I hope that everybody can see and hear.

Now the slide.

Good. Thanks for the answer.

So welcome to the first force edition of empirical research methods and medical engineering.

This topic is research questions study designs and procedures.

And this is the agenda for today.

So first we're going to talk about research topics, problems, questions and hypotheses.

How to ask the right questions.

Then we're going to get into study design.

How you plan to get answers.

And then we are talking about the study procedure.

How to collect data to get the answers.

So how to ask the right question.

So from topic to design, first you start off with the research topic.

Specified more into research problem.

Get to the research question, formulate, I have positives and make a study design that is able to answer this hypothesis.

So the first step is the research topic.

It designates an object of research and it is also differentiation from other topics.

It also represents the state of the art of research.

Examples are assistive variable robots, pseudo-putricular rehabilitation robots, capsule robots.

So it's quite specific already.

So not just medicine.

But it doesn't ask a question yet or anything like it.

It just makes it like it gives you a topic.

Then you get to the research problem.

A research problem describes which findings on which aspects of the research are to be gained with on which theoretical empirical or methodological basis.

So the research problem is differentiated into several research hypothesis and or research questions.

So you can have several hypothesis and several questions in one problem.

Basically.

Examples are, in some situations, low loads have to be lifted and it's not possible to have a machine to do it.

For example, in caves and war zones, etc.

So wearable robots may be an alternative in such situations.

Another example is, the older you are, the more prone you are to strokes and the less you tend to trust technology, including robots.

However, technology specifically variable robots can be of benefit in rehabilitation.

And now you get to the research question.

Research question is based on the state of research to date and is aimed primarily at research gaps.

It determines whether regularities exist, what their nature is, in which direction they point, how strong they are, and how they come about, etc.

Exploration of an issue and generation of new series.

If there's research question and examples are, can users lift more than more when wearing an exoskeleton than without one?

What is the maximum expected increase in lifting capacity when wearing an exoskeleton?

Can users conduct precision maneuvers in nervous spaces wearing an exoskeleton?

And what are real life pain points of users of exoskeletons?

And then from these research questions, you can have hypothesis.

These are preliminary contract answers that you should give to the questions are called hypothesis.

Derived from established theories and or well established empirical findings.

Hypothesis testing is used to test in advance existing series.

So if you have an theory already, you form a later hypothesis in order to prove or disprove it.

Conjunctures and conjunctures are conjunctures until scientific evidence is available.

A hypothesis may postulate the existence, direction and strengths of a particular effect.

And a complementary null hypothesis can be formulated which negates the postulated effect.
