Introduction [0:15]
The lecture begins by introducing a scenario involving Naman, a long-distance runner experiencing knee stiffness and an old ankle injury. The presenter outlines the learning objectives, which include understanding the importance of joint mobility, identifying factors influencing it, exploring assessment methods, and discussing techniques to address joint mobility issues. The lecture aims to provide answers to queries related to differentiating mobility from flexibility and how to proceed with assessment and treatment.
Importance and Definition of Joint Mobility [1:33]
Joint mobility is defined as the active range of motion available at a joint, influenced by the joint capsule, surrounding muscles, and neuromuscular control. It is essential for maintaining functional performance, preventing injuries, and enhancing biomechanics, playing a vital role in rehabilitation and return-to-play protocols. Mobility is an active range of motion, while flexibility is a passive component dependent on connective tissue and muscle length, making flexibility a subset of mobility.
Factors Affecting Joint Mobility [2:35]
Both anatomical and physiological factors influence joint mobility, including joint shape and structure, capsule and ligament compliance, muscle bulk and tone, and neuromuscular activation and control. Pathological issues like inflammation, scar tissue, or adhesions can also impair joint mobility.
Assessment and Classification of Joint Mobility [3:09]
Joint mobility can be assessed clinically using joint-specific range of motion testing with tools like goniometers and inclinometers, as well as functional movement screens. Assessments can be active or passive, with comparisons between sides to identify symmetrical differences. Deficits can be classified based on soft tissue restriction, joint capsule tightness, motor control limitations, or pathological causes like pain and inflammation.
Goals of Mobility-Based Training [5:09]
Establishing clear goals is crucial for mobility-based training, including rehabilitation and performance goals. Immediate goals include restoring optimal range of motion, achieving appropriate motor control, and improving tissue quality. Reducing compensation patterns resulting from pathology or anatomical deviations is also essential. Assessment and training help identify deficits early and prevent biomechanical compensation due to constant loading.
Soft Tissue Mobilization Techniques [8:11]
Soft tissue mobilization aims to mobilize soft tissue adhesions that reduce mobility, using manual techniques like myofascial release or instrument-assisted methods. Tools like golf balls, rollers, and commercially designed instruments are used to release trigger points and bands, improving joint mobilization by addressing tight soft tissues. Foam rolling is a self-myofascial release technique that increases blood flow, tissue hydration, and decreases muscular tone, suitable for pre- or post-activity use.
Joint Mobilization Techniques [10:00]
Joint mobilization techniques are used for conditions involving joint or capsule restrictions, employing manual methods like chiropractic or Maitland techniques. Mobilization with movement involves passive movement by a therapist with bands to mobilize the joint, improving accessory motion and capsular extensibility. These techniques are important in sports rehabilitation for capsule adhesions and systemic diseases like frozen shoulder, typically used in the initial phase to reduce adhesions and achieve full range of motion.
Dynamic Mobility and Active Joint Mobilization [11:43]
Dynamic mobility involves active mobility drills to enhance range actively, incorporated into pre-warm-up routines with added weights to stabilize movement and integrate neuromuscular control. Controlled articular rotations are joint capsule stimulation techniques encouraging movement at the end range to improve joint awareness and stability, typically done towards the end of phase one of sports rehab. Resistant training in advanced stages helps achieve full range of motion, improving strength development using functional movements like squats or lunges with added weights.
Proprioceptive Training and Stretching Techniques [13:50]
Proprioceptive training enhances motor control and movement, especially post-injury, by incorporating balance and coordination drills for better joint repositioning. Stretching techniques, including dynamic stretches for warm-up and static stretches for cool-down, improve joint-specific mobility. Neural mobilization addresses neural tension through nerve glides and flossing, commonly used for sciatic and median nerve issues, especially in radiculopathies and chronic stiffness.
Vibration and Percussive Therapy [16:02]
Vibration and percussive therapy are used for recovery and pre-activation to improve joint mobility and neuromuscular facilitation. Percussive devices address specific stiffness or IT bands, commonly used in cooldowns after activity to reduce stiffness, enhance blood flow, and reduce muscle tone.
Case Scenario: Long-Distance Runner [17:18]
The lecture presents a case scenario of Naman, a long-distance runner with knee stiffness and an old ankle injury. Analysis reveals potential calf tightness affecting ankle dorsiflexion, which can be addressed with stretching exercises. Weak muscles around the ankle joint may lead to excessive pronation, requiring targeted strengthening. Structural issues or disrupted proprioceptors may also contribute to mobility issues, necessitating a comprehensive assessment and tailored interventions.
Summary [20:25]
The lecture concludes by summarizing that mobility is essential for optimal function and requires a multifaceted approach involving both manual techniques and movement. Assessment is key to individualize deficits, and exercises should be incorporated into routine training programs. Addressing mobility issues holistically, including both passive and active components, helps in injury prevention and long-term reinjury prevention, preventing biomechanical compensation patterns.
