Introduction: Athletes and sports enthusiasts, who have sustained certain lower limb pathological conditions as well as have undergone certain surgical procedures, are commonly limited in their weight bearing ability. Accurate and reliable normative treadmill running must be identified in order for treating physicians to advise regarding the gradual return to weight-bearing activities.
Objectives: To identify the average percentage body weight (APBW) values and weight-bearing distribution patterns (WBDP) during treadmill jogging in a referent adult population.
Design & Methods: A gait analysis system (SmartStep™) was utilized to measure the above parameters. 40 asymptomatic individuals (median age, 34y; range, 19-72 y) participated in the study. Each subject ran for a 15 second time period on a treadmill (Technogym™ “run excite 700”), at a constant speed set of 8.5 km/hr.
Results: On the entire foot, the APBW value was 136.46% (SD=16.49), the hind foot, 34.30% (SD=15.52) and 110.85% (SD = 20.61) for the fore foot. The average time spent in the swing phase was 36.47% (SD= 2.61) and 63.53% (SD=2.61) in the stance phase. The group average cadence value was 109.54 steps/min (SD=19.86).
Conclusions: These results may now form the basis of rehabilitation protocols, which aim to return athletes to treadmill jogging within their weight-bearing limitations following certain lower limb orthopedic conditions as well as in sports injury rehabilitation.
Clinical relevance: To provide medical personnel with normative data in order to assist with decision making concerning weight-bearing abilities following certain lower limb pathological conditions and following certain surgical procedures.
