The aim of the study was to evaluate effectiveness of rehabilitation in patients before and after rACL, based on stabilographic indicators. Methods: The research group was comprised of 31 men aged 20–57 with anterior cruciate ligament injury, qualified for reconstruction surgery. A measurement of static stabilometric indicators and muscle strength was taken twice for each patient – before surgery and after 6 months. To assess stabilographic indicators the stabilographic platform was used and to asses muscle strength a dynamometer was used. In order to assess knee function the Lysholm scale and VAS scale were used. Results: The rehabilitation programme improved static stability of the knee in the frontal plane, which is manifested by a significant shortening of the SPML path length. Rehabilitation proceedings should focus on improving static stability of the knee joint in the sagittal plane, because the results obtained indicate only a slight shortening of the SPAP length. The results of the Lysholm and VAS scales point to a positive influence of the applied rehabilitation. Conclusion: Inclusion into rehabilitation diagnostic tools to assess stabilometric indicators enables for effective verification of rehabilitation proceedings focused on restoring body posture control before and after the rACL.

Purpose: The assessment of hip joint abductor muscle strength is most often carried out using a dynamometric test. However, both in clinical practice and literature, evaluation is performed by means of the single-leg half-squat or the amount of abduction movements performed in the hip joint. In this context, the question arises whether the results of individual tests are convergent. The aim of the study is to evaluate the relationship between strength of the hip abductor muscle measured by dynamometer, the single-leg-squat and the number of repetitions of the movements in time. Methods: A group of 35 students (20 women and 15 men) between 20 and 24 years old participated in the study. Each student was subjected to three tests assessing the condition of the hip and associated abductor muscles. Those included: assessment of hip joint abduction muscle strength in a dynamometric study, assessment of the number of abdomen movements performed lying on the side and standing, during a 30-second interval, and the single-leg-squat test. Results: Based on the tests conducted, a significant relationship was observed between the muscle strength measurement results for the left and right side in the dynamometric study and the number of hip abduction repetitions in 30 seconds and the single-leg-squat test. Conclusions: The obtained results indicate a significant relationship between the results of all the tests. In practice, this means that the tests can be used interchangeably.

Purpose: Head constitutes 6% of our body weight and significantly influences human body motor system mechanics. From physiological point of view, it should be located at extension of body middle line. Its location being modified results in many consequences in motor system. Our research was aimed at assessing the influence of head position on human body balance stabilographic variables. Methods: The research was made on a group of 62 patients: 45 women and 17 men, aged from 40 to 60 yrs, 46 yrs on average. Head position in sagittal and frontal plane was assessed with photogrammetric method. Chosen stability parameters were estimated with dynamometric platform PEL 38 and computer software TWIN 99. Results: The results confirmed correlations between existing stabilographic values and head position in frontal plane only. Head position, when changed in this plane, increased the amplitude ( p = 0.001) and average speed of body gravity center trembilng ( p = 0.002). There were no significant relations found in sagittal plane ( p > 0.05). Conclusions: Our results show that the head position influences stabilographic variables. Its change in frontal plane decreases body posture stability to the largest extent.
