The knee is the most commonly injured joint in the body with 10% of all musculoskeletal injuries that occur being sustained at the knee. 1 Knee injury increases a person’s lifetime risk of developing knee osteoarthritis (OA) approximately 4-fold compared with those who have never sustained a knee

This study assessed the prevalence of physical inactivity and the influence of sociodemographic variables on physical activity categories, highlighting the correlates of physical inactivity in Nigerian young adults.


A representative sample of young adults age 16 to 39 years (n = 1006) from a Nigerian University were categorized using the International Physical Activity Questionnaire as physically inactive, moderately active, and highly active. Prevalence rates were computed for the activity categories and the independent associations of sociodemographic correlates on each category were determined using the multinomial logistic regression.


Physical inactivity prevalence was 41%. More likely to be inactive were females (OR = 1.93; CI: 1.49−2.49), those of Hausa ethnicity (OR = 2.29; CI: 1.08−5.84), having BMI > 30 kg/m2 (OR = 2.88; CI: 1.16−7.17), and those whose parents’ annual income was < 180,000 NAIRA (OR = 1.69; CI: 1.04−2.95). Less likely to be moderately active were females (OR = 0.71; CI: 0.61−0.95), those with BMI between 25.0 to 29.9 kg/m2 (OR = 0.46; CI: 0.23−0.92), and those of Hausa ethnicity (OR = 0.17; CI: 0.04−0.74).


Important sociodemographic variables that can contribute to the preliminary analysis of correlates of physical inactivity among Nigerian young adults were identified.

older adults (OA) to continuously learn new fine motor skills and adapt skills to unknown situations. Although OA show lower fine motor control performance than young adults (YA; Diermayr, McIsaac, & Gordon, 2011 ), they are able to improve their fine motor skills considerably with practice ( Lazarus

Knee osteoarthritis (OA) affects about 30% of adults over the age of 60 years. 1 This condition is characterized by progressive degeneration of the articular cartilage in the knee joint and is accompanied by joint pain, stiffness, diminished sensorimotor function, and discomfort when performing

Knee osteoarthritis (OA) is a degenerative disease, and it usually affects medial tibiofemoral and patellofemoral compartmants. 1 Sixty-five percent of people with knee pain over 50 years or older have OA. 2 The main symptoms of OA are pain and physical disability. 3 The pathogenesis of OA is

Providing opportunities for rural-residing older adults (OA) to be physically active is important for their health and well-being. OA (65 years and older) now comprise 13.3% of the overall United States population ( Administration on Aging and the Department of Health and Human Services, 2012

Osteoarthritis is one of the most frequent musculoskeletal disorders in older adults. 1 , 2 The current global prevalence of knee osteoarthritis (OA) is 3.8%, and women are affected more often (4.8%) than men. 3 In the past, OA was generally known as degenerative cartilage decrease. Today, OA is

Objective: To assess the diagnostic validity of an isokinetic testing to detect partial injuries on the anterior cruciate ligament (ACL). Design: Prospective diagnostic study. Settings: Orthopedic clinic, physiotherapy clinic, orthopedic hospital, and diagnostic/image clinic. Participants: Consecutive patients (n = 29) with unilateral knee complaint submitted to physical examination, magnetic resonance images (MRIs), and isokinetic testing prior to surgery of ACL reconstruction. Interventions: Not applicable. Main Outcome Measures: The isokinetic torque curves data from extensor and flexor muscles were converted to frequency domain by fast Fourier transformation and compared with healthy contralateral limb. Differences were categorized as unstable knees and these conclusions were compared with patient’s physical examinations (doctor’s conclusion on ACL integrity) and MRIs (as the radiologist conclusions on ACL integrity). After surgery, all intraoperatively confirmed partial injured patient’s data were collected. The diagnostic accuracy measures to compare the conclusions of all 3 professionals included sensitivity, specificity, positive predictive value, negative predictive value, disease prevalence, positive likelihood ratio, and accuracy—all using a confidence interval of 95%. Results: Compared with MRI, the sensitivity of isokinetic test for an ACL partial injury was 90.00%, specificity 83.33%, positive predictive value 52.94%, negative predictive value 97.56%, and accuracy 84.48%. Compared with physical examination, the sensitivity of isokinetic test for an ACL partial injury was 85.71%, specificity 78.43%, positive predictive value 35.29%, negative predictive value 97.56%, and accuracy 79.31%. Conclusions: This method of isokinetic data analysis through fast Fourier transformation can be used to improve diagnostic accuracy of a difficult detection injury. Even present, a partial ACL injury can produce a stable knee during isokinetic testing and could be used to detect candidates for conservative treatment based on strengthening exercises, reducing surgery risks, and financial and social impact on patient’s life.

Osteoarthritis (OA) is a chronic disease that disables many aging adults. People with OA are often asked to adhere to prescribed exercise regimens that must be undertaken in the presence of pain and other disease-related symptoms. We conducted a review of literature that focused on what is known about exercise adherence and the factors that influence exercise adherence among people with OA. Results revealed multiple determinants of exercise adherence; however, these determinants have not been carefully studied in the context of exercise adherence and OA. Almost all studies of exercise adherence among people with OA are short-term and do not use validated measures of adherence. Moreover, poor adherence is the most compelling explanation for the declining impact of the benefits of exercise over time. We conclude that interventions to enhance self-efficacy, social support, and skills in long-term monitoring of progress are necessary to foster exercise adherence among people with OA.
