🔎 Musculoskeletal Diseases – Definition and Explanations


The musculoskeletal problems (TMS or LATR, repetitive motion joint injuries, in Quebec) covers many soft tissue pathologies (muscles, tendons, nerves). Here it is disease (A disease is a change in the functions or health of a living organism, animal…) The most common professional in France and the world developed nations (Advanced market economy countries (DEMC) are countries that …) yes, yeshour (Time is the unit of measure 🙂 current.

Various pathologies

These disorders are not a specific disease, but a heterogeneous group of different specific conditions.

List of relevant pathologies

Acute bursa bursa (elbow)

  • For the wrist (The wrist is the region of the upper limb located between the hand and the forearm,…)the hand (The handshake effect is organ…) and fingers:
    • Tendonitis (Tendinitis is a painful inflammation of a tendon and is part of disorders…)
    • Tenosynovitis (Tenosynovitis is tendonitis characterized by inflammation of the tendon and…)
    • Syndrome (A syndrome is a collection of clinical signs and symptoms to which a patient is susceptible…) carpal tunnel
    • DeQuervain syndrome
    • Guyon compartment syndrome
  • For elbow (In front of this joint is the “elbow flexion” area. This…):
    • Epicondylitis
    • Epitrocleitis
    • bursitis
  • For the shoulder:
    • Rotator cuff tendinopathy

Warning signs

Warning signs that make it possible to fear MSD are:

  • Local and persistent muscle fatigue, resulting in:
    • Body aches during exercise
    • Difficulty achieving previously achieved efforts
  • Tingling or numbness in nerve damage (carpal tunnel, etc.)
  • A bent finger, when the tendon is damaged (Dupuytren’s, etc.)

The most famous disease is carpal tunnel syndrome. the nerve (In neuroanatomy, within the nervous system, peripheral and central, nerve…) the carpal tunnel, which controls the first three fingers of the hand, is compressed. This causes pain and tingling at night, and then discomfort and awkwardness at work. Each year (A year is a unit of time that represents the time between two occurrences of a related event…), there are 2000 cases of carpal tunnel syndrome in France, whose occupational origin is recognized in 130,000 operations. There is an important understatement phenomenon.

Understanding MSDs to prevent them

MSDs are not inevitable in business. It is possible to prevent their appearance with ergonomic intervention. An ergonomist can situation (In geography, situation is a concept of space that allows for the relative location of a place…) from the work put in day (A day or day is the interval between sunrise and sunset; it…) risk factors and factors determining the onset of MSDs at work.

Risk factors

Risk factors for MSD include: biomechanical factors, psychosocial factors (stress), as well as disease characteristics.individual (WikiDictionary is a free and open source dictionary project similar to Wikipedia (both…) . This last one risk factor (In risk management, a risk factor is a source of risk classified as…) the individual represents a fairly low risk.

Biomechanical factors

  • “repetition” of gestures
  • excessive effort
  • work static (The word static can designate or qualify that which is associated with the absence of movement. It…) kept low time (Time, by man…
  • extreme joint positions.

the cold (Cold is the opposite of heat associated with low temperatures.) and tremors can aggravate these events.

In 2003, 24.7% of men who manually operated loads for more than 20 hours were at increased risk of MSDs, compared to only 14.3% of women.

However, women are more exposed to the risk of becoming a victim of MSD by working with visual restrictions (screen) for more than 20 hours. height (Height has several meanings depending on the subject area.) 58% against only 36.7% for men.


Psychosocial risks

  • Lack of autonomy
  • demand level,
  • social support (work team),
  • a feeling of not being recognized at one’s fair value,
  • and so on

the stress (Stress (“constraint” in English) or general syndrome…) Cheek (The cheek is the part of the face that covers the oral cavity…) It plays an important role in the onset of MSDs, as it can cause muscle pain, a fall speed (We notice 🙂 repair of muscle tissue, appearance of edema, inflammation of tendons, etc. There are other long-term effects of stress as well heart attack (A heart attack is defined by the sudden and massive death of cells (necrosis…), ulcers, constipation, thickening and blockage of arteries, etc. Stress occurs when people do not have the opportunity to act in a situation that they consider aggressive. If they can change it environment (Environment is everything that surrounds us. All natural elements and…)this will have a beneficial effect on their situation health (Health is a state of complete physical, mental and social well-being and…).

Determinants of the appearance of MSDs

The reasons for the appearance of MSDs should be sought not only in the risk factors that facilitate the appearance of disorders, but in the determinants that affect the work situation. Thus we will find:

  • L’organization (It is an organization) from production
  • organization of work
  • Equipment design
  • Product design
  • Tools
  • Gestures (in terms of instructions and procedure)
  • Talent management, career development, versatility
  • Work environment
  • Organizational dependencies
  • Salary methods

Change business situations to take action

Actions can be taken to eliminate MSD risks in the workplace using three types of measures:

  • Technical measures: should be related to direct risk factors (biomechanical), which are efforts, extreme angular positions, repetition of gestures.
    • Adaptation of workstation after detailed analysisactivity (The term activity can refer to a profession.) operators
    • Reduction of working masses
    • Reducing excessive repetitive tasks
    • Adding a physical aid (anti-rotation arm for screwdrivers, …)
    • Usage materials (A material is a material of natural or artificial origin formed by man…) absorb vibrations (tool holders, etc.)
    • If possible, replace vibrating tools with non-vibrating tools (wrench). shock (When two entities violently interact, we say that there is a shock, or…) replaced by an electric screwdriver,…)
  • Organizational measures
    • Changing operators at the station to limit risk (less stress per operator).Attention masked effects can lead to the appearance of an “epidemic” with this technique. Few operators suffer from similar pathologies due to exposure to risk factors, even limited, but the effects can be cumulative.
    • Work organization to limit repetitive tasks (just-in-time production)
    • Information to operators about risky postures and their consequences, encouraging them to correct their posture, supporting technical changes at workstations.
    • When there are extreme demands (e.g., slaughterhouses), prepare operators by stretching and warming up before starting the task.Attention this is not a solution size prevention (Prevention is an attitude and/or set of actions to be taken to prevent…) as long as the extreme demands exceed the physiological capacity of the operators.
    • Take breaks during work to allow the body to recover
    • Encourage operators to take compensatory actions (extension, etc.)
  • L’to learn (Learning is the acquisition of know-how, i.e. the process…) correct gestures and movements (ergomotricity) to lift and transportation (Transportation is the act of moving something or someone from one place to another, most often…) loads, e.g.
    • by correcting spine (The spine or vertebral column is a collection of articulated bones called….)
    • Overlapping the centers weight (Gravity is one of the four fundamental interactions of physics.) (Man – cargo).
    • By providing stable supports and research (Scientific research is primarily… balance.
    • By requiring the legs (the strongest segments of the body).
    • By pointing the feet in the direction walk (A walk (the pleonasm walk is also often used) is a…) eliminating all rotations of the body.

But in no case can we apply ready-made solutions. Every business situation is unique and needs to be called upon ergonomic and ergomotor analysis of the human-work duo to ensure that proper preventive measures are taken.

Legislation in France: adopted to fill (Cargo means what it really is…) in occupational disease

Occupational disease coverage is subject to strict medical and administrative criteria. The blackboard recognition system relieves the employee of the obligation to provide proof of repeated actions in the workplace.

Prevention in France

From May 11 to 15, 2009, health insurance presented its second edition National Musculoskeletal Disorders Awareness Week (TMS). The theme of 2009 is ” commitment of professional sectors “.
