Muscle atrophy is the wasting or thinning of muscle mass, which can be caused by muscle disuse or neurogenic conditions. It can lead to reduced muscle mass, weakness, numbness, and tingling in the limbs. While muscle atrophy itself does not directly cause joint popping, the associated symptoms of muscle weakness and tightness can contribute to joint instability and increased pressure within the joints, potentially resulting in joint popping. Joint popping is typically harmless and can be caused by various factors, including gas escaping from the joints, tight tendons or ligaments, and cartilage wear and tear. However, if joint popping is accompanied by pain, swelling, or difficulty moving the joint, it may indicate underlying issues such as arthritis, tendinitis, or bursitis, and medical attention should be sought.

What You'll Learn
Muscle atrophy due to inactivity
Muscle atrophy is the wasting or thinning of muscle mass. It can be caused by muscle disuse or neurogenic conditions. Muscle atrophy due to inactivity can occur if a person remains immobile while recovering from an injury or illness. This type of atrophy is reversible with regular exercise and physical therapy.
Disuse atrophy occurs when muscles are not used enough. If you stop using your muscles, your body will break them down to conserve energy, causing a decrease in size and strength. This can happen when leading a sedentary lifestyle, not getting enough exercise, or sitting at a desk job all day. It can also be caused by certain genetic disorders, such as muscular dystrophy or Charcot-Marie-Tooth disease, or by conditions that limit mobility, such as stroke or dermatomyositis. Age-related atrophy, or sarcopenia, is another form of disuse atrophy.
To treat disuse atrophy, healthcare providers may recommend regular exercise, physical therapy, or an exercise plan. Even if you cannot actively move certain joints, you can still perform exercises wearing a splint or brace. A healthy diet and nutritional supplements may also be suggested.
Neurogenic atrophy, on the other hand, is caused by nerve problems or diseases that affect the nerves connecting to the muscles. When these nerves are damaged, they cannot trigger muscle contractions, leading to a decrease in muscle size and strength. Neurogenic atrophy can sometimes be treated with a special type of physical therapy called electrical stimulation, where electrodes are placed on the skin to send electrical impulses to the nerves and muscles.
While joint popping is generally harmless, it can be caused by tight muscles or tendons. This can be addressed by gently stretching the affected joint and surrounding muscles. Physical therapy can also help reduce cracking and popping in the joints.

Neurogenic atrophy
Muscle atrophy is the wasting or thinning of muscle mass. It can be caused by muscle disuse or neurogenic conditions. Neurogenic atrophy is a type of muscle atrophy that occurs due to nerve problems or nerve-related diseases. When nerves are damaged, they cannot trigger the muscle contractions necessary for muscle activity. As a result, the muscles do not contract, and the body begins to break them down, leading to a decrease in muscle size and strength.
- Amyotrophic lateral sclerosis (ALS)
- Guillain-Barre syndrome
- Carpal tunnel syndrome
- Spinal cord injury
- Multiple sclerosis
- Polio
- Myositis
The symptoms of neurogenic atrophy are similar to those of general muscle atrophy, including a decrease in muscle mass, with one limb often appearing smaller than the other. Individuals may also experience numbness, weakness, and tingling in their limbs, as well as trouble walking or balancing. In some cases, neurogenic atrophy may cause difficulty swallowing or speaking.
The treatment for neurogenic atrophy depends on the underlying cause and the severity of the condition. Unlike disuse atrophy, neurogenic atrophy typically cannot be reversed due to the physical damage to the nerves. However, it can sometimes be managed with a specific type of physical therapy called electrical stimulation. This involves placing electrodes on the skin over the affected muscles to send electrical impulses to the nerves and muscles. These impulses artificially stimulate the muscles, helping to maintain muscle mass and strength.
While muscle atrophy itself can lead to a loss of movement or strength, it is not directly mentioned as a cause of joint popping. However, joint popping is generally harmless and can be caused by tight muscles or tendons moving over a bony structure. Joint cracking and popping are often associated with gas escaping and the stretching and releasing of ligaments and tendons. In most cases, joint popping is not a cause for concern unless accompanied by pain, swelling, or potential fluid build-up.

Joint popping causes
While joint popping is usually harmless, there are several reasons why your joints might pop. One common cause is gas escaping from the synovial fluid that surrounds the joint, which can happen when you crack your knuckles. This is known as crepitus, which can also be caused by air seeping into the soft tissues around the joint and forming bubbles. When you bend the joint, these bubbles burst, resulting in a cracking or popping sound. Another possible cause of joint popping is the rapid stretching of ligaments or tendons.
In some cases, joint popping can be a sign of wear and tear or injury. If you experience pain, swelling, or pressure in the joint along with popping, it is recommended to consult a healthcare provider. Conditions such as osteoarthritis, patellofemoral pain syndrome (PFS), or meniscus tears can cause joint popping and pain. However, joint popping by itself is typically not a cause for concern and is quite common.
Chiropractic adjustments can also cause joint popping. This type of treatment aims to reduce pain and help bones return to their proper position. While it is normal to hear popping sounds during these adjustments, you should consult a healthcare provider if you experience pain after the procedure. Additionally, while habitual knuckle-cracking has not been proven to cause arthritis, it can lead to a loss of grip strength and swollen hands.
To reduce joint popping, it is recommended to stay active, practice good posture, and wear proper gear during sports or other physical activities to protect your joints. Gentle stretching of the affected joint and surrounding muscles can also help reduce popping. If you are experiencing pain or other symptoms along with joint popping, a healthcare provider can help diagnose and treat the underlying cause.

Joint popping treatment
Although joint popping is usually harmless, it can sometimes indicate an underlying issue that requires medical attention. It is recommended that you consult a healthcare provider if you experience pain, swelling, or potential fluid build-up alongside joint popping.
Non-invasive treatments
- Bracing or splinting: Bracing can help align the joint, allowing injuries to heal.
- Physical therapy: Tailored physical therapy plans can help manage joint popping and improve joint stability.
- Custom orthotics: Special shoe inserts can stabilize the foot and knee, providing pain relief and improved mobility.
- Pain relief: Proper pain management can eliminate discomfort and inflammation, enabling a safe return to physical activity.
- Home remedies: Taking anti-inflammatory medications or using the RICE method (rest, ice, compression, and elevation) can help alleviate joint popping symptoms.
Surgical treatments
In some cases, joint popping may require more invasive treatments, such as:
- Arthroscopic surgery: A minimally invasive procedure that uses small instruments inserted through tiny incisions to access and treat the joint.
- Debridement: A type of minimally invasive surgery where the surgeon smooths damaged cartilage to reduce rubbing and improve joint movement.
- Joint replacement: For advanced arthritis or joint damage, joint replacement surgery involves implanting an artificial joint in place of a damaged one.
It is important to consult a healthcare professional to determine the most appropriate treatment plan for your specific condition.

Joint popping and arthritis
While joint popping is usually harmless, it can sometimes be indicative of arthritis. Arthritis refers to inflammation of the joints, which causes pain and stiffness. This can limit a person's mobility, potentially leading to muscle disuse and atrophy.
Joint popping is very common, and most people will experience it in their lifetime. Orthopaedic surgeon Kim Stearns, MD, notes that "It’s a normal, common occurrence". The cracking and popping noises are often just gas bubbles bursting within the synovial fluid that surrounds the joint. This fluid contains gases like oxygen, nitrogen, and carbon dioxide, which are released when a joint is cracked.
However, arthritis can also cause joints to crack and pop. Osteoarthritis (OA), for example, can cause decreased cartilage and painful, swollen joints. If you are experiencing pain, swelling, or stiffness alongside joint popping, it is important to consult a healthcare provider. They can advise treatments to help reduce joint noises, from home remedies to physical therapy.
While joint popping on its own is not a cause for concern, it may be indicative of an underlying issue when coupled with pain or swelling. In this case, it is important to seek medical advice to determine the cause of the symptoms.
