Special Issue Information

Dear Colleagues,

From a child learning to throw a ball to a stroke patient demonstrating again the capacity to walk independently, the complexity of change in motor behavior cannot be overstated. Unfortunately, the richness and difficulty of understanding how the many degrees-of-freedom of our motor system change towards states of more functionality and complexity have been neglected. Either because of the belief that simplistic experiments could grasp essential aspects or to emphasize other levels of analyses (brain imaging). Currently, the field has recognized the need to understand the dynamics of change through the integration of different areas of knowledge that characterize behavior at the right level of analysis. The present Special Issue will present new perspectives and evidence on how humans deal with the problems of many degrees of freedom in motor learning.

We invite papers on the topics of:

  • Motor Learning;
  • Motor Development;
  • Rehabilitation;
  • Sport Sciences;
  • Aging.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The validity and reliability of the Lower Extremity Motor Coordination Test (LEMOCOT) were assessed in patients with multiple sclerosis (MS). The study involved 60 participants diagnosed with MS (mean age: 48.13 years, range: 24–80 years). Intra-rater reliability was assessed within-day (n = 12), and inter-rater reliability was assessed within-day (n = 45) and between-days (n = 22). For known-groups validity, test scores were compared between participants of different sexes; for convergent validity, test scores were correlated with age, the Five-Repetition Sit-to-Stand test (FSTS), the Berg Balance Scale (BBS), the Lower Extremity Functional Scale (LEFS), and the Expanded Disability Status Scale (EDSS). To test the discriminant validity, the LEMOCOT test scores were correlated with the Mini-Mental State Evaluation (MMSE) and compared according to social history (living alone or not). The LEMOCOT test was tested under three different conditions and found to be very reliable (intraclass correlation coefficient, ICC2,1 > 0.94) with an acceptable error level (standard error of the measurement, SEM, between 1.39 and 3.47 targets and 95% minimum detectable change; MDC95%, between 3.84 and 9.58 targets). Convergent validity was verified, as the LEMOCOT registered very strong correlations with the FSTS test (r = −0.851) and the BBS scale (r = 0.815), a strong correlation with the LEFS scale (r = 0.78), a moderate correlation with the EDSS scale (r = −0.634), all highly significant (p < 0.001), and a weak correlation with age (r = −0.332, p < 0.01). Discriminant validity was also confirmed, as the LEMOCOT demonstrated a weak correlation with the MMSE scale (r = 0.365, p = 0.017) and no differences relative to living environment or sex. The LEMOCOT demonstrated excellent reliability and validity for patients with MS. Full article
