After a tough workout session or a strenuous day at the office, your muscles may feel floppy and exhausted until you have given them a chance to rest. However, persistent muscle weakness with no apparent cause or explanation can be a sign of an underlying medical problem.

What causes muscle weakness?
Voluntary muscle contractions and movement are generated when the brain sends a signal through your spinal cord and nerves to the particular muscle. If there are any hindrances in the connections between them, it can result in muscle weakness. However hard you try, the muscle is such cases becomes abnormal.

Here are some common causes of muscle weakness:

Lack of Use: One of the most common causes of muscle weakness, lack of muscle fitness may occur as a result of a sedentary lifestyle. If the muscles are not used, then the fibers are partially replaced with fat.
Ageing: As we age, our muscles tend to get weaker and lose strength. Muscles become bulky and recovery times during injury are greater. However, with physical activity, it is still possible to increase the muscle power. So stay active and instill strength in your muscles.
Infections: Infections and inflammation can cause temporary muscle fatigue. Even though recovery is quick, if the infection is severe the weakness can last for some time. Without proper care, it can lead to permanent damage.
Pregnancy: During and just after pregnancy, high levels of steroid in the blood and low levels of iron can cause muscle tiredness. Lower back pain is common during pregnancy and all your muscles may feel floppy.
Chronic Diseases: With conditions of diabetes, heart disease, kidney disease and anemia, it can lead to muscle weakness by thwarting the essential blood or nutrient supply to the muscles. Also, chronic pain related ailments cause weakness.
Injuries: Injury or trauma such as sporting injuries, pulls and sprains can deter the muscles. Along with localized pain, it can also lead to muscle weakness if not taken care of properly.
Sleep Disorders: With disturbed or reduced sleep there is a general sense of tiredness that leads to fatigue in the muscles. Insomnia, anxiety, depression and other mental disorders also affect the muscles a great deal.
Conditions affecting Nerves: Conditions like Myasthenia gravis or motor neuron disease affects the nerves and thereby fail to relay signals to the muscles, leading to weakness.
Genetic disorder affecting muscles: There are also certain inherited diseases which can affect the muscles like muscular dystrophy.
Spine-related disorders: Conditions like slip disc and other disorders affect the muscles served by the irritated or compressed nerves of the spinal cord.

Muscle Weakness - 10 Common Reasons Behind 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.

Causes of Neck Pain and Diagnosis

Cervical spondylosis is an age related disorder affecting the discs and joints in your neck. The overuse of the bone and cartilage in the cervical spine of your neck leads to cervical spondylosis. While it is mostly caused by age, it can also be caused by other factors. Stiffness and severe, chronic pain are the most common problems with patients afflicted with cervical spondylosis. While in others, it might not cause problems and they can go about their daily activities.

Physiotherapy for Cervical Spondylosis
There is no cure for cervical spondylosis, but its symptoms can be treated with physiotherapy. If you have chronic pain in your neck, shoulder blades or arms, a physiotherapist can provide effective pain relief by strengthening your vertebrae and neck. This will improve your posture and prevent any relapse of the pain.

Firstly, the physiotherapist will evaluate your condition; check your reflexes and strength. Then, the physiotherapist will move on to the following treatments:

Stretching, strengthening and straightening exercises: Before beginning these exercises, your physiotherapist will first apply cold or heat to the affected area and then proceed with a deep tissue massage or electric stimulation. When your muscles are relaxed, the exercises will begin only then. These exercises are performed to strengthen the muscles in your neck. Through these, you will learn how to improve your range of movement and posture.
Neck traction: Pulling your head to stretch out your spine is called neck traction. This technique is used to improve movement and ease the pain. Traction is used to open the spaces between the vertebras gently in order to ease pressure on the distressed discs. Traction is done continuously or sporadically, with short periods of rest in between. If you cannot find the right physiotherapist to do this for you, there are devices to help you stretch your spine.
Cervical collars and pillows: Neck pillows or cervical pillows, are made to keep your neck steady while you sleep. Cervical collars are also called neck braces which are used to support the neck. While cervical collars have been proven to be quite beneficial, there isn t much evidence to support cervical pillows in treating cervical spondylosis. You can always consult your physiotherapist before purchasing a cervical pillow.

Cervical Spondylosis - How Physiotherapy Can Help Treat it?

A small piece of bone is known as a fragment and it is very common that an avulsion fracture also tends to damage the protrusions of bone to which the tendons attach. This basically means that the tendon or ligament will come away from the bone and it will take a small piece of bone with it. It is sometimes very hard to find out what type of injury you have and this is why knowing the causes and symptoms of an avulsion fracture are very helpful in determining exactly how severe the injury is. 
Here are the causes of an avulsion fracture.
Causes:
Explosive Landing: Athletes who tend to jump or land with great impact tend to get these most commonly. Therefore, it is crucial for your health that if you participate in such sports, you do follow the correct method of jumping.
Explosive Extension: Similar to how an athlete landing ferociously can get an avulsion fracture, someone who is extending the legs very violently and explosively during an exercise can also get an avulsion fracture. This is because the bone getting extended could very well damage the protrusions to which the tendons are attached. 
Symptoms:
These are the two main causes of an avulsion fracture. There are not many symptoms of an avulsion fracture. This is because an avulsion fracture can only be determined by an MRI or by an X-ray scan. Therefore it is nearly impossible to diagnose that you have an avulsion fracture without looking at the results of the tests performed on the part of your body. However, the way you got the fracture and especially the details of it are very good indications of whether you have an avulsion fracture or not.


Causes and Symptoms of Avulsion Fracture

Muscle sprains and ligament tears are one of the most common injuries that medical practitioners encounter on a regular basis. These injuries are painful and can also limit one s movement, needless to say. However, there are simple things that can be done as soon as the injury happens so that the impact of the injury can be reduced, the symptoms minimised, and recovery improved.

A sprain is a tear of the ligament. The ligament is responsible for connecting the tissue strands that connect the bone to the muscle. When this sprain affects the muscle or even the tendon, it is known as a strain.
Sprains are very common and can occur due to a fall, twist, or impact. Most commonly affected areas are the ankles and wrists. Sprains happen when there is a pull or a twist of the ankle or the joint. This is very common in athletes and can be caused by repetitive motions in the knees, wrists, elbows, etc.

The most common symptom is pain, swelling, limited movement, and sometimes bruising. The degree of these injuries depends on its severity. The most common ways to treat such injuries are as follows.

RICE therapy: RICE is an acronym for rest, ice, compress, and elevate. Rest the affected area immediately by stopping any further activity. Ice the area using an ice wrap, with the ice cubes wrapped in a towel or a cotton cloth. Repeat this exercise if possible for every 20 minutes. This will reduce the swelling and pain. Compress the area using a sling or a wrap. This will help in reducing the swelling. Elevate the affected area if possible above the heart. This will help control the blood flow and thereby reduce the swelling and pain.
Pain control: If there is pain that needs medication, go for the non-steroidal drugs like ibuprofen or acetaminophen. If it is a child that is injured, it is advisable to give non-aspirin ones.
Seek professional help: Most sprains can be self-limiting over a couple of days. However, it is advisable to seek medical help if there is significant pain, swelling, or numbness, open wounds or bruises, or inability to move the joint.
The doctor may decide to do the following.

Scanning or imaging to rule out any internal hard/soft tissue injury like fracture or tear
Immobilise the joint with a splint or a cast
Start physical therapy if there is severe pain and immobility
Surgical repair if there is a ligament injury
A word of caution to athletes or people who are very active physically is to go easy on the joint. In an eagerness to quickly get back to their routine, more and severe damage may be caused. This can be avoided by allowing time for complete healing.
