ABSTRACT
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.
ABSTRACT
BACKGROUND: Patients with chronic low back pain (LBP) have an impaired dynamic spinal stability, which may lead to arm injuries. OBJECTIVES: To examine the latissimus dorsi and gluteus maximus muscles activation pattern and the upward scapular rotation in patients with chronic LBP. METHODS: Sixty-one right-handed males were divided into two groups: chronic LBP group (n= 31) and healthy controls (n= 30). The electromyography (EMG) activities of the right and left latissimus dorsi and gluteus maximus were recorded. The upward scapular rotation in different shoulder positions (neutral, 45∘, 90∘, 135∘ abduction and end range) was measured in both groups. RESULTS: The LBP group has a bilateral significant increased EMG of latissimus dorsi (p< 0.05) and significantly decreased EMG of gluteus maximus (p< 0.05) compared to the control group, without significant differences between the right and left sides (p> 0.05). There was a significant increase in upward scapular rotation in the LBP group relative to the control group in all shoulder abduction positions on both sides. The left side upward scapular rotation was more significant than the right (p< 0.05). CONCLUSION: Chronic LBP increased the latissimus dorsi muscle activities and decreased the gluteus maximus activities. It furthermore increased the upward scapular rotation in different shoulder abduction positions.

OBJECTIVE: This study evaluated whether the use of kinesio taping (KT) would enhance the effect of physical therapy in relieving pain, improving muscle endurance, and boosting functional capacity in adolescents with hemophilia who experience low back pain. METHODS: Forty-five adolescents with hemophilia (age; 10-13 years) assigned randomly into three treatment arms; KT applied paraspinal alongside a physical exercise program conducted three times/week for three successive months (KT group; n=15), placebo taping plus physical exercise (Placebo group; n=15), or physical exercise only (Control group; n=15). Lower back pain, back muscle endurance, and functional capacity assessed pre- and post-treatment. RESULTS: Lower back pain reduced significantly in the KT group as compared to the control group (P=.001), but not to the placebo group (P=.19). Back muscle endurance increased significantly in the KT group relative to either the placebo (P=.004) or the control group (P=.043). Additionally, functional capacity improved significantly in the KT group as compared to the control (P=.039) group but not to the placebo group (P=.58). CONCLUSION: KT is an effective adjunctive therapy to reduce lower back pain, improve back muscle endurance, and enhance functional capacity in adolescents with hemophilia.
