“…3,11 This impairment in the ML axis could be a manifestation of altered multijoint coordination between the trunk and lower limbs, which are needed for optimizing postural control. 35 Thus, this result reinforces the need for improving postural control in the ML axis. Also, the value can be used to predict multiple falls in elderly individuals.…”

Introduction: People with haemophilic arthropathy (PWHA) have impairments in postural control. However, little is known about the effects of demanding conditions, including the unipedal stance and dual tasks, on postural control in PWHA. Aim: Determine the effects of performing dual tasks while in the one-leg stance on postural sway and postural control complexity in PWHA vs. healthy active (HAG) and non-active (HNAG) groups of individuals. Methods: Fifteen PWHA and 34 healthy subjects (18 active and 16 non-active) were recruited. Vertical (V), mediolateral (ML) and anteroposterior (AP) centre of mass signals were acquired using a 3-axis accelerometer placed at the L3/L4 vertebrae of subjects as they performed the one-leg stance under single and dual-task conditions. Sway balance and the complexity of postural control were studied via root mean square (RMS) acceleration and sample entropy, respectively. Increased complexity of postural sway was attributed to increased automatism of postural control.Results: RMS values for PWHA were higher than HAG under both conditions for the V and ML axes, and higher than HNAG under the dual-task condition for the ML axis.Sample entropy was lower in PWHA than healthy individuals under the dual-task condition for V and ML axes, and the single-task condition for the ML axis (P < .05). Conclusion:PWHA had poorer postural sway and decreased postural control complexity when performing a one-leg stance than healthy people, especially when the dual-task condition was applied. These results may help to design new approaches to assess and improve postural control in PWHA.

“…This finding could be an expression of lesser hips and trunk control; however, haemophilia patients showed greater joint damage in the knees and ankles . Furthermore, this result could be a manifestation of deficient multijoint coordination between the trunk and lower limbs for optimizing postural control . Moreover, the ACoM in the anteroposterior axis was higher in haemophiliacs in both the open‐ and closed‐eyes conditions, suggesting a diminished capacity of the ankle to maintain the CoM stable…”

“…Together, these measurements could improve on and corroborate the present results. In addition to this, an integral approach with surface electromyography in the lower limbs and trunk could help elucidate the motor strategies used by haemophiliacs during postural tasks . Furthermore, radiological exams such as computed tomography, magnetic resonance imaging and sonography were not used in the current assessments.…”

“…Both legs were tested starting with the dominant one determined as mentioned before. The predominant strategy to maintain postural control up to moderately challenging tasks is the utilization of the ankle, also in seniors (Donath et al, 2016a). Therefore, measurement of ankle strength was chosen in favour of the knee.…”

Background In addition to generally high levels of physical activity, multi-component exercise training is recommended for the maintenance of health and fitness in older adults, including the prevention of falls and frailty. This training often encompasses serial sequencing of balance, strength, endurance and other types of exercise. Exercise training featuring integrative training of these components (i.e. agility training) has been proposed, as it more likely reflects real life challenges like stop-and-go patterns, cutting manoeuvers, turns and decision-making. In this study, we compared the efficacy of an agility-based training to the traditional strength and balance training approach with regard to selected risk factors for falls and frailty. Methods We trained twenty-seven community-dwelling healthy seniors (16♂; 11♀; age: 69.5 ± 5.3 y; BMI: 26.4 ± 3.7 kg/m2) for 8 weeks in a group setting with 3 sessions per week, each lasting 50 minutes. Participants were randomized into either the agility group (AGI; n = 12), that used the integrative multi-component training, or the traditional strength and balance group (TSB; n = 15). TSB performed balance and strength exercises separately, albeit within the same session. The training of both groups progressively increased in difficulty. Outcomes were static and dynamic balance (single leg eyes open stand, Y-balance test, reactive balance), lower limb (plantar flexion and dorsal extension) and trunk flexion and extension maximum strength and rate of torque development (RTD). In addition, we tested endurance by the six-minute walk test (6MWT). We calculated linear mixed effects models for between-groups comparisons as well as effect sizes (ES) with 95 % confidence intervals. Results Small ES in favor of AGI were found for plantar flexion strength (ES > 0.18[−0.27;0.89]) and RTD (ES > 0.43[−0.19;1.36]) as well as trunk extension RTD (ES = 0.35[−0.05;0.75]). No other parameters showed notable between group differences. Compliance was high in both groups (AGI: 90 ± 8% of sessions; TSB: 91 ± 7% of sessions). Discussion Agility-based exercise training seems at least as efficacious as traditional strength and balance training in affecting selected physical performance indicators among community-dwelling healthy seniors. In particular, lower limb and trunk extension explosive strength seem to benefit from the agility training.
