The Impact

Introduction: Rheumatoid arthritis (RA) is a chronic disease that leads to disability of patients. The use of the whole-body cryotherapy treatment for RA patients provides analgesic and anti-inflammatory effects and improves their efficiency. Aim: Assessment of the effect of the whole-body cryotherapy treatment on the functional state of knee joints for patients with RA. Material and Method: The study was conducted on a group of 30 RA patients, who underwent a series of 10 whole-body cryotherapy treatment. The effectiveness and efficiency of the applied therapy was assessed on the basis of: the VAS scale, the Laitinen scale, the assessment of the range of motion, muscle strength with the MicroFet dynamometer and the Up and Go test. Results: As a result of the applied whole-body cryotherapy treatment, a reduction in the intensity of pain, measured with the VAS scale and the Laitinen scale, and a reduction in the duration of morning stiffness by about 55% were found. There was an increase in the range of motion and muscle strength. The time needed to perform the Up and Go test was reduced by 17%. Conclusions: The whole-body cryotherapy treatment is an effective analgesic method of physiotherapy for patients with RA. It provides an improvement in the functional state, increases the range of motion, muscle strength and improves the gait function.

The relationship of muscle strength symmetry with the symmetry of dynamic activities such as vertical jump (CMJ) and with symmetry of ranges of motion is ambiguous. Therefore, the aim of the current investigation was to assess the relationship between the flexor/extensor strength ratio and the range of motion of the knee joints and VGRF during jump in a sample of young healthy men. The sample consisted of 64 healthy, active men. The flexor and extensor torques and ranges of active and passive mobility of both knee joints were measured. Vertical ground reaction force (VGRF) was measured using two platforms. There were no significant correlations between the symmetry of muscle strength and the symmetry of ranges of motion and the symmetry of the VGRF. Therefore, using the cluster analysis, 4 subgroups were distinguished due to the size of the flexor/extensor ratio (H/Q ratio). Significant differences were found in the level of strength of the knee flexors between the clusters. Detailed analysis of muscle strength symmetry and VGRF symmetry seem to confirm the Leading Joint Hypothesis theory of motion control in multi-joint systems. It was found that the process of controlling movement by the nervous system compensates for the small asymmetries in the level of muscle strength in the knee flexors and extensors, as well as small asymmetries of VGRF.

Objective It is important to evaluate the effect of age on muscular athletic capability in knee joints over healthy woman aged 45 to 64. The research could provide female ageing effect on muscular athletic capability for elderly persons, aiming to promote the relative research on exercise improvement and Women's health. Methods A total of 126 volunteers were selected. The knee muscle strength indexes were tested on side-to-side using self-developed digital isometric muscle function test system. Main indexes include muscle strength, muscle explosive force and muscle endurance on side-to-side. The age groups are classified with 5 years intervals recommended by WHO. The statistics of trend, correlation network, ANOVA and PCA were employed to distinguish the aging effects. All test were implemented in R platform (version 3.3.3). Results (1) muscle strength showed obvious differences between left and right; the relative higher explosive force occurred with extensor muscles on the left showing the significant changing point at 100 ms after 50; the muscle endurance and fatigue index showed side differences after 60. (2) muscle strength trend showed “down then up” characteristics with the slightly ahead of 55 on the right side as well as muscle endurance indexes. (3) indexes between explosive force variables showed strong significant difference (p<0.001) while muscle fatigue indexes showed side differences; muscle strength in flexor muscles displayed significant correlations with explosive force variables on the right but opposite in extensor muscles on the left. (4) the huge difference occurred in extensor groups especially the comparison between minimum and maximum groups. (5) the main influences on knee muscular athletic capability include explosive force variables as well as muscle fatigue index. Conclusions Both ageing effect and side effect are observed in muscular athletic capability in knee joints over healthy woman aged 45 - 64 years. After 55, the related variables showed decrease trend indicating the potential decreased muscular athletic capability. In both flexor and extensor muscles, strength variables displayed significant side differences, showing high explosive force in flexor muscles on the right side. The crucial age 50 and 55 became the  turning points for knee muscular athletic capability especially with explosive forces.

Seventeen patients with rupture of the posterior cruciate ligament (PCL), 7 untreated and 10 having reconstruction of the PCL using the medial head of the gastrocnemius and the attached adductor tendon, were recruited for functional evaluation. The clinical functional status of the knee joint was evaluated in accordance with Hughston's criteria and Lysholm's score. The patients' gaits were analyzed using a three-dimensional electrogoniometer and mats. Muscle strength was assessed via Cybex-340; and a KT-1000 arthrometer was used to measure the laxity of the knee joints. Muscle strength tests showed a significant difference ( p < 0.01) in the knee extensors when the injured side was compared with the noninjured side in the untreated group, while no significant difference existed in reconstructed group. The gait analysis revealed that a significant difference existed over the velocity ( p < 0.05) when the reconstructed group was compared with the untreated group. The KT-1000 arthrometer test demonstrated that the anterior and posterior drawer at a knee flexion of 70 degrees and the posterior tibial sag screen at 90 degrees, differed significantly ( p < 0.01) between injured and noninjured limbs in the untreated group. In the reconstructed group only the anterior drawer presented a significant difference ( p < 0.05) between the injured and noninjured limbs. Using Hughston's and Lysholm's criteria, reconstruction was shown to have improved the knees' functions and scores postoperatively ( p < 0.01). The authors concluded that although the overall clinical results along with dynamic function, stability and strength of the extensor of the knee joints with PCL deficiency, were significantly improved after reconstruction using the medial head of the gastrocnemius together with the adductor tendon, yet, the normal perfect knee functions were still not achieved. A more sophisticated reconstructive procedure needs further investigation.
