Abstract
[Purpose] In sports physical therapy, video of a patient’s movement or of a skilled
model’s movement has been used as observational learning methods for injury prevention and
movement modification. Positive effects of model video observation have been reported.
This study aimed to clarify the effect on motor skill learning using a combination of
model-observation and self-observation, which is thought to act as an enhanced method for
active error detection by comparing model-observation and self-observation alone for
acquisition of correct sports movement. [Subjects and Methods] Forty-five healthy females
were randomly allocated into three groups comprising model- and self-observation,
model-observation, and self-observation. The motor task performed was a half golf swing
using an elastic club. Shoulder grip angle between both shoulder lines and the acromia
grip strength were measured as an index of body rotation using a three-dimensional motion
analyzer. Change in the shoulder grip angle in the three groups was analyzed at pre-,
immediate delayed retention, and delayed retention tests. [Results] A significant
difference in shoulder grip angle was observed among the three groups for the immediate
delayed retention test. The combined model and self-observation group had a value closer
to 90 degrees compared to the other two groups. [Conclusion] Observation combining model
and self-observation exerted a positive effect on short-term motor skill learning.

Educational impact of a clinical anatomy workshop on 1st-year orthopedic and rheumatology fellows in Mexico City. Clin Rheumatol 2015; 35:1299-306. [PMID: 26400643 DOI: 10.1007/s10067-015-3076-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2015] [Revised: 09/06/2015] [Accepted: 09/08/2015] [Indexed: 12/26/2022]
Abstract
We aim to study the educational impact of a clinical anatomy workshop in 1st-year orthopedic and rheumatology fellows. First-year rheumatology fellows (N = 17) and a convenience sample of 1st-year orthopedic fellows (N = 14) from Mexico City in the 9th month of training participated in the study. The pre- and the post- workshop tests included the same 20 questions that had to be answered by identification or demonstration of relevant anatomical items. The questions, arranged by anatomical regions, were asked in five dynamic stations. Overall, the 31 participants showed an increase of correct answers, from a median of 6 (range 1 to 12) in the pre-workshop test, to a median of 14 (range 7 to 19) in the post-workshop test. In the pre-workshop test, the correct median answers were 7 (range 2 to 12) in the orthopedic fellows and 5 (range 1 to 10) in the rheumatology fellows (p = 0.297). Corresponding scores in the post-workshop were 15 (range 10 to 19) and 12 (range 7 to 18) (p = 0.026) showing a significant difference favoring the orthopedic group. Our clinical anatomy workshop was efficacious, in the short term, as a teaching instrument for 1st-year orthopedic and rheumatology fellows. The post-workshop scores, although significantly improved in both groups, particularly in the orthopedic fellows, were still suboptimal. Further refinements of our workshop might yield better results.

Human adipose-derived stem cells accelerate the restoration of tensile strength of tendon and alleviate the progression of rotator cuff injury in a rat model. Cell Transplant 2015; 24:509-20.

Abstract
Adult stem cell therapy for the treatment of tendon injuries is a growing area of research. This study is aimed to investigate the efficacy of human adipose-derived stem cell (hADSC) injection on the tendon during its healing process in a rat model of rotator cuff injury. hADSCs were injected 3 days after collagenase-induced rotator cuff injuries in experimental groups, while the control group received saline as a placebo. Histological and biomechanical analyses were performed 7, 14, 21, and 28 days after collagenase injection. Compared to the control group, it was found that inflammatory cells were significantly decreased in the hADSC-treated group after collagenase injection for 7 and 14 days. In the hADSC-injected group, the fiber arrangement and tendon organization had also been improved. On the seventh day after collagenase injection, the load to failure of the hADSC-injected group (15.87 ± 2.20 N) was notably higher than that of the saline-injected group (11.20 ± 1.35 N). It is suggested that the tensile strength of the supraspinatus tendon was significantly enhanced. Local administration of hADSCs might have the possibility to restore the tensile strength and attenuate the progression of tendinitis. Taken together, these findings demonstrate that the recovery processes in damaged tendons can be facilitated architecturally and functionally after hADSC injection.

Self-assessed efficacy of a clinical musculoskeletal anatomy workshop: A preliminary survey. ACTA ACUST UNITED AC 2014; 11:224-6. [PMID: 25544712 DOI: 10.1016/j.reuma.2014.11.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Revised: 08/11/2014] [Accepted: 11/09/2014] [Indexed: 10/24/2022]
Abstract
OBJECTIVE To survey the efficacy of a practical workshop on clinical musculoskeletal anatomy held in five American countries. METHODS A self-assessment competence questionnaire sent to participants 1-3 months after the workshop. Results were compared to the results of a practical, instructor-assessed, pre-workshop test. RESULTS The response rate of participants was 76.4%. The overall, self-assessed competence score for anatomical items that had been included in the pre-test was 76.9 (scale 0-100) as compared to an overall score of 48.1 in the practical, pre-workshop test (p<0.001). For items that were addressed in the workshop, but not included in the pre-test, self-assessed competence was rated at 62.9. Differences in anatomical knowledge between individuals from different countries and professional groups noted in the practical pre-test were no longer present in the post-test self-assessment. CONCLUSIONS From this preliminary data and supporting evidence from the literature we believe that our anatomy workshop provides an effective didactic tool for increasing competence in musculoskeletal anatomy.

Preworkshop knowledge of musculoskeletal anatomy of rheumatology fellows and rheumatologists of seven North, Central, and South American countries. Arthritis Care Res (Hoboken) 2014; 66:270-6.

Abstract
OBJECTIVE To report the baseline knowledge of clinical anatomy of rheumatology fellows and rheumatologists from Argentina, Chile, Ecuador, El Salvador, Mexico, the US, and Uruguay. METHODS The invitation to attend a workshop in clinical anatomy was an open call by national rheumatology societies in 4 countries or by invitation from teaching program directors in 3 countries. Prior to the workshop, a practical test of anatomic structures commonly involved in rheumatic diseases was administered. The test consisted of the demonstration of these structures or their function in the participant's or instructor's body. At one site, a postworkshop practical test was administered immediately after the workshop. RESULTS There were 170 participants (84 rheumatology fellows, 61 rheumatologists, and 25 nonrheumatologists). The overall mean ± SD number of correct answers was 46.6% ± 19.9% and ranged from 32.5-67.0% by country. Rheumatology fellows scored significantly higher than nonrheumatologists. Questions related to anatomy of the hand scored the lowest of the regions surveyed. CONCLUSION Rheumatology fellows and rheumatologists showed a deficit in knowledge of musculoskeletal anatomy that is of central importance in rheumatologic assessment and diagnosis. This gap may hinder accurate and cost-effective rheumatologic diagnosis, particularly in the area of regional pain syndromes. Presently, widespread use of musculoskeletal ultrasound (MSUS) by rheumatologists may be premature, since a key component of expert-level MSUS is the integration of an accurate knowledge of anatomy with the views obtained with the ultrasound probe.
