Due to acquired brain injury (ABI), is often difficulty in gait and balance alterations, as problems that patients designated as the most disabling. It is essential to an effective assessment of the balance.

Objective: The purpose of the present project adapt and verify the validity of the scale Community Balance and Mobility (CB&M), in patients with ABI in subacute and chronic stage, since that is postulated as a brief tool and covering the peculiarities of the specific alterations of the patient after suffering brain injury.

Methodology: Between February 2021 and June 2022 will be transcultural adaptation to the ABI population and validation of psychometric scale CB&M in three phases. 100 subjects who receive treatment in centers of attention to brain injury in Spain will be recruited.

Results: validity and reliability parameters shall be calculated by means of descriptive statistics for each item of the scales and the set of scale score. Investigators will also analyze the internal consistency using Cronbach's alpha, the interclass correlation coefficient will be used to determine the reliability, and the items will be scanned with the Pearson coefficient: > 0.20, among other parameters.


Cristina Lirio-Romero et al., will develop a cross-cultural adaptation to the Spanish population with Acquired Brain Injury (ABI) and psychometric validation of the Community Balance and Mobility (CB&M) scale. The author of the scale has consented the adaptation of the scale. The study will take place at several centers of attention to brain injury in Spain. After receiving the approval of the Ethics and Clinical Research Committee of the University of Alcal (Madrid), it is proposed to implement the study between February 2021 and June 2022. A minimum of 100 adults, aged between 18 and 65, will be recruited subacute or chronic state after suffering brain injury. The sample size conforms to COSMIN recommendations.

After verifying that there are no parallel studies on the subject in progress, the possible participants will be informed of the development of the investigation (ANNEX 1), who must sign the informed consent (ANNEX 2) before being recruited into the study. In addition, a coding sheet (ANNEX 3) of the participants will be filled in so that from now on the data related to the proper name does not appear but with a number that ensures the protection of their data.

Selection criteria to enter to participate in the study will be: adults who had suffered a ABI at least 2 months ago, that their disability before suffering it was less than or equal to three on the scale modified by Rankin, who have an absence of cognitive impairment according to the Minimental State Examination scale, that is, a score in it greater than 24, without previous diseases that alter the balance, that were clinically stable and without fever, with the ability to walk with help technical or without it, and that they gave their informed consent.

On the other hand, those people with medical contraindications for physical tests (acute musculoskeletal or peripheral nervous system disorders), who did not understand the instructions, severe aphasias or with subjects with acute processes of any added pathology will be excluded.

The study was developed in 3 phases:

Phase 1: Transcultural adaptation process. Phase 2: Pre-Test: collected , as well as the ease of interpretation of the results.

Phase 3: Psychometric validation process.
