Keywords

💡Back Pain

Back pain refers to discomfort or pain in the back that can be acute or chronic. In the context of the video, it is a common complaint among working individuals, particularly in farming where various types of machinery are used. The video emphasizes the prevalence of back pain due to the physical demands and vibrations experienced while operating agricultural machinery.

💡Agricultural Machinery

Agricultural machinery encompasses a range of equipment used in farming for tasks such as planting, harvesting, and managing crops. The script discusses how these machines can expose operators to high levels of vibration, which is a contributing factor to back pain. Examples include combines, tractors, skid-steers, and ATVs, each with varying levels of vibration.

💡Vibration

Vibration is the mechanical phenomenon where an object oscillates back and forth around an equilibrium point. In the video, it is identified as a significant factor that can increase the risk of experiencing back pain when using vibrating equipment on a farm. The daily dose of vibration is related to both the strength and duration of exposure, which can lead to physical fatigue and strain on the back.

💡Combines

Combines are large agricultural machines used for harvesting grain crops. The video mentions that combines have lower vibration levels and more consistent operation compared to other types of machinery. This suggests that the design of combines may be less strenuous on the operator's back, reducing the risk of back pain.

💡Tractor

A tractor is a powerful vehicle specifically designed to perform various agricultural tasks, including plowing, towing, and lifting.

- Back pain and low back pain in particular

is really the most common complaint of working people

worldwide, across virtually all industries.

So, it's an enormous problem

and farming is interesting

because people use all types of machinery

to get done what needs to happen on the farm.

Vibrating equipment can place demands on the back

that can increase one's chances

of experiencing back pain down the road.

So, it's not surprising, but we observed

that agricultural machinery does expose people

to relatively high levels of vibration.

We did find some interesting differences

between machine types.

We found that combines were a little bit lower

in vibration level and also more consistent.

Whereas something like a tractor

or maybe a skid-steer or an ATV

may be used for all kinds of different things

on the farm, and so we see a lot more variability

in the vibration levels on those pieces of equipment.

I will say that manufacturers have come a long way

over the last few decades in terms of

equipment design and seat design,

especially seat suspension systems.

There are new seats that act a lot like

noise cancelling headphones that sense the incoming vibration

and emit a cancelling vibration, which is really cool.

The daily dose of vibration is related

both to how strong a vibration is

but also the duration of use.

Operating vibrating equipment is fatiguing,

physically fatiguing for the back.

I mean, you're shaking around

and your body is constantly responding to that,

trying to stabilize your spine.

So one of the things that ergonomists

have discussed for a long time

is that as you get out of machine,

after you've been in it for a period of time,

just walk around a little bit,

take a little break before you start lifting

other heavy stuff because that,

you don't need to be imposing other physical demands

on your back after you've been

in a vibration environment for a long time.
