The data also consistently indicate that fatigue etiology was related to the presence of pain.  Murphy et Al (2013) examined how fatigue in daily life is related to subsequent physical activity among fatigued people with knee and hip OA and concludes that daily experiences of fatigue were negatively and robustly related to subsequent physical activity. Further analyses revealed that the effect was strongest for people with the highest functional mobility, providing some support for a tailored approach to fatigue management in OA based on functional mobility.  Khan et al reported that the prolonged use of mobile phones is associated with a greater frequency of neck pain and a higher NDI score. There is a significant positive correlation exist between text neck syndrome and mobile phone usage. Initially, the musculoskeletal changes are short term but can cause disabilities in later life if proper care and prevention are not taken  Parmakovska et al (2016) highlighted in her research that 62.5% patients undergoing haemodialysis experienced muscle cramps usually in lower legs at least once weekly and most commonly experienced severity score being 5 i.e. in 26.15% patients.. In a study conducted by Brita et al (2014) concluded that 15.3% of respondents said that their work as a Physical therapist interfered with their private and family life.
