Shoulder Instability Or Dislocations

shoulder instability anatomy

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Shoulder is the most mobile joint of the body. This allows you to lift your arm, rotate your arm and lift your arm over your head. It’s possible to have a greater range of motion with less stability.

How

Shoulder instability

This happens when the humerus head (the upper arm bone) is forced out of the shoulder’s cavity. Usually this happens as a result of a sudden traumatic injury.

Once the shoulder is dislocated, the shoulder is vulnerable to repeat. When the shoulder is loose and slips several times, it’s called a chronic shoulder instability.

The shoulder is made of 3 bones : humerus (upper arm bone), scapula (shoulder blade) and clavicle (collarbone).

Dislocation shoulder

This may be partial, which means that the arm’s ball partially comes out from the cavity. This is called a subluxation. This can be complete which means that the arm’s ball comes out completely from the cavity.

Symptoms

Symptoms of chronic shoulder instability are :

  • Pain caused by the shoulder injury

  • Repeated shoulder’s dislocation

  • Repeated instance of the shoulder giving out

  • A persistent sensation of the shoulder that is loose, slipping out of the joint or hanging.

Diagnosis

Specific tests help assess shoulder instability (including general relaxation of ligaments). A doctor may prescribe imaging tests such as X-rays, CT Scan or MRI to confirm the diagnosis and identify other problems.

Treatment

First, chronic shoulder instability treated with nonsurgical options. If these options don’t relieve pain and instability, surgery may be needed.

Nonsurgical treatment

Generally, it often takes several months of nonsurgical treatment before success can be assessed. Nonsurgical treatments includes :

  • Activity modification

  • Non-steroidal anti-inflammatory medication

  • Physical therapy

Surgical treatment

Often, surgery is often required to repair torn or stretched ligaments so that they can maintain the shoulder joint in place.

Bankart lesions (tearing of the front labrum from the cavity) can be repaired surgically using suture anchors to reattach the ligaments to the bone.

Arthroscopy => Soft tissues of the shoulder can be repaired using tiny instruments and small incisions. It’s a procedure that is done the same day or outpatient. Arthroscopy is a minimally invasive surgery. The surgeon examines the inside of the shoulder with a small camera and performs the operation with special instruments.

Open surgery => These are patients who require open surgical intervention. This involves making a wider incision on the shoulder and performing the repair under direct visualization.

Rehabilitation

After surgery, the shoulder can be temporarily immobilized with a sling. When the sling is removed, it’s essential to do ligament rehabilitation exercises. These exercises improve the range of motion of the shoulder and avoid scarring during ligament healing. Thereafter, exercises for strengthening the shoulder will be added in the rehabilitation program.

Shoulder Impingement

shoulder impingement

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Impingement is the fact of having mechanical compression and/or tendon wear of the rotator cuff. Rotator cuff is composed of a serie of 4 muscles connected to the shoulder blade at the humeral head (upper part of the shoulder joint). The function of the rotator cuff is to maintain the humeral head within the glenoid (socket) during normal shoulder function and to participate in shoulder strength during activity. Normally, the rotator cuff glides gently between the inferior surface of the acromion, the bone at the point of the shoulder and the humeral head.

Causes

Any process that can interfere with rotator cuff being able to glide normally can cause impingement. The causes are :

  • Weakening

  • Degeneration of the tendon due to aging

  • Formation of the bone spurs

  • Inflammation of tissues on the space above the rotator cuff

  • Injury due to overuse

Overuse activities that can lead to impingement are most commonly seen in tennis players, pitchers and swimmers.

Diagnosis

shoulder impingement

Diagnosis can be made with the patient’s history and physical examination. Patients suffering impingement often complain of pain in the shoulder. This pain worsens with overhead activity and can be so strong that it causes an awakening during the night. Manipulation of the shoulder in a specific way by a doctor will usually reproduce the symptoms and confirm the diagnosis. X-rays are also useful for the evaluation of the presence of bone spurs and/or the narrowing of the subacromial space.

Treatment

The first thing to do is to eliminate identifiable causes or factor that contribute to the pain. This means temporarily avoiding activities like tennis, pitching or swimming. A non steroidal anti-inflammatory medication may also be recommended by your doctor. The treatment is based on exercises aimed at restoring flexibility and normal strength to the shoulder girdle, especially by strengthening the muscles of the rotator cuff and the muscles responsible for the normal movements of the scapula (shoulder blade). This program may be performed by a doctor, a certified athletic trainer or a qualified physiotherapist. Sometimes a cortisone injection may be helpful in the treatment.

Surgery

Surgery isn’t necessary in most case of shoulder impingement. But if the symptoms persist despite non-surgical treatment, surgical intervention may be beneficial. Surgery involves deriding or surgically removing, tissue that is irritating the rotator cuff. This can be done with open or arthroscopic technique. The result is favorable in about 90% of cases.

Masturbation And Sport

hand draw

I watched a Jamcore DZ’s video  and I learned good stuff.

My intention is to explain masturbation’s effect on a sport activity without being vulgar. Masturbation is a normal activity for some people and abnormal for others. In some religions, it’s a forbidden or ignoble activity but it’s an activity that most people do.

Type of person

type person

The open minded person

For this person, masturbation is a normal activity because it’s natural and give a good mood. It’s not something bad.

The guilty person

For this person, masturbation is an abnormal activity, ignoble but despite that, this person does it and still feels guilty after masturbation.

The obsessed person

For this person, masturbation is an obsessive activity. This person could masturbate every hour, every day.

The bored person

For this person, masturbation is an activity to kill boredom. He’s a person who has nothing to do in life or in the day and doesn’t know what to do, masturbation.

How the body reacts

chart masturbation dopamine orgasm prolactin testosterone

  1. The intensity of masturbation increases (black line)

  2. There is a release of hormones, it’s dopamine. Before masturbation, there is a first release of dopamine that cause sexual arousal and there are other dopamine release during masturbation (blue line)

  3. Sexual arousal during masturbation will start the process to have the explosion, this explosion is orgasm (red line).

  4. Once the orgasm has happened, there is a release of hormones, it’s prolactin. Prolactin causes the loss of interest to continue masturbation. You satisfied and you don’t want to continue to masturbate. In some situation, prolactin can make you feel guilty (green line).

Stop masturbation for 1-3 weeks

stop

chart masturbation dopamine orgasm prolactin testosterone

There is a black line in the middle of the chart. This is the line of testosterone. When you stop masturbation for 1-3 weeks, there is an increase in testosterone rate. But after 3 weeks, the testosterone rate returns to normal. You have to base on your normal testosterone rate to see if your testosterone is affected by anything.

It’s possible that during masturbation, the testosterone rate is below your normal testosterone rate. In this case, it’s another problem and it’s necessary to see your doctor for more details.

Most people think that masturbation makes you lose testosterone. So if masturbation makes you lose testosterone, it means that masturbation also make you lose muscles. The truth is that this myth is wrong.

Masturbation and gain muscle

anatomy muscle

The answer is « No » because the elements that influence muscle gain are training program, nutrition and rest/sleep. The only thing that masturbation does before or after a training session is the increase in heart rate.

Warning

Now that you have this information, it doesn’t mean that I encourage you to masturbation several times a day, every day. You do this when you want according to your desires but in moderation.

Techniques To Learn Quickly And Efficiently Based On Science (Part 2)

learn

I watched an Olivier Roland’s video  and I learned good stuff.

If you didn’t read the Part 1, click here .

Ok, this software used in the scientific study is not accessible for more than 80 % of the population but there are several software that can allow you to improve your intelligence like that used in the scientific study.

There is IQ Mindware. There is another one that is open source so free called Brain Workshop. These software are for people who really want to improve their intelligence because they are based on the principle of Dual n-back . It’s very difficult and it’s the only way to improve your intelligence.

The results of this scientific study showed that the maximum gains obtained with 20 minutes of training per day for 19 consecutive days. This is 10 % improvement with the 8 consecutive days of training and 44 % with 19 consecutive days of training.

Train your brain with IQ Mindware or Brain Workshop (I use this one) will allow you to improve your concentration and motivation. Everything you need to improve your ability to have successful projects.

Meditation

meditation

Meditation is excellent for improving your concentration. Before, I was often lost in my thoughts when I was doing a task and in the end, this task was done badly. Have you ever been lost in your thoughts when you were doing a task ?

Meditation is cool because you can do this in 5 minutes a day and you don’t need any equipment. You just need a little time and a quiet place. You see meditation is accessible to everyone and can be done by people of all religions or these who have no religion.

The goal of meditation is to train your concentration. That means to focus your attention on something specific. For example in bodybuilding, when you do the dumbbell curls, you fix your attention on your biceps. Meditation is a simple and effective way to become aware of your « parasitic thoughts ». These « parasitic thoughts » that make you no longer focused on your task and lost in your thoughts. When you realize that you’re lost in your thoughts, you can redirect your thoughts to be focus again on your task.

Scientific studies have discovered and are still discovering meditation’s benefits like an enormous reduction of stress, anxiety, anger, depression, immune system improvement, positive emotional improvement and a better attention. For people with hypertension, there is a decrease in blood pressure and an increase in longevity of 23 %. Scientists always find new benefits in meditation.

And

and

Meditation improves health AND also intelligence as ability to manage emotion, increase concentration, reduce attention problems, increase memory and visual processing capacity, improve learning ability and reduce your risk to multi-task. Doing multi-task ruin your productivity.

If you want to enjoy meditation’s benefits, you can start with a simple exercise without equipment today :

  • You sit comfortably in a quiet place. If you want you can sit in the lotus position but it’s not obligatory. You close your eyes and take 3 deep deep breaths to relax. Once you relaxed, you focus on your breathing. You focus on your inhalation and your exhalation and the goal is to concentrate as long as possible on your breathing

While you are going to think about your breathing, full of thoughts will come constantly and it’s normal. It’s destabilizing but there is a technique for your mind to be less distracted. The technique is to count the number of your inhalation and exhalation.

  • When you inhale, you count « 1 » in your head (don’t speak) and when you exhale, you count « 1 » then when you inhale, you count « 2 » and when you exhale, you count « 2 ». You do it from 1 to 10. When you’re 10, you count upside down from 10 to 0. When you realize that you’re lost in your thoughts and you’ve lost count of the number of breathing, you start again at « 0 ». You don’t give up until you’ve been able to count from 0 to 10 and 10 to 0 without interruption at least once.

You’ll see that many thoughts will come because it’s absolutely impossible to think of nothing. Don’t worry, it’s normal. As soon as you realize that you’re lost in your thoughts, come back to focus on your breathing without feeling any particular guilt.

Do this simple meditation 5 minutes a day will give you many benefits that I quoted in this article.
