BACKGROUND: Following amputation, patients with lower limb amputations (LLA) are classified into different functional mobility levels (K-levels) ranging from K0 (lowest) to K4 (highest). However, K-level classification is often based on subjective criteria. Objective measures that are able to differentiate between K-levels can help to enhance the objectivity of K-level classification. OBJECTIVE(S): The goal of this preliminary cross-sectional study was to investigate whether differences in hip muscle strength and balance parameters exist among patients with transfemoral amputations (TFA) assigned to different K-levels. METHODOLOGY: Twenty-two participants with unilateral TFA were recruited for this study, with four participants assigned to K1 or K2, six assigned to K3 and twelve assigned to K4. Maximum isometric hip strength of the residual limb was assessed in hip flexion, abduction, extension, and adduction using a custom-made diagnostic device. Static balance was investigated in the bipedal stance on a force plate in eyes open (EO) and eyes closed (EC) conditions. Kruskal-Wallis tests were used to evaluate differences between K-level groups. FINDINGS: Statistical analyses revealed no significant differences in the parameters between the three K-level groups (p>0.05). Descriptive analysis showed that all hip strength parameters differed among K-level groups showing an increase in maximum hip torque from K1/2-classified participants to those classified as K4. Group differences were also present in all balance parameters. Increased sway was observed in the K1/2 group compared to the K4 group, especially for the EC condition. CONCLUSION: Although not statistically significant, the magnitude of the differences indicates a distinction between K-level groups. These results suggest that residual limb strength and balance parameters may have the potential to be used as objective measures to assist K-level assignment for patients with TFA. This potential needs to be confirmed in future studies with a larger number of participants. Layman's Abstract Patients with lower limb amputation (LLA) are classified into different mobility levels, so-called K-levels, which are ranging from K0 (lowest) to K4 (highest). K-level classification is relevant for the patients as it determines the type of prosthetic components available. However, K-level can vary greatly based on the clinician or orthopedic technician individual assessment. Objective data from physical performance tests can help to improve K-level classification. Therefore, muscle strength tests of the amputation stump as well as balance tests were performed in this study to determine whether these parameters have the potential to support K-level classification. Twenty-two participants with a thigh amputation participated in the study (four K1/2-, six K3- and twelve K4-participants). Hip muscle strength on the amputation side was assessed as well as static balance in the double leg stance with eyes open and eyes closed. Analysis of the data showed that all hip strength parameters differed between the K-level groups, with maximum strength increasing from the K1/2 group to the K4 group. Group differences were also seen in the balance parameters with greater body sway for the K1/2 group when compared to the K4 group, especially when participants had their eyes closed. These results show that muscle strength tests of the residual limb and static balance tests may serve as additional measures to improve K-level assignment for patients with LLA. This was only an initial study and further studies with a larger number of participants are required to confirm these results.

Abstract Background Modifiable cardiovascular risk factors (MCRFs), such as those related to aerobic capacity, muscle strength, physical activity, and body composition, have been poorly studied in Takayasu arteritis (TAK). Therefore, the aim of the study was to investigate MCRFs and their relationships with disease status and comorbidities among patients with TAK. Methods A multicenter cross-sectional study was conducted between 2019 and 2020, in which 20 adult women with TAK were compared with 16 healthy controls matched by gender, age, and body mass index. The following parameters were analyzed: aerobic capacity by cardiopulmonary test; muscle function by timed-stands test, timed up-and-go test, and handgrip test; muscle strength by one-repetition maximum test and handgrip test; body composition by densitometry; physical activity and metabolic equivalent by IPAQ, quality of life by HAQ and SF-36; disease activity by ITAS2010 and NIH score; and presence of comorbidities. Results Patients with TAK had a mean age of 41.5 (38.0–46.3) years, disease duration of 16.0 (9.5–20.0) years, and a mean BMI of 27.7±4.5 kg/m2. Three out of the 20 patients with TAK had active disease. Regarding comorbidities, 16 patients had systemic arterial hypertension, 11 had dyslipidemia, and two had type 2 diabetes mellitus, while the control group had no comorbidities. TAK had a significant reduction in aerobic capacity (absolute and relative VO2 peak), muscle strength in the lower limbs, increased visceral adipose tissue, waist-to-hip ratio, reduced walking capacity, decreased weekly metabolic equivalent, and quality of life (P< 0.05) as compared to controls. However, there were no correlations between these MCRFs parameters and disease activity. Conclusions TAK show impairment in MCRFs; therefore, strategies able to improve MCRF should be considered in this disease.
