AIM: To explore how plyometric-based hydro-kinesiotherapy (Plyo-HKT) would affect pain, muscle strength, postural stability, and functional performance in a convenience sample of children with hemophilic knee arthropathy (HKA).
METHODS: Forty-eight children with HKA (age: 8-16 years) were randomly allocated to the Plyo-HKT group ( = 24; underwent the Plyo-HKT for 45 min, twice/week over 12 wk in succession) or the comparison group ( = 24; performed the standard exercise rehabilitation at an equivalent frequency and duration). Pain, peak concentric torque of quadriceps and hamstring (produced at two angular velocities: 120 and 180 /sec), dynamic limits of postural stability (DLPS), and functional performance [Functional Independence Score in Hemophilia (FISH) and 6-Minute Walk Test (6-MWT)] were assessed pre- and post-intervention.
RESULTS: In contrast with the comparison group, the Plyo-HKT group achieved more favorable pre-to-post changes in pain ( = .028, = 0.10), peak torque of quadriceps [120°/sec ( = .007, = 0.15); 180°/sec ( = .011, = 0.13)] and hamstring [120°/sec ( = .024, = 0.11); 180°/sec ( = .036, = 0.09)], DLPS [forward ( = .007, = 0.15); backward ( = .013, = 0.12); affected side ( = .008, = 0.14); non-affected side ( = .002, = 0.20)], DLPS ( < .001, = 0.32), and functional performance [FISH ( < .001, = 0.26); 6-MWT ( = .002, = 0.19)].
CONCLUSION: Plyo-HKT is likely helpful for reducing pain, improving strength, enhancing postural stability, and boosting functional capabilities in children with HKA. Physical rehabilitation practitioners should, therefore, consider this intervention strategy.
