Abstract

To study the influence of Latin dance and Tai Chi on knee joint proprioception and balance. Method: All experiments were performed in the Beijing Normal University School of Physical Education and Sport Biomechanics Laboratory. An isokinetic test system (Biodex system 4, BS4) and a balance testing system (Biodex Balance System, BBS)from the United States Biodex medical system were used to test related indexes. Results: In the LOS test, the overall score of Latin group is much better than sedentary group. In the ASL test, Latin group have a better balance ability in anterior and posterior direction and overall score than sedentary group(p<0.05); TAI CHI group have a better balance ability than sedentary group in anterior and posterior direction(p<0.05)and right and left direction (p<0.01). When the knee joint was at 15, 30, and 45degree positions, the Tai Chi exercise group was much better than sedentary group (P < 0.05), and the 45 degree position in the Tai Chi group was much better than that in the Latin dance group (P < 0.01).When the knee joint was at the 30 degree position, the quadriceps force sense was significantly better in the Tai Chi group than in the Latin dance and sedentary groups. In a test of the four angles, the hamstring force sense in the Tai Chi exercise group was obviously better than that in the sedentary group (P < 0.05); at the 15 degree position, the Tai Chi group was significantly better than the Latin group (P < 0.05); and at 30 degree position, the hamstring force sense of the Latin group was obviously better than that of the sedentary group (P < 0.05).

The commenter has declared there is no conflict of interests.
Comment: I teach medical tai chi research methodologies at Stanford.

This is a methodologically weak study.

Tai chi style, movements not stated.
Latin dance style, movements not stated.
Retrospective, non-interventional, non-randomized.
Poor English, especially in statements of statistical significance of findings.

Conclusion about falls completely ungrounded--incidence of falls wasn't measured.

Interesting research question.
Needs to be repeated as an RCT with well-described interventions and better scientific English.
