“…Following hip flexion movement, the activation of EO and RA was within the same time frame (APA2) for both the ipsilateral and the contralateral sides, this is consistent with previous work [13]. However, whilst seated on the ball, the ipsilateral RA and EO were activated to a greater extent than when seated on the chair.…”

“…Taking stroke as an example, studies have found reduced magnitude and delayed anticipatory EMG activity of the superficial postural trunk muscles on the paretic side [11]. This abnormality in APAs was found to be significantly related to deficits in motor and functional abilities [13] and an important predictor of the functional outcome of stroke [13,15]. Training has been suggested as a way of improving APAs in trunk muscles [16], but only one study was found which explored ways of achieving this [17].…”

“…It has been demonstrated that the motor impairment following a stroke is partially due to changes in the anticipatory postural control (Slijper et al, 2002;Dickstein et al, 2004;Silva et al, 2012;Pereira et al, 2014). It should be also noted that trunk control at an early stage post stroke is one of the strongest predictors of upper-limb functional recovery (Hsieh et al, 2002).…”

“…APAs are also influenced by conditions such as Parkinson's disease (Aruin et al 1996), stroke (Dickstein et al 2004), low back injury (Hodges 2001;Hodges et al 2003), and muscle fatigue (Allison and Henry 2002;Strang and Berg 2007;Strang et al 2008;Strang et al 2009). Compared to the role of APAs in self-induced stability perturbations, the role of APAs in externally induced stability perturbations, such as those that potentially occur when catching an object, has received less attention.…”

The effect of load uncertainty on anticipatory muscle activity in catching

To investigate how the CNS copes with load uncertainty in catching, anticipatory postural adjustments (APAs) in one-handed catching of balls of known and unknown weights were compared. Twenty-nine (n = 29) men (mean age = 21.1 years) participated, all of whom had engaged in a sport activity requiring hand-eye coordination. Participants' muscle activity in the biceps brachii, triceps brachii, wrist flexor group, and bilateral erector spinae at L4-5 was recorded using electromyography (EMG) while they caught visually identical balls of four different weights (0.5, 1.33, 2.17, and 3.0 kg). EMG integrals were computed for the 1 s prior to ball drop (pre-drop period), and the interval between ball drop and catch (drop period). Uncertainty about ball weight had no effect on APA activity during the pre-drop period. During the drop period, however, load uncertainty did influence APA activity in the biceps brachii, triceps brachii, and the wrist flexor muscles (i.e., the effect of ball weight on APA magnitude depended on the presence or absence of load knowledge). In the known ball weight condition, participants exhibit greater APA magnitude with increases in ball weight. In contrast, under the unknown ball weight condition, APA magnitude was relatively consistent across ball weights and at a level similar to the APA magnitude for an intermediate weight (i.e., the second heaviest ball of four) in the known weight condition. In catching balls of unknown weights, the CNS appears to scale APA magnitude to afford the greatest chance of catching the ball, regardless of the weight.
