Background: Peoples who use laptops are at greater risk for neck pain complaints. The incidence and prevalence of neck pain is increased with the development of information technology and the move toward service sector oriented employment and which is further influenced by an increase in sedentary work as well as occupational and recreational computer use. The prevalence of neck pain due to laptop use is surveyed among post-graduation students as their computing hours are higher because these students are further into their education and are completing masters requiring research.Purpose of study: To survey (a) The prevalence of neck pain due to laptop use among the post graduate students (b) To assess the laptop using behavior by using student laptop use and neck pain risk questionnaire (SLUNPRQ) developed by Gray, D.( 2011). Materials and Methods:A Qualitative survey study with questionnaire was conducted at Guru Jambheshawar University of Science and Technology, Hisar. 150 post graduate students were taken as per selection criteria which included both male and female between the age group of 21 to 25 years. Using convenience sampling, the Student Laptop Use and Neck Pain Risk Questionnaire with informed consent was distributed among 150 post graduate students. The prevalence of neck pain due to laptop use and the laptop using behavior by using student laptop use were taken as outcome measurement parameters. Qualitative Content Analysis has been used for the analysis of the data.Results: It was observed that long time use of laptop was ergonomically inappropriate. The prevalence of neck pain and other musculoskeletal problems was found higher in most of the students because of the extended use and adopting improper posture while using laptop. Poor adaptation of posture was mainly because of unawareness about laptop ergonomics. Conclusion:The present study concluded that there is higher prevalence of neck pain in post graduate students due to lack of awareness about the proper posture for laptop use among them.

Background: Knee osteoarthritis is one of the most prevalent conditions. According to world health organization the knee osteoarthritis is the fourth most important cause of disability in women and eight most important causes in men. Various methods have been used like high speed cinematography, force platform etc but no study was done by using pen marking analysis to compare the gait parameters of osteoarthritis patients and healthy individuals. Purpose of study: To compare gait parameter that is step length, step width, stride length, walking velocity and cadence of osteoarthritis patients and healthy individuals. Materials and Methods: This experimental cross sectional study conducted at Guru Jambheshawar University of Science and Technology, Hisar. 30 subjects were taken as per selection criteria which included both male and female between the ages of 40 to 65 years. They were divided into two groups that is group A has osteoarthritis patients (n = 15) and group B has normal healthy subjects (n = 15). Step length, Step width, Stride length, Walking velocity and Cadence were taken as outcome measurement parameters. Results: Comparison was made between the gait parameters within group and between the groups by using ttest for statistical analysis. Result shows statistically significant difference in gait parameters between the patient group and healthy individuals. Patient group have lower step length (34%), stride length (33%), walking velocity (48%) and cadence (31%) and greater step width (44%) then the control group. Females with knee osteoarthritis have lower values for step length, stride length, walking velocity and cadence and greater step width then control group females. Males with knee osteoarthritis have lower values for step length, walking velocity and cadence than the control group males. Conclusion: Knee osteoarthritis shows significant difference in the gait parameters between the osteoarthritis patients and healthy individuals and between the genders.
