“…Turning to look behind requires weight shifting onto each leg and transverse plane rotation not typically provided in prosthetic components. Including visual and vestibular confounding in a multisystem approach to improve balance [35] is recommended to encourage development of the proprioceptive system contribution to balance [36], particularly in the rehabilitation of people with lower-limb loss who adaptively place more weight bearing on one leg [37]. Notably, BBS 14 (standing on one leg) was not an independent variable for prosthetic success in this study.…”

Abstract-For people with lower-limb loss, impaired balance is common and limits prosthetic function within the community. This cross-sectional study (1) analyzed relationships among prosthetic use for mobility, balance ability and confidence, and amputation-related variables and (2) determined multivariate models to identify level of prosthetic use. Subjects included 46 community-dwelling adults (mean age 56.2 yr) with limb loss (91.3% unilateral) of varied levels (52.2% transtibial) and etiologies (69.6% vascular). A three-variable linear regression model including balance ability, balance confidence, and years since amputation explained 63.7% of variance in the Houghton scale of prosthetic use score. A logistic regression model including the 14-task Berg Balance Scale, balance confidence, years since amputation, age, and number of comorbidities correctly differentiated between people who had reached a satisfactory level of prosthetic use or not 89.1% of the time. The first three variables demonstrated moderate accuracy with positive likelihood ratios from 2.34 to 4.35. The regression model was further reduced to correctly classify 87.0% of cases with three balance ability tasks (retrieving objects from floor, turning to look behind, and placing alternate foot on stool), balance confidence, and numbers of comorbidities. Logistic models that include balance ability, balance confidence, and numbers of comorbidities can identify level of prosthetic use in people with lower-limb loss. Increased balance confidence and ability when retrieving objects from floor, turning to look behind, and placing alternate foot on stool were most indicative of successful prosthetic use for mobility.

“…This finding has been corroborated by previous studies in healthy individuals (3,4,14,15,24). Other studies have demonstrated that standing on a single limb is more difficult without vision, indicating that the more challenging the task, the more the balance control mechanisms rely on vision (25). …”

“…Very few studies have examined the postural control of low-vision subjects in a single-leg stance under different eye conditions. The proprioception inputs could be overloading the left leg, as previous studies have suggested that unilateral stance tasks might depend on some neuromuscular requirement (25) and muscular strength (3,12,13). The ability of the postural control system to select a higher joint configuration variance (2,28) can contribute to the maintenance of postural stability by correcting lower extremity movements in individuals with vision impairments.…”

OBJECTIVE:This study aimed to evaluate the influence of reduced visual information on postural control by comparing low-vision and normal-vision adults in static and dynamic conditions.METHODS:Twenty-five low-vision subjects and twenty-five normal sighted adults were evaluated for static and dynamic balance using four protocols: 1) the Modified Clinical Test of Sensory Interaction on Balance on firm and foam surfaces with eyes opened and closed; 2) Unilateral Stance with eyes opened and closed; 3) Tandem Walk; and 4) Step Up/Over.RESULTS:The results showed that the low-vision group presented greater body sway compared with the normal vision during balance on a foam surface (p≤0.001), the Unilateral Stance test for both limbs (p≤0.001), and the Tandem Walk test. The low-vision group showed greater step width (p≤0.001) and slower gait speed (p≤0.004). In the Step Up/Over task, low-vision participants were more cautious in stepping up (right p≤0.005 and left p≤0.009) and in executing the movement (p≤0.001).CONCLUSION:These findings suggest that visual feedback is crucial for determining balance, especially for dynamic tasks and on foam surfaces. Low-vision individuals had worse postural stability than normal-vision adults in terms of dynamic tests and balance on foam surfaces.

“…However, using the non-injured leg as a reference level is not recommended due to changes in this side as well; therefore, comparisons with healthy age-matched persons might reveal even larger differences [10]. In addition, more challenging tasks, like single-leg balancing on an unstable surface, resulted in larger and faster COP excursions because all sensory sensors and sensory integration are stimulated [22]. Our data showed a larger COP range only in AP direction for the unstable surface, and an increased COP speed in AP direction for the stable surface was found.…”

Aim: To compare single-leg balance performance between subacute ankle sprain patients receiving no exercise therapy and healthy persons.Methods: Forty-eight subacute ankle sprain patients (age = 34.3 ±9.7 years) and 10 healthy persons (age = 30.1 ±4.7 years) participated in the study. Participants underwent an assessment of body functions and a 30-second single-leg balance test on a force plate under stable and unstable conditions. Center of pressure (COP) range, length and speed in mediolateral (ML) and anteroposterior (AP) directions were calculated.Results: All healthy persons finished the 30-second balance test under both conditions. Forty-three patients (90%; P=.374) were able to complete the test on the stable surface and 38 patients (79%; P=.125) on the unstable surface. Ankle sprain patients showed increased COP AP speed compared to healthy persons for stable conditions (P=.009) and a larger COP AP range for unstable conditions (P=.001). Furthermore, muscle strength in inversion and eversion were correlated to COP performance (P<.050). Conclusion:Specific ankle strength exercises, including muscle strength exercises in the frontal plane, might improve balance performance in ankle sprain patients.
