Validity and reliability of the Turkish version of the Physical Workload Questionnaire

Cross-cultural adaptation, validation and psychometric properties of the Arabic version of the Nordic Musculoskeletal Questionnaire in office working population from Saudi Arabia

BACKGROUND

Office-workers who suffer from musculoskeletal pain/disability may experience reduced productivity and absenteeism from work. The Nordic Musculoskeletal Questionnaire (NMQ) is a valid, simple screening tool for the history and presence of self-perceived musculoskeletal symptoms in both general public and occupational settings.

OBJECTIVE

To translate and culturally adapt the NMQ into Arabic language and examine its psychometric properties.

METHODS

The published guidelines were followed to translate and adapt the NMQ into Arabic using a forward-backward process. Construct validity involved comparing NMQ responses with disability-related musculoskeletal questionnaires in different body regions, including the Neck Disability Index (NDI), Oswestry Disability Index (ODI), Quick-Disability of the Arm, Shoulder, and Hand (Quick-DASH), and Reduced Western Ontario and McMaster Universities Osteoarthritis Index (ArWOMAC). The reliability was evaluated using Cronbach's alpha for internal consistency and prevalence-adjusted bias-adjusted kappa (PABAK) for test-retest reliability.

RESULTS

The Arabic NMQ (Ar-NMQ) revealed excellent internal consistency (Cronbach's alpha = 0.85). For the test-retest reliability, the PABAK coefficient ranged between 0.50 and 1. The Ar-NMQ demonstrated strong construct validity. Participants reporting neck pain showed significantly elevated disability scores on the NDI (p < 0.05), while those with back pain exhibited higher ODI scores (p < 0.05). Moreover, individuals reporting shoulder, elbow, and wrist pain and disability displayed elevated Quick-DASH scores (p < 0.05). Similarly, participants reporting hip/thighs, knees, and ankle/feet pain/disability demonstrated significantly higher disability in ArWOMAC (p < 0.05).

CONCLUSION

The NMQ was successfully translated and adapted into Arabic language, providing a reliable and valid instrument for assessing pain in specific body regions in the Arabic-speaking population.

Effects of a Family Caregiver Care Programme in Musculoskeletal Pain and Disability in the Shoulder-Neck Region-A Randomised Clinical Trial

Life expectancy in Spain has increased and older people need more health care to improve their quality of life. The high demands of the population sometimes collapse health services, making them insufficient to cover their needs, which leads to the development of “non-professional caregivers”. These caregivers have suffered musculoskeletal injuries of the cervical spine and shoulders and should be guided and assessed on ergonomics, biomechanics, or kinesiotherapy. However, there are no interventions to help them care for themselves. This study presents the application of a physical exercise programme to prevent these disorders in women caregivers of dependent patients. It consists of a randomised controlled clinical trial with two groups: both received a family caregiver care programme, and the intervention group also received a physical therapeutic exercise programme for 12 weeks. A total of 62 caregivers completed the study, who were mostly daughters or wives of dependents. Of these, 70.97% presented a “moderate” pain intensity and a cervical disability of 13.72 ± 7.64 points in the NDI questionnaire in the initial evaluation. In the intervention group of caregivers, there was a significant decrease in the pain intensity and a significant increase (p < 0.05) in all cervical joint amplitude movements. Caregivers present a high prevalence of musculoskeletal disorders. The physical exercise programme was effective in reducing the intensity of pain, lumbar disability, and cervical disability of the family caregivers.

Physical workload during caregiving activities and related factors among the caregivers of children with cerebral palsy

BACKGROUND

Caregiving demands contribute to both psychological and physical health of caregivers. Physical workload (PW) can be an important cause of musculoskeletal disorders in caregivers of children with cerebral palsy (CP).

AIMS

To investigate PW during caregiving activities and related factors among caregivers of children with CP.

METHODS

Children with CP (n = 291) and their caregivers (n = 291) were recruited for this cross-sectional study. Caregivers were categorized as their child has presence of intellectual disability (ID) and independent walking ability. Gross motor function was assessed using the Gross Motor Function Classification System (GMFCS) in children. PW; presence and distribution of musculoskeletal pain sites; levels of disability of neck, low back, arm, and leg; levels of depressive symptoms; and health-related quality of life (HRQOL) were assessed in caregivers.

RESULTS

Significant differences were observed in PW, low back pain-related disability, depressive symptoms, and HRQOL between caregivers of children with and without an ID (p < 0.05). All study variables were significantly different between caregivers of children who can and cannot independently walk (p < 0.05). PW was correlated with caregiver's age, body mass index, lower extremity dysfunction, depressive symptoms, and child's GMFCS level (p < 0.05).

CONCLUSIONS

Caregivers of a child having an ID and walking disability had higher PW. These caregivers had more problems related to musculoskeletal disorders, higher depressive symptoms, and lower HRQOL. Higher PW was associated with lower level of gross motor function of child and older age, higher body mass index, higher level of lower extremity disfunction and low back pain disability, and lower HRQOL of caregivers.
