The core function of cognitive training will be including attention, recognition, color and shape identification, calculation, visual perception, visuospatial processing and executive function. Participants will perform tasks designed to enhance abovementioned types of cognitive functions. The difficult level of this training program will be adjusted automatically and continuously based on each participant's level of performance. Cognitive training group will use commercialized cognitive based training programs to facilitate several cognitive functions. The core function will be including attention, recognition, color and shape identification, calculation, visual perception, visuospatial processing and executive function. Participants will perform tasks designed to enhance abovementioned types of cognitive functions. The difficult level of this training program will be adjusted automatically and continuously based on each participant's level of performance.

At the first time in guiding training will focus on introducing the Goal-Plan-Do-Check strategy and identifying initial three goals by the Canadian Occupational Performance Measure. At the second time in guiding training will begin with a review of the Goal-Plan-Do-Check and will apply the Goal-Plan-Do-Check to the first initial goal. Participants will review this goal and plan, describe the execution of the plan (do), and evaluate the execution of the plan (check). After each execution of the plan, the participant will rate his performance using the COPM Performance Scale, producing iterative scores for each activity. The remaining session of guiding sessions will repeat this process, review performance of identified activities, and applying the Goal-Plan-Do-Check strategy to improve performance.

The TMT is a neuropsychological test of visual attention and task switching. It consists of two parts (TMT-A and TMT- B) in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. The Chinese version of the TMT has been suggested to be a reliable instrument for measuring executive function among older adults. The scores for both TMT A and B are reported as the number of seconds required to complete the task. According to the TMT directions for administration, an average score for the TMT Part A is 29 seconds and a deficient score is greater than 78 seconds. For the TMT Part B, an average score is 75 seconds and a deficient score is greater than 273 seconds. Therefore, higher scores reveal greater impairment.

The 6MWT measures the maximum distance walked over 6 minutes, which assess the endurance and mobility level of the participants. The participants could rest as needed during the course of the test. The test-retest reliability and responsiveness has been established to be high for patients with chronic stroke (Fulk, Echternach, Nof, & O'Sullivan, 2008).

The 30 second chair stand test (CST) will be assessed to indicate the strength and endurance level of the lower extremities. The participants will be asked to stand up from a standardized chair and then sit down as many times as possible within 30 seconds. The feasibility and reliability of using CST in people with cognitive impairment have been established to be good (Blankevoort et al., 2013).

The Berg balance scale is a test of a person's static and dynamic balance abilities. This scale comprises a set of 14 simple balance related tasks, ranging from standing up from a sitting position, to standing on one foot. The degree of success in completing each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all scores. The range of score is 0-56 and a below average score indicates a high risk for falls. Excellent test-retest reliability has been reported in acquired brain injury.

We will evaluate isometric knee flexors and extensors muscle strength using handheld dynamometer. The participant will be seated upright in a chair with back support, the knee will be placed in 90-degree flexion and the evaluator will stabilize the thing to eliminate synergistic movements. Participants will be asked to perform a maximal isometric contraction of knee flexion and extension with affected and less affected side. We will record the mean value of 3 attempts.

An objective measure of the amount of arm movements in real-life situations will be provided by the accelerometers. Actigraphy activity monitors (ActiGraph, Shalimar, FL, USA) will be worn on participants' wrists for 3 consecutive days before and after training to measure the number of moves each minute, and the average counts of move per minute. The participants will be asked to wear the device during the day and data recorded by the actigraphy will be analyzed with the MAHUFFE software (http://www.mrc-epid.cam.ac.uk/). The use of actigraphy has been validated for patients with TBI.

The TUG assesses the dynamic balance ability and mobility. The participants will be required to stand up from a chair, walk 3 meters, turn around, walk back to the chair, and sit down. The test-retest reliability of TUG on individuals with stroke was excellent (Ng & Hui-Chan, 2005).

The FIM assesses the dependence level of individuals with stroke to perform 18 activities (13 motor and five cognitive tasks) in daily living. The score ranges from 18 to 126 and higher scores demonstrate greater independent participation in daily activities (Ottenbacher, Hsu, Granger, & Fiedler, 1996). The FIM has good interrater reliability and validity (Hsueh, Lin, Jeng, & Hsieh, 2002).

The AM-PAC assess difficulties in daily participation with 58 items containing the following aspects: physical functioning, self-care, daily routine, communication, and interpersonal interaction. The items and scoring system are adopted from the ICF framework. The AM-PAC has adequate reliability and validity. There are three specific functional domains: basic mobility(score range=18-72), daily activity(score range=15-60) and applied cognitive(score range=19-76). For each subtest, a higher score indicates better performance.

The PM-3D4D includes 24 items measuring participation in productivity(6 items), social(12 items), and community(6 items) domains across 4 dimensions: diversity of participation(Y/N), frequency of participation(0-6), desire for change(Y/N), and difficulty in participation(1-4). The score of diversity of participation is percent of the number of items in which a person answered yes divided by the total number of items within each domain. The score of frequency of participation is sum of the ratings divided by the total number of items within each domain. The score of desire for change is percent of the number of items in which a person answered yes divided by the total number of items within each domain. The score of difficulty in participation is total score within each domain. The PM-3D4D has been shown adequate reliability and validity in rehabilitation patients.

The GAS assesses the extent to which patient's individual goals are achieved in the course of intervention. The GAS has been shown responsive to the change in cognitive rehabilitation. It used to quantify the extent to which treatment goals were achieved. Individual goals were evaluated in a standardized way, using predefined levels of achievement based on current and expected performance. A 5-point Goal Attainment Scale was used: the baseline level (-2), partial achievement (-1), the expected level of achievement (0), small better than expected levels (1), remarkably better than expected levels(2).

The Beck depression inventory is a self-report measure of depression severity. Excellent reliability and validity have been established in patients with TBI. The BDI-II contains 21 questions, each answer being scored on a scale value of 0 to 3. The range of score is 0-63 and higher total scores indicate more severe depression.
