JOINT POWER AND ITS RELATIONSHIP TO THE FATIGUE OF HUMAN BODY

In this study, the joint power and its relationship to levels of fatigue in the human body during vertical jumps was examined. The jumping movements, which were performed before and after a 30-second period of pedaling on a Monark bicycle ergometer, were video recorded. The video materials were then analyzed on a motion analysis system. The ground reaction force during jump was measured by a force platform. The joint power was calculated using the data from the above systems. The two groups of data were compared. The variation of joint power at each joint was computed and a quantitative description of the resulting fatigue was obtained

The impact of chronic airway disease on symptom severity and global suffering in Canadian rhinosinusitis patients

Background: Patients with Chronic Rhinosinusitis (CRS) can suffer from a significant decline in their quality of life. CRS patients have a high prevalence of comorbid conditions and it is important to understand the impact of these conditions on their CRS-related quality of life. This study measures the impacts of chronic pulmonary comorbidities on quality of life, pain, and depression scores among patients with CRS awaiting Endoscopic Sinus Surgery (ESS). Methods: This study is based on cross-sectional analysis of prospectively collected patient-reported outcome data collected pre-operatively from patients waiting for ESS. Surveys were administered to patients to assess sino-nasal morbidity (SNOT-22), depression and pain. The impact of pulmonary comorbidity on SNOT-22 scores, pain and depression was measured. Results: Two hundred fifthy-three patients were included in the study, 91 with chronic pulmonary comorbidity. The mean SNOT-22 scores were significantly higher among patients with chronic pulmonary comorbidities than among patients without (37 and 48, respectively). This difference is large enough to be clinically significant. Patients with chronic pulmonary comorbidities reported slightly higher depression scores than those without. Conclusions: This study found that among CRS patients waiting for ESS, chronic pulmonary comorbidities are strongly associated with significantly higher symptom burden.Medicine, Faculty ofOther UBCNon UBCSurgery, Department ofReviewedFacult
