ACUTE EFFECTS OF SLING EXERCISE RECOVERY WITH WHOLE-BODY VIBRATION RESTING MUSCLE FUNCTION AND BLOOD OF LACTATE

The purpose of this study was to investigate an effective recovery method on muscle function and blood of lactate level after maximal isotonic exercise. This study was conducted in 36 adult males. The group was divided into three groups. Sling therapy group (SG, [Formula: see text]), sling therapy group with whole body vibration continuous (SAVG, [Formula: see text]) and sling therapy group with whole body vibration in intermittent (SIVG, [Formula: see text]) were randomly composed. Sling exercise therapy using supine position and whole-body vibration of 10[Formula: see text]Hz, 5[Formula: see text]mm were performed. Lactate level and muscle function during the rest, fatigue and recovery period were measured and then maximal exercise using back extension was performed to induce fatigue. After 15[Formula: see text]min, sling with whole body vibration was conducted in two groups, respectively. Blood lactate was measured a few hours before and after of vibration. Also, muscle function between only sling exercise therapy condition, sling with whole body vibration condition in all time and sling with whole body vibration condition in intermittent time were analyzed. Lactate level was recorded by lactate measurement device. Isokinetic of lumber joint extension and flexion Peak torque/body weight, total work (J), average power (W) and acceleration time (m/s2) were measured using isokinetic dynamometer. The recovery method of sling with whole body vibration showed positive changes in physical characteristics. Isokinetic contraction of peak torque/body weight (N[Formula: see text]m), average power (Watts) and total work (J) were significantly increased in the recovery step for SIVG. Lactate level was significantly decreased for SIVG as compared with SG and SAVG. This study demonstrated that sling exercise therapy with intermittent time whole body vibration could provide a positive effect on the efficient recovery of muscle function and higher reduction of lactate after maximal isotonic exercise.

Clinical research on lumbar oblique-pulling manipulation in combination with sling exercise therapy for patients with chronic nonspecific low back pain

SUMMARY OBJECTIVE: To investigate clinical curative effects of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training on chronic nonspecific lower back pain. METHODS: A total of 60 patients with chronic nonspecific lower back pain in the Outpatient Department were included in this study. These patients were randomly divided into two groups: the observation group and the control group. The control group adopted a single sling-exercise-therapy training three times a week, while the observation group adopted lumbar oblique-pulling manipulation in combination with manipulation treatment once a week. The course of treatment lasted for four weeks. RESULTS: (1) Before and after treatment, the ODI score was compared within the group. A remarkable statistical significance was observed from the third day (P<0.05). At the third month of follow-up, the difference in ODI scores between these two groups was statistically significant (P<0.05). (2) Before and after treatment, it was observed that differences in VAS scores from the third day were statistically significant (P<0.05). (3) The difference in muscle strength between these two groups had remarkable statistical significance in the third month of follow-up (P<0.05). CONCLUSION: The effective rehabilitation function of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training in patients with CNLBP is superior to that of sling-exercise-therapy training alone.
