“…Although our sample of 21 participants is comparable to other studies investigating gait and foot pressures, more fulsome samples are required to have sufficiently powered studies for investigating potential gender effects in walking aid use. 12 Standardization of the walking path surface to a smooth indoor surface limits the application of our findings to other conditions such as carpet or outdoor environments as encountered in activities of daily living. Specifically, we did not assess the added difficultly walking aid selection could have on stair use.…”

Background: Young adults often tolerate the increased energy expenditure, coordination, and stance limb discomfort associated with walking aids for nonweightbearing ambulation. Adults aged ≥50 years may not have the same tolerance. Therefore, the objective of this study was to determine how walking aid selection affects stance limb plantar force, walking speed, perceived exertion, and device preference in adults aged ≥50 years. Methods: A prospective randomized crossover study was performed using healthy adults, aged ≥50 years, with no use of walking aids within 5 years. Participants walked 200 m in 4 randomized conditions: single nonweightbearing ambulation using crutches, a walker, a wheeled knee walker, and unaided walking. An in-shoe sensor measured stance limb plantar force, a stopwatch timed each walk, perceived exertion was reported using the BORG CR-10 scale, and device preference was identified. Results: Twenty-one participants (7 male; age: 56 ± 5 years; BMI: 26.6 ±1.9) showed stance limb plantar force was lowest when using a wheeled knee walker ( P < .001). Walking speed was similar in unaided and wheeled knee walker conditions (1.41 and 1.31 m/s), but slower with crutches or a walker (42%-68%, P < .001). Perceived exertion was similar in unaided and wheeled knee walker conditions (1.6 and 2.8), but higher with crutches or a walker (5.7 and 6.1, P < .001). Most (20/21) participants preferred the wheeled knee walker. Conclusions: Using a wheeled knee walker for nonweightbearing ambulation reduced stance limb plantar force, maintained unaided walking speed and perceived exertion, and was preferred to crutches or a walker. Level of Evidence: Level II, comparative study.

“…A validation set of 10 studies was created, 12,37,[46][47][48][49][50][51][52][53] that included key offloading studies published since our previous search (13 August 2018). 33 Using this set, the search strings were validated by ensuring each study in the set was identified, before the search strings were finalised and used in this review.…”

BackgroundOffloading treatment is crucial to heal diabetes‐related foot ulcers (DFU). This systematic review aimed to assess the effectiveness of offloading interventions for people with DFU.MethodsWe searched PubMed, EMBASE, Cochrane databases, and trials registries for all studies relating to offloading interventions in people with DFU to address 14 clinical question comparisons. Outcomes included ulcers healed, plantar pressure, weight‐bearing activity, adherence, new lesions, falls, infections, amputations, quality of life, costs, cost‐effectiveness, balance, and sustained healing. Included controlled studies were independently assessed for risk of bias and had key data extracted. Meta‐analyses were performed when outcome data from studies could be pooled. Evidence statements were developed using the GRADE approach when outcome data existed.ResultsFrom 19,923 studies screened, 194 eligible studies were identified (47 controlled, 147 non‐controlled), 35 meta‐analyses performed, and 128 evidence statements developed. We found non‐removable offloading devices likely increase ulcers healed compared to removable offloading devices (risk ratio [RR] 1.24, 95% CI 1.09–1.41; N = 14, n = 1083), and may increase adherence, cost‐effectiveness and decrease infections, but may increase new lesions. Removable knee‐high offloading devices may make little difference to ulcers healed compared to removable ankle‐high offloading devices (RR 1.00, 0.86–1.16; N = 6, n = 439), but may decrease plantar pressure and adherence. Any offloading device may increase ulcers healed (RR 1.39, 0.89–2.18; N = 5, n = 235) and cost‐effectiveness compared to therapeutic footwear and may decrease plantar pressure and infections. Digital flexor tenotomies with offloading devices likely increase ulcers healed (RR 2.43, 1.05–5.59; N = 1, n = 16) and sustained healing compared to devices alone, and may decrease plantar pressure and infections, but may increase new transfer lesions. Achilles tendon lengthening with offloading devices likely increase ulcers healed (RR 1.10, 0.97–1.27; N = 1, n = 64) and sustained healing compared to devices alone, but likely increase new heel ulcers.ConclusionsNon‐removable offloading devices are likely superior to all other offloading interventions to heal most plantar DFU. Digital flexor tenotomies and Achilles tendon lengthening in combination with offloading devices are likely superior for some specific plantar DFU locations. Otherwise, any offloading device is probably superior to therapeutic footwear and other non‐surgical offloading interventions to heal most plantar DFU. However, all these interventions have low‐to‐moderate certainty of evidence supporting their outcomes and more high‐quality trials are needed to improve our certainty for the effectiveness of most offloading interventions.

“…2 Further, in patients treated with removable casts and walkers, the contralateral side is subject to high-pressure loads beneath the forefoot, including the hallux, first, second, third, and fifth metatarsal heads. 14 The clinical consequences of this pressure elevation on the contralateral foot are unclear. Whether patients and surgeons should expect an increase on contralateral ulcers and amputations has yet to be reported.…”

Background: The contralateral foot in Charcot arthropathy or neuroarthropathy (CN) is subject to increased plantar pressure. To date, the clinical consequences of this pressure elevation are yet to be determined. The aim of this study was to evaluate ulcer and amputation rates of the contralateral foot in CN. Methods: We abstracted the medical records of 130 consecutive subjects with unilateral CN. Rates of contralateral CN development and recurrence, contralateral ulcer development, and contralateral amputations were recorded. Statistical analysis was performed to identify possible risk factors for contralateral CN and ulcer development, and contralateral amputation. Mean follow-up was 6.2 (SD 4) years. Results: After a mean of 2.5 years, 19.2% patients developed contralateral CN. Female gender was associated with contralateral CN development (odds ratio 3.13, 95% confidence interval 1.27, 7.7). Overall, 46.2% patients developed a contralateral ulcer. Among the patients who developed contralateral CN, 60% developed an ulcer. Sanders type 2 at the index foot (midfoot CN) was significantly associated with contralateral ulcer development. Ulcer-free survival (UFS) differed significantly between patients with diabetes type 1 (median UFS 5131 days) and patients with diabetes type 2 (median UFS 2158 days). A total of 25 amputations had to be performed in 22 (16.9%) patients. Three of those 22 patients (2.3%) needed major amputation. Conclusion: Almost 20% of patients developed contralateral CN. Nearly half of people with CN developed a contralateral foot ulceration. Patients with type 2 diabetes had significantly shorter UFS than patients with diabetes type 1. Every sixth patient needed an amputation, with the majority being minor amputations. The contralateral foot should be monitored closely and included in the treatment in patients with CN. Level of Evidence: Level IV, retrospective study.
