What is the purpose of Assessments?

What is the purpose of Assessments?

To gather information about the person, the occupations that concern them and the environments in which the occupations occur. It is analysed and interpreted to identify person, environment and or occupational factors that underlie the clients occupational issue

Define Bottom-Up Assessment Approach

Focuses on performance components and impaired skills to understand persons abilities and limitations. It suggests that body functions and structures support occupational performance and by improving impaired skill or ability there will be a corresponding improvement in occupational performance. Assesses components of function such as strength, tone, range of motion, balance

Use of grading and manual guidance

Explain Constraint Induced Movement Therapy (CIMT)

Involves the restraint of the unaffected limb to increase use of the affected limb. Aim is to discourage "learned non-use". Mass practice is for 2 weeks wearing restraint for 6 hours day on unaffected side although you must consider the patients cognition, support and safety

Explain Functional Electrical Stimulation (FES)

Electrical stimulation is a technique that uses short bursts of electrical pulses to generate muscle contraction by stimulating motor neurons or reflex pathways. Peripheral nerve pathways must be intact for contraction to occur. It can be used to improve motor recovery, reduce pain and spasticity, strengthen muscles and increase ROM
