Methods and results

JBI methodology for scoping reviews and an a priori registered protocol (DOI 10.17605/OSF.IO/8PR7A) was followed and AMED, CINAHL, MEDLINE, SPORTDiscus and EMBASE databases were searched. Literature published in English between 2002 and 2021 was included.

Forty-nine records were included: 36 primary research studies, 1 systematic review and 12 ‘other’ including narrative and government reports. Primary research predominantly used observational cross-sectional designs (n = 21 studies). Most studies took place in hospitals (n = 13) and laboratories (n = 12). Nurses formed the largest population group (n = 13), with very little research on physiotherapists and other allied health professionals.

Methods and Results

Key informant interviews were conducted with 4 physiotherapy operational leads and 1 manual handling trainer from NHS Grampian. Interviews were transcribed and Framework Analysis was utilised to identify key themes, including challenges, barriers, and facilitators. Following this, two online focus groups were conducted with 7 qualified NHS physiotherapists across the UK. Views of manual handling training varied across specialities, with some finding it comprehensive and adaptable, and others finding it less applicable to patients in their speciality or community setting. Physiotherapist views on fitness for work varied, with some highlighting the necessity of TE to ensure workforce health whilst others considered exercise to be a personal matter. Facilitators to implementation identified by participants were having support from management and a strong justification for the exercise content. Varied work schedules and facilities were identified as barriers to implementation of a work-based TE intervention.

Methods and Results

A descriptive cross-sectional study was completed to explore and quantitatively measure the movement of ten physiotherapists during patient handling, over one working day, in a neurological setting. A wearable 3-dimensional motion analysis system, Xsens (Movella, Henderson, NV), was used to measure physiotherapist movement and postures in the ward setting during patient treatment sessions. The resulting joint angles were reported descriptively and compared against a frequently used ergonomic assessment tool, the Rapid Upper Limb Assessment (RULA).

Physiotherapists adopted four main positions during patient handling tasks: 1) kneeling; 2) half-kneeling; 3) standing; and 4) sitting. Eight patient handling tasks were identified and described: 1) Lie-to-sit; 2) sit-to-lie; 3) sit-to-stand; facilitation of 4) upper limb; 5) lower limb; 6) trunk; and 7) standing treatments; and 8) walking facilitation. Kneeling and sitting positions demonstrated greater neck extension and greater lumbosacral flexion during treatments which scores highly with the RULA.

Methods and Results

Statistical shape modelling was used to characterise spinal shape (L5-T10) and identify modes of variation in shape (SM) from dual energy x-ray absorptiometry images of the spine taken at age 60–64 years (N=1327 individuals; 51.8% female). Associations between walking age in months (reported by mothers at 2 years) and SMs were examined with adjustment for sex, birthweight, socioeconomic position, height, lean mass and fat mass.

Later onset of independent walking was weakly associated with greater lordosis (SM1; P=0.05) and more uniform antero-posterior vertebral size along the spine (SM6, P=0.07). Later walking age was also associated with smaller relative anterior-posterior vertebral dimensions (SM3) among women whereas the opposite was found for men (P <0.01 for sex interaction).

Methods

Thoracolumbar spine shape was characterised using statistical shape modelling on lateral dual-energy x-ray absorptiometry images, recorded for vertebral fracture analysis, of the spine from 1529 participants of the MRC National Survey of Health and Development, acquired at age 60–64 years. Associations between spine shape modes (SM) and 1) sex, 2) contemporaneous measures of overall and central adiposity (indicated by body mass index and waist circumference, respectively), 3) changes in total and central adiposity during earlier stages of adulthood and age at onset of overweight, were investigated.

Methods:

Magnetic resonance imaging (MRI) was performed in standing and bending forward to 30, 45 and 60°, with markers on the skin at L1, L3, L5 and S1. Lumbar spine shape was characterised using statistical shape modelling and participants grouped into ‘curvy’ and ‘straight’ spine sub-groups (N=8). On a separate day participants lifted a box (6–15 kg) from the floor without instruction while Vicon cameras tracked sagittal movement of L1, L3 and L5 skin markers. Sacral angle (to horizontal) was calculated from pelvic markers. Matching markers during MRI and lifting sessions allowed vertebral centroid positions (L1, L3, L5, S1) during lifting to be calculated using custom MATLAB code.

Methods

Positional MRI was used to acquire sagittal images of the lumbar spine in a standing posture in 30 healthy adults. Sacral inclination was measured and active shape modelling used to characterise lumbar spine shape. A two-dimensional model of the lumbar spine was constructed using vertebral centroid positions and a simplified representation of the lumbar extensor muscles. The muscle forces required at each level to produce a follower load were calculated using a force polygon.

Methods

Antenatal data and supine MR images of the lumbar spine were available for 161 children. Shape modelling, using principle components analysis, was performed on mid-sagittal images to quantify different modes of variation in lumbar spine shape. Previously collected measures of spine canal dimensions were analysed.
