5. Identify and describe two tools of measurement in functional anatomy. Two commonly used tools to obtain anthropometric measures are x-ray and goniometers. X-rays and other radiological techniques aid in showing bones structure and mass in vivo. This is possible due to x-rays passing unobstructed through low density tissues and being obstructed by high density tissues. Goniometers are a tool used to measure the range of motion of a joint. This helps identify the plane of movement through…

Altering support surface is an effective technique for balance training. A variety of balance boards (also called wobble board or ankle disc) is commonly used as one of the devices for rehabilitation program to facilitate neuromuscular control. Literature have shown that exercising under unstable condition can regain muscle activity [1–3], muscle onset latency [4], proprioception [5–7], and balance [8–10]. Although training with balance board can conduct by double or single leg, one- foot…

Lagrangian configurations When a continuum is in motion, its velocity, stress tensor or other physical or kinematic properties may change with time. In another words, a physical property or a kinematic property of the body can be expressed in terms of a reference coordinate system if we consider that property as a function of its location on the spatial coordinates and time. Meanwhile, where this reference…

IV. Mechanical analysis for the manipulator arm In this section, the static analysis, forward kinematics and inverse kinematics for the manipulator arm will be discussed. A. Static Analysis The static analysis is very significant in manipulator’s design to roughly approximate the required torques from each motor. In our design, it is important to check the stability of the quadcopter that the manipulator is integrated on it in terms of manipulator arm center of mass shifting as function of…

There are many student athletes all over the United States that have torn their anterior cruciate ligament (ACL). Sports like football, basketball, wrestling, and soccer are constantly shifting left and right and jumping give making them a higher risk for a ACL injury or minor knee injury than an average young adult. After the knee injury these young athletes need to go through some kind of rehab to get back on the field and to their everyday life activities. During the time of rehab they will…

The articulatory kinematic approach has received significant attention due to its focus on motor programming and planning. The nature of this treatment is designed to increase correct production of sounds by guiding clients to proper movement and placement of the articulators (Wambaugh & Mauszycki, 2010). Specific strategies employed during articulatory kinematic therapy include modeling, repetition, articulatory placement and tactile cueing…

In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…

the ball catcher and the final velocity of the system? Additional question: What is the percentage error of the initial velocity calculated using momentum and kinematics? Percentage error between theoretical initial velocity and experimental initial velocity? How much energy is lost? note: the initial velocity calculated using kinematics should equal to the initial velocity calculated using momentum, meaning the initial velocity in apparatus 1 should equal to the initial velocity on…

most of the weight is put. The golf shaft is the most important part of a golf club. There are two sets of measurements in a golfers swing with each club. The first measurement is the joint angles and feet/ ball orientation of the golfer. The body kinematics during the swing from take away when you swing up to ball impact when you hit it. And the second measurement is swing characteristics and ball dynamics, the club heads speed, ball speed, clubface angle, swing path angle, impact point,…
