“…Of note, this approach was done to establish specific within-modality information only. ES were interpreted as follows: small = 0.14, moderate = 0.31, large = 0.61 based on empirical data from 99 meta-analyses examining the effects of rehabilitation/exercise 41 . Statistical heterogeneity was quantified using Higgins' I 2 statistic, and was interpreted as follows: heterogeneity: > 50%, no or limited heterogeneity: < 50% 42 .…”

“…While NHST statistics is about statistical significance, effect size statistic talks about the practical importance of studies' results. Effect size indices are widely interpreted in terms of "small," "medium," or "large" for application purposes (García, 2017;Kinney et al, 2020).…”

Social sciences research (SSR) is an enterprise that is continuously evolving, but not without some debilitating issues that impede the realization of its full potential and usefulness. SSR, as a human initiative and activity, is discussed. The paper features the current methods and authorship issues that enhance the research outcomes' validity. The argument advanced because while scholars continue to explore processes for research advancement, minimize where possible by putting an end to vices such as falsification, plagiarism, inappropriate methodology, and wrong data analysis. At the same time, while significant challenges are related to misconduct and dishonesty. The present paper expanded and updated the literature and proposed bringing the resources available to the social science researchers to enhance research outcomes. Overall, the paper recommends continuous strives for tools, and process enhancement and a demonstration of integrity by the stakeholders in SSR conduct to achieve field acceptance.

“…We computed the effect size using Hedges' g, as this approach is recommended for small samples [38]. Effect sizes were interpreted per recommendations for rehabilitation studies as small effects: 0.08 to 0.15, medium effects: 0.19 to 0.36, and large effects: 0.41 to 0.67 [40].…”

Locomotor training (LT) is intended to improve walking function and can also reduce spasticity in motor-incomplete spinal cord injury (MISCI). Transcutaneous spinal stimulation (TSS) also influences these outcomes. We assessed feasibility and preliminary efficacy of combined LT + TSS during inpatient rehabilitation in a randomized, sham-controlled, pragmatic study. Eighteen individuals with subacute MISCI (2–6 months post-SCI) were enrolled and randomly assigned to the LT + TSS or the LT + TSSsham intervention group. Participants completed a 4-week program consisting of a 2-week wash-in period (LT only) then a 2-week intervention period (LT + TSS or LT + TSSsham). Before and after each 2-week period, walking (10 m walk test, 2-min walk test, step length asymmetry) and spasticity (pendulum test, clonus drop test, modified spinal cord injury—spasticity evaluation tool) were assessed. Sixteen participants completed the study. Both groups improved in walking speed and distance. While there were no significant between-groups differences, the LT + TSS group had significant improvements in walking outcomes following the intervention period; conversely, improvements in the LT + TSSsham group were not significant. Neither group had significant changes in spasticity, and the large amount of variability in spasticity may have obscured ability to observe change in these measures. TSS is a feasible adjunct to LT in the subacute stage of SCI and may have potential to augment training-related improvements in walking outcomes.
