Summary OBFM Assessment

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 OBFM
o Functional motion 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
