Falls rate increase and foot dorsal flexion limitations are exhibited in patients who suffer from asthma: A novel case-control study

Impact of Asthma on Plantar Pressures in a Sample of Adult Patients: A Case-Control Study

Based on the high prevalence of asthma in the population, and its relationship with various musculoskeletal and postural disorders, the aim of this study was to evaluate the plantar pressures in asthmatic patients compared to a control group. A case-control study involving 90 participants was conducted, consisting of 45 asthma patients and 45 healthy paired controls. Static plantar pressure data were recorded using a portable pressure sensor platform. Statistically significant differences were shown in the body weight on the left heel (p = 0.031), and the right forefoot maximum peak pressure was lower in the case group (p = 0.042). The findings of this study show alterations in static plantar pressures in asthmatic patients compared to healthy individuals. Specifically, the subjects with asthma showed less maximum pressure in the right forefoot and less weight on the left heel, which appear to be associated with the asthma disease.

Assessment of Selected Spatio-Temporal Gait Parameters on Subjects with Pronated Foot Posture on the Basis of Measurements Using OptoGait. A Case-Control Study

Walking is part of daily life and in asymptomatic subjects it is relatively easy. The physiology of walking is complex and when this complex control system fails, the risk of falls increases. As a result, gait disorders have a major impact on the older adult population and have increased in frequency as a result of population aging. Therefore, the OptoGait sensor is intended to identify gait imbalances in pronating feet to try to prevent falling and injury by compensating for it with treatments that normalize such alteration. This study is intended to assess whether spatiotemporal alterations occur in the gait cycle in a young pronating population (cases) compared to a control group (non-pronating patients) analyzed with OptoGait. Method: a total of n = 142 participants consisting of n = 70 cases (pronators) and n = 72 healthy controls were studied by means of a 30 s treadmill program with a system of 96 OptoGait LED sensors. Results: Significant differences were found between the two groups and both feet in stride length and stride time, gait cycle duration and gait cadence (in all cases p < 0.05). Conclusions: pronating foot posture alters normal gait patterns measured by OptoGait; this finding presents imbalance in gait as an underlying factor. Prevention of this alteration could be considered in relation to its relationship to the risk of falling in future investigations.

The effect of pain severity on balance, postural stability and fall risk in patients with shoulder pathologies

INTRODUCTION

The study aimed to investigate how pain severity in the shoulder region affects balance ability, postural stability and fall risk.

MATERIAL AND METHODS

Sixty participants with shoulder pain, aged 42.45 ±6.51 years, were assessed using a Visual Analog Scale (VAS); they were divided into 2 subgroups as a mild pain group (group 1) and a moderate/severe pain group (group 2). According to VAS-at rest the mild-pain group included 39 and the moderate/severe-pain group included 21 subjects. According to VAS-during movement, the mild-pain group included 19 and the moderate/severe-pain group included 41 subjects. Balance ability-postural stability, fall risk and fear of falling were assessed by the Sportkat System, Berg Balance Scale (BBS), and Fall Efficacy scale (FES) respectively. Differences of variables between mild pain and moderate/severe pain groups were analyzed by the independent groups t-test in groups conforming to a normal distribution and the Mann-Whitney U test for the variables that did not fit a normal distribution.

RESULTS

A positive relationship was found between VAS-at rest and double-foot static balance test score right-left (RL) ratio, while a negative relationship was found between VAS-at rest and BBS score (p < 0.05). Significant differences were found between right foot static balance left score and RL ratio according to pain at rest (p < 0.05).

CONCLUSIONS

The results indicated that shoulder pain severity affects balance parameters. As pain level at rest increases, postural sway increases in a medio-lateral direction, and towards the left while standing on the right foot. Approaches regarding increasing balance and postural instability should be included in physiotherapy and rehabilitation programs of patients with shoulder pain at an early phase to protect patients from balance problems and fall risk.

Pulmonary Rehabilitation is Improved by In-Shoe Foot Orthosis Intervention

Some studies have found that patients with asthma have bilateral foot dorsal flexion limitations, contributing to impaired quality of life. The authors hypothesised that foot misalignments could also occur in patients with chronic obstructive pulmonary disease (COPD), and that foot orthoses could increase the motor benefits of their pulmonary rehabilitation (PR). Presented herein are the results from a nonrandomised controlled study in 40 patients with COPD. Twenty patients had foot misalignment (Group 1) and wore foot orthoses for a 1-month PR period. Their data were compared to those obtained in 20 other patients with COPD who had no foot misalignment and did not wear foot orthoses (Group 2). Bodily fatigue, 6-minute walk test (6MWT) distance, peak plantar flexion force (PFF), and oscillations of the centre of pressure (CoP) were measured. Measurements were performed prior to and following completion of PR (Groups 1 and 2), immediately after wearing the foot orthosis (Group 1), and after completion of PR plus foot orthoses (Group 1). In Group 2, PR increased the 6MWT distance, but did not increase PFF nor reduce CoP oscillations and fatigue scale. Wearing the foot orthosis for the first time significantly increased the 6MWT distance (+98+12 m). Following PR with foot orthoses (Group 1), a further increase in 6MWT distance occurred (+120+13 m), bodily fatigue was reduced, PFF increased, and CoP oscillations decreased. In patients with COPD and foot misalignment, foot orthoses enhanced the functional capacity and improved the postural control.
