“…Following a 10-week strengthening program, the PTTD group exhibited a 58% increase in strength, concomitant with significant reductions in pain. Houck et al 8 also reported that patients with PTTD exhibited 30% reduced ankle invertor strength compared to age-matched controls. However, while these 2 studies indicate that ankle invertor strength may be associated with PTTD, the individuals with PTTD in the aforementioned studies were at stages II to IV of the condition, and no study has investigated individuals with stage I PTTD for potential differences in ankle invertor strength.…”

“…However, these authors did not measure AHI, so comparisons are difficult. Both Neville et al 24 and Houck et al [8][9][10] measured AHI in individuals with stage II PTTD and found significantly lower values than in healthy controls. Therefore, the results of the current study suggest that arch structure, while perhaps not a contributing factor in stage I PTTD, may be more apparent in later stages of the condition.…”

Posterior tibial tendon dysfunction (PTTD) is a progressive and debilitating condition that is estimated to affect nearly 5 million people in the United States. 7 In the early stages (stage I) of the condition, PTTD is a common running-related injury. 31While the aetiology of PTTD has not been established, it is considered multifactorial in nature and has generally been related to progressive alterations in arch structure, muscular strength, and gait biomechanics. T T BACKGROUND:PTTD is a progressive condition, so early recognition and treatment are essential to help delay or reverse the progression. However, no previous studies have investigated stage I PTTD, and no single study has measured static anatomical structure, muscle strength, and gait mechanics in this population. T T METHODS: Twelve individuals with stage I PTTDand 12 healthy, age-and gender-matched control subjects, who were engaged in running-related activities, participated in this study. Measurements of arch height index, maximum voluntary ankle invertor muscle strength, and 3-dimensional rearfoot and medial longitudinal arch kinematics during walking were obtained. T T RESULTS:The runners with PTTD demonstrated significantly lower seated arch height index (P = .02) and greater (P = .03) and prolonged (P = .05) peak rearfoot eversion angle during gait, compared to the healthy runners. No differences were found in standing arch height index values (P = .28), arch rigidity index (P = .06), ankle invertor strength (P = .49), or peak medial longitudinal arch values (P = .49) between groups. T T CONCLUSION:The increased foot pronation is hypothesized to place greater strain on the posterior tibialis muscle, which may partially explain the progressive nature of this condition.

“…To date, foot and ankle kinematics in persons with stage 2 AAFD have only been evaluated during the bilateral heel-rise test. 11 A previous study by Houck and colleagues 11 found that individuals with unilateral AAFD achieved similar bilateral heel-rise height, as well as similar forefoot (first metatarsal relative to calcaneus) and rearfoot (calcaneus relative to tibia) PF excursions, to that of healthy controls. However, the heel-rise height in persons with AAFD was achieved with the forefoot in significant pronation.…”

“…2 Prolonged pronation likely overloads the posterior tibialis tendon, resulting in localized degenerative changes, impaired muscle strength capacity, and pain. In the presence of flatfoot deformity, the result is typically increased hindfoot eversion, 16,17 increased transverse plane foot motion, 28,29,38 inefficient propulsion during locomotion, 32 and diminished plantar flexion moment. 28,32 The actions of the hip extensors and abductors are essential during walking.…”

“…The single-leg heel raise task is considered a clinical test of plantar flexor strength 22,27 and posterior tibialis muscle function. 17 Bilateral hip extensor and hip abductor isometric strength and endurance were assessed using the PrimusRS dynamometer (BTE Technologies, Hanover, MD). In healthy participants, the testretest reliability assessed by ICC for hip strength was 0.87 (extension) and 0.80 (abduction), and for hip endurance was 0.88 (extension) and 0.27 (abduction).…”

Persons with acquired flatfoot deformity demonstrate impaired walking performance, as indicated by slower walking speed and frequent reports of foot pain during activity and at rest. 25,29 There is no doubt that acquired flatfoot deformity is accompanied by some level of tibialis posterior tendon dysfunction. The tibialis posterior functions to create a rigid foot segment by stabilizing the midfoot 37 and assists in generating energy, by the plantar flexors in terminal stance, to produce successful propulsion. 41 Laboratory studies confirm that persons with acquired flatfoot deformity demonstrate T T STUDY DESIGN: Controlled laboratory study using a cross-sectional design. T T OBJECTIVES:To characterize ankle and hip muscle performance in women with posterior tibial tendon dysfunction (PTTD) and compare them to matched controls. We hypothesized that ankle plantar flexor strength, and hip extensor and abductor strength and endurance, would be diminished in women with PTTD and this impairment would be on the side of dysfunction. T T BACKGROUND:Individuals with PTTD demonstrate impaired walking abilities. Walking gait is strongly dependent on the performance of calf and hip musculature. T T METHODS:Thirty-four middle-aged women (17 with PTTD) participated. Ankle plantar flexor strength was assessed with the single-leg heel raise test. Hip muscle performance, including strength and endurance, were dynamometrically measured. Differences between groups and sides were assessed with a mixed-model analysis of variance. T T RESULTS:Females with PTTD performed significantly fewer single-leg heel raises and repeated sagittal and frontal plane non-weight-bearing leg lifts, and also had lower hip extensor and abductor torques than age-matched controls. There were no differences between sides for hip strength and endurance measures for either group, but differences between sides in ankle strength measures were noted in both groups. T T CONCLUSION:Women with PTTD demonstrated decreased ankle and hip muscle performance bilaterally.
