There are three main factors that contribute to joint stability:
- Size, shape, and arrangement of the articular surface: The articular surface is the connection of two bones. How the articulation is designed affects just how much your joint can move and how stable it is.
- Ligaments: All joints are surrounded by ligaments, which are connective tissues that hold a joint together. ...
- Tone: Muscle tone can decrease over time, especially without proper exercise. ...
What is meant by joint stability?
Otherwise known as the range of uninhibited movement around a joint. Joint Stability is defined as the ability to maintain or control joint movement or position. Stability is achieved by the coordinating actions of surrounding tissues and the neuromuscular system.
How do ligaments affect the stability of a joint?
As a general rule, the more ligaments a joint has, and the tighter they are, the more stable the joint is. However, tight ligaments restrict movement, and this is why extra stability of a joint comes at the cost of loss of mobility. If disproportionate, inappropriate or repeated stress is applied to ligaments, they can stretch,...
What are the factors affecting joint stability and mobility?
While many of the mechanical and anatomic factors affecting joint stability and mobility have been discussed, such factors as stress, flexibility, viscosity, elasticity, plasticity, stiffness, strain, fatigue, and deformation characteristics of pertinent tissues require further definition and clarification.
How can I improve the stability of my joints?
Training the muscles around a joint helps to improve its stability. The stronger the muscles, the more control they have over the movements of the joint. A muscle imbalance can also lead to joint laxity. Post injury, training will generally involve both flexibility and strength training of a joint.
What causes loss of stability in a joint?
Instability occurs when the tissues, ligaments, and muscles surrounding a joint are weak, torn, overstretched, or otherwise stressed. If you have unstable joints, it can cause an unhealthy range of motion in your joint, further leading to joint fracturing, dislocation, or other injuries to the joints.
What factors influence stability at synovial joint?
These include:Shape of articular surfaces (how close they fit)Strength and tension of capsule and ligaments (dependent on position)Arrangement and tension of muscles.Contact with soft parts such as adipose tissue.Hormones.More items...•
What helps with joint stability?
Stretching and strengthening exercises can help keep your joint from stiffening up and can improve stability. Plus, stronger muscles can help absorb some of the stress and strain that's placed on a joint.
What affects joint mobility?
Factors that cannot be changed such as age and sex of the athlete should be considered when assessing and designing a flexibility program. Other factors affecting flexibility and joint mobility that can be modified to improve flexibility include injury, tissue bulk, quality of movement, and activity level.
How does exercise increase the stability of joints?
“Exercise strengthens the muscles, ligaments and tendons surrounding the joints,” says Sterling. “When these tissues are strong, they act like a brace to protect the joint,” and lessen pressure on weakened joints.
What structures make joints stable?

Which synovial joint is the most stable?
Answer and Explanation: The class of synovial joints that are the most stable are the gliding joints. This is because the bones of a gliding joint slide past each other in any direction along a single plane created by their two flat surfaces.
What factors affect ROM?
Factors affecting the final range of motion are discussed belowGender. ... Age. ... Body mass index. ... Type of disease. ... Preoperative range of motion. ... Preoperative flexion deformity and postoperative range of motion. ... Patella resurfacing and tourniquet protocol. ... Scores.
What factors limit the range of movement of a joint?
When a joint does not move fully and easily in its normal manner it is considered to have a limited range of motion. Motion may be limited by a mechanical problem within the joint, swelling of tissue around the joint, spasticity of the muscles, pain or disease.
What specific types of tissues help reinforce the stability of the hip joint?
Ligaments and Labrum Ligaments, soft tissue structures that connect bone to bone, reinforce the capsule. The capsule and ligaments provide passive stability to the hip joint but allow movements in different planes. The labrum of the hip is a fibrocartilaginous structure that is located at the level of the acetabulum.
Why is stability important in joints?
The stability of joints is a topic of great clinical importance; it explains why some joints are more prone to dislocation and injury than others. It also underlies the clinical basis of treating joint injuries.
Which joint is more unstable?
For example, in the shoulder joint, the humeral head of the upper arm is disproportionately larger than the glenoid fossa of the scapula that it sits in – making the joint more unstable, as there is less contact between the bones.
What muscles help stabilize a joint?
The tone of the surrounding muscles contributes greatly to the stability of a joint. A good example of this is the support provided by the rotator cuff muscles, which keep the head of the humerus in the shallow glenoid cavity of the scapula. If there is a loss of tone, such as in old age or stroke, the shoulder can dislocate.
Which muscle acts to stablise the shoulder joint?
Fig 2 – The rotator cuff muscles, which act to stablise the shoulder joint.
What is the purpose of ligaments in a joint?
The ligaments of a joint prevent excessive movement that could damage the joint. As a general rule, the more ligaments a joint has, and the tighter they are, the more stable the joint is.
Why are sportspeople more susceptible to ligament injuries?
If disproportionate, inappropriate or repeated stress is applied to ligaments, they can stretch, tear or even damage the bone they attach to – this is why sportspeople are more susceptible to ligament injuries. The tone of the surrounding muscles contributes greatly to the stability of a joint.
Which joint is more stable, the hip or the shoulder?
In contrast, the acetabulum of the pelvis fully encompasses the femoral head, and this makes the hip-joint far more stable. However, whilst the hip is more stable, the shoulder has a greater range of movement. Each joint has this trade-off that is particular to its function.

What is joint stability?
Joint stability is the ability to control joint movement within the proper range of motion. This stability comes from the soft tissue and muscles that surround and support the joint. At the end of the day, stability is what keeps your joints safe.
What is the connection between a joint and a ligament?
Ligaments: All joints are surrounded by ligaments, which are connective tissues that hold a joint together. The tighter a ligament is, the more stable a joint will be, but that also impacts how much the joint can move.
Why does muscle tone decrease over time?
Tone: Muscle tone can decrease over time, especially without proper exercise. This causes joints to be less stable and more prone to injury. Muscle tone imbalance can also hurt your joint stability, so it’s important that you always train properly.
How to know if you have a problem with your joints?
Understand the importance of joint stability is the first step to knowing if you have a problem. Many people first notice tightness around their joints, which is one of the first signs of instability.
What is the difference between joint stability and mobility?
Simply speaking, mobility is the ability of a joint to move freely through its range of motion before being restricted by surrounding tissues. Joint stability, however, is the ability to control that movement. So whenever your body feels unstable, your mobility won’t be as great as it could be.
Is joint stability or mobility more important?
Many people argue about whether joint stability or mobility is more important. Here’s what we think: joint stability and mobility are equally important. You can’t expect to have a full range of motion by just focusing on one or the other. Simply speaking, mobility is the ability of a joint to move freely through its range ...
How to improve stability of joints?
Improving stability. Training the muscles around a joint helps to improve its stability. The stronger the muscles, the more control they have over the movements of the joint. A muscle imbalance can also lead to joint laxity. Post injury, training will generally involve both flexibility and strength training of a joint.
What are the parts of a joint that help to increase the surface area of the joint?
This includes the bones that make up the joint, cartilage, ligaments, tendons, and muscles. Cartilage on the bony surfaces that comprise the joint help to increase the surface area of the joint (thereby increasing the stability), and/or cushion the joint. Muscles, tendons, and ligaments help to create support around the joint.
What is the synovial joint?
Synovial joints are characterized by the synovial fluid present in the joint capsule that helps to lubricate the joint. The stability of a joint relies on the shape of the joint itself as well as its surrounding structures.
What are condyloid joints?
Condyloid joints are also referred to as ellipsoidal joints. The base of each finger is a condyloid joint. 3. Saddle Joints: These joints are made of two concave and convex surfaces that intersect. Saddle joints allow for flexion, extension, and lateral movement.
What is the base of a saddle joint?
The base of the thumb is an example of a saddle joint.
Which joint allows for the greatest range of motion?
1. Ball and Socket Joints: These joints allow for the greatest range of motion. The joint involves a ball fitting into a concave surface. Because these joints allow for more motion, they are at greater risk for instability. Ball and socket joints allow for movement in many planes, and circumduction.
Which type of joint allows for rotation?
Pivot Joints: This type of joint allows for rotation. Unlike many other synovial joints, it does not allow for any flexion or extension. The first two cervical bones (the atlas & axis) form a pivot joint. The atlas sits on top of the axis and enables a “no” movement of the head (left & right rotation)
