    <textblock>
      This study aims to examine the effect of external, internal and no attention focus walking&#xD;
      training during gait rehabilitation on real-time conscious motor processing (reinvestment),&#xD;
      balance, walking ability and fear of falling by older adults at risk of falling in Hong Kong.&#xD;
&#xD;
      One-hundred and eight older adults will be recruited from elderly community centers in Hong&#xD;
      Kong. Participants will be randomly assigned into 3 groups (i.e., No Attention Focus Walking&#xD;
      Group (NAFWG; active control group, n=36), an External Attention Focus Walking Group (EAFWG,&#xD;
      n = 36) or an Internal Attention Focus Walking Group (IAFWG, n = 36)). Participants in&#xD;
      different groups will have training sessions (about 45 minutes each) three times per week for&#xD;
      4 weeks in a group of 6 participants. A total of 12 sessions will be completed by each&#xD;
      participant.&#xD;
&#xD;
      All training sessions will be conducted by experienced registered physiotherapists in Hong&#xD;
      Kong and a research assistant with experience in exercise training for older adults. In each&#xD;
      training session, all groups will have warm-up (5 minutes), balance training (5 minutes),&#xD;
      body transport training (5 minutes), body transport with hand manipulation training (5&#xD;
      minutes), walking training with various levels of difficulties in a 40-meter walkway with&#xD;
      different instructions in different walking groups (20 minutes) and cool down (5 minutes).&#xD;
      For the walking training (20 minutes), all participants will be invited to conduct walking&#xD;
      training on a walking field with an area of 25 meter square and a total walking distance of&#xD;
      about 40 meters for each walking trial from cone 1 to 9. Two screens that connected with a&#xD;
      laptop computer will be positioned 1 meter beside the walking field. Both screens will be&#xD;
      projected different digits from 0 to 9 randomly in the speed of 2 seconds per digit.&#xD;
      Participants in the NAFWG, EAFWG, and IAFWG will receive different instructions during&#xD;
      walking training.&#xD;
&#xD;
      Each participant will complete assessment sessions (total 3 assessment sessions) before&#xD;
      training at baseline (T0), just after completion of all training sessions (T1) and 6 months&#xD;
      after completion of all training sessions (T2). In the baseline assessment (T0), a structural&#xD;
      questionnaire will be used to ask for demographics, medical history, detailed history of fall&#xD;
      incident, social history and social economic status of all participants. A battery of&#xD;
      assessments will be conducted to assess physical and cognitive abilities of the participants&#xD;
      in all assessment sessions (T0, T1, &amp; T2). Walking ability will be assessed by the 10 meters&#xD;
      comfortable and fast walking speed (Bohannon, 1997). Functional balance and gait assessment&#xD;
      will be done by the Tinetti Balance Assessment Tool (Tinetti, 1986), the Berg Balance Scale&#xD;
      (BBS) (Berg et al., 1989) and the Timed 'Up &amp; Go' Tests (TU&amp;G) (Podsiadlo &amp; Richardson,&#xD;
      1991). Cognitive function will be evaluated by the Chinese version Mini-Mental State&#xD;
      Examination (MMSE-C) (Folstein et al., 1975; Chiu et al., 1994). The Chinese version of the&#xD;
      Fall Efficacy Scale International (FES-I (Ch)) (Kwan, Tsang, Close &amp; Lord, 2013) will be&#xD;
      completed to assess the fear of falling. The Chinese version Movement Specific Reinvestment&#xD;
      Scale (MSRS-C) (Masters et al., 2005; Wong et al., 2015a; Wong et al., 2015b) will be&#xD;
      administered to examine the conscious motor processing propensity (i.e., movement specific&#xD;
      reinvestment). The alpha2 EEG coherence between T3 (verbal-analytical region of the brain)&#xD;
      and the Fz (motor planning region of the brain) (i.e., T3-Fz EEG coherence) of all&#xD;
      participants when walking at the 6-meter level-ground walkway (three walking trials) will be&#xD;
      determined to identify the real-time conscious motor processing propensity (Zhu et al., 2011;&#xD;
      Ellmers et al., 2016; Chu &amp; Wong, 2019). All participants will be equipped with EEG&#xD;
      electrodes before the start of the three walking trials. EEG activity will be received using&#xD;
      a wireless EEG device (Brainquiry PET 4.0, Brainquiry, The Netherlands) and will be recorded&#xD;
      using the real-time biophysical data acquisition software (BioExplorer 1.5, CyberEvolution,&#xD;
      US). Previous research has demonstrated that alpha2 (10-12Hz) T3-Fz EEG coherence is&#xD;
      sensitive at detecting within-subject changes in real-time conscious motor processing&#xD;
      propensity during a postural sway task (Ellmers et al., 2016). T4-Fz EEG coherence will be&#xD;
      utilized to identify whether the changes in the alpha2 T3-Fz EEG coherence will be due to&#xD;
      global activation of the brain. The EEG electrodes are non-invasive and will not be used in&#xD;
      any diagnostic purpose.&#xD;
&#xD;
      All participants will be asked to record their number of falls prospectively at the time&#xD;
      between T1 (completion of all training sessions) and T2 (6 months after completion of all&#xD;
      training sessions) using a structural calendar. The number of falls within the 6-month&#xD;
      follow-up period will then be collected.&#xD;

This study aims to examine the effect of external, internal and no attention focus walking
      training during gait rehabilitation on real-time conscious motor processing (reinvestment),
      balance, walking ability and fear of falling by older adults at risk of falling in Hong Kong.

      One-hundred and eight older adults will be recruited from elderly community centers in Hong
      Kong. Participants will be randomly assigned into 3 groups (i.e., No Attention Focus Walking
      Group (NAFWG; active control group, n=36), an External Attention Focus Walking Group (EAFWG,
      n = 36) or an Internal Attention Focus Walking Group (IAFWG, n = 36)). Participants in
      different groups will have training sessions (about 45 minutes each) three times per week for
      4 weeks in a group of 6 participants. A total of 12 sessions will be completed by each
      participant.

      All training sessions will be conducted by experienced registered physiotherapists in Hong
      Kong and a research assistant with experience in exercise training for older adults. In each
      training session, all groups will have warm-up (5 minutes), balance training (5 minutes),
      body transport training (5 minutes), body transport with hand manipulation training (5
      minutes), walking training with various levels of difficulties in a 40-meter walkway with
      different instructions in different walking groups (20 minutes) and cool down (5 minutes).
      For the walking training (20 minutes), all participants will be invited to conduct walking
      training on a walking field with an area of 25 meter square and a total walking distance of
      about 40 meters for each walking trial from cone 1 to 9. Two screens that connected with a
      laptop computer will be positioned 1 meter beside the walking field. Both screens will be
      projected different digits from 0 to 9 randomly in the speed of 2 seconds per digit.
      Participants in the NAFWG, EAFWG, and IAFWG will receive different instructions during
      walking training.

      Each participant will complete assessment sessions (total 3 assessment sessions) before
      training at baseline (T0), just after completion of all training sessions (T1) and 6 months
      after completion of all training sessions (T2). In the baseline assessment (T0), a structural
      questionnaire will be used to ask for demographics, medical history, detailed history of fall
      incident, social history and social economic status of all participants. A battery of
      assessments will be conducted to assess physical and cognitive abilities of the participants
      in all assessment sessions (T0, T1, & T2). Walking ability will be assessed by the 10 meters
      comfortable and fast walking speed (Bohannon, 1997). Functional balance and gait assessment
      will be done by the Tinetti Balance Assessment Tool (Tinetti, 1986), the Berg Balance Scale
      (BBS) (Berg et al., 1989) and the Timed 'Up & Go' Tests (TU&G) (Podsiadlo & Richardson,
      1991). Cognitive function will be evaluated by the Chinese version Mini-Mental State
      Examination (MMSE-C) (Folstein et al., 1975; Chiu et al., 1994). The Chinese version of the
      Fall Efficacy Scale International (FES-I (Ch)) (Kwan, Tsang, Close & Lord, 2013) will be
      completed to assess the fear of falling. The Chinese version Movement Specific Reinvestment
      Scale (MSRS-C) (Masters et al., 2005; Wong et al., 2015a; Wong et al., 2015b) will be
      administered to examine the conscious motor processing propensity (i.e., movement specific
      reinvestment). The alpha2 EEG coherence between T3 (verbal-analytical region of the brain)
      and the Fz (motor planning region of the brain) (i.e., T3-Fz EEG coherence) of all
      participants when walking at the 6-meter level-ground walkway (three walking trials) will be
      determined to identify the real-time conscious motor processing propensity (Zhu et al., 2011;
      Ellmers et al., 2016; Chu & Wong, 2019). All participants will be equipped with EEG
      electrodes before the start of the three walking trials. EEG activity will be received using
      a wireless EEG device (Brainquiry PET 4.0, Brainquiry, The Netherlands) and will be recorded
      using the real-time biophysical data acquisition software (BioExplorer 1.5, CyberEvolution,
      US). Previous research has demonstrated that alpha2 (10-12Hz) T3-Fz EEG coherence is
      sensitive at detecting within-subject changes in real-time conscious motor processing
      propensity during a postural sway task (Ellmers et al., 2016). T4-Fz EEG coherence will be
      utilized to identify whether the changes in the alpha2 T3-Fz EEG coherence will be due to
      global activation of the brain. The EEG electrodes are non-invasive and will not be used in
      any diagnostic purpose.

      All participants will be asked to record their number of falls prospectively at the time
      between T1 (completion of all training sessions) and T2 (6 months after completion of all
      training sessions) using a structural calendar. The number of falls within the 6-month
      follow-up period will then be collected.
