02 lecture mt 9-s-15 'basics in manual therapy-1' by abdul ghafoor sajjadriphah college of rehabilitation sciences
This document provides an overview of spinal movements and manual therapy concepts. It discusses the mobile segment of the spine and spinal range of motion. It describes three-dimensional joint positioning including open pack, close pack, and resting positions. Bone and joint movements including rotations, translations, traction, compression and gliding are explained. The concave-convex rule for determining glide direction is covered. Treatment planning and concepts such as abnormal roll-gliding are also summarized.ย
Joint Function.pptx
The document discusses the structure and function of human joints. It describes two types of joints: synarthrodial joints which primarily provide stability and diarthrodial joints which primarily provide mobility. It also discusses kinematic chains, describing open chains where movement at one joint is independent and closed chains where movement at one joint causes movement in other joints to maintain stability. The document further discusses range of motion, osteokinematics (bone movement), and arthrokinematics (joint surface movement types like roll, slide, and spin).
Geoff Verrall Hamstring Injury Symposium presentation part 1
This document discusses hamstring muscle injuries, their mechanisms, and implications for rehabilitation and prevention. It begins by outlining the biomechanics of the gait cycle and how forces are applied during the stance phase of sprinting. Specifically, it notes that a hamstring strain requires the muscle to be lengthening with a tug of war between its attachment points. The most common injuries involve the proximal tendons of the biceps femoris muscle during non-stance hip flexion or knee extension. Prevention strategies aim to decrease forces on the hamstring during lengthening through proper sprint technique and training specificity. Rehabilitation focuses on early motion and addressing muscle imbalances through stretching.
Orthosis
An orthosis is an external device that is applied to the body to improve function, provide support, reduce pain, correct deformities, and prevent progression of fixed deformities. Lower limb orthoses include foot orthoses, ankle-foot orthoses, knee orthoses, knee-ankle-foot orthoses, and hip-knee-ankle-foot orthoses. The goals of lower limb orthoses are to maintain or correct body segment alignment, assist or resist joint motion, provide axial loading and relieve distal weight bearing forces, and protect against injury. Orthoses can be static devices that hold body parts in position or dynamic devices that facilitate motion.
Goniometry
Goniometry refers to the precise measurement of joint angles using instruments such as a universal goniometer. Goniometric data is used to determine impairment, establish diagnoses, develop treatment plans, and evaluate progress. Joint motion includes arthrokinematics (gliding and spinning of joint surfaces) and osteokinematics (bone movements). Range of motion is measured in three planes (sagittal, frontal, transverse) using instruments properly aligned with bony landmarks. Both active and passive range of motion are measured to evaluate joint integrity and flexibility. Restricted or increased range of motion can indicate conditions like capsular patterns of hypomobility or generalized hypermobility.

Lifetime Fitness: Ch 5
This chapter discusses flexibility, different types of stretching, and recommendations for an effective warm-up and cool-down routine. It defines flexibility and describes how it declines with age. There are three main types of stretching: static, ballistic, and PNF. Static stretching involves holding a stretch for an extended time and is best after a workout. Ballistic stretching uses bouncing motions and should be done before a workout. PNF stretching is the most effective but requires a partner. A dynamic warm-up should last 10-15 minutes and gradually increase intensity through movements like walking lunges and jumping jacks. Stretching should be included at the end of each workout for muscle recovery and improved flexibility.
Peripheral joint mobilization
The document discusses peripheral joint mobilization and manipulation techniques. It defines these techniques as passive manual therapy applied to joints to address range of motion limitations from altered joint mechanics. The techniques can be non-thrust oscillations or sustained distraction, or high-velocity thrusts applied at the end of available motion. Proper positioning, stabilization, and application of specific sliding forces are described to safely stretch tight joint capsules while avoiding compression. The effects of increased motion on joint health are also summarized.

Range of motion in yoga asanas
Range of motion (ROM) refers to the distance and direction a joint can move. Each joint has a defined ROM expressed in degrees. Flexion decreases a joint angle while extension returns it to normal position. Hyperextension moves beyond the angle. ROM is limited by surrounding tissues and joint health. Exceeding ROM can cause injury. ROM exercises preserve flexibility and come in passive, active, and assisted forms. Lotus pose requires significant hip flexion, external rotation, and abduction along with ankle dorsiflexion. Knowledge of ROM is important for safe yoga practice and adjustment.
Mobilization
Joint mobilization is a manual therapy technique used to modulate pain, increase range of motion, and treat joint dysfunctions. It involves passive movement of joints and surrounding soft tissues at varying speeds and amplitudes. There are 5 types of joint movement - roll, slide, spin, compression, and distraction. Mobilization techniques are graded based on amplitude and location within the range of motion. Lower grades are used for pain modulation while higher grades aim to increase mobility. Proper positioning, stabilization, direction, and patient response are important considerations when applying mobilization.
Transfemoral protheses
This document discusses transfemoral prostheses. It begins with an introduction to transfemoral amputation, which is the amputation of the leg between the knee and hip. It then covers the rehabilitation process for individuals with a transfemoral amputation, including exercises and management of the residual limb. Finally, it describes the components of transfemoral prostheses, including different socket designs, suspension methods, knee and foot options. The goal of rehabilitation and prosthetic training is to help individuals regain mobility and independence.
TENDON TRANSFER-WPS Office_WPS PDF convert-converted.pptx
Tendon transfer is a surgical procedure that involves moving the insertion of a tendon from its original attachment site to a new location. This allows a muscle to perform a different function. There are several types of tendon transfers classified by whether they restore power or position. Common indications include muscle paralysis, imbalance, or ruptured tendons. Some key principles are that the donor muscle must have adequate strength and excursion. Post-operatively, immobilization and rehabilitation exercises are used to strengthen the muscle in its new role.
Proprioception
During limb movement and changes in position, the tissues around the relevant joints will be deformed, including skin, muscles, tendons, fascia, joint capsules, and ligaments
All these tissues are innervated by mechanically sensitive receptors, and their density varies across muscles and regions of the body
Muscle spindles play the major role in kinesthesia, with some skin receptors providing additional information
Golgi tendon organs contribute to proprioception, including the senses of force and heaviness

This document discusses biomechanics models of human movement. It describes three schools of biomechanics: the inverted pendulum model from 1685, the spring-mass model from 1989/1990, and the integrated spring-mass model from 2012. The spring-mass model views the leg as a spring and torso as mass, while the integrated model also includes the spine and models the legs as progressive rate torsion springs. The document argues the integrated model better explains how the human body absorbs shocks and stores energy for efficiency. It also discusses how nervous system modulation, movement patterns, fatigue and other factors can impact spring stiffness and compliance in the human body.

Basic ap chapter 11 powerpoint 2017
The muscular system allows for movement of the body through contraction of skeletal muscles, which are attached to bones via tendons. There are two main types of skeletal muscles - the diaphragm and intercostal muscles, which facilitate breathing by changing the size of the thoracic cavity. During inhalation, the diaphragm contracts and flattens while the external intercostals elevate the ribs, expanding the cavity. Exhalation occurs when these muscles relax and the internal intercostals draw the ribs together to decrease cavity size.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

- 3. 1. LEVER โข Levers are simple machines consisting of rigid structures rotating about a fixed axis. โข It has 3 components i. Effort/force ii. Load/resistance iii. Fulcrum/axis โข By changing the position of fulcrum Levers are used in 3 mechanical advantages more commonly Called classes of levers.
- 4. 1st class levers 2ndclass levers 3rd class levers Fulcrum lies btw load & effort Load lies btw fulcrum & effort Effort lies btw fulcrum & load Mechanical advantage=1 Mechanical advantage >1 Mechanical advantage <1 Examples Examples Examples
- 6. 2. ARTHROKINEMETICS โข Arthro = joint kinematics= study of motion โข Arthrokinemetics are defined as joint surface motions, also know as joint play motions and accessory movements. โข Involuntary โข Necessary for full joint ROM โข Cant be seen, only felt โข Roll ๏ knee โข Glide ๏ MCP โข spin ๏ radius โข Most of the joints have rolling and gliding simultaneously ๏ ball & socket
- 7. 3.OSTEO KINEMATICS โข Osteo= bone kinematics= study of motion โข Defines as Movement between 2 bones also known as physiological movements โข voluntary โข Rotation around the axis in a specific plane โข Clearly visible โข Flexion/extension ๏ sagittal plane โข Abduction/adduction ๏ frontal/coronal plane โข Circumduction ๏ includes all motions โข Need intact accessory movements to complete the ROM
- 8. 4.CONVEX-CONCAVE RULE โข Convex-concave rule describes relationship between arthrokinematics and osteokinematics โข Convex rule ๏ When moving joint surface is convex, the roll and glide occur in the opposite direction. โข Concave rule ๏ When moving joint surface is concave, the roll and glide occur in the same direction
- 10. 5.CAPSULAR POSITIONS Loose pack position Closed pack position Minimal stress Maximal stress Lax ligaments Tight ligaments Separated joint surface Compressed joint surface
- 11. 6. END FEEL โข Defined as Quality of movement or resistance felt at the end of PROM โข Gives information about Type of structure that limits ROM Physiological Pathological 1. Soft โ soft tissue approximation e.g. knee flexion 1. Springy --pain causes rebound 2. Firm --muscular, capsular ligament approximation e.g. hip flex with straight knee, MCP extension with supinated forearm 2. Empty --no resistance found due to pain inhibiting movement before end range 3. Hard โ bony approximation e.g. Elbow extension 3. Boggy --edema, swelling
- 12. 7. CAPSULAR PATTERN โข Proposed by Cyrix. โข Defined as Particular pattern of restrictions involving entire joint capsule caused by pathological conditions. โข Each joint has specific pattern of limitation โข While irritation to structures outside the capsule do not follow same pattern hence called Non-capsular pattern of movement restrictions โข Classified by Cyrix into 3 categories i. Ligamentous ii. Internal derangement iii. Extra-articular lesion
