Effect of isokinetic training on strength, functionality and proprioception in athletes with functional ankle instability.

The purpose of this study was to investigate the effects of isokinetic exercise on strength, joint position sense and functionality in recreational athletes with functional ankle instability (FAI). Strength, proprioception and balance of 24 recreational athletes with unilateral FAI were evaluated by using isokinetic muscle strength measurement, ankle joint position sense and one leg standing test. The functional ability was evaluated using five different tests. These were; single limb hopping course (SLHC), one legged and triple legged hop for distance (OLHD-TLHD), and six and cross six meter hop for time (SMHT-CSMHT). Isokinetic peak torque of the ankle invertor and evertor muscles were assessed eccentrically and concentrically at test speeds of 120 degrees /s. Isokinetic exercise protocol was carried out at an angular velocity of 120 degrees /s. The exercise session was repeated three times a week and lasted after 6 weeks. At baseline, concentric invertor strength was found to be significantly lower in the functionally unstable ankles compared to the opposite healthy ankles (p < 0.001). This difference was not present after executing the 6 weeks exercise sessions (p > 0.05). Ankle joint position sense in the injured ankles declined significantly from 2.35 +/- 1.16 to 1.33 +/- 0.62 degrees for 10 degrees of inversion angle (p < 0.001) and from 3.10 +/- 2.16 to 2.19 +/- 0.98 degrees for 20 degrees of inversion angle (p < 0.05) following the isokinetic exercise. One leg standing test score decreased significantly from 15.17 +/- 8.50 to 11.79 +/- 7.81 in the injured ankles (p < 0.001). Following the isokinetic exercise protocol, all of the worsened functional test scores in the injured ankles as compared to the opposite healthy ankles displayed a significant improvement (p < 0.01 for OLHD and CSMHT, p < 0.001 for SLHC, TLHD, and SMHT). These results substantiate the deficits of strength, proprioception, balance and functionality in recreational athletes with FAI. The isokinetic exercise program used in this study had a positive effect on these parameters.

Comparison of the efficacies of botulinum toxin A and Johnstone pressure splints against hip adductor spasticity among patients with cerebral palsy: a randomized trial.

OBJECTIVE: The goal was to compare the efficacies of botulinum toxin A (BTX) treatment and Johnstone pressure splint (JPS) treatment against hip adductor muscle spasticity among children with spastic diplegic cerebral palsy. METHODS: For each patient in the BTX group, a total of 300 IU of BTX was injected into adductor and medial hamstring muscle groups. In the JPS group, long leg JPS were administered for 30 minutes 3 days per week. Bobath neurodevelopmental exercises were administered to both groups 3 days per week during the study period. All cases were assessed by using gross motor function measurements, passive hip abduction goniometric measurements, modified Ashworth Scale scores, and measurements of the distance between the knees as indicator variables. RESULTS: We found that there was statistically significant improvement in all indicators for both groups. BTX treatment was found to be superior to JPS treatment in terms of the indicator variables of our study.

Clinical significance of congenital lumbosacral malformations in young male population with prolonged low back pain.

STUDY DESIGN: A prospective clinical investigation. OBJECTIVE: To determine the clinical significance of congenital lumbosacral malformations in young male patients with subacute or chronic low back pain and to investigate a possible worsening of the clinical picture with the concurrence of transitional vertebra (TV) or spina bifida occulta (SBO). SUMMARY OF BACKGROUND DATA: Although the causative roles of congenital malformations in low back pain and lumbar disc herniation have been investigated, there is no study that compares the incidence of congenital malformations in prolonged low back pain between radicular and nonradicular groups; nor is there a study that compares the pain intensity between the groups with and without congenital malformations. METHODS: Lumbosacral plain radiographs of 881 young male patients with low back pain lasting for >4 weeks were evaluated. For all patients, we recorded the clinical signs and their pain intensities based on a 10-cm visual analog scale (VAS). RESULTS: Congenital lumbosacral malformations were determined in 88 of 881 patients. Of these, 48 were TV, 38 were SBO, and 2 were a combined lesion of TV and SBO. The difference in positive clinical sign and VAS was statistically significant (P < 0.05) between the groups with and without congenital lumbosacral malformations. In contrast to SBO, there was a statistically significant difference of TV incidence between the sign positive and the sign negative groups (P < 0.05). The difference in VAS values was statistically significant for both TV and SBO (P < 0.001). CONCLUSIONS: The results of this study show that SBO and TV increase the severity of the clinical picture whether or not they have a causal relationship. Additionally, transitional vertebrae seem to increase nerve-root symptoms whereas spina bifida occulta does not.

Efficacy of isokinetic exercise on joint position sense and muscle strength in patellofemoral pain syndrome.

OBJECTIVE: The objective of this study was to demonstrate the impairment of knee joint position sense in individuals with patellofemoral pain syndrome and investigate the effects of isokinetic exercise on knee joint position sense and muscle strength. DESIGN: A total of 24 male patients complaining of anterior knee pain caused by overexertion and 24 male healthy individuals without symptoms were included for this investigation. Isokinetic exercise protocol was carried out at angular velocities of 60 degrees/sec and 180 degrees/sec. These sessions were repeated three times per week and lasted for 6 wks. At the beginning and after 6 wks of knee passive joint position sense, quadriceps and hamstring muscle strength and pain assessments were performed. RESULTS: After the isokinetic exercise, flexion peak torque (P < 0.05), extension peak torque (P < 0.01), flexion total work (P < 0.001), extension total work (P < 0.001), passive reproduction of knee joint position sense for 40 degrees of flexion (P < 0.05) and 50 degrees of extension (P < 0.01), and pain score (P < 0.001) improved significantly in the patellofemoral pain syndrome group. CONCLUSION: Isokinetic exercises have positive effects on passive position sense of knee joints, increasing the muscular strength and work capacity. These findings show that using the present isokinetic exercise in rehabilitation protocols of patients with patellofemoral pain syndrome not only improves the knee joint stabilization but also the proprioceptive acuity.
