  • EFFECTS of ISOMETRIC HOLD EXERCISE with PASSIVE TERMINAL KNEE EXTENSION in RESTORING QUADRICEPS FUNCTION after ACL RECONSTRUCTION - RESEARCH DESIGN and METHODS
    Vijay Samuel Raj, Mruthyunjaya, Vijay Chandru
    Journal of Musculoskeletal Research, 2024
    Background: Inhibition of the quadriceps muscle activity and reduced knee extension strength in terminal extension is observed in most cases following anterior cruciate ligament (ACL) injuries and reconstruction. Quadriceps lag (QL), if it persists, can lead to limitation of functional and performance skills. The loss of quadriceps power may be due to reduced voluntary activation of the quadriceps muscle due to arthrogenic muscle inhibition (AMI). The possibility of physiotherapeutic intervention to reduce the AMI must be considered to decrease the QL, and improve muscle strength and functional recovery. There is a need to develop a specific exercise addressing arthrogenic muscle inhibition (AMI), to achieve complete knee extension at the early phase of rehabilitation. The trial is aimed to evaluate the effect of IEPTE in patients with quadriceps lag following anterior cruciate ligament reconstruction (ACLR). Methods: Randomized, Parallel Group Trial, including 36 patients ([Formula: see text] = 36) aged 18–50 years with ACLR, will be randomly allocated to isometric hold exercise with passive terminal knee extension (IEPTE) and ACL conventional exercise group (CG). The primary outcome for quadriceps lag and the secondary outcome of motor unit action potential (MUAP), pain and knee function will be evaluated. The IEPTE technique is developed by the author, who combined passive terminal knee extension with the isometric hold exercise to knee extensors. The effects of the exercise protocol will be evaluated using outcome measures at 0 (baseline), 2nd, 4th, 8th, 24th weeks. General linear mixed model for repeated measures with effect size tested using Cohen’s d will be used to analyze primary and secondary outcomes to investigate confounding interaction between groups and time. A statistically significant was set to [Formula: see text] < 0.05 (95% CI). The study results are expected to be completed by December 2023 and the results by 2024. Discussion: The exercise developed addresses the AMI and achieves knee extension at the early phase of rehabilitation. If proven to be effective, the early activation of the quadriceps may improve the knee function. This developed exercise (IEPTE) thus can be used in the ACL rehabilitation program and results will help to explore further to frame new guidelines and protocol.
  • Measuring transversus abdominis activity using pressure biofeedback unit—A technical report
    Vijay Samuel Raj, Mincy Thomas
    Physiotherapy Research International, 2023
    Background and PurposePressure biofeedback is a tool that can detect the movement of a structure and may be used as an indicator of muscle function. It's widely used to measure the transversus abdominis (TrA) muscle activity. Pressure biofeedback (PBU) monitors the abdominal wall movement by measuring the pressure change during abdominal hollowing and can indirectly evaluate the TrA muscle function, which is considered as a valuable tool. The evaluation of the training of core muscles, including the transversus abdominis, requires a reliable outcome. Various methods using different positions are used to evaluate the transversus abdominis muscle function. However, it is noted that a standard way of evaluation and training still needs to be improved in research and clinical practice. This technical report discusses the optimal position and technique to measure the TrA muscle activity using PBU, with discussions on the merits and demerits of the body positions.MethodsThe technical report is presented with a literature review of the PBU measurement of TrA and through observation in the clinical practice. The evaluation methods of TrA, including the position to activate and isolate, are discussed in detail.ResultsTraining core muscles does not imply TrA activation, and evaluating isolated TrA and multifidus is essential before intervention. The abdominal drawing‐in maneuver effectively activates TrA in various evaluation positions of the body, but when using PBUs, it would be valid in a prone position.DiscussionDifferent body positions are practiced to train TrA and core muscles using PBU, commonly adopted by practice are in supine. It's noted that most of the studies lack in establishing the effectiveness of the position in evaluating the TrA muscle activity using PBU. The need for insight into an appropriate technique for evaluating TrA activity is addressed in this technical report. This report presents key points on the complete technique and concludes that the prone position is superior to other positions and recommended for measuring and recording the TrA activity using a PBU.

  • Optimization of backpack loads using gait parameters in school boys
    Muhammed Rashid, Jerin Mathew, Vijay Samuel Raj V, Kavitha Raja
    Journal of Bodywork and Movement Therapies, 2021
    Background Backpacks are an efficient way of manual carriage used by people of all ages, and is commonly used by schoolchildren. Carrying heavy backpacks may result in cumulative trauma later in life due to biomechanical adaptations during gait. Gait parameters are known to be sensitive to force vectors, which can be altered by load carrying. This study attempts to find the most favorable backpack weight using gait changes as an indicator. Methods This was an observational study conducted on twenty typically developing boys aged between 09 to 14 years. Gait analysis was done using standard recommendations, with increasing backpack loads with respect to their body weights. Gait cycles were captured using video cameras and analyzed using Kinovea0.8.25 motion analyzing software. Results As the backpack load increased, significant kinematic changes were noted in the child's ankle, knee, and hip joints. These changes were evident when the backpack load increased beyond 15% of their body weight. Conclusions This study concludes that the optimum weight that can be carried without having an impact on dynamic posture will be less than 15% of the body weight.
