This survey revealed a high prevalence of shoulder pain. Sex, SCI severity, and specific health conditions were associated with having shoulder pain. Implications for rehabilitation Individuals with spinal cord injury have a high prevalence of shoulder pain. Females, individuals with complete paraplegia or any tetraplegia and individuals with contractures and spasticity should receive considerable attention in rehabilitation programmes due to their increased odds of having shoulder pain.

Handbikes come in different models and setups, but only limited knowledge is available on the handbike-user interface. The aim of this study was to identify optimal handbike setups, assuming that in such a setup mechanical efficiency is high, while shoulder load is low. Thirteen subjects with a spinal cord injury (paraplegia) performed handcycling with different handbike setups at constant power output: four crank positions (two distances, two heights) and four backrest inclinations. The O2-consumption, kinetics, and kinematics were measured to calculate mechanical efficiency and shoulder load (glenohumeral contact force, net shoulder moments, and rotator cuff force). The analysis showed that more upright backrest positions resulted in lower shoulder load compared with the most reclined position [glenohumeral contact force (260 vs 335 N), supraspinatus (14.4% vs 18.2%), and infraspinatus force (5.4% vs 9.8%)], while there was no difference in efficiency. Except for a reduction in subscapularis force at the distant position, no differences in shoulder load or efficiency were found between crank positions. Recreational handbike users, who want to improve their physical capacity in a shoulder-friendly way, should set up their handbike with a more upright backrest position and a distant crank placement.

Study design: Cross-sectional observational study with data from the 2012 community-based survey of the Swiss Spinal Cord Injury Cohort Study. Objectives: To examine the relationships between chronological age, age at injury, secondary health conditions (SHCs) and paid employment. Setting: Community setting in Switzerland. Methods: A total of 1159 individuals of working age (16-63 years for women and 64 years for men) with traumatic or non-traumatic spinal cord injury (SCI) were included in the study. Direct and indirect (via SHCs) effects of chronological age and age at injury on paid employment were tested using a decomposition method for logistic regression models. Results: Both chronological age groups (age 35-49 and 50-63/64 years) and the group with age at injury beyond 40 years showed negative direct effects on employment status. A partial indirect effect (mediation) via chronic pain was found in the group with the highest chronological age (450 years). Furthermore, pressure ulcer, pain and urinary tract infection were negatively related with employment in both models, that is, chronological age and employment and age at injury and employment. Conclusion: Being older and having a higher age at injury directly affects whether an individual is employed. Pain is mediating the relation between chronological age and employment. Furthermore, pressure ulcer, chronic pain and urinary tract infection directly reduce the likelihood to be employed and, therefore, represent important intervention targets in efforts to maintain or engage in employment of individuals with SCI.

BackgroundMedical work capacity evaluations play a key role in social security schemes because they usually form the basis for eligibility decisions regarding disability benefits. However, the evaluations are often poorly standardized and lack transparency as decisions on work capacity are based on a claimant’s disease rather than on his or her functional capacity. A comprehensive and consistent illustration of a claimant’s lived experience in relation to functioning, applying the International Classification of Functioning, Disability and Health (ICF) and the ICF Core Sets (ICF-CS), potentially enhances transparency and standardization of work capacity evaluations. In our study we wanted to establish whether and how the relevant content of work capacity evaluations can be captured by ICF-CS, using disability claimants with chronic widespread pain (CWP) and low back pain (LBP) as examples.MethodsMixed methods study, involving a qualitative and quantitative content analysis of medical reports. The ICF was used for data coding. The coded categories were ranked according to the percentage of reports in which they were addressed. Relevance thresholds at 25% and 50% were applied. To determine the extent to which the categories above the thresholds are represented by applicable ICF-CS or combinations thereof, measures of the ICF-CS’ degree of coverage (i.e. content validity) and efficiency (i.e. practicability) were defined.ResultsFocusing on the 25% threshold and combining the Brief ICF-CS for CWP, LBP and depression for CWP reports, the coverage ratio reached 49% and the efficiency ratio 70%. Combining the Brief ICF-CS for LBP, CWP and obesity for LBP reports led to a coverage of 47% and an efficiency of 78%.ConclusionsThe relevant content of work capacity evaluations involving CWP and LBP can be represented by a combination of applicable ICF-CS. A suitable standard for documenting such evaluations could consist of the Brief ICF-CS for CWP, LBP, and depression or obesity, augmented by additional ICF categories relevant for this particular context. In addition, the unique individual experiences of claimants have to be considered in order to assess work capacity comprehensively.
