“…Higher mean self-selected speeds among participants in our study may be attributed to participants being established prosthesis users, rather than new prosthesis users (i.e. gait speed was assessed at rehabilitation discharge in Batten et al's 35 work). In our study, significant between-K-level differences in self-selected walking speed, as well as novel findings regarding the use of self-selected walking speed to determine cadence variability potential, highlight the usefulness of self-selected gait speed assessment when classifying functional mobility level among adults with LLL.…”

“…Furthermore, self-selected gait speed is predictive of prosthesis nonuse postamputation, with speeds ⩽ 0.44 m/s indicating greater risk for nonuse. 34 Recently, Batten et al 35 reported significant differences in self-selected walking speeds between individuals with LLL based on K-level classification, with median gait speeds of 0.38 m/s, 0.63 m/s, and 1.06 m/s for individuals classified as K2-, K3-, and K4, respectively. In our study, post hoc analyses support Batton et al's findings with significance between K-level differences for mean selfselected gait speeds after controlling for covariates (i.e.…”

Background: In the United States, Medicare Functional Classification Level (K-level) guidelines require demonstration of cadence variability to justify higher-level prosthetic componentry prescription; however, clinical assessment of cadence variability is subjective. Currently, no clinical outcome measures are associated with cadence variability during community ambulation. Objectives: Evaluate whether physical performance, i.e. 10-meter Walk Test (10mWT)-based walking speeds, L-Test, and Figure-of-8 Walk Test scores, is associated with community-based cadence variability among individuals with a transtibial amputation. Study design: Cross-sectional. Methods: Forty-nine participants, aged 18–85 years, with a unilateral transtibial amputation were included. Linear regression models were conducted to determine whether physical performance was associated with cadence variability (a unitless calculation from FitBit® OneTM minute-by-minute step counts), while controlling for sex, age, and time since amputation ( p ⩽ .013). Results: Beyond covariates, self-selected gait speed explained the greatest amount of variance in cadence variability (19.2%, p < .001). Other outcome measures explained smaller, but significant, amounts of the variance (11.1–17.1%, p = .001–.008). For each 0.1 m/s-increase in self-selected and fast gait speeds, or each 1-s decrease in L-Test and F8WT time, community-based cadence variability increased by 1.76, 1.07, 0.39, and 0.79, respectively ( p < .013). Conclusions: In clinical settings, faster self-selected gait speed best predicted increased cadence variability during community ambulation. Clinical relevance The 10-meter Walk Test may be prioritized during prosthetic evaluations to provide objective self-selected walking speed data, which informs the assessment of cadence variability potential outside of clinical settings.

“…The literature has shown that increased gait skill is linked to an improvement in mobility. 20 However, rarely is mobility seen as a skill that can be taught; instead, it is viewed as an outcome measure that is influenced by gait ability. 18,20 The clinic appears to meet a key aspect of rehabilitation that is currently missing from the participants’ health experience which influences peoples’ ability to participate.…”

Background: Mobility clinics are designed to extend gait and mobility training beyond rehabilitation programmes. No research has been undertaken into participants’ experiences of attending these multidisciplinary, experience-based clinics. Research in this area is needed to ensure clinics meet intended goals, including understanding the motivation and experience of attendees. Insights may improve mobility clinics and inform strategies to encourage greater participation. Objectives: To explore the motivation of people with limb loss to attend a mobility clinic, the experience of participation and their perception of the clinic’s benefits. Study design: Qualitative methodology, naturalistic enquiry. Methods: Semi-structured interviews were conducted with nine clinic attendees during the clinic. Interviews were transcribed verbatim, data thematically analysed and emergent themes underwent member checking. Results: Three themes emerged from the data: facing the challenge captured how participants’ have adapted to amputation, valuing peers highlights the important role of peers in learning and support and improving mobility described the ongoing quest to improve mobility. Conclusion: The mobility clinic was attractive to those who liked challenges and was an invaluable source of learning for those wishing to improve their mobility. Future clinics should ensure that peer education is supported, and activities cater for a range of skills and fitness levels. Clinical relevance Findings of this study indicate that those who attended the mobility clinic liked to challenge themselves. Participation with peers was an important source of learning and support. Those participants who had previously attended a mobility clinic reported improvements in their overall daily function.

“…The test initiated when the evaluator said "go" and ended when the participant sat down with the back resting (Figure 2A). For 10MWT, participants were instructed to walk at a self-selected speed (comfortable) on a flat surface with 10 m ( Figure 3A) (Batten et al, 2019). Raw acceleration data from the IMU system were extracted using the G-sensor R software and exported in ASCII format.…”

Parkinson's disease (PD) is a neurodegenerative condition that is often associated with movement impairments, such as reduced balance and gait control. Virtual reality (VR) is a promising intervention for enhancing rehabilitation efficiency and may assist in overcoming functional limitations imposed by the disability. The objective of this study was to evaluate the feasibility, safety, and efficacy of a 5-weeks VR intervention in increasing mobility smoothness in participants with PD. Participants were assessed using functional mobility tasks-Timed Up and Go (TUG) and 10-m walking test (10MWT) and cognitive function tests. A total of 23 participants with a diagnosis of PD were randomly assigned to groups of VR or control interventions. In the VR group, for each session, participants received a VR-based balance training, i.e., tightrope simulator, for 20 min, preceded by 8 min of total body warm-up (total of 10 sessions over 5 weeks). Participants in the control group received 20 min of psychoeducation without a structured exercise program (twice a week). All screened participants engaged and completed a total of 10 VR-based intervention sessions. VR-based balance training caused no significant improvement in mobility smoothness for TUG or 10MWT (p > 0.05). Similarly, cognitive function was not affected by the VR intervention (p > 0.05). The outcomes of this study suggest that 10-20 min of VR-based intervention is a feasible and safe rehabilitation activity. However, it was insufficient to promote improvement in mobility smoothness and cognitive function in participants with PD. A combination of task-specific training in the virtual and physical environments in a more intensive approach is warranted for future study designs.
