EXERCISE 36 Questions to be graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚p = 0.005. Discuss each aspect of these results. Answer F-value shows significance between the two groups. The null hypothesis should be rejected because the P-Value is 0.005 which would mean that the groups are different. 2. State the null hypothesis

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001.

Biomarkers in OA: A Powerful Prognostic Tool Osteoarthritis (OA) is a chronic inflammatory disease of the articular cartilage and is known as one of the most common forms of arthritis. OA results in chronic disability in its patients and compels an immense economic burden on its patients. Researchers have predicted that over the next ten years an estimated 67 million Americans over the age of 18 are going to be diagnosed with OA. Statistics like the erstwhile one motivate researchers investigating

OSTEOARTHRITIS The Pathophysiology of osteoarthritis is the affection of articular cartilage‚ along with the synovial fluid in the joint‚ permitting almost frictionless movement of joint bones at their points of contact. The frictional resistance of normal joints is the cartilage layer to absorb the shock associated with joint use. When weight is loaded onto the joint‚ the cartilage layer compresses. Once the weight is removed‚ the cartilage rebounds to its original dimensions. The articular

During the time Holden loiters in the New York after being kicked out of the school‚ he occasionally meets two types of people: a prostitute named sunny and the Nuns-two women.

The encounter with Sunny elicits misery: she is not satisfied with Holden’s five bucks‚" Ten for a throw"‚ she says. So she

that motor control exercise may be of benefit in the treatment of chronic low back pain patient populations. Motor control exercise is based on the idea that low back injuries cause inhibition of core stabilizing muscles‚ which will then atrophy over time (Hodges & Richardson‚ 1996; Richardson‚ Hodges‚ & Hides‚ 2007). Costa et al. (2009) found evidence supporting the that idea motor control exercise improves function and patient impression compared to a control group. The control group received

Chapter 11 Questions to be graded: 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Answer: Yes the experimental and control groups are similar in their feeding type because 40.6% in the experimental group decided to breast-feed‚ and 41.7% in the control group decided to breast-feed‚ that’s only 1.1% difference. 53.1% of the experimental group bottle-fed while 50.0% of the control group bottle-fed‚ a small 3.1% difference.

The purpose of the graded exercise test is to assess the cardiorespiratory capacity (VO2 max). The VO2 max is used to identify the level of cardiorespiratory fitness of the individual. Days before the graded exercise test‚ I’ll give Tonya instructions‚ such as eating breakfast‚ but no tea‚ coffee‚ and chocolate because caffeine may affect performance and results.
