Effect of Age and Activity Level on Lower Extremity Gait Dynamics

Dancers frequently experience lower-extremity injuries which require dance activity restriction, if not full “time off” and/or surgery. Recovering dancers are frequently over-eager to return to dance, but engaging in too high an activity level too soon can be detrimental. Currently, there are no formal guidelines for general physicians about advising injured or postoperative dancer-patients about when or how to return to dance activity. Socioeconomic hurdles further prohibit many dancers from seeking rehabilitative services from a dance physical therapist. Therefore, there is a need for physician education about general dance-rehabilitation principles, as well as access to a dance-specific structured rehabilitation program. We present here rehabilitation advice from an expert in dance orthopedic surgery and an example of a “preventive rehabilitation program” for injured or postoperative dancer-patients with lower-extremity injury.

Context Patellofemoral pain (PFP) is a chronic condition that presents with lower extremity muscle weakness, decreased flexibility, subjective functional limitations, pain, and decreased physical activity. Patterned electrical neuromuscular stimulation (PENS) has been shown to affect muscle activation and pain after a single treatment, but its use has not been studied in a rehabilitation trial. Objective To determine the effects of a 4-week impairment-based rehabilitation program using PENS on subjective function, pain, strength, range of motion, and physical activity in individuals with PFP. Design Randomized controlled trial. Setting Laboratory. Patients or Other Participants A total of 21 patients with PFP (5 males, 16 females; age = 23.4 ± 7.6 years, height = 168.0 ± 7.5 cm, mass = 69.0 ± 19.5 kg). Intervention(s) Participants completed a 4-week supervised rehabilitation program in conjunction with random assignment to receive PENS or sham treatments. Main Outcome Measure(s) Subjective function, pain, strength, range of motion, and physical activity levels were assessed prerehabilitation and postrehabilitation. Subjective function and pain were also assessed at 6 and 12 months postrehabilitation. Repeated-measures analyses of variance and Tukey post hoc testing were conducted with α ≤ .05. We calculated Cohen d effect sizes with 95% confidence intervals. Results Both groups had statistically and clinically meaningful differences in subjective function, pain, strength, range of motion, and activity level after 4 weeks of impairment-based rehabilitation. Improved subjective function was observed in both groups at 6 and 12 months after the interventions. The PENS group had improvements in current pain for all 3 postrehabilitation times compared with baseline measures. Conclusions An impairment-based intervention effectively improved subjective function, pain, strength, range of motion, and physical activity levels in individuals with PFP. Participants who received PENS in addition to the rehabilitation program had improved current pain at 6 and 12 months postrehabilitation compared with baseline scores.

Anterior Knee

Effective management of patellofemoral pain is challenging to the practitioner when attempting to maintain the athlete's desired activity level while minimizing the symptoms. Due to the numerous etiological factors behind anterior knee pain, comprehensive management must include a lower extremity evaluation of muscular flexibility and strength as well as biomechanical abnormalities. Rehabilitation programs must focus on the flexibility, strength, endurance and proprioception of the extremity while reducing abnormal biomechanical forces. Programs to treat these abnormalities that increase patellofemoral stress must be systematically upgraded one variable at a time while monitoring the symptoms on a daily basis.
