Highly detailed summary of the content for all the OBFM Assessment lectures.
Includes work from lecture slides, textbook/reading annotations and external research where further explanation was needed.
OCCUPATION-BASED FUNCTIONAL MOTION ASSESSMENT
What is the basis for the OBFM?
Physical disabilities cause limitations in performance skills – occ enablers
o including ROM, muscle strength and motor control
Which cause deficits in performance in all areas of occupation
What is Occupation-Based Functional Motion Assessment?
Way of assessing ROM, muscle strength and motor control available for
completion of tasks
By observing the client during performance of functional occupations
o Work
o Leisure
o Personal and Community Living (ADL and IADL)
o Learning
o Play
o Social interaction
In a variety of context and environments
Primary responsibility of the OT is to assess occupational performance
Identify limitations and plan interventions to address
Therefore, limitations should first be assessed through observation of functional
activities.
What is the difference between formal ROM assessment VS occupation-based functional
motion assessment VS functional motion assessment?
Formal ROM assessment
o Goniometer is used to measure ROM at a particular joint
Occupation-based functional motion assessment
o has the advantage of added resistance on body structures that will occur
as a result of using equipment
o i.e., sliding door, manipulating objects, or resisting fatigue and having
endurance during repetitive activities such as bouncing a ball
o occurs in engagement with an activity
Functional motion assessment is just a functional motion assessment
o i.e., assessment through observation
What is the purpose of the observation in the OBFM?
To understand the client’s occupational performance limitations in the context of
the interaction between:
o The person
o The task
o The environment
What are questions that can be used to guide the clinical observation?
Does the client have adequate ROM to perform the task?
o Where are the joint limitations?
o What are some of the possible causes of the limitations?
o True ROM limitations or caused by decreased muscle strength?
Does the client have enough strength to perform the task?
o In which muscle group is there apparent weakness?
o If the strength appears inadequate to perform the task because the client
cannot complete the ROM required is there truly muscle weakness or is
there actually limited ROM?
, How does the OBFM relate to formal assessment?
OBFM results may indicate need for formal assessment of occupational enabler
Order of assessment

o Formal assessment
Explain the Hip complex within the OBFM context
Functions of the hip joint include
Supporting weight of the body
Hip movement makes it possible
o To move the body closer to or away from the ground
o Bring the foot closer to the trunk
o Position the lower limb in space
In functional activities, lumbar-pelvic movements accompany hip movement –
extending the functional capabilities of the hip joint
What are the movements of the hip complex?
Flexion and extension
o Standing requires full hip extension
o Nearly full hip flexion is required for:
Squatting to tie a shoelace with the foot on the ground
Foot care done with the foot on the edge of a chair
o Moderate to full hip flexion and extension:
Donning shoes and socks
Bathing the feet in a bathtub
Ascending / descending stairs or a step stool
Sitting and rising from a chair
Riding a bike
Abduction and adduction
o Ordinary ADL’s do not require full ranges of ab- and adduction of the hip
Loss of full range of hip ab- and adduction may not impact ADLs
o Main function of hip ab and adductors: keeping pelvis level when one foot
is off the ground.
o Hip abduction is needed for:
Stepping sideways into a shower or bathtub
Donning trousers while sitting
Squatting to pick up an object
