Download file to see previous pages According to Davis (2003), there is no difference in the use of CPM postoperatively or not. This study used randomized patients studied in three different groups through a six month period. They looked at the length of stay, pain control and flexion of the knee. The results of the research should that there was no difference in the range of motion, pain, or utilization of services between patients that had just physical therapy and patients who also have CPM. This was supported by a study done by Denis This group performed a randomized control trial that was very similar and weighted the use of CPM in different intervals ranging from 35 minutes per day to continuous ROM. These were compared to patients who had active physical therapy. The results showed that there was no difference between the results of each of the combinations of therapy.
The controversy comes when Wells (2008) did a meta-analysis of 14 studies. This analysis showed that in 14 randomized control trials the results were that CPM and PT increased active knee flexion and reduced hospital stay as well as pain and increased range of motion. Again, however, in the study done by Bruun-Olsen (2009) in a randomized control trial done with active exercises versus CPM, results were very similar to other studies noted for this paper. There were no statistical differences noted between the control group and the trial group. Lenssen (2008) essentially agree in his comparison of CPM during the 1st rehab phase to active physical therapy without CPM. This study shows only slight improvement with the use of CPM and is supported by Grilla (2008) who finds no support for CPM as improving any outcomes.
In conclusion, of the six studies that were reviewed, only one supported the use of CPM for increased motion, reduced length of stay or reduced pain. One, which was a meta-analysis did support it but is vague in its content. From these six studies alone, there is no evidence-based answer. There is a reason to further research the use of CPM in the post of knee replacement. ...Download file to see next pagesRead More

Passive movements

... and movement are essential for the development, maintenance, and continuing health of the musculoskeletal tissues. Inactivity or trauma can result tissue changes with abnormal symptoms and dysfunction. The greater the inactivity, both in terms of intensity and duration, the greater the damage. If healing has to take place, a tissue response has to be incited so as to restore tissue structure and function, and this can basically be facilitated by loading and motion. Joint mobilization consisting of passive movements is an important part of the treatment stimulating tissue healing. A variety of passive movements such as oscillation and repetitive traction modulate pain, enhance muscle tone, increase nutrition available to the tissues...

Active and Passive Euthanasia

...James Rachels, in his 1975 essay, “Active and Passive Euthanasia,” s the American Medical Association’s (AMA) stance on euthanasia, which sthat doctors should not actively end the life of their dying patients, is morally and philosophically untenable. He uses four arguments to support his position. These arguments are that active euthanasia is often more humane than passive euthanasia, that the AMA’s position often leads to making decisions on irrelevant grounds, and that there is no difference morally between killing someone and letting someone die. Rachels also believed that the common arguments supporting passive euthanasia were invalid. Rachels uses several stories to illustrate his arguments, the most famous of which is the man...

Relevant Merits of Theoretical Approaches to Counseling

...Critically discuss the relevant merits of two or more theoretical approaches to counselling The conviction has been gaining ground that there are as many theoretical orientations in counselling as there are individual counsellors or, put in a slightly different way, therapists from varied theoretical orientations and backgrounds are reportedly very similar in their conceptualization of the ideal therapeutic practice and outcomes (Fiedler 1951). There is evidence to conclude that common features shared by all psychotherapies underlie and override differences in their use of technical knowledge (Stiles, Shapiro and Elliott 1986) .

To What Extent Can Religious Motives Be Used in Cartoons and Motion Pictures without Offending Various Religious Groups

...To what extent can religious motives be used in cartoons and motion pictures without offending various religious groups? Background The problem ofcensorship has always been prevalent in civilised society since age old. According to Jansen (1991), despite scientific and social progress, the freedom phenomenon still faces obstruction and distortion from religious censorship. This domain has always been controversial because the knowledge secured by human interests tends to differ to those of religious traditions. Even in modern age of reason, censorship "is an enduring feature of all human communities" (Jansen 1991, p.4). It is therefore not surprising when the balance of freedom of speech has been toppled over with the recent publication...
