Type and purpose

of study


Type means qualitative, quantitative, or mixed methods research.


What is the authors’ purpose of the study?

The author’s purpose of the study was to find out whether progressive and intensive physical exercise is ideal in improving the quality of life to patients who have undergone a lumbar microdiskectomy.

The author used sampling as a research method where he used a group of people with different characteristics to come up with reliable findings.

Hypothesis or Research Questions

What questions guided the study?

The questions that guided the study included: do people who have undergone lumbar microdiskectomy experience an improvement of life after extensive and progressive exercise program? What are the factors that increase the quality of life to patients who have undergone recent lumbar microdiskectomy




Who was studied and how many participants were used?

176 patients were used in the study and screened.

Out of 176 of them, 98 were categorized into either education or exercise (n = 51) or education only (n = 47). Among the 98 patients, 77 were the ones who completed evaluations at the specified periods. Demographic information of the participants of the exercise and education (n =45) Or education only (n = 32) groups were presented. Further, participants were categorized

into 3 different groups which included exercise and education(n = 43)

education only (n = 14), and the normal physical therapy

(n = 20). Among the participants who completed the intervention timeframe, 3.9% of them completely experienced an adverse experience. Analyses which were performed on the measures of outcomes for the two-group were also provided. The ANCOVA results indicated great differences as indicated in the post-intervention statistics which were between the education and exercise group as well as the education-only group which was for SF-36 physical (P

= 0.012) and SF-36 pain of the body (P = 0.007), clearly indicating that the education and exercise group had significantly bigger improvement as indicated in the variables.


How was the study conducted? What measures were used?

The randomized (two group) as well as the as-treated

(three groups) findings, those patients that were treated with

Education and exercise were seen achieving bigger improvements in SF-36 bodily pain and role physical scales as well as the physical characteristics analysis. Moreover, as indicated in the as-treated analysis, the education and exercise group showed improvements which were higher in SF-36 physical role scale. There was no difference that was noted between education and exercise and the group of education. This can be well explained by the great loss of crucial statistical power as a result of the big number of those who participants and did not fall under the education-only group. There is a similarity between the result of the study at hand and those of Hart as well as colleagues12. In the later study, larger improvements in the SF-36 scores were well achieved as indicated in a group of participants who were participating in areas and conditions which had high-intensity lumbar extensor program in comparison with control and low-intensity groups.

Findings and Conclusions

What findings were made in this study and what was the conclusion(s)?

In both the two-group testing, education and exercise resulted in an increase which was greater in role physical (17.8 vs. 12.1), SF-36 scales, and bodily pain (13.4 vs. 8.4) as well as the physical characteristics summary of (13.2 vs. 8.9). as indicated in the three-group testing and analyses, post-hoc relationship indicated exercise and education had a greater improvement in the SF-36 scales, bodily pain (13.7 vs. 8.2) and physical function (10.4 vs. 5.6) and the summary of physical component (13.7 vs. 8.9) as if they were compared to normal physical therapy.

The conclusion: An intensive and progressive exercise program which is combined together with education usually increases the quality of

life in those patients who recently underwent a lumbar microdiskectomy (Menon, Ho & Ciacci, 2011)



How does this article impact interactions with your future patients?

This article is essential because it will help me understand the factors that improve the quality of life to those patients who have recently undergone lumbar microdiskectomy (Boschert, 2005). This will help me to base my advice to such patients so that they can achieve better living standards after undergoing lumbar microdiskectomy.
