Stroke
Conditions
Brief summary
The sit-to-stand and dynamic weight-shifting ability of stroke patients is highly associated with walking performance. Therefore, in order to improve the dynamic weight-shifting ability in sit-to-stand and parallel or tandem standing, a real-time visual or auditory feedback is used in our design to allow patients to realize the weight-bearing condition (by using load cells) in both sound and affected legs immediately. It can help patients to learn to control muscle to shift weight effectively which will improve patients' walking performance. By integrating physical therapy planning with electro-mechanical technology, the goal of this study is to develop a standing balance training system by requiring patients to control their center of pressure (COP) in performing sit-to-stand and maintain a standing posture via the use of their core and lower extremity musculature.
Detailed description
1\. Written informed consent must be obtained before any study specific procedures are undertaken. 1. For healthy group: Participants will be recruited from the staffs and students in Kaohsiung Medical University (including Learning University), and healthy families of CVA patients in the university affiliated hospital. 2. For stroke (CVA) group: We will ask the physical therapists in the university affiliated hospital to nominate the potential CVA participants . The physicians will determine if they would meet the inclusion criteria before participating the present study. 2\. The process of the experiment (brief describe) 1. Written informed consent must be obtained before any study specific procedures are undertaken. 2. Subjects who are recruited to participate in this experiment should provide the personal information forms first (ex: sex, age, height, weight, post-stroke duration, stroke type, hemiplegic side, ambulation devices etc.). Then, assessment (PASS, Berg Balance Scale, Timed Up and Go) will be conducted by a physical therapist at baseline. 3. While the stroke patients after completing the 4 -times, and 8-times training program, the above-mentioned assessment conducted again by the same physical therapist. The healthy will not receive balance training, thus .only receive one assessment.
Interventions
BEHAVIORALBalance function, gait ability, weight- distribution and weight-shifting
Healthy adults and stroke patients accepted two measurements within a week. Balance function, gait ability, weight- distribution and weight-shifting during sit-to-stand, quite standing, and weight-shifting toward the forward foot.
BEHAVIORALWeight- distribution and weight-shifting training program
The stroke patients received a weight-shifting training program , 30 minutes/time, 2-5 days a week for 2-3 weeks(8 sessions). After training, they accepted a post-test within a week.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in performance of weight distribution after 8 sessions intervention | The assessments will be conducted before and after intervention (4 Weeks, 8 Sessions) | By using the force plate to record the ground reaction force and then to obtain weight distribution while performing the sit to stand activity |
| Changes in performance of standing balance after 8 sessions intervention | The assessments will be conducted before and after intervention (4 Weeks, 8 Sessions) | By using the force plate to obtain displacements of the center of pressure (COP) while standing and weight transfer |
| Changes in performance of static and dynamic balance after 8 sessions intervention | The assessments will be conducted before and after intervention (4 Weeks, 8 Sessions) | By using the Postural Assessment Scale of Stroke (PASS) to assess and monitor postural control. The PASS consists of 2 sections with a 4-point scale to describe each task. The total score ranges from 0 - 36. |
| Changes in performance of balance function after 8 sessions intervention | The assessments will be conducted before and after intervention (4 Weeks, 8 Sessions) | By using the Berg Balance Scale to assess balance function. It is a 14 item list with each item consisting of a five-point ordinal scale ranging from 0 to 4during a series of predetermined tasks. The total score ranges from 0 - 56. |
| Changes in performance of dynamic balance after 8 sessions intervention | The assessments will be conducted before and after intervention (4 Weeks, 8 Sessions) | By using Timed Up and Go Test (TUG) to assess fall risk and measure the progress of balance. An older adult who takes ≥12 seconds to complete the TUG is at risk for falling. |
