“…29 Furthermore, relatively few studies have been designed to examine the use of biofeedback in orthopaedic patients. 1,4,5,[7][8][9][15][16][17]19,25,27,28,37,38 The findings here suggest biofeedback may be an effective tool with orthopaedic patients. With additional research biofeedback devices may very well become a part of the mainstay of clinical practice in orthopaedic partial weightbearing patients.…”

Introduction: Physiotherapists use different methods such as tactile feedback, scales and biofeedback to teach patients applying the partial weight bearing instructions. Biofeedback systems are more effective and objective method than usage of conventional bathroom scales in training patients to comply with weight-bearing limitations. Aim: The current review will focus on the availability and clinical use of biofeedback in-shoe device in patients with prescribed PWB. Methods: A literature search was performed using the following keywords: partial weight bearing, biofeedback in-shoe device and surgery. Five databases were searched appropriate for screening (PubMed, PEDro, Google Scholar, Clinicaltrials.gov and ScienceDirect). Results: Filtration strategy was used in a literature search. 15 sources were selected for final analysis. Qualitative analytical approach was used in data processing. Conclusion: Biofeedback systems have been more effective than conventional bathroom scales in training patients to comply with weight-bearing limitations. With additional randomised controlled trials, biofeedback devices may very well become a part of the mainstay of clinical practice in orthopaedic partial weight-bearing patients.

“…The live-feedback system for PWB consists of the multimodal, mobile gait analysis system eSHOE, which was developed by the Central European Institute of Technology (CEIT RALTEC, Schwechat) in collaboration with the University of Applied Sciences Technikum Wien [11,[21][22][23] and an Android-application [39,40]. The eSHOE system are orthopaedic insoles with diferent sensor embedded, capable of measuring pressure under four specifc areas under the foot, 3D-acceleration as well as 3D angular velocity, available in sizes EUR36-EUR44.…”

Due to the demographic change, the need of rehabilitation is rising. Home-based rehabilitation can lower the fnancial burden, support reintegration into daily (work-)life and increase motivation as well as compliance of patients. Several device-supported approaches for rehabilitation were investigated in the research project REHABitation. An insole-based live-feedback system to support patients performing partial weight bearing was developed and tested in a clinical pilot study. Rehabilitative games using commercial gaming control systems like the Microsoft Kinect and the Nintendo Wii Balance Board were developed for range-of-motion and balance training, respectively. For these serious games, usability was tested with the System Usability Scale questionnaire. The comparability of range-of-motion measurements of shoulder movements conducted with inertial measurement units and an optical motion capture system was elaborated. Results fo the clinical study suggest that the patients' compliance with partial weight bearing load restriction was improved with the use of the live-feedback system developed. The use of Wii and Kinect solutions is possible and helps to increase compliance of patients due to high system usability scale scores and positive feedback. The use of intertial measurement units for the detection of motion and its characteristics is highly depending on the used type of system and the intended time span of use.

“…Several techniques have been employed in the pursuit of this goal, verbal instructions and the use of bathroom scales being the most common. Most of these methods have been shown to have poor outcomes in regards to the ability of the patient to reproduce the weightbearing protocol (Bril et al 2016). Hence, the device that is able to quantitatively assess the weight-bearing throughout the recovery process is an effective and functional substitute to techniques that are rather based on abstract explanations.…”

Partial Weight-Bearing (PWB) regime is a part of a recreation process for patients with lower limb fractures/strains/sprains. In order to avoid a frequent foot overloading and achieve better patient compliance with requirement of PWB, the application of Weight-Bearing Monitoring System (WBMS) is highly attractive. However, it is challenging to find an affordable material for protective insole cover that is also a good shock-absorber. In this regard, a new formulation for protective covering material that preserves and isolates the sensors of WBMS device is suggested in this thesis. Twenty one samples of renewably sourced Polyurethane Foam (PUF) composed of poly (trimethylene ether) glycol (PO3G) and unmodified castor oil (CO) were synthesized and evaluated according to predetermined criteria. Response surface methodology of Box – Behnken design was applied to study the effect of the following parameters (polyols ratio, isocyanate index (II), and blowing agent ratio) on the properties (hardness, density) of PUFs. Results showed that CO/PO3G/TDI PUFs with hardness Shore A 17-22 and density of 0.19-0.25 g/cm3 demonstrate the required characteristics and can potentially be used as a durable and functional insole material. Phase separation studies have found the presence of well-segregated structure in PUFs having polyols ratio CO:PO3G 1:3 and low II, which further explains their extraordinary elastic properties (400% elongation). Analysis of cushioning performance of PUF signified that 5 samples have Cushioning Energy (CE) higher than 70 N·mm and Cushioning Factor (CF) in the range of 4-8, hence are recommended for application in WBMS due to superior weight-bearing and pressure-distributing properties. Moreover, the developed formulation undergoes anaerobic soil bacterial degradation and can be categorized as “green” bio-based material.
