Subjects with neurological disease (ND) usually show impaired performance during sit-to-stand and stand-to-sit tasks, with a consequent reduction in their mobility levels.


To determine the measurement properties and feasibility previously investigated for clinical tests that evaluate sit-to-stand and stand-to-sit in subjects with ND.


A systematic literature review following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) protocol was performed. Systematic literature searches of databases (MEDLINE/SCIELO/LILACS/PEDro) were performed to identify relevant studies. In all studies, the following inclusion criteria were assessed: investigation of any measurement property or the feasibility of clinical tests that evaluate sit-to-stand and stand-to-sit tasks in subjects with ND published in any language through December 2012. The COSMIN checklist was used to evaluate the methodological quality of the included studies.


Eleven studies were included. The measurement properties/feasibility were most commonly investigated for the five-repetition sit-to-stand test, which showed good test-retest reliability (Intraclass Correlation Coefficient:ICC=0.94-0.99) for subjects with stroke, cerebral palsy and dementia. The ICC values were higher for this test than for the number of repetitions in the 30-s test. The five-repetition sit-to-stand test also showed good inter/intra-rater reliabilities (ICC=0.97-0.99) for stroke and inter-rater reliability (ICC=0.99) for subjects with Parkinson disease and incomplete spinal cord injury. For this test, the criterion-related validity for subjects with stroke, cerebral palsy and incomplete spinal cord injury was, in general, moderate (correlation=0.40-0.77), and the feasibility and safety were good for subjects with Alzheimer's disease.


: The five-repetition sit-to-stand test was used more often in subjects with ND, and most of the measurement properties were investigated and showed adequate results.

According to the World Health Organization1, neurological diseases (NDs) are conditions that affect the central or peripheral nervous system of humans. With the decrease in mortality rates, there are increasingly more individuals affected by ND who have major disabilities, such as limitations in daily activities2. Standing and sitting on a chair are among the most affected activities and are considered crucial for independence in the daily routine3. The inability to perform these actions may lead to disability4. Therefore, recovering or improving the performance of these activities is a major goal for rehabilitation teams4. To do so, practitioners need clinical tools that assess these activities5 with adequate measurement properties (such as validity and reliability)4 , 6.

In 1985, Czuka and McCarty7 proposed and documented the first standardized test to clinically assess the sit-to-stand movement, originally called timed-stands test. This test determined the time spent to perform 10 repetitions of the sit-to-stand movement7. Subsequent variations were developed, including the "20-second sit-to-stand test" (sit-to-stand test)8 and the "five-repetition sit-to-stand test" (five times sit-to-stand test)9. The latter has demonstrated good clinical feasibility in the elderly10 and good test-retest reliability in healthy individuals between 14 and 85 years of age11.

Considering that measurement and feasibility properties depend on the protocol used and are specific to the population studied12, the adequate results shown for some properties of the test in certain populations do not guarantee that these tests will be similarly suitable for individuals with ND. Thus, the present study aimed to determine the measurement or feasibility properties previously investigated in clinical trials that evaluated the sit-to-stand/stand-to-sit movement in individuals with ND.


The present study is a systematic literature review conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) protocol13 , 14. All stages were performed by two independent raters who, at the end of each stage, reached a consensus on the results obtained. A third rater was involved in case of disagreement between the first two raters13 , 14.

In the first stage, electronic searches were performed on the MEDLINE, SCIELO, LILACS and PEDro databases to identify studies, using a search strategy adequate for databases with combinations of terms relative to the tests of interest and measurement or feasibility properties (Appendix 1). Subsequently, the studies were assessed for the inclusion criteria: studies that investigated any measurement property or the feasibility of any clinical trial that assessed sit-to-stand and stand-to-sit tasks in individuals diagnosed with ND and studies that were published in any language through December 2012.

In the second stage, the titles of the studies were evaluated, and studies that clearly did not meet the inclusion criteria were excluded. The same procedure was used in the third stage, in which the abstracts of the studies included in the second stage were analyzed. In the fourth stage, all studies included in the third stage were fully read, and those that met the inclusion criteria were included. In the fifth stage, an active manual search was performed of all the references from the studies included in the electronic search, following the previously mentioned procedures13 , 14.

The sixth stage consisted of assessing the methodological quality of the studies using the Consensus-based standards for the selection of health Measurement Instruments (COSMIN)15 - 17, which features standardized criteria18 and allows the classification of the methodological quality of studies that investigate the measurement properties of an instrument15 - 18. COSMIN has been most commonly used to assess the methodological quality of questionnaire-based instruments and was developed for this purpose18 - 20. However, the tests investigated in the present study are performance-based. In the classification system proposed by Bloemendaal et al.19, the final score depends on the percentage of items scored in COSMIN, and this classification system had already been used in a systematic review of the measurement properties of other performance-based tests19. This classification system seemed adequate and was therefore used. Thus, the COSMIN criteria were used by two independent raters, who reached a consensus on the final classification of the methodological quality of the included studies, and a third rater was involved in case of disagreement19.


In total, 141 studies were found in the electronic search, 125 of which were excluded in the second stage of the analysis because they did not assess individuals with ND or were not related to clinical sit-to-stand and stand-to-sit tests. In the third stage, six studies were excluded because they did not refer to the population of interest or any test of interest or did not evaluate any property of the test used. In the fourth stage, all ten analyzed studies met the inclusion criteria and remained in the study. An active manual search was performed in these ten studies, which resulted in one more study being included, for a total of 11 studies (Figure 1). Considering the COSMIN classification system proposed by Bloemendaal et al.19, most of the studies included (96%)8 , 9 , 21 - 28 had a sufficient methodological quality, and one study (4%)29 had a good methodological quality (Table 1).

*: related to the same test: "five-repetition sit-to-stand test"

The populations of the included studies ranged from children to the elderly, and the "five-repetition sit-to-stand test" was used by most studies on the following individuals: those with stroke, ambulating independently (3/11)21 , 23 , 24; those with dementia, ambulating independently (1/11)27; those with multiple sclerosis (MS) but without disabilities or ambulating with bilateral weight bearing (1/11)29; those with incomplete spinal cord injury, ambulating with moderate dependence or independently (1/11)25; those with Parkinson's disease (PD) with minimal dysfunctions (1/11)9; those with Alzheimer's disease (AD), ambulating independently26 and those with cerebral palsy (CP) whose functional level was not described28 (Table 2). Individuals with Down Syndrome ambulating independently were also evaluated with the "20-second sit-to-stand test"8, and individuals with dementia, whose functional level was not described, were also evaluated with the "30-second sit-to-stand test"22 (Table 2).

Among the studies that investigated the "five-repetition sit-to-stand test", 77% used chairs with a fixed seat height9 , 21 , 23 , 24 , 26 , 27 , 29, and 11% used a seat height adjustable to the individual's leg length8 , 28 (Table 3). Most of the studies (77%) reported that there were no arm rests on the chair8 , 9 , 23 - 25 , 28 , 29, and 66% used chairs with backrests9 , 23 - 25 , 27. No study that used this test allowed the use of the upper limbs9 , 21 , 23 - 25 , 27 , 29, and in 90% of the studies, the upper limbs of the individual were crossed23 , 26 , 27 over the chest9 , 21 , 28 or over the torso24 , 29. Approximately 33% of the studies gave the patients a test demonstration23 , 24 , 28, 55.5% reported the number of repetitions performed in the test23 - 25 , 28 , 29, and 88.8% reported the instructions provided21 , 23 - 29 (Table 2).

Studies evaluating individuals with stroke21 , 23 , 24 included participants in the chronic phase, from both genders, with a mean age between 53.4 and 60 years (Table 2). These studies investigated some properties of the "five-repetition sit-to-stand test", such as reliability (test-retest23 , 24, inter-rater23 and intra-rater23), criterion validity (sensitivity and specificity21) and concurrent criterion validity23, all with adequate results (Table 4). For this same test used in individuals with MS (Table 2), the concurrent criterion validity was investigated, and moderate to good correlations were obtained between lower limb strength and body sway with eyes open (Table 4).

For the "five-repetition sit-to-stand test", the concurrent criterion validity was investigated with functional independence measures in individuals with incomplete spinal cord injury, using a point biserial correlation coefficient and obtaining a negative value of 0.59525 (Tables 2 and 4). In children with CP (Table 2), the convergent criterion validity was investigated, and Pearson's Correlation Coefficient values of 0.4 to 0.7828 were obtained (Table 4). For the population with dementia (Table 2), the test-retest reliability was assessed, and an intraclass correlation coefficient (ICC) value of 0.9427 (Table 4) was obtained. For individuals with AD (Table 2), the test was considered safe and with good clinical feasibility26 (Table 4).

The only study that used the "20-second sit-to-stand test" provided instructions regarding the pace of the test and allowed the participants to use their upper limbs (Table 3). Moreover, this study assessed the test-retest reliability in 21 individuals with Down Syndrome between five and 31 years from both genders who were ambulating independently (Table 2). Significant and at least moderate CCI values (0.54 to 0.76) (Table 4)8 were obtained. The only study that used the "30-second sit-to-stand test" used a chair with adjustable seat height, performed three repetitions of the test (Table 3) and assessed the test-retest reliability and measurement error in 52 subjects with mild to moderate dementia (Table 2). To investigate the measurement properties, intra-class correlation coefficients (ICC), standard measurement error and minimal detectable change were used, and values of 0.84, 1.26 and 3.49, respectively, were obtained (Table 4)22.


The present study aimed to determine the measurement or feasibility properties of clinical trials that evaluated the sit-to-stand and stand-to-sit movements in individuals with ND. When assessing the methodological quality, many of the included studies obtained sufficient results by the classification system proposed by Bloemendaal et al.19. The lower scores were due to a small sample size and a lack of a description of the conditions of the individuals who performed the repeated measures, while the highest scores were related to the use of adequate statistical tests to assess the measurement properties.

Generally, the most commonly used test was the "five-repetition sit-to-stand test", and the most investigated property was the test-retest reliability. Other reliability measures were investigated, such as measurement error and criterion validity (convergent, concurrent, sensitivity/specificity), safety and clinical feasibility, most of which yielded adequate results. This test was performed in children, adults and the elderly, and individuals with stroke were those most commonly evaluated. The test-retest reliability and the measurement error of the "30-second sit-to-stand test" were also investigated in individuals with dementia, and the test-retest reliability of the "20-second sit-to-stand test" was assessed in individuals with Down syndrome, generally with adequate results. Other populations of individuals with ND and other properties were not investigated.

When comparing the results of several studies that evaluated the same property of the same test in populations with different NDs, the present review showed that the "five-repetition sit-to-stand test" showed a higher test-retest reliability in individuals with stroke23 , 24, dementia26 and CP28, although this property was also good for the other populations studied, PD9 and AD26. Regarding the inter-rater reliability of this same test, the results were adequate12 and similar in individuals with stroke23, incomplete spinal cord injury25 and PD9. In the population with stroke, this same test also showed adequate values12 of intra-rater reliability, similar to those obtained for inter-rater reliability23.

Some studies added informative value to the test-retest reliability measures by also assessing the measurement error by calculating the standard error of the mean and the minimum detectable change, which reflects the variability of the data in the sample12. However, this property was analyzed for more than one population group only for the "five-repetition sit-to-stand test", and the results indicated a lower variability in the measurements of this test in individuals with CP28, followed by individuals with AD26. For individuals with stroke24, the variability was considerably higher. Therefore, the possibility of this test providing more stable measurements with fewer errors is higher12 in individuals with CP. In individuals with stroke, the changes observed between assessments performed at different times (such as pre- and post-intervention) should not be related to the measurement error that may occur when using this test12.

The concurrent criterion validity of the "five-repetition sit-to-stand test" was assessed in individuals with stroke23, multiple sclerosis29, incomplete spinal cord injury25 and CP28. For individuals with stroke, significant correlations were obtained with isometric strength of the extensor muscles of both knees23, which were negative and with good magnitude12. For individuals with multiple sclerosis, the correlations found were significant, negative and moderate12 for lower limb strength and body sway with eyes open29. For individuals with incomplete spinal cord injury, significant, negative and moderate correlations12 with the Functional Independence Measure scores25 were reported. Finally, for children with CP, significant correlations were reported, which were positive and good12, for isometric muscle strength of hip flexors and abductors28. Therefore, this test showed better validity for the isometric strength of knee extensor muscles in individuals with stroke and hip flexors and abductors in individuals with CP.

Other measurement and feasibility properties were not studied for the same test in different populations, so comparisons similar to those previously performed could not be made. Conversely, a given property was investigated for different tests applied to the same population group. Two studies investigated the test-retest reliability for individuals with dementia, one investigated the "five-repetition sit-to-stand test"27 and one investigated the "30-second sit-to-stand test"22. In this comparison, the "five-repetition sit-to-stand test" showed higher ICC values when compared to the "30-second sit-to-stand test"12; thus, the former test seems to be the most adequate for individuals with dementia.

The "five-repetition sit-to-stand test" was the only test that showed any of the feasibility properties investigated, which were safety and clinical feasibility in individuals with AD. The results were similar to those reported by studies that investigated these measurement properties for this test in individuals without ND7 , 10. The test proved to be fast, was easy to perform, demanded little physical space and did not require special equipment. Further studies that clarify the feasibility of tests that assess the sit-to-stand movement in individuals with conditions other than NDs are still necessary.

Unlike already well-established clinical trials30, the protocols of the tests used to evaluate the sit-to-stand movement are still not completely standardized or clearly described by the studies. This limitation hinders the interpretation of the results and the reproduction of the tests in a clinical environment, given that parameters such as instructions, for example, may influence the results of performance-based tests31. In addition, in a literature review, Janssen et al.32 identified 19 determinants of the sit-to-stand movement, which have been clearly established and grouped into three categories related to the chair (such as seat height and the presence of arm and torso support), the individual (such as age, underlying disease and the use of shoes) and the strategy (such as speed and the positioning of the feet and upper limbs). These determinants influence the movement performed and may therefore influence the test results. Thus, ideally the sit-to-stand movement should be standardized, taking into consideration these determinants, including the characteristics of the individual32, so that the standardization would not compromise the clinical feasibility of the tests.

One of the determining factors for the sit-to-stand movement is the speed with which these activities are performed: when fast, the muscular demand imposed on the lower limbs of the individual is high32. Most likely, to require the maximum biomechanical performance, the test speed used in most studies was as high as possible21 - 29. Another determining factor for the sit-to-stand movement is the size of the chair and its other characteristics. The height of the chair has already been shown to interfere with the performance of the sit-to-stand movement32. One strategy already proposed for standardization is adjusting the chair height to the leg length of the individual, which was adopted only by two studies8 , 28. In most of the studies, the seat height was fixed9 , 21 , 23 , 24 , 26 , 27 , 29, and the results reflected the grouping of biomechanically favored and disadvantaged individuals according to the relationship between leg length and seat height.

Another determining factor for the sit-to-stand movement is the use of the upper limbs, which decreases the biomechanical demand for the individual, such as the muscular demand of the lower limbs32. Possibly for this reason, most studies did not allow the use of the upper limbs during the tests9 , 21 , 23 - 29. Conversely, not using the upper limbs during the test can hinder or prevent its application in individuals with greater motor impairment33, who are often a large portion of the population affected by ND34. These reasons may explain why a clear standardization regarding the positioning of the upper limbs was not observed among these studies, which on the one hand, increased the number of individuals able to perform the tests but on the other hand, created difficulty in comparing the results. Moreover, studies comparing the results of the different tests that assessed the sit-to-stand movement and considered the use of the upper limbs and their positioning were not found. We suggest the establishment of criteria or categories for the analysis that consider the functionality level of the individual when determining the best standardization for the upper limbs in these tests. This guideline would allow a greater proportion of individuals with ND to be included, as they are already included in studies that used the "five-repetition sit-to-stand test" in the elderly35.

The positioning of the feet (symmetrical, asymmetrical, both in front of and behind the knees) may also modify the biomechanical demand and the strategy for performing the sit-to-stand movement32 , 36 , 37. Only two studies described this feature: the feet were positioned 10 cm behind the knees in individuals with incomplete spinal cord injury25 and parallel to each other in individuals with multiple sclerosis29. In the first case, the muscular demand of the lower limbs is lower, and therefore, the time spent on the test may be shorter. The parallel positioning may facilitate or hinder the test performance, depending on the population group. According to a study conducted on individuals with stroke36, the parallel positioning requires symmetry in the biomechanical demand of the lower limbs, which, in this population, could hinder the test performance. However, it is uncertain whether the same effect would apply to individuals with other NDs. Both studies that described the feet positioning used during the test investigated the criterion validity but for distinct constructs, which does not allow comparisons between them.

Final remarks

The clinical evaluation of the sit-to-stand movement in individuals with ND has been performed using three different tests. The "five-repetition sit-to-stand test" is the most widely used and investigated test, and it shows the best reliability in individuals with stroke, dementia and CP, as well as the best criterion validity in individuals with stroke and CP. This test was also considered the most adequate for individuals with dementia when compared to the "30-second sit-to-stand test" because it showed the best test-retest reliability values. The feasibility properties were investigated only for the "five-repetition sit-to-stand test" in individuals with AD, and good results were obtained. There are still not enough data on the main determining factors of the sit-to-stand movement to allow the adequate standardization of the test protocols, which hinders the investigation of measurement properties and intra- and inter-group comparisons. Furthermore, although adequate results were already found for measurement and feasibility properties when evaluating these clinical trials, properties that may better reflect the clinical usefulness of these tests have not yet been investigated, such as responsiveness, or were not thoroughly discussed, such as safety, clinical feasibility and inter- and intra-rater reliability in different NDs.
