“…Normal range of plantar flexion is 0° to 50° from anatomical position. [28][29][30] However, plantar flexion range may be considerably increased in ballet dancers (average 113°). 31 Constraints on excessive movements at the ankle joint involve both static and dynamic joint components.…”

“…Thus, the ankle is "unlocked" (more talar tilt is allowed) and loses some of its bony stability when plantar flexed. 28 The ankle must then rely on ligamentous and musculotendinous support. As plantar flexion increases and bony stability decreases these soft tissues have higher demands placed on them and are more susceptible to injury.…”

“…No muscles attach to the talus; instead, they cross the ankle (both the talo-crural and sub-talar joints) to insert more distally on the foot. 28 The most important muscles that prevent inversion ankle sprains are the two muscles located on the lateral side of the lower leg: the peroneus longus and peroneus brevis. Their tendons pass along the lateral ankle (Fig.…”

The Relationship between Lateral Ankle Sprain and Ankle Tendinitis in Ballet Dancers

The lateral ligament complex of the ankle is the most frequently injured structure in the body. Although most simple ankle sprains do not result in long-term disability, a significant number do not completely resolve, leading to residual symptoms that may persist for years. The most commonly reported symptoms, particularly among athletes, include instability, re-injury and tendinitis. Ballet dancers are a combination of artist and high-performance athlete; consequently, they are subjected to the same types of injuries as other athletes, including lateral ankle sprains and their sequelae. Furthermore, ballet dancers perform in unusual positions such as en pointe, which places the ankle in extreme plantar flexion, requiring stabilization by surrounding muscles. Dancers’ extraordinary performance demands place them at risk for other ankle injuries as well, including inflammation of several tendons, especially the peroneals. This report reviews the relevant literature to characterize the scope of lateral ankle sprains and sequelae, discuss the importance of the peroneal muscles in ankle stability, and explore a relationship between lateral ankle sprain and ankle tendinitis in ballet dancers. Informal interviews were conducted with physical therapists who specialize in treating ballet dancers, providing a clinical context for this report. An extensive review of the literature was conducted, including electronic databases, reference lists from papers, and relevant reference texts. Numerous studies have investigated ankle sprains and residual complaints; nearly all report that lateral ankle sprains commonly lead to chronic ankle instability. Studies exploring ankle stability have demonstrated that the peroneal muscles play a crucial role in ankle stabilization; EMC studies confirm they are the first to contract during ankle inversion stress. The dancers need for exceptional ankle stabilization may lead to peroneal overuse and tendinitis. Studies have linked peroneal pathology to a history of ankle sprain, but there is no dance medicine literature linking peroneal tendinitis to prior ankle sprains. A growing body of literature confirms myriad connections between lateral ankle sprains, residual instability, peroneal muscle increased activity, and tendinitis. It is our belief that ankle sprains lead to instability, particular en pointe, for which the peroneal muscles attempt to compensate. Their overuse for this static stabilizing function, as well as for dynamic dance movements, then leads to tendonitis. This knowledge may heighten awareness of the potential for developing tendonitis following ankle sprains, and lead to better rehabilitation of the injured ballet dancer.

“…One of them is a survey conducted by the National Health and Nutrition Examination Survey, showing that the risk of knee osteoarthritis increases almost four times in women with obesity, and 4.8 times in men who are obese (Ho-Pham, Lai, Mai, Doan, & Nguyen, 2016). During the single-leg stance phase, the knee will take 3-6 times body weight (Melchiorre, 1996). Each weight gain will be multiplied by this number, illustrating how much weight passes through the knee on someone who has more weight when walking.…”

“…Each weight gain will be multiplied by this number, illustrating how much weight passes through the knee on someone who has more weight when walking. The increase in axial load will cause a resultant shift in the force acting on the knee joint towards the medial and an increase in knee adduction movement on the knee thereby increasing the load that passes through the medial compartment of the knee, which can trigger knee osteoarthritis, especially in the medial compartment of the knee (Melchiorre, 1996). Among obese people who also experience knee osteoarthritis, there is an increase in knee pain that causes limited activity, as well as the risk of needing a knee joint replacement (Ho-Pham et al, 2016).…”

The Comparison of Analogue Pain Scale, Quadriceps Muscle, and Knee Joint among Obese Women with Knee Osteoarthritis

Introduction: Patients with knee osteoarthritis were reported to have quadriceps weakness and impaired knee function, related to pain. It is unclear whether body composition is a causal factor to the above findings. Aim: The purpose of this study was to investigate differences in pain, quadricep strength, and knee function among obese women and women of normal weight with knee osteoarthritis. Methods: Fifty women with a mean age of 55 years were involved in this study. The inclusion criteria were bilateral knee of knee osteoarthritis with a visual analogue pain scale difference (>1) between each knee. Patients all underwent assessment of the pain intensity, isokinetic strength of knee muscles, and knee function. Results: The analysis showed that there were significant differences between groups in pain intensity (p=0.004) and quadriceps strength (p=0.003) but were not significant on the Lequesne index score (p=0.05). Significant differences in the intensity of knee pain and quadriceps strength occurred between the obesity II group with the normal weight group (p=0.004), overweight (p=0.017) and with obesity I (p=0.017) suffering from knee osteoarthritis. Conclusion: Normal weight people with knee osteoarthritis are at risk of suffering knee pain that causes reduced physical activity. This inactive condition will also result in a decrease in quadriceps muscle strength, which can increase the risk of knee deformity. Therefore, proper education and training programmes are required to anticipate this, so as to prevent the progression of knee osteoarthritis.

This paper presents the development of an upper limb end-effector based rehabilitation device for stroke patients, offering assistance or resistance along any 2-dimensional trajectory during physical therapy. It employs a non-backdrivable ball-screw-driven mechanism for enhanced control accuracy. The control system features three novel algorithms: First, the Implicit Euler velocity control algorithm (IEVC) highlighted for its stateof-the-art accuracy, stability, efficiency and generalizability in motion restriction control. Second, an Admittance Virtual Dynamics simulation algorithm that achieves a smooth and natural human interaction with the non-backdrivable end-effector. Third, a generalized impedance force calculation algorithm allowing efficient impedance control on any trajectory or area boundary. Experimental validation demonstrated the system's effectiveness in accurate end-effector position control across various trajectories and configurations. The proposed upper limb endeffector-based rehabilitation device, with its high performance and adaptability, holds significant promise for extensive clinical application, potentially improving rehabilitation outcomes for stroke patients.
