Comparison between efficacy of spinal mobilization with leg movement versus McKenzie technique in patients with lumbar disc herniation

Background: Lumbar disc herniation (LDH) is one of the most common causes of medical consultationin the orthopedic clinics. LDH is believed to be the root cause of 60-80 percent of low back pain cases over a lifetime. Objective: The current study aims to evaluate the effectiveness of different dissimilar manual therapy techniques (Mulligan’s spinal mobilization with leg movement versus McKenzie technique) in patients with lumbar disc herniation.Design: The present study is a randomized control trial in which 45 individuals diagnosed with LDH were recruited as the participants of the study (mean age 48.54 ± 5.8 years). The participants were randomly allocated into three groups, with n=15 in each group. Intervention:Participants of the group A (Experimental group A) received Mulligan spinal mobilization with leg movement and T.E.N.S. (Transcutaneous Electrical Nerve Stimulation). Group B (Experimental group B) participants received McKenzietechnique. Group C (control group) participants only received T.E.N.S. for four weeks. All patients in the three groups received 3 sessions each week. Pain, functional disability, and the H reflex were the primary outcome measures. The visual analogue scale (VAS) was used to assess pain, the Oswestry disability scale was used to assess functional disability, and electromyography was used to assess the H reflex.Results: Significant improvements were seen in the participants of group A, with reduction in the intensity and severity of pain, decreased level of functional disability and improvement in the H reflex, in comparison with other groups.Conclusion: Spinal mobilization with leg movement was more effective than McKenzietechniqueand TENS to reduce pain and functional disability, and to improve the H reflex, in individuals suffering from lumbar disc herniatio

Mechanical and Morphological Changes of the Plantar Flexor Musculotendinous Unit in Children with Unilateral Cerebral Palsy Following 12 Weeks of Plyometric Exercise: A Randomized Controlled Trial

To investigate how plyometric exercise (PLYO-Ex) affects mechanics and morphometrics of the plantar flexor musculotendinous unit in children with unilateral cerebral palsy, 38 participants (aged 10–16 years) were allocated at random to either the PLYO-Ex group (n = 19; received 24 sessions of plyometric muscle loading, conducted 2 times a week for 3 months in succession) or the control group (n = 19; underwent traditional physical therapy for the same frequency and duration). Measurements were taken pre- and post-intervention. Standard ultrasound imaging was applied to evaluate morphometrics of the gastrocnemius muscle and Achilles tendon unit and an isokinetic dynamometer was used to evaluate maximum voluntary isometric plantar flexors contraction (IVCmax). With controlling for pre-treatment values, significant post-treatment changes favoring the PLYO-Ex group were observed for morphological (tendon (p = 0.003, η2p = 0.23) length; belly length (p = 0.001, η2p = 0.27); tendon thickness (p = 0.035, η2p = 0.35); muscle thickness (p = 0.013, η2p = 0.17); fascicle length (p = 0.009, η2p = 0.18); pennation angle (p = 0.015, η2p = 0.16)) and mechanical and material properties (IVCmax (p = 0.009, η2p = 0.18); tendon’s elongation (p = 0.012, η2p = 0.17), stiffness (p = 0.027, η2p = 0.13); stress (p = 0.006, η2p = 0.20); strain (p = 0.004, η2p = 0.21)). In conclusion, plyometric exercise induces significant adaptations within the musculotendinous unit of the plantar flexors in children with unilateral cerebral palsy. These adaptations could improve muscular efficiency and consequently optimize physical/functional performance

Paretic-Limb-Only Plyometric Training Outperforms Volume-Matched Double-Limb Training for Ameliorating Balance Capability and Gait Symmetry in Adolescents with Unilateral Cerebral Palsy: A Comparative Study

Adolescents with unilateral cerebral palsy (U-CP) experience an asymmetrical posture because the less-affected lower limb is preferred for bodyweight support as a strategy of compensating for the paretic side’s muscular weakness. This study was designed to compare the effect of 12 weeks of paretic-limb-only plyometric training (PLPT) and volume-matched double-limb training (DLPT) on balance capability and gait symmetry in adolescents with U-CP. Sixty-nine adolescents with U-CP were randomly assigned to PLPT, DLPT, or a control group (n = 23 each). Treatment was delivered twice/week (with at least 48 h recovery intervals) for 12 weeks in succession. The directional (LoSdirectional) and overall (LoSoverall) limits of stability in addition to the temporal (T-GSI) and spatial (S-GSI) gait symmetry indicis were assessed pre- and post-treatment. The LoSdirectional improved significantly in the PLPT group compared to either the DLPT or control group (for the forward (p = 0.027 and <0.001, respectively), backward (p = 0.037 and <0.001, respectively), affected-side (p = 0.038 and 0.004, respectively), and less-affected-side (p = 0.018 and 0.016, respectively)), and this was also the case for the LoSoverall (p < 0.001). Additionally, The T-GSI and S-GSI scores decreased significantly in the PLPT group compared to the DLPT (p = 0.003 and 0.047, respectively) or control (p = 0.003 and 0.036, respectively) group, indicating the development more symmetrical gait patterns. In conclusion, PLPT is likely more effective for enhancing balance capabilities and promoting symmetrical gait patterns than DLPT. Thereupon, it is worthwhile for physical rehabilitation practitioners to include the PLPT paradigm into the intervention plans for adolescents with U-CP
