“…All participants were right hand dominant, suggesting that reaching dominance might play a role in offloading. Our findings are in agreement with Grangeon et al 28 who suggested that individuals with SCI may prefer to reach with their dominant limb, and while reaching, use their non-dominant limb for support. Consequently, individuals with SCI may prefer to reach towards their dominant side when engaging in daily activities, 9 thereby offloading their non-dominant side making it plausible that non-dominant limb support also relates to side offloading.…”

“…Fourteen of our 16 wheelchair users were right handed suggesting that, it may be possible to explore the interaction of trunk postural control, limb dominance, intensity of use, and reach distance during recovery and rehabilitation, particularly for those who will be required to reach from the sitting position for future activities if they do not recover the ability to walk. Grangeon et al 25 suggest that individuals with SCI may use their dominant upper extremity for reaching more frequently while providing support through their non-dominant limb, thereby developing superior seated stability with their dominant limb elevated. Our study demonstrated that the changes in strength of the less affected hip and left trunk flexion strength were related to changes in right MDRT distance while the corresponding value of trunk extension strength was related to left MDRT distance.…”

Context: Trunk control is essential to engage in activities of daily living. Measuring trunk strength and function in persons with spinal cord injury (SCI) is difficult. Trunk function has not been studied in non-traumatic SCI (NTSCI). Objectives: To characterize changes in trunk strength and seated functional reach in individuals with NTSCI during inpatient rehabilitation. To determine if trunk strength and seated reach differ between walkers and wheelchair users. To explore relationships between trunk and hip strength and seated functional reach. Design: Observational study. Setting: Two SCI rehabilitation facilities. Participants: 32 subacute inpatients (mean age 48.0 ± 15.4 years). Outcome measures: Isometric strength of trunk and hip and function (Multidirectional Reach Test: MDRT) were assessed at admission and within 2 weeks of discharge. Analysis of variance was conducted for admission measures (MDRT, hip and trunk strength) between walkers and wheelchair users. Changes in MDRT, hip and trunk strength were evaluated using parametric and non-parametric statistics. The level of association between changes in values of MRDT and strength was also examined. Results: Significant differences between walkers and wheelchair users were found for strength measures (P < 0.05) but not for MDRT. Left-and right-sided reaches increased in wheelchair users only (P < 0.05). Associations between changes in hip strength, trunk strength, and reach distance were found (R = 0.67-0.73). Conclusion: In clinical settings, it is feasible and relevant to assess trunk, hip strength, and MRDT. Future studies require strategies to increase the number of participants assessed, in order to inform clinicians about relevant rehabilitation interventions.

“…Previous studies showed that individuals with the most long-lasting SCI tended to exhibit increased control demand on the AP directional component with no altered effect on stability performance, irrespective of the sitting position. These results suggested a preferential and optimal use of non-postural muscles as a result of time and learning [41]. Based on electromyography studies among individuals with SCI [40], the co-activation of thoracohumeral muscles (e.g., latissimus dorsi and trapezius pars ascendens), the upper thoracic portion of the erector spinae and the scapular protractors (e.g., pectoralis major and serratus anterior) might provide posterior stabilization controlling anterior displacements of the trunk segment [39].…”

The objective of this study was to determine a minimum data set of postural measures to characterize seated stability in individuals with spinal cord injury (SCI) by computing 39 Center-Of-Pressure (COP) measures routinely investigated in standing posture. Two short-sitting positions on an instrumented seat with the feet resting on force plates were compared between 14 individuals with SCI and 14 healthy controls: 1) with both hands on their thighs and 2) with both upper extremities flexed at 70 o and abducted at 45 o . The correlations between all COP measures for the resultant, anteroposterior and mediolateral components were also computed. Differences in seated stability were observed between individuals with SCI and healthy controls, irrespective of the tasks. More precisely, the bilateral hand support was confirmed to be an effective strategy to compensate for anterior instability in individuals with SCI. As anticipated, time domain distance and frequency domain measures revealed complementary information. Distance and area COP measures were highly correlated with each other (i.e., redundant information) but were not correlated with frequency and hybrid measures. For both groups (between-task comparisons), the most discriminative uncorrelated measures were related to frequency parameters (i.e., independent information). Overall, our analyses revealed that a minimal data set of postural measures should include mean distance, mean velocity, centroidal frequency, median power frequency and frequency dispersion. These measures should be reported for all directional components whenever applicable, as both anteroposterior and mediolateral activities independently contribute to the resultant COP outcome measures.
