INTRODUCTION

DAILY LIFE
“Don't underestimate the power of your vision to change
the world. Whether that world is your office, your
community, an industry or a global movement, you need
to have a core belief that what you contribute can
fundamentally change the paradigm or way of
thinking about problems.”

THINGS TO CONSIDER
Grip Functionality
Rehabilitation Application
CAN THE APPLICATION
OF HEAVIER
WEIGHTED OBJECTS
IMPAIR THE EFFECT OF
COMMONLY USED
FRICTIONS?
OUR QUESTION
WHAT ARE THE MANIPULATIONS?
WHERE IS THE DATA?
INDEPENDENT VARIABLES
Shape
Friction
DEPENDENT VARIABLE
Subject Performance
Aim is to measure manual growth
dexterity.
PROCEDURE
•
Subject comes in to laboratory and
provided further instruction prior to
experiment.
•
They sit next to a box quite similar to
the photo listed.
•
They will be timed for a total of 30s per
trial and overall take no longer than 30
minutes for entire procedure.
•
Throughout the trials filming will be
taking place at 30 frames for data analysis
breakdown of the seven steps of BBT.
WHAT TO LEARN?
WHAT IS THE NEXT STEP?
Varying Factors
Shapes
Weights
Frictions
Subjects
Use actual patients
PRACTICAL IMPLICATIONS
In addition, therapists may vary difficulties
by using objects with high-friction or low-
friction surfaces to encourage or challenge
patients, respectively. Lastly, redesigning
daily objects by changing grip surfaces may
benefit people with sensorimotor
impairment by improving their hand grip
function and speed.
{Seo, 2012 #2}QUESTIONS?
Research conducted by Cecilia Rose Garza at Texas A&M University-Kingsville explores the impact of different object surfaces and shapes on hand grip functionality when handling heavy objects. The study aims to understand how variations in surface textures and shapes influence hand grip performance and dexterity. Practical implications include potential benefits for individuals with sensorimotor impairments. By manipulating factors like friction, weight, and shape, therapists may tailor rehabilitation strategies to enhance patients' grip strength and speed.
