Models of care for musculoskeletal shoulder pain in spinal cord injury: A scoping review

CONTEXT

Spinal cord injury (SCI) is a neurological condition that significantly impacts a person's lifestyle, health and well-being. Many individuals with SCI experience secondary musculoskeletal shoulder pain. This scoping review examines the current research on the diagnosis and management of shoulder pain in SCI.

OBJECTIVE

The aim of this Scoping Review was (1) to chart peer-reviewed literature regarding the diagnosis and management of shoulder pain as it relates to SCI and (2) identify gaps in this body of literature to inform future research priorities.

METHODS

Six electronic databases were searched from inception until April 2022. In addition, reviewers scanned the reference lists of identified articles. Articles from peer-reviewed sources that reported diagnostic or management procedures for musculoskeletal shoulder conditions within the SCI population were considered and 1679 articles were identified. Title and abstract screening, full text review, and data extraction were undertaken by two independent reviewers.

RESULTS

Eighty seven articles were included, covering diagnosis or management of shoulder pain in SCI.

CONCLUSION

Whilst the most commonly reported diagnostic procedures and management strategies reflect contemporary practice for shoulder pain, the entire body of literature demonstrates inconsistencies in methodologies. In places, the literature continues to perceive value in procedures inconsistent with best practice. These findings encourage researchers to pursue the development of robust models of care for musculoskeletal shoulder pain in SCI using a collaborative and integrated approach, combining best practice for musculoskeletal shoulder pain alongside clinical expertise in the management of SCI.

Relationship between Upper Limb Functional Assessment and Clinical Tests of Shoulder Mobility and Posture in Individuals Participating in Recreational Strength Training

BACKGROUND

The upper limb is crucial for functioning in everyday life, thus comprehensive assessment is crucial for physically active people to monitor the effect of exercise and prevent injuries. The aim of this study was to analyse the relationship between upper limb function, shoulder mobility, and posture in individuals who participate in recreational strength training.

METHODS

Thirty-four subjects who engaged in strength training of the upper limbs were divided into two groups: Group 1 (exercise < 3 years) and Group 2 (exercise ≥ 3 years). Lateral scapular slide tests, head and clavicle posture evaluations, and shoulder mobility and closed kinetic chain tests were performed.

RESULTS

Group 1 had a greater flexion deficit in both shoulders than Group 2. There was greater external rotation in the non-dominant shoulder and a greater score of the closed kinetic chain test in Group 2 compared to Group 1. There were no statistically significant differences between groups regarding scapula, clavicle, and head posture. The closed kinetic chain test was correlated with a scapula position and symmetry in shoulder flexion in Group 2.

CONCLUSIONS

Long-term strength training of the upper limbs can be recommended to improve functional abilities in the closed kinetic chain, increase shoulder mobility, and reduce asymmetry.

[Identification and Prioritization of Research Questions on Paraplegia Caused by Traumatic Spinal Cord Injury with Those Affected, Their Relatives and Health Care Professionals]

BACKGROUND

Objective With expertise based on experience, paraplegics, their relatives and health care professionals can contribute to the development of research questions relevant for those affected and those in health care practice. For this purpose, the James Lind Alliance (JLA) has provided a methodological approach. The aim of this study was to develop a research agenda for paraplegia resulting from traumatic spinal cord injury with an adapted JLA approach.

METHODS

Four consecutive online surveys of people with paraplegia caused by traumatic spinal cord injury, their relatives and caregivers were conducted. In the first survey, the respondents freely formulated research questions unanswered from their point of view. These were synthesized and checked to see if they can already be answered by available evidence. The unresolved questions were prioritized stepwise in the subsequent surveys. In the second survey, the relevance of questions was rated on a five-point rating scale (1-5). Questions with a mean value of 4 or higher were taken up in the third survey, in which the 10 most relevant questions were determined. These were ranked in the fourth survey as a top-10 list.

RESULTS

Based on the first survey (n=52), 38 unresolved research questions were identified. Of these, 26 questions were rated as important (2nd survey; n=53), from which 10 questions were selected (3rd survey; n=17) and ranked (4th survey; n=12) as a top-10 list. Four prioritized questions related to treatment of spinal cord injury or associated health issues, three to aspects of the health care system with regard to assistive devices and the implementation of new therapies, two to possibilities of those affected to improve their own situation, and one to research on the course of disease.

CONCLUSIONS

Nine priorities focus on research that could help improve the life and health care situation of paraplegic patients and one on curative treatment. The prioritized questions should be taken up by researchers and research funders for the benefit of patients and to help health care providers. For some priorities, a need for research was consistently identified in present guidelines or systematic reviews.

Assessment of shoulder rotation strength, muscle co-activation and shoulder pain in tetraplegic wheelchair athletes - A methodological study

Objective: To develop a feasible protocol for testing maximum shoulder rotation strength in tetraplegic wheelchair athletes, and investigate concurrent validity of maximum isometric handheld dynamometer (HHD) towards maximum isokinetic dynamometer (ID) strength measurements; secondly, to study shoulder muscle activation during maximum shoulder rotation measurements, and the association between shoulder strength and shoulder pain.Design: Descriptive methodological.Setting: Danish Wheelchair Rugby (WCR) association for WCR tetraplegic athletes from local WCR-clubs.Participants: Twelve adult tetraplegics.Interventions: N/A.Outcome measures: Wheelchair User's Shoulder Pain Index (WUSPI) and Visual Analog Scale (VAS) measured shoulder pain, isometric HHD and ID (60°/s) measured maximum internal (IR) and external (ER) shoulder rotation strength. Surface Electromyography normalized to maximum EMG measured muscle activity (mm Infraspinatus and Latissimus Dorsi) during maximum shoulder rotation strength.Results: Concurrent validity of isometric HHD towards ID showed Concordance Correlation Coefficients of left and right arms 0.90 and 0.86 (IR), and 0.89 and 0.91 (ER), with no difference in muscle activity between isometric HHD and ID, but larger co-activation during ER. There was no association between shoulder strength and pain, except for significantly weak negative associations between ID and pain during ER for left and right arms (P = 0.03; P = 0.04).Conclusion: Standardized feasible protocol for tetraplegic wheelchair athletes for measuring maximum shoulder rotation strength was established. Isometric HHD is comparable with ID on normalized peak torques and muscle activity, but with larger co-activation. Strength was not clearly associated with shoulder pain.

Longitudinal Examination of Leisure-Time Physical Activity (LTPA), Participation, and Social Inclusion Upon Joining a Community-based LTPA Program for Adults With Physical Disabilities

OBJECTIVE

First, to examine whether participants reported changes in (1) leisure-time physical activity (LTPA) participation and social inclusion variables and (2) well-being outcomes before and after joining a community-based LTPA program for adults with physical disabilities. Second, to explore the longitudinal relationship between LTPA and the other aforementioned outcomes.

DESIGN

A double baseline longitudinal design with measurements at 4-6 weeks (baseline 1) and immediately (baseline 2) before and 2 and 4 months after joining the community-based LTPA program.

SETTING

Community.

PARTICIPANTS

Adults (N=43) with a physical disability who reported no cognitive impairment, were new members of the community-based LTPA program, and spoke English or French.

INTERVENTIONS

A community-based physical activity program for adults with physical disabilities. Participants were provided an individualized exercise program and accessed the program at designated times during the week.

MAIN OUTCOME MEASURES

Primary: LTPA (LTPA Questionnaire for People with Spinal Cord Injury), participation (Patient-Perceived Participation in Daily Activities Questionnaire), and social inclusion. Secondary: depression severity, self-esteem, resilience, and life satisfaction.

RESULTS

After joining the program, participants reported an increase in total LTPA (mean_baseline2, 177.80±211.32; mean_2months, 299.31±298.70; mean_4months, 288.14±292.14), moderate-to-vigorous LTPA (mean_baseline2, 83.95±123.95; mean_2months, 142.00±198.38; mean_4months, 163.23±182.08), and participation in health (mean_baseline2, 6.24±1.16; mean_2months, 6.58±1.25; mean_4months, 6.97±0.82) and family-related activities (mean_baseline2, 12.18±2.43; mean_2months, 12.60±2.30; mean_4months, 13.47±2.01). A significant increase (β=3.46, P<.001) in social inclusion before joining the program was followed by a decrease (β=-1.09, P<.05) 4 months later. Improvements related to depression severity were noted (β_{baseline1-baseline2}=-1.51, P<.05; β_{baseline2-4 months}=-0.28, P>.05).

CONCLUSIONS

The results support the role of a community-based LTPA program in increasing LTPA levels and enhancing participation in some activities among adults with physical disabilities.
