Brief Summary:

A high number of patient with stroke develops spasticity of the upper extremity, this clinical sign of damage of 1 motoneuro (MN), causes postures and patterns of abnormal movement, due to the hyperexcitability of the MN and the rheological alterations that occur in the affected muscles. These alterations limit the use of upper extremity, restricting its use in functional activities and affecting the quality of life and social participation of the users. During the last few years the classification of the Hefter patterns for spasticity of the upper limb was created, with the end of having a common language and orienting the current therapeutic strategies oriented towards the arm.

Objective: To determine the prevalence of patterns and their impact on the quality of life of patients after a stroke.

Material and method: Descriptive design of cross section, the sample will be composed of 600 people who attend integral rehabilitation center of regions V, VIII, IX and X in Chile, that meet the inclusion criteria and sign the informed consent. The study will include a measurement made by a trained professional from each participating center using a registration form, the FIM scale and the Barthel index, to assess quality of life.

Results: It will be analyzed with the SPSS software through descriptive and inferential statistics considering the nature of the variables, all the analyzes will consider as statistically significant the results with p values less than or equal to 0.05. Depending on the interval or ordinal level of the measurements, the coefficients r of Pearson and rho of Spearman will be used to calculate the correlations.

Applicability: The results will determine the prevalence in this geographical sector, disseminate this classification and promote the use of a common language among professionals to enhance their daily work. In addition, it will allow to determine how the affectation of the upper extremity through the identification of a certain pattern alters the quality of life of the patient. This new information can be a fundamental input in the generation of future studies that seek to guide in relation to the use of therapeutic strategies in these people.


Condition or disease Intervention/treatment
Spasticity as Sequela of Stroke Stroke Upper Extremity Paresis Diagnostic Test: Evaluation Upper Extremity patterns.

Detailed Description:

The impact generated by spasticity in the performance of functional activities in post-stroke patients is undeniable. Given the above, it is essential to evaluate this construct, considering the impact it has on the ADL. There are numerous scales that allow evaluating how spasticity affects post-stroke functionality, even helping to detect which beneficial aspects of spasticity should be considered when defining a therapeutic strategy. Among the most used scales are the Barthel Index, which assesses the level of patient independence with respect to the performance of some ADL. The scientific evidence suggests that patients with spasticity have low rates in Barthel.

The scientific evidence suggests that a careful and continuous evaluation of spasticity, would allow to identify establishment times and affected structures; as well as, to recognize predictive factors that assist rehabilitation professionals, identifying which patients are predisposed to develop spasticity, in order to reduce the risk of its establishment and influence its evolution, helping to identify preventive measures and effective interventions, that allow to achieve better motor and functional results, promoting its application in search of an optimal recovery.

Given the above, the purpose of the study is to determine the prevalence of patterns and their impact on the quality of life of patients after sequelae of a stroke. The generation of new scientific evidence acquires vital importance and are key to the management of these patients.


Study Type : Observational
Actual Enrollment : 600 participants
Observational Model: Ecologic or Community
Time Perspective: Prospective
Official Title: Prevalence of Postural Patterns of Upper Extremity and Its Impact on the Quality of Life of Patients Sequelae of a Stroke.
Actual Study Start Date : June 1, 2018
Estimated Primary Completion Date : September 30, 2018
Estimated Study Completion Date : December 30, 2018

Intervention Details:
  • Diagnostic Test: Evaluation Upper Extremity patterns.
    The procedure involves evaluating subjects who meet the eligibility criteria and agree to participate in the study by signing informed consent. The study includes a measurement, applying a registration form, the Barthel scale and the FIM scale.
    Other Name: Evaluation upper extremity patterns after stroke.


Primary Outcome Measures :
  1. Clinical record [ Time Frame: 3 months ]
    Document created by the study team that seeks to collect clinical information from the sample, including the evaluation of the classification of patterns.


Secondary Outcome Measures :
  1. Evaluation of Quality of life. [ Time Frame: 3 months ]

    These will be evaluated through the:

    Barthel Index that assesses the quality of life with respect to performing ADL. The values assigned to each activity depend on the time spent and help to carry it out.

    The activities are valued differently, being able to assign 0, 5, 10 or 15 points. The global range can vary between 0, completely dependent, and 100 points, completely independent.


  2. Evaluation of functionality. [ Time Frame: 3 months ]

    These will be evaluated through the:

    Scale Functional Independence Measure (FIM) Evaluates the functional independence given through the activities of daily life (ADL). It consists of 18 items that cover two areas: motor activity (13 items) and cognitive skills (5 items). Each item is evaluated according to seven options ranging from 1 (total attendance) to 7 (total independence). The total score range goes from 18 to 126 points.



Other Outcome Measures:
  1. Spasticity evaluation [ Time Frame: 3 months ]
    Evaluation using the Ashwort Scale. This graduates the tone from 0 (no increase in tone) to 4 (rigid extremity in flexion or extension), it is based on the examiner manually moving a limb of the patient, in the whole of the possible joint range and perceive the resistance that a muscle offers when stretched.
