Two randomized, double-blind, placebo-controlled studies assessed the analgesic efficacy of valdecoxib in patients with moderate-to-severe pain after bunionectomy. Study 1 (N = 374) assessed the efficacy of two regimens of valdecoxib on the day after surgery (valdecoxib, 40 mg, with a 20-mg redose [n = 127]; valdecoxib, 40 mg, with a placebo redose [n = 122]; and placebo/placebo [n = 125]), and study 2 (N = 478) examined the efficacy of two different multiple-dose regimens on postoperative days 2 through 5 (valdecoxib, 20 mg, twice daily [n = 160]; valdecoxib, 20 mg, once daily [n = 159]; and placebo [n = 159]). Valdecoxib provided significant pain relief and reduced the use of opioid rescue medication. This efficacy was accompanied by improved global scores, decreased pain interference with function, and increased patient satisfaction. (J Am Podiatr Med Assoc 96(5): 393–407, 2006)
To our knowledge, hand dominance and side of foot disorders has not been described in the literature. We sought to evaluate whether hand dominance was associated with ipsilateral foot disorders in community-dwelling older men and women.
Data were from the Framingham Foot Study (N = 2,089, examined 2002–2008). Hand preference for writing was used to classify hand dominance. Foot disorders and side of disorders were based on validated foot examination findings. Generalized linear models with generalized estimating equations were used to estimate odds ratios and 95% confidence intervals, accounting for intraperson variability.
Left-handed people were less likely to have foot pain or any foot disorders ipsilateral but were more likely to have hallux valgus ipsilateral to the left hand. Among right-handed people, the following statistically significant increased odds of having an ipsilateral versus contralateral foot disorder were seen: 30% for Morton’s neuroma, 18% for hammer toes, 21% for lesser toe deformity, and a twofold increased odds of any foot disorder; there was a 17% decreased odds for Tailor’s bunion and an 11% decreased odds for pes cavus.
For the 2,089 study participants, certain forefoot disorders were shown to be ipsilateral and others were contralateral to the dominant hand. Future studies should examine whether the same biological mechanism that explains ipsilateral hand and foot preference may explain ipsilateral hand dominance and forefoot disorders.

In a previous pilot study of “cruisers” (nonindependent ambulation), “early walkers” (independent ambulation for 0–5 months), and “experienced walkers” (independent ambulation for 6–12 months), developmental age significantly affected the children’s stability when walking and performing functional activities. We sought to examine how shoe structural characteristics affect plantar pressure distribution in early walkers.
Torsional flexibility was evaluated in four shoe designs (UltraFlex, MedFlex, LowFlex, and Stiff based on decreasing relative flexibility) with a structural testing machine. Plantar pressures were recorded in 25 early walkers while barefoot and shod at self-selected walking speeds. Peak pressure was calculated over ten masked regions for the barefoot and shod conditions.
Torsional flexibility, the angular rotation divided by the applied moment about the long axis of the shoe, was different across the four shoe designs. As expected, UltraFlex was the most flexible and Stiff was the least flexible. As applied moment increased, torsional flexibility decreased in all footwear. When evaluating early walkers during gait, peak pressure was significantly different across shoe conditions for all of the masked regions. The stiffest shoe had the lowest peak pressures and the most flexible shoe had the highest.
It is likely that increased shoe flexibility promoted greater plantar loading. Plantar pressures while wearing the most flexible shoe are similar to those while barefoot. This mechanical feedback may enhance proprioception, which is a desirable attribute for children learning to walk. (J Am Podiatr Med Assoc 103(4): 297–305, 2013)
