Nurses and nursing aides suffer from work-related pain and musculoskeletal disorders (MSDs). Although there have been a plethora of studies on MSDs, an overall understanding of the prevalence of MSDs and pain can lead to better prioritization of research needs with respect to the health care industry. A total of 132 articles on prevalence of MSD pain and injuries were included in the review. All articles were published in peer-reviewed English-speaking journals and subjected to a quality review. Reported prevalence of MSD pain for nurses and nursing aides was highest in the low back, followed by shoulders and neck. However, the majority of the studies have been concentrated on 12-month pain in the low back and predominantly in hospitals. Few researchers have investigated pain in the upper and lower extremities (less than 27% of the studies). Even fewer re...

The objective of this study was to investigate the short-term impact on the restoration of the functional ability of common treatment modalities including physical therapy, acupuncture, chiropractic treatment, and massage therapy. A within subjects design was used that compared a baseline assessment to three follow-up assessments: immediately following treatment, two days and seven days post treatment. Individuals suffering from low back pain were recruited from local clinics that specialize in one of the four treatment modalities. Twenty-four individuals who were suffering from low back pain and started one of the treatment modalities were recruited into the study. Three-dimensional motions (ROM, velocity, and acceleration) during a standardized functional capacity protocol were measured prior and during three follow-up periods. The results show the effectiveness of the treatments was dependent upon time and were predominantly in the non-sagittal motion planes (velocities and accelerations). Individual subjective pain levels also indicate all the treatment modalities were effective after the 1-week follow-up. Findings suggest those modalities primarily focused on the back musculature (acupuncture, massage, physical therapy) were more effective with respect to functional capacity restoration. The current results provide a quantitative evaluation, based upon trunk dynamics, of the effectiveness of these four treatment modalities.

The current study evaluated nine males and nine females while lifting two box weights (9.1 kg, 18.2 kg) from five origins below the waist (0, 19, 38, 57, and 76 cm above the floor) and from three task asymmetries (sagittally symmetric, 45 • clockwise, 45 • counter-clockwise). While the lifting style was significantly influenced by the height of lift origin and to a lesser extent gender, box weight, and task asymmetry, none of the conditions resulted in pure squat or stoop lifting style. However, for lifts above knee height, the lifting style resembled more of a stoop lift while lifts originating below knee height were more of a squat lift. As the origin moved closer to the floor, participants relied more on their hips to accomplish the sagittal flexion but overall adopted a more coordinated whole-body lifting style. All together, as more sagittal flexion is required, more joints are relied upon in a more coordinated effort. The current study indicates that caution needs to be exercised when applying results of pure squat or pure stoop lifting studies to free-style (realistic) lifting.

However, this common practice prescribes the position of the bed and not of the patient, which could be significantly different. The aim of this research was to determine the relationship between patient migration in bed and anatomic torso angle. Ten healthy participants were positioned in a hospital bed that was raised from flat to 30° and 45° HOB elevations. Prior to bed movement, participants were aligned to different locations along the length of the bed to represent different amounts of migration. A motion capture system was used to measure torso angle and migration toward the foot of the bed. The relationship between torso angle and migration was estimated by linear regression. Patient migration resulted in lower torso angles for both 30° and 45° HOB articulations. A migration of 10 cm resulted in a loss of 9.1° and 13.0° of torso angle for HOB articulations of 30° and 45°, respectively (for 30° articulations: (Equation is included in full-text article.)= -0.91, R = .96; for 45° articulations: (Equation is included in full-text article.)= -1.30, R = .98). Migration toward the foot of the bed flattens the torso. To maintain a torso angle that is likely to protect against VAP, healthcare providers need to manage both HOB angle and migration. Protocols and equipment that minimize patient migration will help support effective clinical practice. Future research on patient migration, as it relates to VAP or other outcomes, should measure patient torso angle to allow accurate translation of the results to care practice.

Migration may cause shear and friction between the patient and the mattress, reduce elevation of the patient's torso, and require frequent repositioning of the patient. This study assesses how bed design impacts both the amount of migration that patients undergo during head section articulation to 30° and 45° and the extent of torso compression following the articulation.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.
