight: One common mistake committed by most people is to carry weight with one hand. Since the load doesn t distribute evenly, it strains the neck muscles causing pain. It should be ensured that the office briefcase or the heavy purse is carried with equal stress on both the shoulders. This will ensure a painless day at the office.
Maintaining a good posture: Poor sitting or walking posture is often the cause of neck pain. While sitting it should be ensured that the back is straight and rests in the chair once in awhile. The neck and head should fall in a line while working.

Neck Pain at Work - 6 Tips to Help You Prevent it

Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Knee Replacement

Neck pain is a common medical condition, which can be easily treated if proper care and medications are taken. It usually occurs due to strained neck muscles, often caused bad posture, though there might be other causes as well. Rarely, neck pain can be a symptom of a more serious problem as the condition is relatively mild in nature. The symptoms of a neck pain are very obvious which refers to any kind of discomfort in moving your neck on a daily basis. Along with this you might also have headache, stiffness of the head and muscle tightness. Some of the most common causative factors of neck pain are listed below.

Muscle strains
A muscle strain generally happens when you exert too much pressure on your neck continuously for long periods. It also happens when you have your neck fixed in the same position for long hours of the day. Muscle strains in the neck may occur when you keep your neck bent in the wrong way while doing activities like reading a book, looking at your mobile phone or working over your laptop for extended hours.

Worn joints
Just like all the other bodily joints, the neck joint also tends to wither and degrade with age. This phenomena is known as the wear and tear of the joints. The bones of the neck joint tend to wither with time, thereby making your joint frail and exposing it to various pains and medical conditions.

Nerve compression
Nerve compression is a medical symptom whereby, there is excessive pressure put on one particular nerve in the body. Herniated discs or bone spurs in the vertebrae of your neck can press on the nerves branching out from the spinal cord, hence causing a long lasting neck pain. Damage caused from a nerve compression may be minor or severe depending on the pressure applied. It may cause temporary or long lasting problems depending on the degree of damage caused. The earlier you get a diagnosis and treatment for nerve compression, more quickly you will find relief.

Whiplash
Neck related injuries are common phases of pain and discomfort caused due to an external damage to the neck as a result of a tragic sports related or vehicular accident. A neck injury is also known as a whiplash and it refers to an injury due to forceful, rapid back-and-forth movement of the neck, like the cracking of a whip. Whiplash mostly occurs during accidents, physical abuse or other trauma.

4 Common Causes of Neck Pain

Knee pain or injuries are very common and have numerous causes. Knee pain can emerge from delicate tissue wounds like ligament sprains and muscle strains. Bone conditions like knee joint pain, Osgood Schlatters, and biomechanical dysfunction can also cause knee pain. Treatment can include basic knee mobilization techniques, taping, massages or knee strengthening exercises completely through a careful recovery method after knee replacement or reconstruction.

Physiotherapy can help you overcome the pain and increase your strength and flexibility. A physiotherapist can suggest you a number of treatments and also help you understand your issue and get you back to your everyday routine. Physiotherapists are said to be successful in getting rid of the source of the knee pain by diagnosing a cause. This includes tightness around the knee and treating it with stretching and exercises.

Following are some of the exercises a physiotherapist might generally recommend for knee pain:

Hamstring stretch: Stretching keeps you flexible and increases your scope of movement, or how far you can move your joints in different directions. It additionally helps you reduce your chances of injuries and pain. Continuously warm up with a five minute walk first. Lie down when you are prepared to stretch your hamstring. Circle a bed sheet around your right foot, use the sheet to pull the leg up and hold for twenty seconds and then lower the leg. Repeat twice and switch legs.
Calf stretch: Use a chair for balance. Bend your left leg. Step back with your right leg and gradually straighten it behind you. Press your left heel toward the floor. You should feel the stretch in the calf of your back leg. Hold for 20 seconds. Repeat twice and then switch legs.
Straight leg raise: It helps build muscle strength to give support to the weak joints. Lie on the floor. Twist your left knee, foot on the floor. Keep the right leg straight, toes pointed up. Tighten your thigh muscles and raise your right leg.
Quad set: With these, you don't raise your leg. Just tighten the thigh muscles, also called the quadriceps, of one leg at once. Begin by lying on the floor. Keep both legs on the ground, loose. Flex and hold the left leg tense for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Cushion squeeze: This move strengthens your legs from the inside so that they can support the knees. Lie on your back, both knees facing inwards. Place a cushion or a pillow between the knees. Press your knees together, squishing the cushion between them. Hold for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Heel raise: Stand tall and hold the back of a seat for support. Lift your heels off the ground and rise on the toes of both feet. Hold for three seconds. Gradually lower both heels to the ground. Do three sets of ten repetitions. 

Knee Pain - How Physiotherapy Can Heal Knee Pain?

Problems with the arteries and veins present in the hands or legs can lead to vascular disorders. The arteries carry blood from the heart to other parts of the body in order to deliver nutrients and oxygen. The veins carry the blood back to the heart, after the nutrients have been used up. If these blood vessels of the arteries or veins become blocked or narrowed, it can lead to a vascular blockage.

A vascular blockage that occurs in the hands or legs comes under the category of Peripheral Artery Disease or PAD. These type of disorders are less common in the upper extremities of the arms or hands than in the lower extremities of legs. Few of the signs for the same are:

Pain and difficulty in movement due to decreased blood flow
Numbness or weakness of leg or fingertips
Sores on the toes or feet
If the blockage is deep, symptoms of redness, swelling, extreme pain or cramping can be experienced
Abnormal color changes in the fingertips
Ulcers or wounds that don t heal
Skin sensitivity problems when in cold temperatures
How can it be diagnosed?
The blockage can be detected by various methods namely-

Physical Examination   Your doctor may find decreased pulse at armpit, wrist or fingers, full veins, masses, wounds or gangrene.
Doppler or Ultrasound examination to determine the blood flow in the arteries and veins
MRI Scan of the affected area to pay special attention to the blood vessels
Cold Stress Test
Arteriography to show clear blood vessel details
Angiography to map blockages and narrowing of the arteries
What are the Risk Factors for Peripheral Artery Disease?
An individual is at risk for developing vascular blockages in the hands or legs if one or more of the following factors are present:

Smoking
Diabetes
Heredity Factors   A personal or family history of blood vessel disease
High blood pressure
High cholesterol
Aging   People aged above 50 years and older are more prone to vascular blockage
Can it be treated?
Treatments for vascular blockage can vary depending on the age, cause of the blockage, intensity and overall well-being.

Treatments can include:

Self-care   Reducing risk factors and making lifestyle changes to quit smoking, sedentary life or diabetes, blood pressure and cholesterol management can reverse symptoms of vascular disease.
Medications   A variety of drugs can be prescribed to lower the risk and progression of narrowing blood vessels or prevent blood clotting.
Interventional Procedures   Minimally invasive surgery like saloon angioplasty, stenting or removal of artery plaque build-up.
Surgery   If the blockage is severe, surgery may be performed to lessen the vessel narrowing, reconstruct the artery or tie it off, depending on the circumstances.
