Horizontal flexion: Refers to movement where the angle between two bones decreases and on the horizontal plane. Click to see full answer. Likewise, people ask, what is flexion of shoulder? A shoulder flexion is when you move your arms anywhere from a resting position by your sides to straight above your head.
How to improve shoulder flexion?
- Stand tall with a dumbbell in each hand.
- Curl the dumbbells up to your shoulders and rest the weighted part on your shoulders with the other side of the dumbbell facing in front of you.
- Start with your hands in a neutral position and your knuckles facing to the outside.
What is the normal shoulder flexion?
- Split into anterior and posterior divisions by the biceps tendon.
- Anterior portion limits extension while the posterior portion limits flexion.
- Both divisions limit inferior and posterior translation of the humeral head.
- Helps to support the weight of the resting arm against gravity.

What causes horizontal vs vertical bone loss?
adjacent to the tooth root. Horizontal bone loss usually has minimal "pocket formation" whereas vertical bone loss has huge "pockets" requiring surgical intervention. There are several established facts about periodontal microbiology. Periodontal disease is caused by bacteria.
What is horizontal flexion?
Horizontal flexion occurs when the arm is pulled across the chest when it is parallel to the floor. Horizontal extension occurs when the arm is returned from the above position out to the side.
What muscles cause shoulder horizontal flexion?
The pectoralis major has the largest horizontal flexion moment arm with the humerus elevated 90 degrees, whereas the posterior deltoid and infraspinatus have the largest horizontal extension moment arms in this plane.
Is horizontal flexion the same as horizontal adduction?
Horizontal Adduction (flexion) – Horizontal motion that results in movement toward the midline. Horizontal Abduction (extension) – Horizontal motion that results in movement away from the midline.
What is horizontal adduction of shoulder?
This is called horizontal shoulder adduction. It is when your arms move in toward the body along the horizontal or transverse plane. The main muscles involved in horizontal shoulder adduction are the upper fibers of the pectoralis major and the anterior fibers of the deltoids.
Which muscle is the prime mover during horizontal flexion of the shoulder?
Pectoralis majorPectoralis major is the muscle which acts as prime mover in shoulder flexion.
What muscles perform shoulder flexion?
The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis. For a shoulder extension, your body uses the latissimus dorsi, teres major and minor and posterior deltoid muscles.
What plane is horizontal flexion in?
The third plane of motion bisects the body into top and bottom halves and is called the transverse plane (AKA the horizontal plane).
What is horizontal abduction of shoulder?

In this particular case we're reading 20 degrees of horizontal abduction where normal range is 0 to 45 degrees.
What is an example of horizontal adduction?
Brent Brookbush This is not uniform in all textbooks, although it should be "Horizontal Adduction" is adduction (bone moving closer to midline) in the horizontal plane. Example, bringing your hands together in front of your chest, as you do during a chest flye.
What is horizontal abduction movement?
Horizonal abduction is the movement of the arms from horizontally across the body. Starting from a position where the arms are straight to the front (shoulders flexed at 90 degrees), moving in the transverse plane to end in a position where the arms are straight out to the side (flexed at 90 degrees).
What is the difference between horizontal adduction and adduction?
Brent Brookbush This is not uniform in all textbooks, although it should be "Horizontal Adduction" is adduction (bone moving closer to midline) in the horizontal plane. Example, bringing your hands together in front of your chest, as you do during a chest flye.
What is the difference between horizontal adduction and abduction?
Horizontal abduction (arm behind torso; C) occurs early in the throwing motion, whereas horizontal adduction (arm in front of torso) occurs from the end of late cocking and beyond.
What is shoulder flexion?
Shoulder Flexion Definition. In shoulder flexion, the shoulder joint angle decreases, specifically when you move your arm forward. For example, when you do a front raise exercise or close grip shoulder press, your arm is rising forward. This forward movement is called flexion of the shoulder. The shoulder flexion prime movers are:
Which plane of motion is the shoulder in?
Shoulder Planes of Movement. All flexion of the shoulder happens in the Sagittal Plane . In addition, all flexion and extension of the shoulder also occur in the Sagittal plane. Last, you must know that all flexion and extension of any joint occurs in the sagittal plane .
What plane of motion does NASM expect you to know?
Any time that you see flexion or extension, know that the joint movement is taking place in the sagittal plane. For now, that is all you need to know. We will soon explain the planes of movement and the degrees of freedom.
How far can you go in flexion?
Most likely, the furthest you can go is till your arms are pointing directly overhead, which is a shoulder flexion range of motion of 180 degrees.
Where does shoulder adduction occur?
Also, shoulder adduction and shoulder abduction happen in the frontal plane. All adduction and abduction along with lateral flexion (side bends) occur in the frontal plane. Therefore, shoulder abduction and adduction are in the second degree of freedom, the frontal plane.
How many degrees of freedom are there in the shoulder joint?
For example, in the case of the shoulder joint, we can say that there are three degrees of freedom.
Which plane does shoulder extension occur in?
And the same is true for shoulder extension which also occurs in the sagittal plane.
Where does horizontal flexion occur?
Horizontal flexion: this only happens at the shoulder joint and occurs in the transverse plane. When an arm is held out to the side parallel to the floor and then pulled across the chest, that would be horizontal flexion.
What is horizontal extension?
Horizontal extension: Refers to movement where the angle between two bones increases and occurs on the horizontal plane.
What is lateral extension?
Also, what is lateral extension? Lateral Extension – When referenced from anatomical position, extension is increasing the angle at the joint, or movement back to anatomical position. (this motion is also in the frontal plane) See Video Demo: Lateral Flexion Lumbar Spine.
What Muscles are Used in Shoulder Flexion?
The shoulder flexion muscles include the deltoid, the pectoralis major, and the coracobrachialis. The anterior head of the deltoid and the clavicular head f the pectoralis major are the prime movers for shoulder flexion, and the coracobrachialis is the synergist muscle, which means that it assists the prime movers. Here’s how these muscles work in your body.
How to improve flexibility in shoulder?
Stretching can help improve flexibility and help prevent injury. Incorporate these shoulder stretches into your cool-down following any workout that incorporates shoulder flexion exercises.
What is front shoulder raise?
The front shoulder raise is a simple shoulder flexion exercise that can be scaled for beginners or more advanced athletes by adjusting the weight or level of resistance.
What muscle is the pectoralis major?
Commonly referred to as the “pecs,” the pectoralis major is the large, fan-shaped chest muscle that originates from the sternum and collarbone and inserts into the humerus. In addition to playing a role in shoulder flexion, the pectoralis major functions to move the arm toward the body’s midline, and inwardly rotate the arm.
How to stretch the deltoid and pectoralis muscles?
You’ll feel this simple, but effective stretch in the deltoid and pectoralis major muscles. Stand with your feet hip-width apart. Reach both hands behind your back and interlace the fingers. Looking up, raise your chest toward the ceiling as you pull your hands toward the floor and straighten your arms.
How to get your arms to be straight?
Keeping your core engaged and your arms straight, raise your arms in front of you until your hands are shoulder height, keeping your palms facing each other. Pause, then slowly lower the dumbbells to the starting position and repeat.
What are the three parts of the deltoid?
The deltoid, the rounded, triangle-shaped muscle located on top of the shoulder, consists of three “heads,” or parts: the anterior (front) head, the lateral (middle) head, and the posterior (back) head. These heads originate from the collarbone and shoulder blades and insert into the humerus (the upper arm bone). While all three heads work together to move the arm, the anterior head is primarily responsible for shoulder flexion. The lateral head moves the arm away from the body, and the posterior head is responsible for extension.
What is shoulder flexion?
Shoulder flexion. Flexion is a movement that decreases the angle between the two parts that the joint is connecting. If you hold your arms straight and palms against your sides and raise your arms in front of your body to point your hands at something in front of you, you’re practicing flexion. A normal range of motion for shoulder flexion is 180 ...
What is the range of motion of the shoulder?
A normal range of motion for shoulder flexion is 180 degrees. This involves moving your arms from palms against the side of your body to the highest point you can raise your arms over your head.
How to rotate your shoulder?
With your arms at your sides, palms facing your body, bend your elbows 90 degrees. Keeping your elbows against your body swing your forearms away from your body. This is lateral rotation — also referred to as external rotation — and the normal range of motion for a healthy shoulder is 90 degrees.
How to make your hands pointing in front of you?
With your arms at your sides, turn your palms towards your body and bend your elbows 90 degrees so your hands are pointing in front of you. Keep your elbows against your body and move your forearms towards your body. Imagine your body is a cabinet, your arms are the cabinet doors and you’re shutting the doors.
How many degrees of motion is normal for shoulder adduction?
A normal range of movement for shoulder adduction is 30 to 50 degrees depending on flexibility and body composition. If your chest or biceps are particularly muscular, it may be difficult to move your arms inward.
What are the bones of the shoulder?
Your shoulder joint is a complex system made up of five joints and three bones: 1 clavicle, or collar bone 2 scapula, your shoulder blade 3 humerus, which is the long bone in your upper arm
How many joints are there in the shoulder?
Your shoulder joint is a complex system made up of five joints and three bones: This system of joints and bones allows your shoulder to move in different directions. Each movement has a different range of motion. The ability of your shoulders to move in a normal range depends on the health of your:
