The Impact

Background: Spinal cord injuries (SCI) are a variety of chronic diseases that various causes such as trauma may contribute to its onset. One of the problems in these patients is the problem of physical activity and, consequently, daily activities. Objectives: This study aimed to assess daily living of patients with SCI. Methods: In this descriptive cross-sectional study in 2019, 120 patients with SCI in Kermanshah were included in the study using purposive sampling. The instruments used in this study fell into two parts. One part included the demographic characteristics of the SCI patients, and the other part was a questionnaire of the rate of the Impact on Participation and Autonomy questionnaire (IPA-P). Data were analyzed by SPSS software version 16 using descriptive tests such as mean and standard deviation. Results: The result showed there was a significant relationship between demographic characteristics such as education (P < 0.007), time of spinal cord injury (P < 0.01), and income (P = 0.000). Also, the results showed there was a relationship between Autonomy and Participation, and the age of patients and their autonomy and participation decreased with age (P = 0.000, R = 0.72). Most of the patients had severe problems with daily activities. Also, most patients had very poor scores in relation to daily living activities. Conclusions: Considering the low rate of participation and autonomy in patients with SCI, it is suggested to conduct studies aimed at improving their self-care and social participation.

The Future

Abstract Background: Exoskeleton use by people with complete spinal cord injury (SCI) in daily life is still a challenge. To optimize its daily life use, a better understanding of the purpose of use and the accompanying improvements are needed. The perspective of experienced exoskeleton users provides an important contribution to the improvement of future exoskeletons.Methods: Face-to-face semi-structured interviews were held with 13 people with SCI, who were experienced exoskeleton users. Interviews were audio-taped, transcribed and analysed thematically.Results: Participants expressed three future purposes of exoskeleton use: for daily activities, exercise, and social interaction. Exoskeleton use during daily activities was the ultimate goal. Therefore, the future exoskeleton should be: easy to use, small and lightweight, tailor made, safe, comfortable, less distinctive, durable, and affordable. Improving the ease of use was relevant for all purposes, for all participants. The other suggestions for improvement varied depending on the purpose of use and the participant. Conclusions: Increasingly more advanced improvements to future exoskeletons are needed to transition from an exercise purpose, to social interaction, and ultimately use during daily activities. In the current study, detailed suggestions for improvements from experienced exoskeleton users have been made. Only when multiple of these suggestions are adjusted, can the exoskeleton be used to its full potential.

This study aimed to investigate the validity of using built-in smartphone accelerometers to estimate the active energy expenditures of full-time manual wheelchair users with spinal cord injury (SCI). Twenty participants with complete SCI completed 10 5-min daily activities that involved the upper limbs, during which their oxygen consumption and upper limb activity were registered using a portable gas analyzer and a smartphone (placed on the non-dominant arm), respectively. Time series of 1-min averaged oxygen consumption and 55 accelerometer variables (13 variables for each of the four axes and three additional variables for the correlations between axes) were used to estimate three multiple linear models, using a 10-fold cross-validation method. The results showed that models that included either all variables and models or that only included the linear variables showed comparable performance, with a correlation of 0.72. Slightly worse general performance was demonstrated by the model that only included non-linear variables, although it proved to be more accurate at estimating the energy expenditures (EE) during specific tasks. These results suggest that smartphones could be a promising low-cost alternative to laboratory-grade accelerometers to estimate the energy expenditure of wheelchair users with spinal cord injury during daily activities.

Cord Injury

Spinal cord injury (SCI) can lead to changes in muscle activation patterns and atrophy of affected muscles. Moderate levels of SCI are typically associated with foot drag during the swing phase of locomotion. Foot drag is often used to assess locomotor recovery, but the causes remain unclear. We hypothesized that foot drag results from inappropriate muscle coordination preventing flexion at the stance-to-swing transition. To test this hypothesis and to assess the relative contributions of neural and muscular changes on foot drag, we developed a two-dimensional, one degree of freedom ankle musculoskeletal model with gastrocnemius and tibialis anterior muscles. Anatomical data collected from sham-injured and incomplete SCI (iSCI) female Long-Evans rats as well as physiological data from the literature were used to implement an open-loop muscle dynamics model. Muscle insertion point motion was calculated with imposed ankle trajectories from kinematic analysis of treadmill walking in sham-injured and iSCI animals. Relative gastrocnemius deactivation and tibialis anterior activation onset times were varied within physiologically relevant ranges based on simplified locomotor electromyogram profiles. No-atrophy and moderate muscle atrophy as well as normal and injured muscle activation profiles were also simulated. Positive moments coinciding with the transition from stance to swing phase were defined as foot swing and negative moments as foot drag. Whereas decreases in activation delay caused by delayed gastrocnemius deactivation promote foot drag, all other changes associated with iSCI facilitate foot swing. Our results suggest that even small changes in the ability to precisely deactivate the gastrocnemius could result in foot drag after iSCI.
