“…In studies that investigated more than two treatments (e.g., compression socks and normal socks), the calculated effect size of the multiple treatments was combined and treated as a single effect size for each continuous outcome [51]. Five studies from WGSS [23,24,27,28,52], four studies from TMSS [7,53–55], and three studies from SRSS [33,39,56] had more than two treatments in the experimental design. All the effect sizes of the outcomes were then combined as a single effect size for each study.…”

Systematic reviews of balance control have tended to only focus on the effects of single lower-limb stimulation strategies, and a current limitation is the lack of comparison between different relevant stimulation strategies. The aim of this systematic review and meta-analysis was to examine evidence of effects of different lower-limb sensory stimulation strategies on postural regulation and stability. Moderate- to high- pooled effect sizes (Unbiased (Hedges’ g) standardized mean differences (SMD) = 0.31–0.66) were observed with the addition of noise in a Stochastic Resonance Stimulation Strategy (SRSS), in three populations (i.e., healthy young adults, older adults, and individuals with lower-limb injuries), and under different task constraints (i.e., unipedal, bipedal, and eyes open). A Textured Material Stimulation Strategy (TMSS) enhanced postural control in the most challenging condition—eyes-closed on a stable surface (SMD = 0.61), and in older adults (SMD = 0.30). The Wearable Garments Stimulation Strategy (WGSS) showed no or adverse effects (SMD = -0.68–0.05) under all task constraints and in all populations, except in individuals with lower-limb injuries (SMD = 0.20). Results of our systematic review and meta-analysis revealed that future research could consider combining two or more stimulation strategies in intervention treatments for postural regulation and balance problems, depending on individual needs.

“…For example, PC during quiet standing has been routinely used for many years [25,20,33,34,36], with variations including: standing with bare feet [25]; with shoes on [8,4,29]; with eyes open or closed [25,24]; and with legs spaced a fixed distance and arms crossed on chest [17]. PC during quiet stance has also been evaluated over different trial durations ranging from 30 -120 seconds [33].…”

“…Participants were instructed to start from a standing position, with their feet positioned within the boundaries of a predefined area (400 mm wide × 600 mm long), to place the hands by their sides [29], and to maintain an upright standing position for 2 minutes while looking straight ahead. Similar to previous studies, participants wore their shoes during the test with no restriction with regard to foot placement [24].…”

Impaired postural control (PC) is an important feature of Parkinson's disease (PD) but optimal testing protocols are yet to be established. Accelerometer-based monitors provide objective measures of PC.We characterised time-dependent changes in PC in people with PD and controls during standing, and identified outcomes most sensitive to pathology. Thirty-one controls and 26 PD patients were recruited: PC was measured with an accelerometer on the lower back for 2 minutes (mins).Preliminary analysis (autocorrelation) showed 2 seconds (s) was the shortest duration sensitive to changes in the signal; time series analysis of a range of PC outcomes was undertaken using consecutive 2s windows over the test. Piecewise linear regression was used to fit the time series data during the first 30s and the subsequent 90s of the trial.PC outcomes changed over the 2mins, with the greatest change observed during the first 30s after which PC stabilised. Changes in PC were reduced in PD compared to controls, and Jerk was found to be discriminative of pathology.Previous studies focusing on average performance over the duration of a test may miss timedependent differences. Evaluation of time-dependent change may provide useful insights into PC in PD and effectiveness of intervention.

“…14 Other studies have shown that vibration devices and textured insoles were effective in improving postural instability in patients with PD. 10 Altogether, we consider that the foot position changed by a lateral wedge may alter compensatory muscle activation and proprioceptive properties.…”

“…COP data recorded at 1,000 Hz were measured for 30 s during quiet standing. 1,10 The primary endpoint is to compare the range and velocity of COP between standing with and without the wedge. The secondary endpoint is to compare the same parameters when a patient's eyes were closed.…”

Background:Although postural instability is one of the major symptoms of Parkinson's disease (PD), dopaminergic treatment is ineffective for treating postural instability. Recent reports have shown that somatosensory deficit is associated with postural instability, and that somatosensory input improved postural instability. The purpose of this study is to evaluate the effects of lateral wedges for quiet standing postural control in people with PD. Methods: Twenty-two patients who were diagnosed with PD were enrolled in this study. The participants stood on a force plate under two conditions (wedge and no wedge) with or without having their eyes open or closed. The center of pressure (COP) range and velocity were analyzed using a two-way repeated-measures analysis of variance. Results: The range and velocity of COP in the anterioposterior and mediolateral (ML) directions were significantly improved after the patients stood on the lateral wedge with their eyes closed (p < 0.05). The range in ML direction and velocity in both directions of COP were significantly decreased when their eyes were open (p < 0.05). Conclusions: Regardless of vision, standing on lateral wedges improved postural sway in people with PD. Key words:Parkinson's disease; Rehabilitation; Posture INTRODUCTIONPostural instability is a common and major characteristic of Parkinson' disease (PD). People with postural instability are at risk of losing their abilities to live independently, and to walk; further, these symptoms can affect their quality of life as the disease progresses.1 Previous studies have shown that people with PD display increased postural sway and impairment in mediolateral postural stability compared with elderly people who do not have PD. MATERIALS AND METHODS Study participantsTwenty-two patients who were clinically diagnosed with PD were recruited for this study. The sample size was set based on a previous study. 7Inclusion criteria were as follows: (1) patients clinically diagnosed with PD 8 ; (2) patients who suffer from gait disturbance, including tremor-dominant and PIGD (postural instability and gait disturbance) type; (3) patients between the ages of 50 and 80. The exclusionary criteria were as follows:(1) patients with severe disability above 4 on the Hoehn and Yahr staging scale; and (2) patients with orthopedic problems and other neurological diseases that affect balance control. Clinical assessmentBasic demographic factors, including disease duration, were obtained from interviews with participants. The modified Hoehn and Yahr scale and part III of the Unified Parkinson's Disease Rating Scale (UPDRS) were used for estimating disease severity and motor function. All participants underwent a procedure of taking dopaminergic medicine that was clinically in the "on" state which was taking medicine. We calculated the levodopa equivalence dosage for dopaminergic treatment. All study procedures were approved by the Human Research Ethics Committee of the Inje University Haeundae Paik Hospital, and the participants signed a ...
