If you find you have persistent discomfort in your back, neck, or shoulders, we welcome you to visit us. Physiotherapy can be an effective tool for pain relief.

The changing professional environment has brought about many challenges, and among them is dealing with the ramifications of a predominantly office-based environment.

Today, most people spend a good part of their day sitting down. Whether it’s working in an office, sitting in a classroom, or how we spend our recreational time, we (people) have never spent more time on our butts.

This isn’t doing your posture any favours- ditto for your back, neck, and shoulders.

Sitting All Day Leads to Slouching; Slouching Leads to Back, Neck, and Shoulder Pain

We know that it’s popular these days for articles about posture to emphasize the importance of proper posture- especially when it comes to slouching. However, as we are physiotherapists, it’s our job ;)

Here’s the thing: we can help relieve your back and neck pain through physiotherapy, but most of our patients can lessen their time and financial costs in physiotherapy by making smart investments into improving their posture.

If You’re Visiting Us, It Means You’re in Pain. For Many People, This Pain Can Be Avoided by Improved Posture When Sitting.

We don’t mean forcing yourself to sit straight as a board. Contrary to popular belief, your spine isn’t supposed to be perfectly straight– it’s normal and natural for your spine to have curves (three, in fact).

However, when we slouch, we alter this curvature and place stress on muscles and parts of the spine that aren’t properly equipped to deal with those stresses. As many of us unfortunately know first hand, slouching too much leads to back, neck, and shoulder pain.

How Slouching Influences Back Pain

It seems counterintuitive that sitting all day can cause pain in our lower back, but for millions of Canadians, this is exactly what happens.

Why?

Lumbar Degenerative Disc Disease

Studies dating back to 1996 have demonstrated that slouching while sitting or standing plays a role in progressive disc degeneration.

More commonly referred to as lumbar degenerative disc disease (DDD), the causes are multifactorial- while slouching on its own is unlikely to cause DDD, it can be a significant contributing factor.

Symptoms of DDD may be familiar to some:

  • A consistent “low-grade” pain that flares up when performing certain motions or activities
  • Pain that shoots down the leg (sciatica)
  • Relief of pain when lying down in a reclining position
  • Relief of pain when knees are elevated

Being seated loads your lumbar spinal discs by more than 3x compared to standing. Poor posture exacerbates these stresses.

Iliolumbar Ligament Strain

Slouching for prolonged periods of time loads and strains the iliolumbar ligaments.

A strained Iliolumbar ligament can make it uncomfortable to sit (regardless of position), kneel, or to stand up. Pain can be ongoing, intermittent, or episodic.

In the above linked article, they hypothesize that consistent microtrauma to the Iliolumbar ligament (such as when slouching) is one of the primary causes of lower back pain, and they have good evidence to reinforce that sentiment.

How Slouching Influences Neck Pain

Many of the same stresses that slouching places on your lumbar spine are carried upward to your neck.

Your spine has three natural curves:

  • Cervical (upper spine and neck)
  • Thoracic (middle spine)
  • Lumbar (lower spine)

In the prior section about back pain, we focused primarily on the lumbar spine. In this section, we’re concerned about the cervical part of the spine.

Slouching when sitting has two effects on upper spinal alignment:

  1. First, we place significantly more load on our neck when our heads creep forward. Every 2.5 cm of forward positioning adds approximately 3.5kg of additional load to the neck.
  2. Increased load on the cervical spine contributes to spinal disc compression, which can have lasting and significant ramifications.

Slouching Increases the Perceived Weight of Your Head

You may not realize it, but your neck and upper spine have to keep your head upright all day and night. It’s safe to say that a fair amount of stress is placed on them consistently, as they bear the weight of your noggin’ until you lie down.

When you start to huddle forwards – which is exactly what we do when slouching – you change the physical dynamic between your head, neck, and cervical spine.

Every 2.5 cm of forward positioning adds approximately 3.5kg of additional load to the neck.

This additional load fatigues your shoulder and upper back muscles, causing muscular imbalances, and also contributes to spinal disc compression.

Spinal Disc Compression

A compressed disc can impinge nerves, restrict movement, and cause significant pain. In the case where nerves are impinged, pain may radiate into the arms and lower back.

Disc compression can be a result of whiplash, accident, or sporting injury. Slouching is unlikely to cause disc compression on its own, but it can exacerbate other contributing factors and aggravate the disc post-injury.

How Slouching Influences Shoulder Pain

Simply put: a slouching position creates an environment where your shoulder blades are no longer in proper alignment.

Known as the scapulae, they drift apart to the sides of the rib cage when sitting slouched. Over time, this can leads to weakness of the posterior shoulder muscles, tightness of the anterior shoulder muscles (the “pecs”), and a multitude of conditions that can include impinged nerves, restriction in range of motion, and rotator cuff dysfunctions.

Shoulder Impingement

This study published in Manual Therapy found that your shoulder range of motion is significantly greater when exercising proper posture. This is because your shoulders are in better alignment, allowing the rotator cuff to properly function; when your shoulders are misaligned, they can pinch against the acromion – the bony part of the scapula (shoulder blade).

Another name for a pinched rotator cuff? Shoulder impingement.

Symptoms of shoulder impingement include:

  • Difficulty raising arms above your head
  • Difficulty reaching behind your back
  • Pain when twisting or extending your arm
  • Weakness in the affected shoulder extending down into the arm

Don’t be a Pain in the Neck – Be Proactive With Your Posture!

Proper posture is more an exercise in habit than it is anything else. Once you form new habits, it becomes much easier to consistently exercise good posture.

Here’s a handy visual that helps illustrate proper posture:

Some Proper Posture Pointers

  • Opt for a chair that has a backrest designed to supplement your natural curvature. This can help you maintain proper posture.
  • Adjust your workstation so your monitors are about 30” away from you, and position them so the top of the monitor is level with the top of your forehead.
  • If possible, switch to a standing desk. Many people find it easier to maintain proper posture when standing vs. sitting.
