Spatio-temporal parameters of human gait, currently measured using different methods, provide valuable information on health. Inertial Measurement Units (IMUs) are one such method of gait analysis, with smartphone IMUs serving as a good substitute for current gold-standard techniques. Here we investigate the concurrent validity of a smartphone placed in a front-facing pocket to perform gait analysis. Sixty community-dwelling healthy adults equipped with a smartphone and an application for gait analysis completed a 2-min walk on a marked path. Concurrent validity was assessed against an APDM mobility lab (APDM Inc.; Portland, OR, USA). Bland–Altman plots and intraclass correlation coefficients (agreement and consistency) for gait speed, cadence, and step length indicate good to excellent agreement (ICC2,1 > 0.8). For right leg stance and swing % of gait cycle and double support % of gait cycle, results were moderate (0.52 < ICC2,1 < 0.62). For left leg stance and swing % of gait cycle left results show poor agreement (ICC2,1 < 0.5). Consistency of results was good to excellent for all tested parameters (ICC3,1 > 0.8). Thus we have a valid and reliable instrument for measuring healthy adults’ spatio-temporal gait parameters in a controlled walking environment.

Acute lower limb ischemia (ALLI) is defined as a sudden decrease in lower limb arterial perfusion, which lasts less than 14 days and threatens a limb viability. This condition is one of the most common emergencies in vascular surgery, requiring immediate diagnosis and treatment, because untimely revascularization of lower limb leads to high amputation rate and mortality in postoperative period. Currently there exist many methods of lower limb revascularization, however, in fact, they all can be divided into two large groups: open, surgical, and endovascular treatment. The choice between them depends on many factors. Since introduction of Fogarty catheter, balloon thromboembolectomy became a «gold standard» in treatment for ALLI. Nevertheless, at the same time endovascular methods appeared, the first one being catheter-based thrombolysis (CBT). Since its appearance, CBT gradually improved with deeper understanding of indications for its use, improvement of the technique of intervention, appearance of different thrombolytic agents and instruments. Nowadays a number of international guidelines determine CBT as a first line treatment of most patients with ALLI. Endovascular thrombectomy techniques appeared in the 90s of XX century as an attempt tocombine advantages of open surgery (rapid and, in ideal conditions, complete restoration of limb perfusion) and of endovascular intervention (minimal invasiveness). They include manual aspiration, rheolytic (hydrodynamic), rotational, aspiration thrombectomy and pharmacomechanical thrombolysis. According to numerous studies, these techniques demonstrate quite impressive results and, probably, in the near future one of them can become a new «gold standard» in treatment for ALLI.

The Chapter will include a brief note on Amputation, Particularly Lower Limb Amputation (LLA), Levels and Causes of LLA. Importance of Prosthetics for LLA are explained in detail. The types of Prosthesis, Application (Donning & Doffing) of prosthesis are included in this chapter. Diagrammatic representation of the prosthesis are added too. Bio mechanical component is explained in detail within this chapter. The advantages and disadvantages of each and every Lower limb Prosthesis are clearly mentioned. Moreover, the Gait analysis & Training after the application of prosthesis are discussed. The reader will get a complete picture of Prosthetics for Lower limb Amputation by going through this chapter for lower limb prosthesis.

Background: Different types of ankle-foot orthoses are commonly used following lower limb surgery in children with bilateral spastic cerebral palsy. After three-dimensional gait analysis 1 year postoperatively, many children are recommended continued use of ankle-foot orthoses. Objectives: Our aims were to quantify the impact of ankle-foot orthoses on gait 1 year postoperatively and evaluate predictors for clinically important improvement. Study design: Prospective cohort study. Methods: A total of 34 ambulating children with bilateral cerebral palsy, with mean age 11 years (range 6–17), comprising 12 girls and 22 boys, were measured with three-dimensional gait analysis preoperatively (barefoot) and 1 year postoperatively (barefoot and with ankle-foot orthoses). Outcome was evaluated using gait profile score, key kinematic, kinetic and temporal–spatial variables in paired sample comparisons. Logistic regression was used to evaluate predictors for clinically important improvement with orthoses (⩾1.6° change in gait profile score). Results: Walking barefoot 1 year postoperatively, major improvements were seen in gait profile score and key variables. With ankle-foot orthoses, there were significantly improved step length and velocity, additional moderate reduction/improvement in gait profile score and knee moments and decreased stance ankle dorsiflexion compared to barefoot. Children using ground reaction ankle-foot orthoses ( n = 14) decreased stance knee flexion from 13.9° walking barefoot to 8.2° with orthoses. High gait profile score and more gait dysfunction preoperatively were significant predictors of clinically important improvement walking with orthoses. Conclusion: The results indicate improved gait function walking with ankle-foot orthoses versus barefoot 1 year after lower limb surgery. Stronger impact of ankle-foot orthoses was found in children with more pronounced gait dysfunction preoperatively. Clinical relevance The 1-year postoperative three-dimensional gait analysis is a useful method to assess treatment outcome after lower limb surgery in children with bilateral cerebral palsy and could also guide clinicians whether further treatment with ankle-foot orthoses is indicated, using clinically important differences as thresholds to evaluate their impact on gait.
