Lab Report Analysis Essay
Introduction with Thesis Statement
- These Lab Reports discuss the topic of sleep position vs sleep quality.
- There are 3 Lab reports that all try to achieve similar findings about sleep quality using good research. However the different conditions make each lab report distinct.
Background info: https://nsuworks.nova.edu/cgi/viewcontent.cgi?article=1134&context=ijahsp
This survey had the purpose of investigating the association between sleep position, sleep quality, age, gender, and the prevalence of pain, stiffness, or aching in the neck, arm, between the scapulae, and headaches to find that participants sleeping in an upright position were more likely to experience the symptoms of interest compared to subjects that slept in other positions.

This experiment had the purpose of using flexible wearable sensors to monitor the impact of sleeping positions and turning frequency, and studying sleep patterns, to find that the most influential factors were the preference of sleeping position and how often the participant turned.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8631621/pdf/pone.0260582.pdf
This experiment had the purpose of comparing sleep posture and sleep quality in participants with or without specific spinal symptoms to find that participants in the symptomatic groups had reported a lower sleep quality than the Control group.
Lab Report 1: Sleep Position, Age, Gender, Sleep Quality, and Waking Cervico-Thoracic Symptoms
Lab Report 2: The Relationship between Sleeping Position and Sleep Quality: A Flexible Sensor-Based Study
Lab Report 3: Examining relationships between sleep posture, waking spinal symptoms and quality of sleep: A cross sectional study
Title:
Lab Report 1:
- This title includes all the variables used in the lab report.
- This title just gives a list of these variables without really defining any relationship between them.
- It does not really give the reader any clues about what the lab report will be about.
Lab Report 2:
- This title also includes the variables that will be used in the lab report.
- However, instead of just listing these variables like in lab report 1, a relationship is described between two of them.
- This title also shows what this report could look like by including some information about the study, a flexible sensor-based study.
Lab Report 3:
- This title also includes the variables used in the lab report, like lab report 1 and 2.
- It also shows that there is some kind of relationship between the variables, but it is not clear between which variables, unlike lab report 2.
- The title also includes some information about the experiment it is, a cross sectional study.
Abstract:
Lab Report 1:
- This abstract is good as it provides the necessary information about the survey.
- This abstract makes a good overview of the lab report as it discusses purpose, method, results, and conclusion which are all labeled.
- It provides enough detail so that the reader gets an idea of what the lab report will be about
Lab Report 2:
- This abstract is also good as it gives enough detail to get an idea of what the lab will be about. Every section is summarized very well.
- The method is summarized with the most detail, but everything else is quite brief.
- This is unlike Lab Report 1, where the abstract was the results were mostly in detail with everything else brief.
Lab Report 3:
- This abstract is also good and well organized.
- It includes the introduction, methods, results, and discussion, each labeled and easy for the reader to see.
- Each section summarized in this abstract is in enough detail for the reader to know about the experiment.
Introduction:
Lab Report 1:
- This introduction introduces the reader to individual sleep positions and sleep habits.
- It goes into detail about the different habits such as the tendency of turning many times in sleep.
- This introduction, introduces the relationship of sleep position with other variables such as sleep quality and body pain. The problem is being stated in this section.
Lab Report 2:
- This introduction discussed several issues related to sleep quality.
- It also mentioned a relationship between sleep position and sleep quality.
- There is a discussion about which other factors affect sleep quality as well, such as mattress pressure, however, sleep posture is the most reasonable variable.
Lab Report 3:
- This introduction also discusses factors involving sleep quality such as sleep position.
- There is a discussion of different problems related to sleep and their causes and consequences, including spinal pain.
- This introduction still discusses sleep posture as a reasonable variable that affects sleep quality like in lab reports 1 and 2. However, pain and other variables are also described as causes for low sleep quality.
Materials and Methods Results:
Lab Report 1:
- The method of this study is by taking a survey of a sample of a community in South Australia. The sample was every three houses apart in the community and they were surveyed via phone call.
- Participants taking the survey had to state which sleep position they are in most frequently as well as if they had any medical conditions and for a rating of their usual sleep quality.
Lab Report 2:
- The method of this study conducted an experiment in which a device was used. This was unlike Lab Report 1 when a survey was used.
- This was a sensor which monitored the sleep of the participant. The sample included participants who usually track their sleep with a monitor.
- The participants were asked to change their sleep positions over night.
Lab Report 3:
- The method of this study also conducted an experiment.
- Similar to Lab Report 1 there was initially a survey conducted. However, after this survey the experiment was conducted which observed how the participants sleep over many nights based on their waking symptoms, such as cervical or lumbar pain.
- Similar to Lab Report 2, an experiment was conducted which measure sleep quality in different participants. However, in this experiment the participants were allocated based on their waking symptoms or were in the control group.
Discussion:
Lab Report 1 :
- In the results of this lab report, it is found that participants who sleep in a side lying position were less likely to have waking symptoms.
- Those who had slept in a supine position show no major change in their waking symptoms. The participants with the most waking symptoms had slept in an upright position.
Lab Report 2:
- The results of this lab report show that the quality of sleep in the participants was inversely proportional to the amount of times they were tossing and turning.
- It shows that the sleep position of the participants was also a factor of sleep quality as those who slept on their right side had a better quality of sleep.
- The results from best to worst sleep quality are right side, left side and supine position. This is similar to Lab Report 1 where sleep position has an affect on the quality.
Lab Report 3:
- In this discussion, the Control group had better sleep quality than the symptomatic groups. The conditions with lower sleep quality had more turning and posture change.
- This is similar to Lab Report 2 where both constant turning and posture were big factors in sleep quality. From all 3 lab reports we can see that position is a major factor of sleep quality.
Conclusion:
Lab Report 1:
- The conclusion says that sleeping on your right side lowers the chance of waking symptoms and high sleep quality ratings. This position is recommended as a sleep position of choice.
Lab Report 2:
- The conclusion says that it is unknown if sleep posture affects spinal pain. However, those in a condition of cervical pain had slept in uncomfortable sleep positions.
Lab Report 3:
- There was a limitation section instead of conclusion for this lab report which states that the participant could have had specific first- night effects.
- This could have caused them to be anxious, stressed, and could have affected their sleep. However, this data recording the first- night was discarded.
References & Appendices:
Lab Report 1:
- The appendix includes the information about the survey. The references seem like they were in a good format, but not in order.
Lab Report 2:
- There was no appendix and the references seemed fine.
Lab Report 3:
- There was no appendix and the references seemed fine.
