Effect of Impairment-Oriented and Function-Oriented Exercises on Mouth Function in Subjects with Systemic Sclerosis

Health-related quality of life in patients with systemic sclerosis: evolution over time and main determinants

OBJECTIVES

In SSc patients, disease specific determinants that influence health-related quality of life (HRQoL) over time have not been described. We aim to, in patients with SSc, (i) evaluate if and how HRQoL changes over time, and (ii) assess how different SSc domains and functional impairments contribute to changes in HRQoL over time.

METHODS

All SSc patients from the Leiden SSc cohort were included; patients with disease duration <24 months were classified as incident cases. HRQoL was assessed prospectively on an annual basis using the EQ-5D and the SF36. To assess baseline associations between clinical characteristics and HRQoL, linear regressions were performed. To identify possible associations between SSc characteristics and HRQoL change over time, linear mixed models were performed in both incident and prevalent cases.

RESULTS

In total, 492 SSc patients were included (n = 202 incident cases), with a median follow-up duration of 3.4 years. At baseline, presence of organ involvement was independently associated with a worse SF36 physical component score and lower EQ-5D score. Over time, gastrointestinal symptoms, Raynaud and digital ulcers were independently associated with deterioration of HRQoL in both incident and prevalent cases. In prevalent cases, pulmonary arterial hypertension (PAH) was associated with a decrease in HRQoL over time. Worse functioning as measured by six-min walking distance, mouth-opening, finger-to-palm distance and grip-strength contributed significantly to deterioration of HRQoL over time.

CONCLUSION

In SSc, key clinical burdens that contribute to worsening of HRQoL over time include digital ulcers, Raynaud and gastrointestinal involvement. In addition, PAH is a significant burden in prevalent disease.

The effect of a home-based orofacial exercise program on oral aperture of patients with systemic sclerosis: A single-blind prospective randomized controlled trial

OBJECTIVES

This study aims to evaluate the effect of a home-based orofacial exercise program on the oral aperture (OA) of systemic sclerosis (SSc) patients.

PATIENTS AND METHODS

This single-blind prospective randomized controlled study performed between March 2017 and January 2019 included 56 SSc patients (3 males, 53 females; mean age 52.9±10.6 years; range, 31 to 70 years) with an OA of <40 mm. Patients were divided into two groups. Group 1 (n=28, mean age 53.8±9.6 years) was given orofacial exercise program twice a day for one month in addition to oral hygiene care advices, followed by no activity for the next month. Group 2 (n=28, mean age 50.0±11 years) received oral hygiene care advices for the first month followed by the same exercise program for the next month. Patients' OA was measured at baseline, and at first and second months.

RESULTS

After the first month, OA increased in Group 1 (p<0.001), whereas no change was observed in Group 2 (p=0.579). At the end of two months, there was no additional increase in Group 1 (p=0.352), while there was a significant increase in Group 2 (p<0.001). There was no difference between OAs of the groups at the end of the trial (p=0.564).

CONCLUSION

Our results suggest that home-based orofacial exercise program improves OA of SSc patients.

Analysis of Labial and Lingual Strength among Healthy Chinese Adults in Taiwan

This study collected 11 parameters regarding the labial and lingual strength for maximum isometric and swallowing tasks among 150 healthy Chinese adults in Taiwan. Measurements were performed using the Iowa Oral Performance Instrument (IOPI). All of the labial and lingual strength parameters were measured three times. The maximal value of three trials represents the pressure of every parameter. The overall mean (±standard deviation) and maximum isometric pressures of the lips, anterior tongue, and posterior tongue were 24.81 ± 5.64, 55.95 ± 14.13, and 53.23 ± 12.24 kPa, respectively. The mean value of posterior tongue strength was less than that of the anterior tongue by approximately 5%. The percentages of maximum isometric tongue pressure during the swallowing of saliva and water were 85% and 80% for the anterior tongue and 90% and 81% for the posterior tongue, respectively. The average endurances for the anterior tongue and posterior tongue were 13.86 ± 7.08 and 10.06 ± 5.40 s, respectively. The maximum isometric pressures were greater than both the saliva and water swallowing pressures, and the saliva swallowing pressures were greater than the water swallowing pressures. A value of 33 kPa in maximum isometric pressure could serve as a demarcation of weak tongue strength for healthy Chinese adults. As for the repeated trials of labial and lingual strength, there were no statistically significant differences for any of the pressures obtained from the 11 labial and lingual strength parameters. The normative data can be used for the objective assessment of labial and lingual strength in healthy Chinese adults.
