The role of measured resistance exercises in adolescent scoliosis.

Twenty adolescent patients (18 girls and 2 boys) with scoliosis ranging from 15 degrees-41 degrees in their major curve were treated with a progressive resistive training program for torso rotation. All patients demonstrated an asymmetry of rotation strength measured on specialized equipment, and surface electrode electromyograms showed inhibition of lumbar paraspinal muscles. Sixteen of 20 patients demonstrated curve reduction, and no patient showed an increase in curve.

Back extension endurance and strength: the effect of variable-angle roman chair exercise training.

STUDY DESIGN: A pre- and postintervention randomized, controlled trial was conducted. OBJECTIVE: To evaluate the effect of progressive resistance exercise training using a variable-angle Roman chair on the development of lumbar extensor endurance and strength. SUMMARY OF BACKGROUND DATA: Progressive resistance exercise for the lumbar extensors has been used successfully for low back pain rehabilitation, but the limitations of currently available back exercise devices have negatively affected its use. METHODS: For this study, 36 healthy volunteers were randomized into one of two groups: a variable-angle Roman chair exercise group (n = 18) that performed one set of 15 to 25 repetitions of dynamic progressive resistance back extension exercise on a variable-angle Roman chair three times per week for 8 weeks or a control group (n = 18) that did not perform resistance exercise. Before training and after 4 and 8 weeks of training, static back extension endurance (seconds) and isometric lumbar extension strength (Newton.meters) were recorded. RESULTS: The variable-angle Roman chair exercise group displayed a 42% increase in static back extension endurance at the 4-week and 8-week tests relative to the pretraining measure (P < 0.05). The control group did not increase back endurance time at either the 4-week or 8-week tests (P > 0.05). Neither the variable-angle Roman chair exercise group nor the control group displayed an increase in lumbar extension strength at the 4-week or 8-week tests (P > 0.05). CONCLUSIONS: Dynamic progressive resistance exercise training on a variable-angle Roman chair is capable of developing back extension endurance. Future research is needed to determine the clinical applicability of variable-angle Roman chair exercise training for patients with low back pain patients.

The contribution of aerobic fitness and back strength to lift capacity.

STUDY DESIGN: This study used a concurrent validation design with 45 healthy female participants. OBJECTIVE: To measure the relative contributions of aerobic capacity and back strength to lift capacity. SUMMARY OF BACKGROUND DATA: This was the first concurrent study of the relations among spine strength, aerobic capacity, and lift capacity. Previous research had demonstrated moderate to strong relations between spine strength and lift capacity and between aerobic capacity and lift capacity. METHODS: Multiple regression techniques were used on reliable and valid measures of each construct to study the individual and joint contributions of spine strength and aerobic capacity to lift capacity. RESULTS: Both spine strength and aerobic capacity make significant independent contributions to lift capacity, accounting for 11% and 27% of the variance, respectively. Taken together, the predictive power of these variables on lift capacity accounts for 43% of the variance. CONCLUSIONS: Lift capacity is dependent on both back strength and aerobic capacity. It may be inappropriate to use lift capacity as an indicator for the severity of spine impairment in a disability determination system without taking into account the individual's aerobic capacity. Treatment intended to improve the lift capacity of persons with spine impairment should anticipate that improvement in both back strength and aerobic capacity will improve lift capacity.

Electromyographic activity of the trunk extensor muscles: effect of varying hip position and lumbar posture during Roman chair exercise.

OBJECTIVE: To evaluate the effect of hip position and lumbar posture on the surface electromyographic activity of the trunk extensors during Roman chair exercise. DESIGN: Descriptive, repeated measures. SETTING: University-based musculoskeletal research laboratory. PARTICIPANTS: Twelve healthy volunteers (7 men, 5 women; age range, 18-35y) without a history of low back pain were recruited from a university setting. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Surface electromyographic activity was recorded from the lumbar extensor, gluteal, and hamstring musculature during dynamic Roman chair exercise. For each muscle group, electromyographic activity (mV/rep) was compared among exercises with internal hip rotation and external hip rotation and among exercises by using a typical lumbar posture (nonbiphasic) and a posture that accentuated lumbar lordosis (biphasic). RESULTS: For the lumbar extensors, electromyographic activity during exercise was 18% greater with internal hip rotation than external hip rotation (P< or =.05) and was 25% greater with a biphasic posture than with a nonbiphasic posture (P< or =.05). For the gluteals and hamstrings, there was no difference in electromyographic activity between internal and external hip rotation or between biphasic and nonbiphasic postures (P >.05). CONCLUSION: The level of recruitment of the lumbar extensors can be modified during Roman chair exercise by altering hip position and lumbar posture. Clinicians can use these data to develop progressive exercise protocols for the lumbar extensors with a variety of resistance levels without the need for complex equipment.

A prospective short-term study of chronic low back pain patients utilizing novel objective functional measurement.

The present study utilized recently developed diagnostic tests that permit recognition of functional deficits in spine mobility, trunk strength, endurance, coordination, and dynamic lifting capacity. Changes in these tests were compared to changes in psychological functioning (e.g., self-report of pain) as well as to outcome criteria such as return-to-work and resolution of litigation. The study utilized these tests repeatedly during a new treatment approach to feed back objective information of the patient's functional capacity, not amenable to simple visual inspection, to both the patient and the surgeon. The program itself integrated a low back physical rehabilitation program with a multimodal pain management program and was guided by repeated functional capacity measurements. A total of 66 patients were evaluated. Results demonstrated significant improvement in physical function in these patients, which was also accompanied by changes in self-report of pain complaints. Moreover, an 82% return-to-work rate was achieved in this sample which was initially 92% unemployed. These results indicate that the physician dealing with chronic low back dysfunction can employ objective measures of functional capacity as an alternative to the sole reliance on pain patient self-report or structured tests, such as radiographic imaging, which merely document a universal, progressive degenerative process.

A comprehensive treatment approach to chronic low back pain.

A comprehensive treatment program for chronic disability related to back disease has been presented. This program has used not only more traditional methods of medical care for the structural disabilities of chronic mechanical back disorders, but has used principles of active patient participation in the improvement process. The patients are educated in the manifestations of pain behavior in the phase II treatment program emphasis on pain sources is downgraded to allow positive reinforcement for healthy behavior to develop. By use of an organized team approach, a significant number of patients can be processed; and an overall reduction in use of alternative medical resources has occurred.
