AbstractPurpose : Limb amputation is followed by an important rehabilitation process, especially when a prosthesis involved. The objective of this study to assess the nature factors related health quality life (HRQL) persons with limb amputation. Method Nottingham Health Profile (NHP) treated 1011 subjects major one or several limbs. Correlations were sought in multivariate regression model analyses between six categories distress explored NHP and age, sex, cause level programme. Results...

Several postoperative complications associated with pain may develop in the stump of an amputated lower limb. Clinical findings are often nonspecific; however, radiologic evaluation, especially magnetic resonance (MR) imaging, is useful early diagnosis these complications, thereby helping minimize physical disability its psychologic and socioeconomic implications. Conventional radiography can demonstrate evidence osseous origins (eg, aggressive bone edge, heterotopic ossification,...

Decoding finger and hand movements from sEMG electrodes placed on the forearm of transradial amputees has been commonly studied by many research groups. A few recent studies have shown an interesting phenomenon: simple correlations between distal phantom finger, wrist voluntary muscle activity in residual upper arm transhumeral amputees, i.e., groups that, prior to amputation, had no physical effect concerned joints. In this study, we are going further into exploration phenomenon setting up...

Most transhumeral amputated individuals deplore the lack of functionality their prosthesis due to control-related limitations. Commercialized prosthetic elbows are controlled via myoelectric signals, yielding complex control schemes when users have an entire limb. Limited causes development compensatory strategies. An alternative strategy associates residual limb motions automatize elbow motion using a model physiological shoulder/elbow synergies. Preliminary studies shown that could be...

Controlling several joints simultaneously is a common feature of natural arm movements. Robotic prostheses shall offer this possibility to their wearer. Yet, existing approaches control robotic upper-limb prosthesis from myoelectric interfaces do not satisfactorily respond need: standard methods provide sequential joint-by-joint motion only; advanced pattern recognition-based allow the limited subset synchronized multi-joint movements and remain complex set up. In paper, we exploit method an...

Transhumeral amputees face substantial difficulties in efficiently controlling their prosthetic limb, leading to a high rate of rejection these devices. Actual myoelectric control approaches make use slow, sequential and unnatural, especially for patients with level amputation who need prosthesis numerous active degrees freedom (powered elbow, wrist, hand). While surgical muscle-reinnervation is becoming generic solution increase capabilities over prosthesis, research still being conducted...

Next generation prosthetics will rely massively on myoelectric "Pattern Recognition" (PR) based control approaches, to improve their users' dexterity. One major identified factor of successful functioning these approaches lies in the training amputees and understanding how those works. We thus propose here an intuitive pattern similarity biofeedback which can be easily used train allow them optimize muscular contractions performance. Experiments were conducted twenty able-bodied participants...

The aim of this study was to analyze the displacements center pressure (COP) using an in-shoe recording system (F-Scan) before and after motor nerve block neurotomy tibial in spastic equinovarus foot. Thirty-nine patients (age 45 ± 15 yr) underwent a block; 16 38 15.2 had neurotomy, combined with tendinous surgery (n = 9). displacement COP (anteroposterior [AP], lateral deviation [LD], posterior margin [PM]) compared between paretic nonparetic limbs surgery. At baseline, limb higher AP (17.3...

Abstract The objective of the study was to demonstrate non-inferiority low-frequency spa therapy combined with rehabilitation (Spa-rehab) versus standard at 6 months for symptomatic knee osteoarthritis (KOA). A prospective, randomized, monocenter, trial recruitment community-based KOA patients performed. Standard comprised standardized treatment, days a week 3 weeks, and Spa-rehab sessions, followed by dedicated program, weeks. primary endpoint achieving minimal clinically important...

Abstract There is an increasing need to extend the control possibilities of upper limb amputees over their prosthetics, especially given development devices with numerous active joints. One way feeding pattern recognition myoelectric rely on activities residual associated phantom movements (PLM). This study aimed describe types, characteristics, potential influencing factors and trainability PLM. Seventy-six below- above-elbow major amputation underwent a semi-directed interview about limb....

Voluntary phantom movements are systematically associated with muscle contractions in the residual limb. These latter specific to type of movement and can be classified by pattern recognition algorithms. However, mobility generates fatigue that could impact classification metrics. This study explored whether daily training at home no other feedback than inherent somatosensory information success rate. Kinematics activity were compared between before after a two-month six major upper limb...

An arm amputation is extremely invalidating since many of our daily tasks require bi-manual and precise control hand movements. Perfect prostheses should therefore offer a natural, intuitive cognitively simple over their numerous biomimetic active degrees freedom. While efficient polydigital are commercially available, remains complex to master offers limited possibilities, especially for high levels. In this pilot study, we demonstrate the possibility upper-arm amputees intuitively...

Return to work (RTW) after surgery for a work-related rotator cuff disorder (WRRCD) is often difficult. The study's purpose was identify preoperative factors predicting RTW.Ninety-two workers with WRRCD were identified by four surgeons. Before surgery, the completed series of standardized questionnaires related working conditions, health, and health beliefs. They followed up prospectively 20 months. Statistical analysis based on single multiple-factor Cox models duration absence from time...

The functionalities of myoelectric hooks, such as whether they allow wrist movements, well the volume and design devices, may impact how fitted transradial amputees use their upper limbs. aim current study was to compare two prosthetic hooks in terms compensatory shoulder functionality user satisfaction. This monocentric, randomized, controlled, cross-over trial evaluated eight with Greifer Axon-Hook, during consecutive periods. At end each period, abduction (mean percentage time > 60°)...
