Correct posture and remote work effects

Rossano Zangerolami, Osteopath

Who would have thought that 2020 would hold us such a difficult challenge! It is a year of upheaval both at the work and social level. This epidemic has imposed social distancing and consequently remote work has been introduced in an urgent and widespread way. Remote work has allowed many workers to continue their business from home, so it was an excellent opportunity to find work continuity.

However, it arrived like a tsunami, so suddenly, and without having the appropriate time to study and prepare the new workstations and the ergonomics of the home furniture.

Remote work means ‘agile work’, but certainly not for our back and the increase in musculoskeletal disorders (MSD) during this pandemic, especially at the cervical level, is proof of this.

Cervicalgia

It is the pain that we feel in the neck, along the cervical tract and it is one of the most common pains especially by video terminals. Knowing the reason that triggers the disorder could help us to adopt behaviors and movements to avoid it and correct it.

The origin of pain is multifactorial and mainly determined by two types of factors:

– physical: generated by prolonged time spent in inadequate position / posture, lack of adequate physical exercise, repeated hand movements.

– psychosocial: generated by stress, such as the conflict between work and private life, for problems in family management (especially for those who have responsibilities for the care of minors or elderly people), a hostile work environment and monotonous tasks.

Posture

Incorrect postures risk causing latent muscle or joint disorders to emerge or cause new ones in the short or long term.

Cervical pain in particular is significantly associated with mouse use for more than 2 hours, computer use for more than 6 hours, or in stressful positions with increased forward neck / head flexion for more than 1 hour. without regular breaks.

Unfortunately we find ourselves working with notebooks that force us to look continuously with the head in front of us, with chairs taken from the dining table that do not support the back, often remaining with the curvature of the lumbar spine reversed.

This problem does not only concern workers, but also students! Many of them find themselves following the lessons from the tablet or even worse from the mobile phones, remaining for hours in incorrect postures that cause joint and visual overload.

Tensions, particularly in the muscles of the cervical tract, generate contractures that over time will create localized pain at the base of the occiput, trapezius muscle or subscapularis, also giving rise to major tension headache episodes.

Remedies

Working in remote mode is possible, but to reduce the risks it is recommended to strengthen the neck and shoulder muscles with appropriate exercises. Then you need to use desktop stands for PCs: the monitor must always be positioned at eye level.

If you use a laptop, use books to lift it and an external keyboard to maintain the correct position of the elbows. It is important, in fact, to avoid looking down so as not to strain the cervical. It is also essential to sit with lumbar support. Use an ergonomic chair, if possible, so that it can be adjusted according to the characteristics of the subject, in some cases the use of an inflatable pillow may be useful. Usage time should also be monitored. It is advisable to take a break every 30 minutes to rest the spine and reactivate the muscles.

To reactivate the latter, just:

  • take a few steps
  • stretch your back
  • perform simple shoulder circles to stretch the neck muscles

A fundamental advice in this period, where even the gyms are closed, is to stay active and avoid a sedentary lifestyle, therefore, if possible, jogging or aerobic exercise, but simple walks are also fine to avoid loss of muscle tone.

Osteopathic Treatment

The intervention of an Osteopath, based on a postural analysis and a thorough medical history, is the winning weapon to eliminate pain and restore the body to its original balance.

Proceeding with a personalized treatment, the professional will be able, through manipulations (articular and / or visceral), craniosacral techniques, stretching and muscle strengthening, to eliminate the origin of body decompensation.

Treatment for neck pain

1 – To promote relaxation after an intense day of work, apply a few drops of Sinergia S.A. to the temples and under the nostrils. , a balsamic blend of essential oils that helps the respiratory tract and the re-oxygenation of the skin.

2- Perform a massage in the affected area with a few drops of Olio Strongful which acts on muscle stiffness with a decontracting and anti-fatigue action

3- Then apply the Balsamo BeC, a skilful combination of essential oils with anti-inflammatory properties, including Savory and Wintergreen, and calming, such as Chamomile and Lavender, which make it able to effectively counteract local irritations, giving immediate relief.
You can repeat the treatment twice a day.

Listen to your body and always take care of yourself!

Cyclooxygenase, lipoxygenase and the inflammatory process

Cyclooxygenase and lipooxygenase are the two families of enzymes that are commonly involved in the inflammatory process, through a complex of reactions which is called arachidonic acid cascade. This complex of reactions develops as follows: a first enzyme, a phospholipase cleaves the phospholipids of biological membranes, releasing arachidonic acid, a polyunsaturated fatty acid with 20 carbon atoms (eicosa-5Z,8Z,11Z,14Z-tetraenoic acid ; C20:4; ω-6). The arachidonic acid is then transformed by two parallel enzymatic pathways, that is, by two families of enzymes: the cyclooxygenase which transforms it into prostaglandins and thromboxanes and the lipooxygenase which transforms it into hydroperoxides which in turn transform into leukotrienes .
There are two cyclooxygenase isoforms indicated with type 1 and type 2, briefly COX-1 and COX-2. COX-1 is the enzyme present in most cells (except red blood cells), and is constitutive, that is, it is always present. COX-2 is an inducible cyclooxygenase isoform: it is constitutively present in some organs such as brain, liver, kidney, stomach, heart and vascular system, while it can be induced (i.e. developed if necessary) following inflammatory stimuli on the skin, white blood cells and muscles.
There are various types of lipooxygenase that lead to different products, the most important in the inflammatory process is 5-lipooxygenase, 5-LOX.

Prostaglandins, Thromboxanes, and Leukotrienes

Prostaglandins, Thromboxanes, and Leukotrienes are chemical messengers or mediators, that is, molecules that bring a message to specific cells and activate or deactivate metabolic responses in these cells. They, therefore, have a function similar to hormones, only that, unlike what hormones do, the chemical message is carried only at a short distance, that is, only to the cells that are in the vicinity of the place where the mediators were produced. There are different prostaglandins, different thromboxanes and different leukotrienes that carry specific messages. In many cases these act as mediators of the inflammatory process , therefore they trigger all the events that are involved in inflammation:
– vasodilation with consequent blood supply (redness),
– increased capillary permeability with consequent fluid exudation (swelling or edema),
– stimulation of nociceptive nerve signals (pain),
– on-site recall of immune system cells that attack a possible invader (chemotactic action)
– activation of the biosynthesis of fibrous tissue to strengthen or repair the affected part (even if there is no need)
– generations of free radicals that can chemically destroy an invader (but also damage our tissues, i.e. they just “shoot in the middle”).
Prostaglandins and thromboxanes, however, also play important physiological roles in normal conditions, i.e. in the absence of inflammation. For example, they regulate the secretion of mucus that protects the walls of the stomach, they regulate the biosynthesis of cartilages and synovial fluid in the joints, they regulate vasodilation, hence the correct flow of blood in the various local districts, and more.

Triglycerides

Triglycerides are the main components of most oils and fats. These are heavy, non-volatile and little polar molecules, insoluble in water, made up of glycerol (or glycerin) esterified with three molecules of fatty acids: therefore, it is a tri-ester of glycerin, from which the name derives. Each fatty acid contains 8 to 22 carbon atoms (commonly 16 to 18) and can be saturated, mono-unsaturated or poly-unsaturated. The size of the fatty acids and their saturation determines the physical and sensorial properties of the triglycerides, which can appear as oils (liquids at room temperature) or fats (solid or semi-solid) and can have greater or less greasiness and smoothness on the skin. Unsaturated triglycerides or with shorter fatty acids are more fluid and have greater flowability.

Fatty acids (saturated, mono-unsaturated and poly-unsaturated)

The name fatty acids is commonly used to indicate those organic acids that are found in the composition of lipids, that is, in animal and vegetable oils and fats, both in the free form and in the form of esters with glycerol (e.g. in triglycerides), or they are esterified with “fatty” alcohols, that is, long chain alcohols, to form waxes. Fatty acids are carboxylic acids (formula R-COOH) which have a long carbon chain (R), unlike common organic acids such as acetic acid and propionic acid, which have 2 or 3 carbon atoms in total, respectively. Fatty acids are defined as saturatedif they do not have double carbon-carbon bonds, (called “unsaturations”), they are defined mono-unsaturated if they have only one, they are defined mono-unsaturatedpoly-unsaturated if they have two or more double bonds (see figure). The term omega-3 (ω-3) or omega-6 (ω-3), refers to the position of the first double bond starting from the bottom of the chain of carbon atoms: if the first double bond is encountered after 3 carbon atoms the fatty acid is classified as omega-3 , if after six carbon atoms omega-6 , as shown in the figure. The most common saturated fatty acids are palmitic acid (16 carbon atoms and no double bond, C16: 0) and stearic acid (18 carbon atoms, 18: 0), the most common mono-unsaturated is the oleic acid, typical of olive oil (18 carbon atoms and 1 double bond in position 9, C18: 1; ω-9), while the most common poly-unsaturated are linoleic acid and linolenic acid, progenitors respectively omega-6 and omega-3 (see figure).

Terpenes and terpenoids

Terpenes or terpenoids are a large family of natural molecules, typically containing 10 to 30 carbon atoms, which are biosynthesized from a common “brick”, isopentenyl pyrophosphate (IPP), containing 5 carbon atoms (see figure). The discovery that the repetitive brick consists of 5 carbon atoms is relatively recent, while it was once assumed that the entire family was created by repeating a brick of 10 carbon atoms, which was called “terpene”. Therefore, the molecules with 10 carbon atoms (such as limonene, see figure) were called mono-terpenes, i.e. composed of a single brick, diterpenes those with 20 carbon atoms (e.g. the cafestol that gives the aroma to the coffee), triterpenes those with 30 carbon atoms (e.g. beta-carotene). Since molecules made from 15 carbon atoms were also found (such as bisabolol), it was thought they contained a terpene and a half, and were called sesquiterpenes (from the Latin semis = half + atque = and). Today it is known that the repetitive unit is composed of 5 carbon atoms, therefore it is easy to understand how mono-terpenes contain two (see figure), sesquiterpenes three, diterpenes four, triterpenes six.
