Advantages of biomechanical analysis with Lynx

29 July, 2019

Biomechanics makes it possible to assess the state and evolution of a lesion or a musculoskeletal pathology, and to evaluate the efficiency of the treatment or rehabilitation therapy through dynamic tests. In order to carry out this study, a tool such as Lynx is essential, which allows to obtain objective and reliable data and make  optimal clinical decisions.

Biomechanical study in physical rehabilitation

“Biomechanics, through technological systems, collects data, analyses and studies the movement, balance, resistance and/or strength of tissues and muscles when walking, running or being in a certain position”.  This was explained by Mónica Macía, doctor at the mutual MAZ of Zaragoza, during the National Congress of the Spanish Society of Rehabilitation and Physical Medicine (SERMEF) recently held in Seville. She also indicated that biomechanical analysis allows us to objectify the evolution of difficult lesions such as cervical pain which, in many cases, are derived from traffic accidents and which represent an important expense in Rehabilitation.

The expert stressed that “rehabilitation doctors are very much used to  static tests that do not quite give all the necessary information”. Therefore, through biomechanics “we can see what limitation is occurring and assess when the patient should continue with treatment”. In addition to evaluating the efficacy of different treatments, a study of biomechanical parameters can be used to evaluate the proposed surgery or the indication of prostheses.

Motion analysis using inertial sensors

Juan Carlos Miangolarra, director of the Laboratory of Movement Analysis, Biomechanics, Ergonomics and Motor Control, said in an interview for  Infosalus that “biomechanics evaluates and detects functional changes. And, above all, changes that cannot be appreciated by the human eye”. At DyCare we believe that precision in motion capture and detection of motion limitations or compensations is only possible through the use of technology.

In order to provide professionals with reliable and objective data in the functional assessment of the patient, we have opted for an innovative solution: Lynx.  Silvia Raga, CEO of DyCare, says they launched the device because “very subjective methods were still used and there was a lack of objective and simple tools that could provide accurate data to see if the patient had really improved”.    

Lynx captures movements using two inertial sensors or four if a simultaneous biomechanical measurement of a healthy joint and a pathological joint is performed. Wearable sensors transmit every movement of the patient in real time and the software automatically quantifies all biomechanical parameters such as range of joint movement or speed.  “Through this motion analysis device, we want to give a tool to the professional that improves the diagnosis and treatment of the patient” explains Raga in Kapital Empresa.

Some physiotherapy clinics already work with Lynx on a daily basis, such as Punto Vital, a medical centre specialized in medical-legal assessment that uses DyCare’s solution to assess cervical-related musculoskeletal disorders and support expert reports. Likewise, centres dedicated to sports training and rehabilitation such as the Centre d’Alt Rendiment Esportiu de Sant Cugat (CAR), which uses Lynx inertial sensors in various studies on the monitoring of performance optimization exercises  and mobility exercises for the prevention and re-adaptation of injuries to sportsmen and women.
