Can boxing training improve Parkinson reaction times?
NEW YORK – A small pilot study has shown that patients with Parkinson’s disease who participated in the Rock Steady Boxing non-contact training program may have faster reaction times than PD patients who did not participate in the program, according to a poster presented at the International Conference on Parkinson’s Disease and Movement Disorders.
“The novelty of this is that it shows how Rock Steady Boxing and exercise programs that use sequences and the learning of sequences could possibly help slow the decline, or maintain a level of functioning longer, in Parkinson’s disease,” said Christopher McLeod, a second-year medical student at New York Institute of Technology (NYIT) College of Osteopathic Medicine, Old Westbury, N.Y.
Rock Steady Boxing is a non-contact program tailored to Parkinson’s patients founded in 2006 by Scott Newman, an Indiana lawyer who was diagnosed with early onset Parkinson’s at age 40. The regimen involves intense one-on-one training centered around boxing. Rock Steady Boxing offers classes from coast to coast in the United States and in 13 other countries. Mr. McLeod is a volunteer at the NYIT chapter of Rock Steady Boxing in Old Westbury, N.Y.
Mr. McLeod studied 28 PD patients – 14 who had been taking Rock Steady Boxing classes at NYIT for at least 6 months and 14 controls. The goal of the study was to evaluate if the Rock Steady Boxing participants showed any improvement in procedural motor learning. His coauthor was Adena Leder, DO, a faculty neurologist and movement disorder specialist at NYIT,
“What’s new about this research is the procedural memory component and the Rock Steady Boxing program is just more of the vessel, so to speak,” Mr. McLeod said. “This is a pilot study. We wanted to see if Rock Steady Boxing would show benefits in these patients. There are some trends in my research that [indicate] it would; it did not have statistical significance, but we did see trend lines.”
The researchers used a modified Serial Reaction Time Test (SRTT) composed of seven blocks of 10 stimuli each with 30-second breaks between blocks. Blocks consisted of a random familiarization block, four learning blocks repeating the same sequence of stimuli, a transfer block of random stimuli, and a posttransfer block presenting the same sequence of stimuli from the four learning blocks.
They assessed procedural learning by comparing the reduction in response time over the four identical learning blocks as well as by comparing changes in response time when the subjects were subsequently exposed to the random transfer block.
Experienced boxers demonstrated faster reaction time over the four learning blocks, ranging from 795.32 vs. 906.89 ms in the first learning block to 674.79 vs. 787.32 ms in the fourth learning block (P = .19). In the random sequence transfer block, controls showed a 93.5-ms decrease in median reaction time vs. a 27.3-ms increase in reaction time of experienced boxers. One possible explanation the investigators noted is that the controls simply got better at reading the stimuli over time without actually learning the repeated sequence.
Mr. McLeod noted that a typical Rock Steady Boxing session starts with a warmup and stretch, then learning the boxing stance with the nondominant foot back, shoulders over the body and the head over the feet. The boxing moves involve sequences of different punching combinations — jab, jab, cross; left, left, right; jab, cross, hook. Then the class divides into separate circuits for boxing and exercise. The boxing circuit involves punching the speed bag – the small, air-filled, pear-shaped bag attached to a hook at eye level – as well as heavy bag and partner-held focus mitts, all with the aim of reinforcing the learned sequences. The exercise circuit focuses on muscle training and exercise with the goal of improving balance and gait.
“The boxing sequences help not only with cognitive ability but motor control,” Mr. McLeod said. “The program also helps with some of the nonmotor aspects of Parkinson’s disease. Depression is almost synonymous with Parkinson’s disease; this brings people together and builds camaraderie.”
Mr. McLeod said he hopes the research continues. “I’m hoping that this can be a jumping-off point for research going forward with procedural memory, Parkinson’s, and Rock Steady Boxing or programs like it,” he said. Future research should involve more subjects, measure improvement within same subjects who participate in the program, and account for variables such as age and gender.
