What are the Consequences of Poor Manual Handling?

Activities that involve lifting, carrying, pushing, pulling, and other related manoeuvres are often inevitable at work. Machines can only do so much; sometimes we just have to utilise our own strength.

However, if not done properly, manual handling can lead to the gradual deterioration of both physical and mental health. Receiving training in proper manual handling techniques is essential. Our bodies have amazing capabilities, but also great limitations. Like machines, they’re going to develop faults and break down after long-term misuse. And when we’re worn down physically, we tend to get worn down mentally too.


Consequences of Poor Manual Handling

Consequences can be split into three main areas: short term and superficial injuries, long term injuries and mental health issues.

1. Short-term and/or superficial injuries

For example: cuts, bruises, sprains, tears, small fractures, muscle strain, etc. Usually caused by sudden and small unexpected accidents, e.g. losing grip and dropping a load, lifting an excessively heavy load at an awkward angle, or falling while carrying a load.

2. Long-term injuries

This mainly involves damage to the musculoskeletal system of the body, including muscles, tendons, bones, joints, ligaments, nerves, and blood vessels –usually caused by long-term, gradual wear-and-tear as a result of repetitive strenuous activities. These are known as musculoskeletal disorders.

3. Mental health issues

For example: long-term stress and anxiety, and depression. This is usually a negative side effect of dealing with long-term injuries that have disabling and difficult-to-manage symptoms.

Physical ailments are more readily recognised than mental health issues related to poor manual handling, but we must not overlook the fact that long-term injuries can have a serious knock-on effect: they can lead to poor mental health due to the stress and anxiety triggered by long-term physical issues.

This is why knowing how to prevent the development of both physical and mental ailments caused by bad manual handling practices is essential.

Let’s take a look at two of the more major negative consequences – musculoskeletal disorders and depression – in more detail.


Musculoskeletal Disorders

You have likely experienced or know someone who has experienced problems in the neck, upper/lower limb, or upper/lower back, and so have first-hand knowledge of how debilitating they can be. Long-term disorders and injuries in these areas are defined as musculoskeletal disorders, and lower back issues are the most common.

The majority of work-related musculoskeletal disorders are caused by poor manual handling practices, particularly tasks that involve:

  • Heavy or awkward loads (loads may be animate e.g. people or animals, or inanimate e.g. boxes and tools).
  • Twisting, turning, and bending the back, neck, or whole torso.
  • Hard-to-reach areas that require stretching.
  • Working in a cramped environment with unstable flooring.

You might feel like your body is tough enough to take the strain of having to occasionally adopt awkward positions, but no one’s body is built for misuse: over time it will inevitably wear down.

According to the HSE:

  • Manual handling is the main work activity that causes back disorders.
  • The total number of recorded work-related musculoskeletal disorders (WRMSDs) in 2016/2017 was an estimated 507,000.
  • An estimated 8.9 million working days were lost due to WRMSDs.
  • Approximately 40% of musculoskeletal disorders affect the back and 45% affect upper limbs.
  • Examples of industries that have higher rates of WRMSDs include agriculture, construction, transportation and storage, and health and social work.

These statistics reveal the pervasiveness of work-related musculoskeletal disorders, particularly in relation to manual handling: the industries with higher ratings are those that require a significant amount of manual handling.

But they also reveal how enduring they are: 159,000 were new cases, meaning around 348,000 were existing cases that had yet to fully recover.


Symptoms of Musculoskeletal Disorders

Musculoskeletal disorders have numerous symptoms that range from mildly uncomfortable to severely disabling, including:

  • Localised or widespread pain.
  • Limited movement.
  • Dull aches.
  • Swelling.

  • Aching or stiffness of the whole body.
  • The sensation of pulled or overworked muscles.
  • Fatigue.
  • Disturbed sleep.
  • Twitching or ‘burning’ muscles.

Many of these symptoms are difficult to manage, and make day-to-day tasks a challenge – particularly if the person has to limit or stop work activities altogether. It can completely uproot their life, especially because musculoskeletal disorders are typically long-term ailments and have slow and laborious recovery processes.

The good news is that musculoskeletal disorders take a long time to develop: repeated strain of the back over prolonged periods is what will put you at risk, not the occasional overestimation of your strength.

But the bad news is that, because it takes repeated strain, you may not notice the damage you’re doing to your body until it’s too late. Thus, preventing risk by engaging in safe manual handling practices is a necessity.


Depression

The negative mental health effects that may stem from injuries relating to manual handling must not be overlooked. Recent research has revealed that many workers who suffer from musculoskeletal disorders end up requiring treatment for depression.

Researchers interviewed workers with musculoskeletal disorders at one, six, and twelve months following their injury, and discovered that almost 30% were receiving treatment for depression after twelve months.

Depression comes with a variety of extremely debilitating symptoms that, on top of the musculoskeletal disorder itself, would likely slow the person’s life down to a crawl or to a complete halt.


Symptoms of depression may include:

  • Continuous low mood.
  • Hopelessness.
  • Lack of physical and mental energy.
  • Disturbed sleep.
  • Feeling helpless.
  • Changes in weight or appetite (either decreased or increased).
  • Feelings of uselessness.
  • Low self-esteem.

  • Feeling guilt-ridden.
  • High levels of anxiety.
  • Continuous thoughts of worry.
  • High levels of irritability and intolerance.
  • A severe lack of motivation or interest.
  • Difficulty making decisions.
  • Lack of enjoyment in life.
  • Thoughts or acts of harming oneself.
  • Suicidal thoughts.

Depression varies from person to person, particularly depending on what the main cause is. But in the case of musculoskeletal disorders prompted by manual handling activities, sufferers will have a great deal of overlap in terms of what type of symptoms and negative thoughts they experience. For example:

  • Having hopeless thoughts that their condition will never get better.
  • Thoughts of worry: thinking that everything they do will make it worse.

  • Feeling useless as a result of their lack of mobility (particularly if they can’t carry out manual handling activities anymore and have to change job roles).
  • Feeling like they can no longer get enjoyment out of life because they can’t engage in activities that require physical activity, e.g. sports.

The extensive lists of debilitating symptoms that come with musculoskeletal disorders and depression clearly demonstrate how poor manual handling can have serious long-term effects that stem from one another, and how important it is to make a conscious effort to adopt proper manual handling techniques.
