Manual handling of patients: Role of kinesiophobia and catastrophizing in health workers with chronic low back pain

BACKGROUND: Biomechanical overload due to patients' manual handling represents a relevant contributor to chronic low back pain (LBP). Fear of movement (also known as kinesiophobia) and catastrophising may influence the development of chronic complaints and lower performances also in working environments, despite these issues are poorly investigated. AIM: The aim of this study is twofold: 1) to evaluate the levels of kinesiophobia and catastrophizing in a sample of health personnel with chronic LBP and employed in activities specifically requiring patients' manual handling; 2) to appraise the influence of these factors on disability. DESIGN: Cross-sectional observational study. SETTING: Four Italian hospitals. POPULATION: Sixty-four healthcare workers suffering from nonspecific low back pain, exposed to the spinal risk of biomechanical overload due to patients' manual handling. METHODS: We assessed kinesiophobia, catastrophizing and disability by means of validated questionnaires (the Tampa Scale of Kinesiophobia [TSK], the Pain Catastrophizing Scale [PCS], and the Oswestry Disability Index [ODI], respectively). Values of central tendency and dispersion of the variable of interest were calculated, along with the association among variables through multiple linear regression analysis. RESULTS: The results showed presence of kinesiophobia (TSK=34.0; IQR=28.2-42.09), catastrophizing (PCS=20.5; IQR=10.2-29.0) and disability (ODI=28.8; IQR=13.5-40.0) in the population enrolled. Disability was significantly predicted by kinesiophobia and catastrophizing (R2=0.529 P=0.00003). CONCLUSIONS: Kinesiophobia and catastrophizing are present in health workers with chronic LBPinvolved in patients' manual handling and are linked to disability. Further investigations in this field are recommended to investigate a role for cognitive-behavioral strategies aimed at managing catastrophizing and kinesiophobia to increase working abilities. CLINICALREHABILITATION IMPACT: The assessment of catastrophizing and kinesiophobia is crucial in health workers engaged with patients' manual handling and suffering from chronic LBP.
