Propensity for conscious control of movement is unrelated to asymptomatic hypermobility or injury-risk scores

The Movement Specific Reinvestment Scale (MSRS) measures the propensity for conscious monitoring and control of movement, which can inhibit automated movement processes, potentially causing movement disruption or injury. High injury risk individuals are more likely to make movement errors during jump-landing tasks, and hypermobile individuals present with poor movement control. The link between MSRS and these characteristics remains largely unexplored. Consequently, we examined propensity for movement specific reinvestment in high injury risk and asymptomatic hypermobile participants. Sixty volunteers (35 males, 25 females) were tested using the MSRS, Landing Error Scoring System (LESS), and Beighton hypermobility scale. Spearman rank correlation coefficients were computed between MSRS, LESS, and Beighton scores. Furthermore, MSRS scores were compared between low (LESS < 5 errors) and high (LESS ≥ 5 errors) injury risk, as well as non-hypermobile and hypermobile participants. MSRS scores were not significantly related to LESS (ρ = 0.06, p = 0.625) or Beighton (ρ = 0.09, p = 0.481) scores. MSRS scores of low and high injury risk (37.8 ± 7.8 vs 38.0 ± 8.6, p = 0.933), and non-hypermobile and hypermobile (37.5 ± 8.9 vs 39.0 ± 7.0, p = 0.524) participants were comparable. Based on our results, there is no evidence that movement specific reinvestment contributes to injury risk assessed by LESS, which might be due to the phylogenetic nature of the LESS jump-landing task and/or the low psychological pressure environment of laboratory testing. The propensity for movement specific reinvestment did not vary in asymptomatic hypermobile individuals compared to non-hypermobile individuals; however, examination of the MSRS in symptomatic hypermobile individuals and individuals with well-defined syndromes is needed to fully elucidate whether or not conscious monitoring and control of movement plays a role in injury risk or movement control across the hypermobility spectrum.
