“…The finding of decreased COP displacement in the M-L direction during external ankle support is comparable a previous finding that M-L postural sway was reduced when normal subjects performed a single leg stance with a semirigid, stirrup-type brace 42) . Those subjects showed increased postural control, which was manifested as a decrease in the amplitude of postural sway when compared to the no ankle external support condition.…”

Abstract.[Purpose] The purpose of this study was to examine the center of pressure (COP) trajectory variables while initiating gait under three different ankle support conditions: no external ankle support, ankle taping, and the use of a lace-up ankle brace.[Subjects] The study subjects were 7 healthy males (mean [SD] [Methods] Subjects stood in a predetermined position on the floor in front of a force platform and then initiated gait on the force platform at a self-paced speed under the conditions of no external ankle support, ankle taping, and lace-up ankle brace. Changes in the COP trajectories were compared among the three test conditions using one-way repeated analysis of variance.[Results] The ankle external support devices, ankle taping and the lace-up ankle brace, significantly decreased the COP displacement in the mediolateral direction as compared to the no external support condition. However, there were no significant differences in the COP displacement in the anteroposterior direction, the average COP velocity, and the total length of the COP path among the three test conditions. [Conclusion] Intervention using a prophylactic ankle support device appears to be an effective means of reducing injuries because it provides increased mechanical stability.

“…Whereas in older people and those with disabilities JPS plays a greater role. Evidence is available about the immediate effects of an appliance providing compression at the ankle on JPS and balance [9][10][11][12][13]. However, these studies were on healthy young people or young athletes with ankle instability.…”

“…The application of ankle foot orthoses (AFOs) and compression of the ankle and foot have been shown to have an association with improvement of ankle JPS [9][10][11][12][13][14][15]. Due to compression, additional feedback from mechanoreceptors in the skin could contribute to the improvement in JPS.…”

“…This is not only limited to vigourous activity, but occurs in daily activities such as walking. There is a large body of literature in which the effects of various prophylactic ankle supports on variables such as ankle range of motion [2], ankle muscle strength [4,24], reflex and voluntary reaction time [13,19], postural steadiness [5,9] and functional performance tasks [7] have been reported. Normal foot biomechanics during the stance phase has been thoroughly studied [8].…”

We performed a gait analysis of 12 healthy subjects in order to analyse the rear foot pronation-supination angle and the shift of centre of pressure (COP) during walking. We used a video system and a force plate and examined the effects of semi-rigid Air-Stirrup brace, lace-up cloth RocketSoc brace, ankle taping and no bracing. Both the lace-up cloth brace and taping increased the maximum pronation angle during the stance phase. The lace-up cloth brace alone was associated with a larger maximum pronation velocity. With the lace-up cloth brace and taping, the COP was more laterally placed, allowing greater leverage about the subtalar axis and thus increasing the tendency toward pronation. The two braces and the tape did not similarly affect ankle joint biomechanics during gait. The ability to reduce excessive amounts of pronation is an important design consideration for prophylactic ankle supports.
