Correlation of force sense error test measured by a pressure biofeedback unit and EMG activity of quadriceps femoris in healthy individuals.

BACKGROUND: Our study developed a force sense error test (FSET) method for use on the quadriceps muscle, which could be employed in clinical practice to correlate the results of quadriceps muscle activity levels determined by surface electromyography (sEMG). METHODS: Twenty-four healthy individuals were included in the study. A pressure biofeedback unit (PBU) placed under the knee joint, was used for force sense error test (FSET) evaluation. First, a maximum contraction value was determined with the PBU. Next, 50% and 65% of the maximum contraction value were used for the analysis. Concurrently, norm values for the quadriceps muscle activity levels were determined by sEMG. Simultaneously, quadriceps muscle activity levels were recorded while testing the FSET using the PBU. Each measurement was repeated in triplicate, and the average constant errors observed by the PBU were recorded in mmHg. RESULTS: The FSET for both 50% and 65% of the normal mmHg value determined using the PBU positively correlated with activity change levels in the quadriceps muscle determined by sEMG (p < 0.05). CONCLUSIONS: The relationship between the FSET measured using PBU and changes in the level of activity in the quadriceps muscle showed that a PBU can be used in clinical practice for proprioceptive evaluation of the knee region.

Multivariate Analysis of Risk Factors Predisposing to Kinesiophobia in Persons With Chronic Low Back and Neck Pain.

OBJECTIVE: The purpose of this study was to analyze the interaction between kinesiophobia and pain-related variables classified according to International Classification of Functioning in individuals with chronic neck and low back pain by using multivariate analysis. METHODS: The 504 persons with chronic neck and low back pain filled out questionnaires assessing impairments in body functions and structures, limitations in activities of daily living, participation, and personal factors. Univariate analyzes were performed to investigate whether there are differences between individuals with and without kinesiophobia or not. Binary logistic regression analysis was used to evaluate whether independent variables were statistically significant predictors. RESULTS: In the univariate analyses, the persons who had high-level kinesiophobia had a significantly lower level of education and had significantly higher scores for the Million Visual Analogue Scale, Neck Disability Index, Hospital Anxiety and Depression Scale, and Nottingham Health Profile (P < .001). In the final logistic regression analysis, only educational level (P = .01), Million Visual Analogue Scale (P = .002) and Hospital Anxiety and Depression Scale (P = .008, P = .012) were retained significantly as the predictors of kinesiophobia. CONCLUSION: In this group of people with chronic neck and low back pain, educational level, low back pain-associated disability, and emotional states like depression and anxiety were associated with kinesiophobia.

Gait and Glasgow Coma Scale scores can predict functional recovery in patients with traumatic brain injury.

Fifty-one patients with mild (n = 14), moderate (n = 10) and severe traumatic brain injury (n = 27) received early rehabilitation. Level of consciousness was evaluated using the Glasgow Coma Score. Functional level was determined using the Glasgow Outcome Score, whilst mobility was evaluated using the Mobility Scale for Acute Stroke. Activities of daily living were assessed using the Barthel Index. Following Bobath neurodevelopmental therapy, the level of consciousness was significantly improved in patients with moderate and severe traumatic brain injury, but was not greatly influenced in patients with mild traumatic brain injury. Mobility and functional level were significantly improved in patients with mild, moderate and severe traumatic brain injury. Gait recovery was more obvious in patients with mild traumatic brain injury than in patients with moderate and severe traumatic brain injury. Activities of daily living showed an improvement but this was insignificant except for patients with severe traumatic brain injury. Nevertheless, complete recovery was not acquired at discharge. Multiple regression analysis showed that gait and Glasgow Coma Scale scores can be considered predictors of functional outcomes following traumatic brain injury.
