SP2604 - Several Concepts of Angular Kinematics and Angular Kinetics

Assignment Task

Introduction

The purpose of this laboratory report is to assess your understanding of several concepts of angular kinematics and angular kinetics taught in SP2604 module.

Motion data from a person walking over ground (gait) is being provided in the attached Excel workbook. For the analysis of the participant’s gait, you are required to calculate several kinematic and kinetic parameters, as instructed in the Methodology and Results sections below.

Use all information available to you (e.g., data in Excel sheets, instructions provided under Methodology and Results, lecture slides, images, and laboratory notes) to write a succinct and accurate “Methods” and “Results” section .

Methodology -You are required to include the following information in a Methodology section.

A methodology section, usually contains 4 parts: Participant, Equipment & Material, Protocol (Procedure), Data Processing & Analysis.

• Incorporate information provided below under relevant sections (participant, equipment & material, protocol, or data processing & analysis) to write the Methodology section.
• To each sub-section above, add information which should be retrieved and/or calculated from data available to you, and/or biomechanics textbooks (e.g., add equation used in the calculation of instantaneous velocity from a textbook and cite the source) in order to complete the Methodology section.
• Avoid using bullet points when writing The section should be written similar to the Methodology of a research paper.

Participant

• Male;
• Healthy;
• Age = 23 years;
• Mass = 3 kg;
• Height = 80 m;
• Shank length (distance measured between lateral epicondyle of femur and lateral malleolus): 42 cm

Equipment & Material

• 8-camera Qualysis motion capture system;
• Sampling Frequency of the cameras; Calculation of the SF should be shown in the highlighted area in Excel sheet called “Angles”.
• 3 Kistler force plates;
• Full-body marker set to identify major segments and joints of the body

Add information and Comment on:

• Laboratory coordinate system: g., walking mainly occurred in what cardinal plane?

Protocol (Procedure):

Data collection period: This could be obtained based on data available to you. Report time rounded to the nearest 2 decimal points.

Add information and Comment on:

• Instructions to the participant
• Direction of movement (e.g. toward laboratory origin or away from it? Along what axis?).

Data Processing & Analysis

• Data provided in the Excel workbook belongs to the right lower
• Sheet called (Angles), contains information on joint (ankle, knee, hip) rotations (angles) around the x, y, and z axes. Scroll down the page to see all data.
• Sheet called “Moments” contain moments of force (torques) about the ankle, knee and hip joints around the 3 axes (x,y,z) for the right lower Note. Scroll down the page to see all data.
• One stride of the Right lower limb (from heel strike to heel strike) happened between rows 322 and 431 of the Excel sheet and should be used for this laboratory report.
• Stance phase of the stride above contained 50 rows (Excel rows 322-371) – 45% of the stride
• Swing phase of the stride above contained 60 frames (Excel rows 372-431) – 55% of the stride length.

In the Methodology section under a (one of the four) relevant subheading stated above, add information on how the following parameters were decided and/or calculated (provide relevant formulae where required from biomechanics textbooks):

1. What two axes defined the sagittal and frontal planes for the stride above?

2. Stride length (for the one stride above)

3. Instantaneous Velocity and Acceleration values for the Ankle, Knee and Hip joints

4. Angle-Angle diagram (for Ankle-Knee)

5. Phase Plots or Phase Space (for Ankle, and Knee)

6. Continuous Relative Phase (for Ankle-Knee)

7. Curvilinear distance covered by the lateral malleolus during rotation of the knee joint through its range of motion

8. Power of the Ankle, Knee, and Hip joints in the sagittal plane for the stride above, and maximum power of Ankle, Knee, and Hip joints.

In Summary, your methodology should describe how the requested parameters 1-8 above were retrieved/calculated.
