1

Describing Motion Precisely

-motion may be described in many ways
-precision in terminology and language allows for better communication
-discrete serial continuous

2

Kinematics: Description of Motion

-one component of biomechanics
-includes description of motion
-no regard for production of forces

3

Kinetics: Analysis of Force

-the other component of biomechanics
-concerned with forces producing motion or maintaining equilibrium

4

Quantitative Motion Analysis

-based on quantification of data
-measures force in three planes
-more common in medical center or research settings

5

Qualitative Analysis

-defined as systematic observation and introspective judgement of the quality of human movement for the most appropriate intervention to improve performance
-low level QA offered by some: coaches, teachers, therapists
-interdisciplinary approach increased level of care
-primary method of improving function in many professions
-may be the most important skill a master clinician develops
-good qualitative analysis requires an interdisciplinary approach
-may use such models to: prevent injury in ergonomic or sport settings, monitor recovery from injury or disease processes
-by nature a subjective process, requiring a judgement call
-does not mean that it's unorganized, vague, or arbitrary
-requires extensive planning, a broad view, and many steps

6

Qualitative Analysis and Observation

-the process of gathering organizing, and assigning meaning to sensory information
-we use all our senses to treat patients

7

Qualitative Analysis and Invervention

-the use of feedback, correlations, or other changes in the environment
-goal is to improve function

8

Qualitative Analysis and Function

-term may be used interchangeably with performance (how well organism operates)
-short-term or long-term effectiveness of a person's movement in achieving a goal

9

Qualitative vs. Quantitative Analysis

-no method is purely one or the other
-qualitative end involves non-numerical analysis of movement
-quantitative end involves some measurement of function

10

Spatial Analysis

-description of body and its segments
-emphasis on position of the body and it's segments

11

Temporal Analysis

-description of body and its segments
-emphasis on sequencing of the motion of the body and its segments

12

Analyzing Qualitative Motion Analysis

-preparation
-observation
-evaluation/diagnosis
-intervention

13

Preparation

-requires a requisite knowledge base
-three main sources of information: experience, expert opinion, scientific research
-need to: establish "ideal form" or "critical features", gain knowledge of patient beforehand, continually update knowledge base

14

Observation

-process of gathering, organizing and giving meaning
-pulling in sensory information
-may "observe" human movement in many ways
-done best using a systematic observational strategy (SOS): important critical features, control of the situation, vantage points of observation, number of observations needed, decision whether extended observation will be needed

15

Common SOS

-observe according to sequence or phrase of movement
-observe from origins of movement
-observations of balance
-observe based on importance
-search for signs of sequential coordination
-gestalt approach

16

Evaluation/Diagnosis

-ascertain strengths/weaknesses of performance
-continually weigh impact of issue on the larger process
-judgement as to underlying cause of poor function
-need to narrow-->most valuable intervention
-brevity is important as to not overload patient
-rationales for prioritizing corrections to increase function: relationship to previous actions, maximizing performance, order of difficulty, correct sequence, base of support, critical features first

17

Intervention

-may involve the following
-provide the feedback to performer
-making technique changes
-other instructions to increase function

18

Effective Qualitative Analysis

-is not multidisciplinary
-is interdisciplinary
-requires integration of knowledge of sub disciplines
-weakness in any 4 parts lessens effectiveness of QA as a whole

19

Take Home Points

-quantitative and qualitative analysis are the main types of motion analysis at our disposal
-the four points of an integrated motion analysis model include: preparation, observation, evaluation/diagnosis, intervention
-most PT models include these 4 steps
-a systematic observation strategy (SOS) can help us organize and process what we see in our patients
