Orthotic Comfort Is Related to Kinematics, Kinetics, and EMG in Recreational Runners

Abstract

In general, comfort is an important and relevant feature of foot orthoses. Evaluations of foot orthoses using comfort do not only reflect subjective perceptions but also differences in functional biomechanical variables. Future research should focus on defining the relationship between comfort and biomechanical variables for material modifications of footwear, different modes of locomotion, and the general population.

Does skate sharpening affect individual skating performance in an agility course in ice hockey?

“…However, the players' subjective feeling of comfort seems to be a better indicator of the actual performance than the subjective performance rating. This notion is supported by earlier findings suggesting that the subjective feeling of comfort is a significant biomechanical variable [9][10][11].…”

Reducing Impact Loading During Running With the Use of Real-Time Visual Feedback

“…6,27 Similarly, the use of shock-absorbing insoles or orthoses has been found to reduce PPA, IP, ALR, and ILR by as much as 16%, 10%, 18%, and 23%, respectively. 14,32,33 Although the reductions in PPA, IP, ALR, and ILR through the use of shoes or orthoses were significant, subjects 1, 2, and 3 achieved larger reductions through the use of real-time visual feedback of tibial acceleration (TaBle). In addition, subjects 1 and 2 had reductions in PPA (FiGUre 3) that brought their PPA values within the normal range of PPA, which is roughly 3 to 8 g. 10,16,23,30 For subjects 4 and 5, their PPA values remained above 8 g (FiGUre 3), and they did not achieve the same reductions in IP, ALR, and ILR as the other subjects (TaBle).…”

Muscle-Activation Onset Times With Shoes and Foot Orthoses in Participants With Chronic Ankle Instability

“…This difference can be considered clinically relevant 35 and may be important because orthotic comfort has been related to muscle activation. 36 The lower hardness level of the custom foot orthoses may further explain this observation, given that softer foot orthoses generally are considered to be more comfortable. 20 …”
