“…As such, this stimulus appeared to be unpredictable to the test subject. We applied two peak angular displacements (stimulus amplitude: 0.5° and 1° peak-to-peak) and analyzed PHASE is related to the relative timing between postural reaction and stimulus (54).…”

Background Postural instability presents a common and disabling consequence of chemotherapy-induced peripheral neuropathy (CIPN). However, knowledge about postural behavior of CIPN patients is sparse. With this pilot study, we used a new approach to i) characterize postural impairments as compared to healthy subjects, ii) allocate possible abnormalities to a set of parameters describing sensorimotor function, and iii) evaluate the effects of a balance-based exercise intervention. Methods We analyzed spontaneous and externally perturbed postural control in eight CIPN patients before and after a balance-based exercise intervention by using a modification of an established postural control model. These findings were compared to 15 matched healthy subjects. Results Spontaneous sway amplitude and velocity were larger in CIPN patients compared to healthy subjects. CIPN patients’ reactions to external perturbations were smaller compared to healthy subjects, indicating that patients favor vestibular over proprioceptive sensory information. The balance-based exercise intervention up-weighted proprioceptive information in patients. Conclusions CIPN patients’ major postural deficit may relate to underuse of proprioceptive information that results in a less accurate posture control as spontaneous sway results indicate. The balance-based exercise intervention is able to partially correct for this abnormality. Our study contributes to a better understanding of postural impairments in CIPN patients and suggests an effective treatment strategy.

“…Therefore, we used these model-based measures to prevent misinterpretation of simple postural sway measures like RMS [37,64]. The model-based measures are sensitive enough to detect improvements after a balance-training program [36,37].…”

“…The framework was based on general postural sway measures which in turn, were earlier shown to be sensitive to different types of training programs [23]. Moreover, the framework showed to be sufficiently sensitive to balance-training programs [36,37], and as such paved the path for the future studies of postural control learning dynamics, using unidimensional and meaningful assessment measures.…”

Background: Balance training improves postural control in Parkinson’s disease (PD). However, a systematic approach for the development of individualized, optimal training programs is still lacking, as the learning dynamics of the postural control in PD, over a training program are poorly understood. Objectives: We investigated the learning dynamics of the postural control in PD, during a balance-training program, in terms of the clinical, posturographic, and novel model-based measures. Methods: Twenty patients with PD participated in a balance-training program, 3 days a week, for 6 weeks. Clinical tests assessed functional balance and mobility pre-training, mid-training, and post-training. Center-of-pressure (COP) was recorded at four time-points during the training (pre-, week 2, week 4, and post-training). COP was used to calculate the sway measures and to identify the parameters of a patient-specific postural control model, at each time-point. The posturographic and model-based measures constituted the two sets of stability- and flexibility-related measures. Results: Mobility- and flexibility-related measures showed a continuous improvement during the balance-training program. In particular, mobility improved at mid-training and continued to improve to the end of the training, whereas flexibility-related measures reached significance only at the end. The progression in the balance- and stability-related measures was characterized by early improvements over the first three to four weeks of training, and reached a plateau for the rest of the training. Conclusions: The progression in balance and postural stability is achieved earlier and susceptible to plateau out, while mobility and flexibility continues to improve during the balance training.

“…For American individuals over 65 years of age, falls are the leading cause of injury-related death [1][2][3][4]. Critical to reducing fall-risk in the mature, aging population are user-friendly,low-impact training methodologies for balance maintenance, improvement, and confidence (e.g., [5][6][7][8][9]).…”

“…Further, there is general agreement that decreased postural ability in mature & elderly individuals is linked to/could reflect pathologies associated with one or more of these sensory system components, as well as age-related changes and deterioration of motor and higher-level adaptive mechanisms [5,[11][12][13][14]. The improvement of elderly individual's balance via training is of relevant societal importance (e.g., [5][6][7][8][9]). However, how elderly individual's sensorimotor integration (to impact one's balance) is affected due to readily-accessible balance training methodologies, namely sensory-type training, requires more rigorous study.…”

Background: With increases in average life expectancy (i.e., 43 million Americans over 65 years old in 2012 and 72 million projected in 2030), the importance of investigating and establishing accessible training methodologies towards good balance and preventing falls has significant societal relevance. It is well known that information from somatosensory, visual and vestibular systems integrate to yield a postural response and that these systems may degrade with age. It was hypothesized that modest and accessible training exercises targeting sensory inputs and base-of-support (BOS) improves balance and balance confidence in mature participants (60-80 years old). Methods: Sixteen participants were assessed pre/post 6 weeks of training, 2 sessions/week involving moderate (meaning low-intensity) walking (wide and tandem) and standing (single-leg, tandem and double-leg) while we varied visual and somatosensory inputs (i.e., eyes-open/closed and hard surface & stiff/compliant foam surfaces). Baseline and final assessments included standard measures (Balance Error Scoring System (BESS) and Activities-specific Balance Confidence (ABC)), as well as forceplate-derived center-of-pressure (COP) displacement and velocity parameters. Results: From relatively simple, targeted exercises, we observed that BESS scores improved from broadly normal/poor (baseline) to superior (final) performance and improvements (decreases) in both COP parameters. Conclusions: The results of the training were significant in that by doing sensory/BOS exercises, the participants were able to improve postural control and balance; this implies decreased risk of losing stability and falls. Further, these exercises are accessible and simple enough to be translated to one's home.
