Sarcopenia is recognized as a major health problem among older adults. This syndrome is associated with serious health consequences in terms of frailty, disability, morbidity and mortality. The aim of this study is to review sarcopenia and its impact on quality of life (QoL). MEDLINE database was searched from January to March 2016 using predefined search terms "sarcopenia", quality of life". Based on extensive literature search, 32 articles were identified while only 6 studies met the inclusion criteria and were associated with sarcopenia and QoL. Quality of life level was measured using generic self-reported tools; the Medical Outcomes Survey Short-form General Health Survey (SF-36) in 4 studies and EuroQol-5D instrument (EQ-5D) in 2 studies. Subjects with sarcopenia demonstrated a significantly high proportion of problems relating to several dimensions of QoL. More studies based on Sarcopenia and QoL are needed. Although the impact of sarcopenia on QoL was assessed in all studies with QoL generic instruments, it would be more insightful to utilise a disease-specific quality of life questionnaire, such as the SarQoL for sarcopenic subjects.

The study was aimed at examining the reliability of the Double Inclinometer (DI) method for the assessment of thoracolumbar Range of Movement (ROM) and Joint Position Sense (JPS) in patients with a recent history of Low Back Pain (LBP). Twenty patients with a history of LBP in the last three months participated. The thoracolumbar ROM and JPS were examined from a standing position by using both the DI and the tape measure method. The DI method was found to have moderate to good intra-rater (ICC = 0.68–0.79, SEM = 2.20–2.77°, SDD = 6.09–7.67°), moderate inter-rater (ICC = 0.59–0.62, SEM = 2.96–3.35°, SDD = 8.19–9.27°) and poor test-retest reliability (ICC = 0.13–0.17, SEM = 3.98–4.32°, SDD = 11.02–11.96°) for the assessment of thoracolumbar JPS. For the assessment of thoracolumbar ROM, the DI method was found to have good to excellent intra-rater (ICC = 0.88–0.94, SEM = 4.25–6.20°, SDD = 11.77–17.17°), excellent inter-rater (ICC = 0.90–0.91, SEM = 7.26–7.74°, SDD = 20.11–21.43°) and excellent test-retest reliability (ICC = 0.91–0.93, SEM = 6.03–6.87°, SDD = 16.70–19.02°). The concurrent validity of the DI method with the tape measure method was found to be very weak for the assessment of thoracolumbar JPS (r = 0.02, p = 0.93) and strong for the assessment of thoracolumbar ROM (r = 0.66, p = 0.001). The DI method seems to be a very reliable method for the assessment of thoracolumbar ROM in individuals with a recent history of LBP.
